The benchmark results of three most common file systems under Linux environment were given in this paper. On the other hand BTRFS, while mainlined, has many important issues and performance problem (the common suggestion for databases or VMs is to disable CoW which, in turn, disabled checksumming - which is, frankly, not an acceptable answer). for data security and integrity zfs is the best. Ext4 provides more flexibility in terms of data storage. 0 File-System Benchmarks: Btrfs vs. XFS and ext4 aren't that different. This is not ZFS. We will determine which one is the best ZFS, BTRFS, and EXT4. It you have huge hard drives, BTRFS supports up to 16 times larger size than 1 EXT4 partition. Você deve ativar as cotas na montagem inicial. 1 fell slightly short of the Linux file-system performance. 84 nvme drives split up into a small ext4 volume and the rest is btrfs. As the load increased, both of the filesystems were limited by the throughput of the underlying hardware, but XFS still maintained its lead. g. In today's video, we will talk about the 4 Major Linux File Systems. 7. For BTRFS, the overall throughput is fairly low (~30k tps), while the jitter is somewhat better and worse than for EXT4/XFS at the same time. And I don't know if btrfs is right thing for my server. ZFS combines a filesystem and volume manager. 240GB SSD formatted as EXT4 for main OS. Moreover, the ext4 is more beneficial when the. Various benchmarks have concluded that the actual ext4 file system can perform a variety of read-write operations faster than an NTFS partition. There’s very little difference between EXT4 and XFS, both in total throughput and behavior over time. Backups and CoW, are why I use btrfs. 0 SSD testing ran into a strange performance drop while Btrfs. An anonymous reader writes "Phoronix has published Linux filesystem benchmarks comparing XFS, EXT3, EXT4, Btrfs and NILFS2 filesystems. So for a large video collection, I think I will stick with ext4 still. Maybe adding Btrfs compression would be negligible outside of storage benchmarks. ran defragment utility to compress all existing files. This is just an additional protection. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4, F2FS, and XFS file-system benchmarks on a speedy WD_BLACK SN850 NVMe. In this article, we will have a look at deeper details at these file systems comparatively including EXT4 vs XFS, EXT4 vs EXT3, BTRFS vs EXT4 as well as ZFS vs EXT4. It is backward-compatible with older versions of Ext. On the NVMe SSD, the four-thread FS-Mark was the fastest on XFS followed by Btrfs. btrfs seems to write more data to a disk than ext4. Đảm bảo dữ liệu khi backup. How do the major file systems supported by Linux differ from each other? Compared to Ext4, XFS has a relatively poor performance for single threaded, metadata-intensive workloads. With Bcachefs core development being done and the possibility of this file-system being mainlined soon, here are some fresh benchmarks of this file-system compared to Btrfs, EXT4, F2FS, XFS, and ZFS On Linux. XFS 和 ext4 的比较. My home file share runs zol because I prefer zfs to btrfs and run it at work a lot so I'm much more comfortable with it. Btrfs（技术预览）" Collapse section "6. 0 NVMe SSD was used for the benchmarking of these file-systems in different desktop use-cases. In Windows NTFS is used, while in Mac OS it is HFS, perhaps these will sound familiar to you, especially the typical FAT or its variants for. XFS. If you're on HDD and you need the ability to shrink the fs, then use EXT4, but you lose any COW benefits. Btrfs vs Ext4. With not having the time to conduct the usual kernel version vs. But I would still refrain from using it on the deck due to the case folding trouble. • 3 mo. F2FS vs. A number of Phoronix readers have been asking about some fresh file-system comparisons on recent kernels. Thanks. EXT4 vs. Built By the Slant team. Linux File System Comparison: XFS vs. 如果您追求高度的数据完整性和强大的快照功能，Btrfs可能是更好的选择。. 04 Disco Dingo was running on the Threadripper setup while using the Linux Git kernel from the mainline PPA. I understand if I use zfs/btrfs i will miss out on any data redundancy features but maybe pick up some added features like better consistency, snapshots, ect or should I just stick with ext4. File Size: Ext4 supports file size up to 16 TiB, while Btrfs. Btrfs provides checksums for data and metadata, ensuring enhanced data integrity. More uniquely, checksumming can detect errors in the data itself. It is suitable for PC platforms and network. One of the main reasons the XFS file system is used is for its support of large chunks of data. For reducing the size of a filesystem, there are two purported