Do hardware RAID card make sense in 2025? In this video I compare Hardware RAID with ZFS and MDADM to see how they differ in terms of performance, CPU Usage, This needs to be upvoted. However the study also Zfs fans will try to push that, but without a pool (giving up the array), zfs loses a lot of it's values imo while making things more complex. In 2018, I reported ZFS performance results based on version 0. Mar 28, 2025 · One of the key differences between BTRFS and ZFS lies in their approach to implementing RAID levels. zfs is more widely used in the self hosting / nas world.

Btrfs performance better than old Btrfs: Check git pull btrfs update. The total throughput is better than with ZFS (40k vs 60k), but the jitter is more severe. All my servers and VMs, except the NAS are on xfs. Now, we are about to find out Btrfs vs. I, personally, and very subjectively, prefer xfs. Finally, even if XFS can also create snapshots as ZFS does, the performance of the snapshots is considerably better in ZFS. Regarding community: my personal experience is, BTRFS community is smaller, but more prosumers and experts are willing to help. Sure, Btrfs and Bcachefs will be much more flexible, but ZFS alone has such a massive head start and much more investment (the "billion dollar filesystem"), and even with the last benchmarks from Phoronix, even Btrfs still outperforms Bcachefs it in a lot of cases, which is saying a lot because Btrfs is no performance king. The array is readily expandable (an essential consideration for you media data hoarders out there as your collections grow! Jan 3, 2025 · Your choice of which filesystem to use can play an important role in optimizing performance, reliability and data integrity. Developed by Oracle, Btrfs aims to deliver advanced features while providing robustness and flexibility. Jan 11, 2024 · Btrfs usually is not a problem on the array, since they are single device filesystem, 95% of my array disks are btrfs for like 6 years or more and never had a problem, it can be more of a problem with multi device pools if used with unreliable hardware and users don't monitor them for errors, or if there are RAM issues, btrfs is also very susceptible to bad RAM, much more than XFS. Feb 2, 2015 · Virtual machines storage performance is a hot topic – after all, one of the main problem when virtualizing many OS instances is to correctly size the I/O subsystem, both in term of space and speed. Allerdings hatte BTRFS eine deutlich bessere Leistung bei kleinen Dateien als EXT4. Btrfs doesn't have as many performance features that ZFS has, and the ones it does have are bad to use with RAID (ie NOCOW), however there are some if you need it. The last one is not in use for now.

This comprehensive, 2500+ word guide will compare the two advanced filesystems to help you pick the right solution for your needs. ZFS does offer some advantages (similar to all pure-RAID systems), but if I wanted pure RAID, I would have built a RAID server as opposed to an UnRAID server. Btrfs has several advantages over ZFS and EXT4/EXT3 Oct 18, 2023 · ZFS and BTRFS have some similarities (ZFS having much more functionality, and BTRFS being in the "test" phase, not necessarily recommended). But I am trying out different scenarios and will eventually make a choice. However, in some scenarios, copy-on-write can impact write performance in Btrfs. Btrfs Async buffered write: More than 2x performance. More complex systems requiring better performance and storage capacity might be better using the ZFS file system. Old Btrfs from Kernel 5. The 4k advantage for btrfs could have to do with the fact that my btrfs ended up with 4k “Sector size” by default, whereas my zfs setups always had at least 64k recordsize (I rather not go lower as that would impact compression negatively). Verteilte Systeme wie Ceph oder Gluster gehen völlig anderen Ansätzen nach und kommen am Ende auf ähnliche Features. ) The problem (which i understand is fairly common) is that performance of a single NVMe drive on zfs vs ext4 is atrocious. Making matters worse, ZFS also is slower than other RAID implementations (due to it's rich feature set. MD RAID does NOT guaranty data integrity at all. The performance of Btrfs and Ext4 on SSDs is influenced by their design and optimization for solid-state drives: Wear Leveling and TRIM Support: Ext4: Ext4 supports TRIM operations, which help maintain SSD performance by allowing the drive to manage free space more efficiently. For cache, I always suggest to run 2 disks in raid1, and keep it to btrfs for now myself (years of testing vs new half implemented tech with zfs). With the initial create test in the compile benchmark, the performance of ZFS was over 3.

If you make one 90 drive vdev, you are more or less limiting yourself to the iops of a single disk. 1 performance. If a one disk in a MD mirror contains/returns corrupted data, this goes unnoticed and you cannot tell wich side of the mirror is the correct one! BTRFS would detect and fix this automatically. It is easy to get a project that has 80% similarity on the surface, but then you spend the same amount of time from 0 - 80% on the last 20% and edge cases. This is a quirky FS and we need to stick together if we want to avoid headaches! Totally agree. The amount of engineering hours went into ZFS is insane. Of course performance is not the only thing to consider: another big role is played by flexibility and ease to use/configure. 性能：Btrfs和ZFS的性能都取决于具体的使用场景和配置。Btrfs在某些情况下可能会比ZFS性能更高，但ZFS在大规模数据存储和处理方面表现更出色。 3.

It is currently the main competitor to the ZFS file system. Unraid is just good old xfs (or btrfs, but that also has/had it's issues, and now you can do zfs, even on individual array disks, something that might be the best solution going forward) with some parity magic on top of it. It's designed to offer improved performance, data integrity, scalability, and advanced snapshot capabilities compared to traditional file systems like ext4. While ZFS may have a slight edge in terms of performance and data integrity, Btrfs is a viable option for Linux users looking for a native file system solution. BTRFS hatte auch etwas höhere Latenz als EXT4, was bedeutet, dass es länger dauerte, bis Dateien auf dem Dateisystem zugegriffen werden konnten.

What are the quality-of-life differences between the file systems? Example: Dropbox is hard-coded to use ext4, so will refuse to work on ZFS and BTRFS. I hope that bcachefs will evolve into a stable & high performance fs, but that a long way off. They have not only tested the transactions per seconds, but also the jitter which file systems have when doing stuff. In practice, I don't consider the Btrfs slowdown really relevant for desktop usage on an SSD, VM performance aside. ZFS. Jan 11, 2025 · I plan to maybe reformat more array drives to BTRFS (now all are XFS except one), but now decided to test, because I read a few posts on unraid forum from moderator, he also use BTRFS in main array for years without issues, but he mentioned a few times that ZFS is more mature or smt like that, he meant that any hardware instability can corrupt (potentially) data on BTRFS, but funny the same The biggest concept to grasp with ZFS and Btrfs is that ZFS and Btrfs expect disks to be disks. EXT4 SSD Performance. Mar 18, 2024 · Being a copy-on-write filesystem, ZFS also avoids problems that can occur during erroneous journal recovery.

They are well supported and offer good performance, but don’t have some of the modern features that the other two file systems offer. There's a ton of information on both file systems - ZFS and BTRFS. ZFS pools typically necessitate all disks spinning while in use, leading to increased power consumption compared to a regular Unraid array. On Linux you're better off with ext4 on LVM raid. By means of Raid, the pool is protected against the failure of a disk and the storage space can be expanded at any time by means of additional disks. 2 kernel plus providing a fresh look at the ZFS On Linux 0.
