File Systems | Which One is the Best? ZFS, BTRFS, or EXT4

Let's go over File Systems in this video. We will determine which one is the best ZFS, BTRFS, and EXT4. Each one might work for you based on YOUR needs! .

I remember when I started using GNU/Linux over 20 years ago and I couldn't find a defragmenting program in the whole distro. I actually thought that was a bad thing. Hilarious.

Tldr:
ext4: basic functionality, little configuration, low overhead
btrfs: advanced features (checksums, compression, RAID), mostly for personal use (not as well tested as zfs)
zfs: lots of features, great reliability but complicated and resource intensive

In (4 drive) RAID 10, if one drive is failed, there’s a 1-in-3 chance that a second drive failure will take out the whole array. RAID 6 doesn’t have this risk.
Also, when an array has more than 4 drives RAID 6 starts to make even more sense, as you can get more useable space out of the drives while still having two-point-failure redundancy.

1:53 That monitor in the back synced up perfectly to his words XD

[joeybeauvais-feisthauer]

Thank you for the info about filesystems. However that rant on RAID 5 and 6 was entirely unwarranted, unsubstantiated, and I would say flat out wrong

[mendess]

Can you make the 10 min rant on why ntfs is bad?

When it comes to desktop, ext4 is good enough for pretty much everything. It's super performant, fairly robust, and really simple to setup.

I hope for more detailed video comparing files systems in features and performance.

I've used ZFS, but the fact that Btrfs is a native Linux filesystem made me switch to it. Spanshots are awesome but I regularly sync them to an external backup drive using btrbk utility.

If I were the US government, I’d make a one-time cash payment to Oracle to release ZFS to open source. Kinda like the interstate freeway, putting all our business data on a better file system could save us all from disaster. Then get our power grid and other critical systems on ZFS.

This is the first video I've seen of yours. Your home-grown background is awesome. It's clear you put plenty of effort into setting it up. Well done!

[AndyRipley]

First time watching your videos but there's some misinformation here. RAID 6 doesn't use a hot spare. It's uses striping across the disk with dual parity instead of single parity that RAID 5 uses. Next in a 4 disk RAID 6 you will still gain 2X read speed but no gains in write speed. However, with most home users utilizing Gbit still, the performance benefits of RAID 10 will probably go unnoticed but with an increase in fault tolerance. Since you brought up the enterprise I'll address that as well. Before my current job (no longer dealing with storage), I used to mostly use RAID 50 or 60. This allows for a heavy increase in read speed (depending upon number of drives and RAID parity) which is what most enterprise environments require. If RAID 10 was ever used, it was used for environments that needed a large amount write speed (Big Data as an example). However, most large enterprises are moving to flash storage which would remove any reason to still use a RAID with such little fault tolerance.

Forget the three letter acronyms,
name a filesystem BACONfs and everyone will want to run it

I think raid 6 makes more sense to use with more drives. Like 6 drives or 8 drives.

[Maritims]

I'd never thought much about filesystems until I started noticing very big compile time differences in Windows and Linux but with the same hardware. Compiling the same source code in Windows would take minutes while doing it in Linux would take seconds.

[DopePhizh]

Sweet. I asked you recently about ZFS and now there's a video talking about it. Thanks.

[dant]

5:48 *OMG* he's clueless about raid
He gives some really bad advice people. Please look this topic up yourself.

[wheezybackports]

I like the dark subtle joke about ReiserFS at the end. You get my approval now.

[deanlawson]

EXT4 for me.. It's everywhere, it's been around for a long time, it's rock-solid stable.. What's not to like??

[hammerheadcorvette]

I use XFS, for moving files around on a partition it's faster than EXT4, and taking into consideration SSD storage because of the higher IOPS it's a no brainer