wats forward, according to xfs developers. For a side-by-side feature comparison of the major file systems in SUSE Linux. brown2green. the COW which saves alot of space and increases the speed. Files less than ~2KiB can be stored in the metadata section (“inline” in the b-tree nodes), so as not to waste most of a block. Both are suitable for everyday use, but it's worth noting that ext4 partitions. XFS has a few features that ext4 has not like CoW but it can't be shrinked while ext4 can. XFS. Let’s go through the different features of the two filesystems. Ability to create large volumes of up to 1 PB 1. Partition Size: Ext4 supports partition size up to 1 EiB, while Btrfs supports partition size up to 16 EiB. Btrfs（技术预览）" 6. Ext4 is the fourth version of the Ext (Extended) File System for Linux and is probably the most well-known file system for Linux out there. XFS doesn't have any RAID, while Btrfs RAID is not yet completely stable and is in its early days. But EXT4 is mature, rock solid, and completely reliable, and the standard for most of the linux world. The check task is involves reading roughly 2000 small files in their entirety and performing some processor intensive tasks on them. But they come with the smallest set of features compared to newer filesystems. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4,btrfs is also slower in some benchmarks but I very much doubt thats visible in normal use. ext4 is not recommended. Performance: Ext4 performs better in everyday tasks and is faster for small file writes. Potential for data loss: While btrfs has features to protect against data loss, these features can be complex to configure and may not always work as intended, leading to the possibility of data loss. Như vậy, chúng ta có thể dễ dàng kết hợp các phân vùng định dạng Ext2, Ext3 và Ext4 trong cùng 1 ổ đĩa trong Ubuntu để tăng hiệu suất hoạt động. I see that it says multiple btrfs snapshots are not supported. Back when Bcachefs debuted in 2015 I ran some initial. 迄今为止，对于桌面系统而言，ext4 似乎是一个更好的选择，因为它是默认的文件系统，传输文件时也比 btrfs 更快。. sorry, i got that second sentence wrong. Snapraid says if the disk size is below 16TB there are no limitations, if above 16TB the parity drive has to be XFS because the parity is a single file and EXT4 has a file size limit of 16TB. Ext4 is probably the final evolution of the ext filesystem (which started with ext, then ext2, ext3, and now ext4). Ext4 파일 시스템. For these reasons, Fedora has made BTRFS the standard filesystem in their newer releases. So I moved everything off of it and formatted it into XFS and ate the 0,5% space loss for peace of mind. Both Btrfs and Ext4 have their own advantages. Ext4 fs can read and write to Ext2 or Ext3 file systems, but the Ext4 it is not compatible with Ext2 and Ext3 drivers. Running this fio command, I get about 2. Subvolumes do not have a size, so the Desired. Table of Contents. Both. NTFS. But btrfs is not by any stretch the default Linux file system. XFS and btrfs are two advanced file systems for Linux that offer significant improvements over ext4. 4. Edit: fsdump / fsrestore means the corresponding system backup and restore to for that file system. XFS is optimized for large file transfers and parallel I/O operations, while ext4 is optimized for general-purpose use with a focus on security. Thanks! In that case, your choice is simple. This is because BTRFS is optimized for handling small files, while EXT4 can struggle with multiple small files due to its delayed allocation. But shrinking is no problem for ext4 or btrfs. It lived enough, time to move on. XFS vs Btrfs. Ability to create large volumes of up to 1 PB 1. In most cases that’s EXT4, but for Fedora, OpenSuse and maybe a few others it’s btrfs. as @Neoon pointed out ext4 (on your mdraid) works just fine, for that you can rather discuss the usage of raw vs qemu, which driver (virtio, scsi,. Following my post MySQL/ZFS Performance Update, a few people have suggested I should take a look at BTRFS (“butter-FS”, “b-tree FS”) with MySQL. Also, server raid originally md raid5 (4x4TB NAS drives) with XFS had taken all day to build, but creating btrfs-raid10 was seconds. In the case of the Intel 900p SSD, the XFS results were too fast to accurately measure while EXT4 and F2FS took just two seconds to complete while Btrfs took six seconds. Utilice. Recommended for general use. Tweaking the config is easy if you've figured out how to build and load your own kernel. Neither of the filesystems is better supported by OMV4 or OMV5. ZFS is an advanced filesystem and many of its features focus mainly on reliability. 再將資料再回存到 NAS, 這部份會花費很多時間. EXT4. Checksumming, along with copy-on-write, provides the key method of ensuring file system integrity after unexpected power loss. On a slow Linux box with an ext4 filesystem, the same operation takes less than a second. BTRFS solves all the problems I had so far: supports online resizing - both extending and shrinking. Provides good performance for many enterprise work load, and probably some desktop ones too. All my systems (4) have been using BTRFS for some time now without any issues. The fourth generation File System of the Ext (Extended) file system family. Personal data is irreplaceable. We would like to show you a description here but the site won’t allow us. Bcachefs is the file-system born out of the Linux kernel's block cache code and has been worked on the past several years by. EXT4: Alternative File Systems for Linux Operating Systems. XFS and ext4 now calculate a checksum on metadata and their journal files. I've read and have anecdotally (not scientific and could be affected by other things) experienced Btrfs being slower than ext4. 无论您选择哪个文件系统，都要确保进行适. The major difference between ext4 and XFS file systems is that the ext4 file system works better for fewer size files (single write/read thread) while the XFS works more efficiently for larger files (multiple read/write threads). one of the still “beta” features of btrfs. It’s an improved version of the older Ext3 file system that includes a lot of great features, including ones for Solid State Drives (SSDS). For example it's xfsdump/xfsrestore for xfs, dump/restore for ext2/3/4. OMV4 or OMV5. ext4 is not recommended. It was also 164% faster in post-snapshot reads and 17% faster in post-snapshot writes. Linux File-systems were tested on NVMe SSD including EXT3, BTRFS, EXT4, XFS, and ZFS from the mainline kernel of Linux 4. Ext3 and Ext4 perform better on limited bandwidth (< 200MB/s) and up to ~1,000 IOPS capability. To mount the XFS file system so that it uses the external journal, specify the -o logdev=device option to the. A tool for managing BTRFS and LVM snapshots. Depending on why you want btrfs, you could run zfs. To reserve an external journal with a specified size when you create an XFS file system, specify the -l logdev=device,size=size option to the mkfs. Offizieller Beitrag. If it is only about reliability and you're in doubt, go with ext4, imho. Fwiw, I think XFS still handles huge files better than EXT, so there are reasons to use it. Have snapper to create pre/post BTRFS and LVM snapshots. So now I can boot up into a snapshot. Bảo vệ dữ liệu. I think in many ways btrfs is the better filesystem, but I seem to have noticed that it takes longer to copy data than on ext4. org. 4. XFS vs. Each of the tested file-systems were carried out with the default mount options in an out-of-the-box manner. I’ll take XFS and/or EXT4 any day over rolling another btrfs filesystem that isn’t stable, but has a bunch of gimmicky features any day of the week. ZFS also has more options for caches and such things than EXT4. By far, XFS can handle large data better than any other filesystem on this list and do it reliably too. 88. In the past, I have often seen statements that EXT4 is better for gaming than XFS. In Summary, ZFS, by contrast with EXT4, offers nearly unlimited capacity for data and metadata storage. BTW, transparent compression can offset much of the performance penalty between using a fs like btrfs or ZFS and a more traditional fs like ext4 or xfs, depending on your workload. So for a large video collection, I think I will stick with ext4 still. removes the need for LVM and thus eliminates 1 layer for filesystem-ing (if that’s a word) On top of that, in 2008, the principal developer of EXT3 and. It utilizes a b+tree structure instead of the traditional linear layout found in most filesystems today, allowing it to better manage larger datasets more efficiently than other systems like ext4 or Xfs. However, BTRFS had significantly better performance with small files than EXT4. org and zfsonlinux. EXT4 vs. There won't be any noticeable difference. Btrfs 與 EXT4 常見問題解答. And ext3. I would stick with ext4 for the OS. The thing is I'm putting /home in a separate HDD. El ext4 y xf. We will determine which one is the best ZFS, BTRFS, and EXT4. Ability to shrink filesystem. BTRFS has (by far) the better ecosystem of tools and utilities. 10 4. EXT4 vs. En el caso de los servidores NAS de Synology, tenemos la posibilidad de configurar EXT4 o Btrfs, de hecho, en el asistente de configuración de los volúmenes podremos elegir entre uno y otro sin ningún problema. ZFS certainly can provide higher levels of growth and resiliency vs ext4/xfs. Same as with ZFS. It you have huge hard drives, BTRFS supports up to 16 times larger size than 1 EXT4 partition. For example btrfs supports transparent file compression. This article provides a detailed comparison of the three file systems to help you decide which one is the best for your needs. I had no bad experience myself with btrfs so far, but still have not tried it with anything more complex than raid1 over a long time and while I assume many horror stories out there are just deprecated as btrfs keeps improving, it can do a lot more than ext4. But yeah, it's (BTRFS) a more complex filesystem with a bottomless pit of asterisks and gotchas attached to it, EXT4 is much more limited in scope and much simpler from a design perspective. With not having the time to conduct the usual kernel version vs. Windows users don’t have much of a choice regarding a file system. It also wasn't formatted with -m finobt=1 which is a game-changer for XFS performance with small files and heavy metadata updates. Why? Files are the most important bits of data on your hard drive. Pros: Individual file size: 16GB to 2TB. However, Ext3 lacks advanced file system features like extent blocking mapping, dynamic allocation inode, and defragmentation. But. For example it's xfsdump/xfsrestore for xfs, dump/restore for ext2/3/4. It's a 64-bit, journaling filesystem that has been built into the Linux. Crypto2. Tích hợp Cloud Station Server, Drive mang hiệu quả cao. Btrfs has been a stable part of the Linux kernel since 2013, and you can reformat your hard drives using the file system today. It was later developed for Linux. ZFS brings robustness and stability, while it avoids the corruption of large files. Small to Medium Enterprises: While ext3 suffices for businesses with modest data needs, scalability visionaries would do well considering ext4. It provides an unlimited subdirectory. BTRFS is an actual file-system. Unless you're doing something crazy, ext4 or btrfs would both be fine. Windows users don’t have much of a choice regarding a file system. It supports large file systems and provides excellent scalability and reliability. 1 interface. Regarding boot drives : Use enterprise grade SSDs, do not use low budget commercial grade equipment. Tuy nhiên, đối với phân vùng /home chứa các file cá nhân, openSUSE đã quyết định sử dụng hệ thống file XFS thay thế. XFS is very well established and changing slowly, and the same can be said for EXT4. 7. Data Colossi & Data Centers: Ext4 is non-negotiable for handling extensive data transactions. Ext4 is a journaled filesystem, which simply means that it “journals” the location of the files on the disk and keeps track of the changes on the disk. The way you describe this workload, I think it is not very demanding. Btrfs trails the other options for a database in terms of latency and throughput. btrfs is da bomb yo. It supports all. Tùy chọn mặc. Btrfs Benchmarks comparison, here is a wider look at mainline file-systems on the Linux 4. 3. Phoronix has a ton of reviews, Google for them. That's right, XFS "repairs" errors on the fly, whereas ext4 requires you to remount read-only and fsck. So please enlighten me, where is btrfs better and where is it worse or just significantly different than ZFS. BTRFS bietet, mal abgesehen von der Möglichkeit einer Inline Deduplizierung, beinahe alle Features von ZFS. In summary, both Btrfs and Ext4 are good options for your NAS, and the choice between the two ultimately depends on your specific needs and use case. A continuación, os vamos a explicar brevemente las principales características de EXT4 y de Btrfs. Btrfs, EXT4, F2FS, and XFS were tested in their out-of-the-box state / default mount options. 另外，我们常说的file对象，它用于关联进程和dentry对象的. On the other hand, for Linux/Unix-based devices, it might be a bit of a challenge choosing one among many options. Btrfs is one of the most popular newly created file systems, and was. And the I discovered how many tools are out there to recover data from EXT partitions and how few for XFS. However, when we review EXT4 vs BTRFS, here’s the downside: BTRFS has disk and volume management built-in, while EXT4 is a “pure filesystem”. ZFS likes eating RAM. Just so perfect to roll back for some games and modding. In the time since I chose ext4 for these systems, btrfs seems to have come a long way, so the choice may be harder today. Choosing between them can be difficult as each has its own advantages and disadvantages. Share. So if you have a SSD and care about the wear of that then. I have 6 disks so I have created 3 logical disks, 2 SSDs each - just for testing. If you think that you need. 0 File-System Benchmarks: Btrfs vs. BtrFS looked promising, but last I checked it still couldn't be trusted in RAID modes. Interestingly, the first version of the Ext4 filesystem, the Extended filesystem (“Ext”), came out in 1992 for the Minix OS. It was later developed for Linux. However ZFS does come at one major downside, it needs more resources in just about every way one can imagine, ZFS is best with more disks, more RAM, more CPU, more Bandwidth, more SSD’s for caching…. e. It self-describes as "stable", as of. • 2 yr. Both Btrfs and Ext4 have their own advantages. Both filesystems provide COW but XFS fragments less (and it's data cow only so no snapshots, only reflinks). The only time there were issues was when my RAM sticks went bad and btrfs detected it and put my FS into read-only mode to prevent corruption. The PostgreSQL database server ran well particularly on EXT4 and XFS while F2FS on the USB 3. Let's go over File Systems in this video. Unix, etc. Each one might work for you based on YOUR needs! Supp. We may have lengthy talk on ext vs XFS vs f2fs and btrfs vs zfs and there are many more points to be mentioned, but for regular users. XFS scales much better on modern multi-threaded workloads. Having this opportunity I wanted to put some hard numbers to my previous observations regarding ext4 vs Btrfs performance on my T430 running Qubes OS R4. . EXT4, Btrfs, and XFS were tested on the Ubuntu mainline kernel PPA hosted Linux 3. • 3 mo. EarthyFeet. Or when it came to testing the single Seagate IronWolf 6TB HDD performance, Btrfs and EXT4 were performing about the same with a. (For example, you might have an ext4 root filesystem, but store most of your data on a zfs or btrfs pool. Most distros continue to default to ext4. . GameStop Moderna Pfizer Johnson & Johnson AstraZeneca Walgreens Best Buy Novavax SpaceX Tesla. Dropping performance in case with 4 threads for ext4 is a signal that there still are contention issues. Ext3 and ext4 have some very specific differences, which I'll focus on here. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4, F2FS, and. If you are running a more stable system like Dabian based Linux EXT4 is a better choice because it's faster file system but not as easy to revert. Ext4 focuses on providing a reliable and stable file system with good performance. However benchmarks test quite narrow parameters which may not be reflected by running an OS. Now Fedora just needs to implement it properly like openSUSE. SSD optimization. AdamV158. We recommend btrfs for testing, development, and any non-critical deployments. Hi I have used BTRFS for the first time since March 2023 on my internal archives directory. In this Video we are going to cover Linux File System Types - Ext2,Ext3,Ext4,XFS,BTRFS | Linux File Systems Explained | Linux Tutorial for Beginners #linuxt. Ext4 has journaling on by default, and new users likely won’t know how to disable it to save read/writes on their SSDs. Both cases, a mechanical drive. Btrfs' RAID on Linux 5. Reasons why I avoided btrfs:Btfs not meant to replace ext4, they are in a different category, ext4 is simple, old and stable while btrfs brings new ideas and goes into very different direction. Here are some key differences between them: XFS is a high-performance file system that Silicon Graphics originally developed. Ext4 is fast and rock solid, and easily recovered on a desktop machine if things go really bad. Yes, both BTRFS and ZFS have advanced features that are missing in EXT4. Hi I never worry about it… my latest SSD SanDisk Extreme Pro 240GB has a 10 (limited) year 50GB a day warranty, Have OCZ’s with thousands of hours running btrfs all running fine. No such built-in compression support is in Ext4. Btrfs removes duplicate data from disk directly while Ext4 cannot do that, Btrfs support CoW so users can create writable and read-only. Between 2T and 4T on a single disk, any of these would probably have similar performance. On the HDD the Bcachefs performance was just behind EXT4 but doing much better than Btrfs though not nearly as fast as XFS in this. EXT4 being the “safer” choice of the two, it is by the most commonly used FS in linux based systems, and most applications are developed and tested on EXT4. EXT4 still performs better than BTRFS. 对于一些文件系统如Ext4等，在硬盘格式化时就全部确定了，而对于XFS则是动态生成的，BtrfS则是更特别的动态实现。. This is why XFS might be a great candidate for an SSD. #6. It lived enough, time to move on. If you use Debian, Ubuntu, or Fedora Workstation, the installer defaults to ext4. The Ext4 file system is a very old file system and it has been used on the Linux operating system for a long, long time. 1. Ext3 should be out, too, since it's been replaced by ext4. Reliable! I used it in Rsync mode as only my backup disk is btrfs, everything else was ext4 or XFS. Server with complex storage needs including redundancy and you need high uptime, and you have the budget. It has features that can scale better than ext4 and is even preferred over ZFS by some users. A) crater. Yes Ext4 is much easier to setup but BTRFS has its advantages. I wouldn't go for ZFS on root although it is fully supported on Proxmox 6. Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. Or btrfs, which is making some serious headway again with it becoming the default filesystem for Fedora. After a week of testing Btrfs on my laptop, I can conclude that there is a noticeable performance penalty vs Ext4 or XFS. You might also want to consider Btrfs for your array drives, but you should be aware of the potential risks. And you might just as well use EXT4. Written by Michael Larabel in Storage on 20 January 2018. are two different decisions you have to make. That filesystem is now xfs. Indie games often too get fair amount of gain. Allerdings hatte BTRFS eine deutlich bessere Leistung bei kleinen Dateien als EXT4. XFS与Ext4性能比较. 여러 가지의 HDD를 장착하여 사용을 하신다면 사진이나 중요한 자료들을 저장하는 드라이브에는. because it spans multiple partitions, it's less likely to fill up your hard drive. It uses a default file system for Linux distribution, including Debian and Ubuntu. You get awesome functionality like cp --reflink and btrfs subvolume snapshot -r and btrfs send and btrfs receive . File-systems tested on the NVMe SSD included Btrfs, EXT4, F2FS, XFS, and NTFS. XFS, EXT4, and BTRFS are file systems commonly used in Linux-based operating systems. ZFS is great but heavy/complex, and lack of block pointer rewrite can be painful. 7 - EXT4 vs. 6. XFS, EXT4, and BTRFS are file systems commonly used in Linux-based operating systems. Btrfs was 107% faster in initial read scores and 24% faster in initial write scores. However, XFS is amazingly fast in the insertion phase as well as the workload execution phase. Because of this, and because EXT4 seems to have better TRIM support, my habit is to make SSD boot/root drives EXT4, and non-root bulk data spinning-rust drives/arrays XFS. #filesystem #ext4 #xfs #linuxExplicación de las diferencias entre sistemas de archivos, en este vídeo se comparan los 2 mas usados en GNU/Linux. Pro: supported by all distro's, commercial and not, and based on ext3, so it's widely tested, stable and proven. . So now I can boot up into a snapshot. F2FS, XFS, ext4, zfs, btrfs, ntfs, etc. Hello everyone, The time has come again for me to reinstall arch once more. ext4 or XFS are otherwise good options if you back up your config. ext4 파일 시스템은 Red Hat Enterprise Linux 5에서 사용 가능한 기본 ext3 파일 시스템의 확장된 버전입니다. to cut a long story short: If you want a common file storage between Unix and windows, exFAT is the best choice at the moment. Another point against btrfs is the insane amount of memory it uses. ago. Allerdings hatte BTRFS eine deutlich bessere Leistung bei kleinen. For btrfs you have to do most from CLI. Language: Format: Language and Page Formatting Options. It is destined to be replaced by Btrfs as the default Linux filesystem. Through many years of development, it is one of the most stable file systems. ext4. Você pode então configurar a aplicação de cotas usando uma opção de montagem. 4 EXT4 / XFS / Btrfs RAID Performance On Four HDDs Storage : 2019-12-28: Benchmarking The Experimental Bcachefs File-System Against Btrfs, EXT4, F2FS, XFS & ZFS Storage : 2019-06-25: Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS Storage : 2019-06-20: Linux 5. First up was the SQLite embedded SQL database library test. A maximum. Btrfs Benchmarks comparison, here is a wider look at mainline file-systems on the Linux 4. btrfs 当然值得尝试、但要在桌面 Linux 上完全取代 ext4 可能还需要一些时间。. The one they your distribution recommends. Btrfs lacks maturity and stability at the time of this writing but is more feature-rich compared to EXT4. This correlates with the previous experiment and the hypothesis. I've heard good things about BTRFS, and I'd use XFS but I dislike that it takes an significant % of the free-space off the bat. For personal and SOHO use, EXT4 is the most commonly used file system in Linux systems. 7 - EXT4 vs. Here are a few other differences: Features: Btrfs has more advanced features, such as snapshots, data integrity checks, and built-in RAID support. Higher scores are better. Language: Format: Red Hat Training. Linux provides the statx(2) system call interface for retrieving the file birth time for filesystems that support it since kernel version 4. Here is a quote from RHEL regarding XFS vs ext4. But not enough users follow the guide on and instead do stuff that actually makes the system worse.
