You're wrong on a few points.
In a configuration with 4 drives:
- RAID10 won't tolerate a 2 disk loss scenario where you lose a disk and its mirror.
- RAID6 will tolerate -any- 2 disk loss scenario
In a configuration with more than 4 drives:
- RAID10 becomes more capacity inefficient, it exposes 50% of available space in the array for use.
- RAID10 is limited to using an even number of disks in an array.
- RAID6 becomes more capacity efficient, it will expose capacity for (number of drives - 2)
- RAID6 can utilise even number of disks
Also:
- RAID6 does not use a hot spare, it uses 2 drives for parity, i.e. no disk is left idling.
- RAID10 is more performant at any array size
I suggest you do some research and fact check the points above, at least learn the concepts right before forming an ill informed opinion on RAID6, and even more research before spreading misinformation.
A lot of data centers use RAID6, as it is one of the most resilliant array configurations, you're the noob for not knowing about it... the irony. :)
You're welcome.

Interesting video but it did leave me with more questions than answers! It didn't really cover the actual technical differences between the file systems and -NTFS is just bad- really didn't give me much to go on. I would love to hear more about this and the technical nitty-gritty details about the differences.
Also, the bit about RAID seems incorrect: RAID 6 is when the array has dual-parity, not necessarily a hot-spare although you can add one if you wish. This in turn means two disks would need to fail before data is at risk of being lost so when you say you don't believe RAID 6 shouldn't exist I don't think you're thinking of the right RAID.
Either way, I really do enjoy these videos and am learning a lot about Linux so thank you!

I'm using XFS right now on my newly built NAS system. I got a Terramaster F2-210 on sale real cheap, so I could learn about NAS, which I knew 0 about. The little Terramaster works well for what it is, but it's not much in the way of hardware or software, so I figured I put together a computer for NAS use from hardware I have laying around. I'm trying out NAS OS's right now. First tried out FreeNas using ZFS, and really like it. I'm trying OpenMediaVault right now using XFS, and just getting that up and running now. Plan on trying UnRaid next, just out of curiosity. Been using the EXT2-3-4 since I started with Linux many years ago, and have always had great service from that filesystem.

Largely just rambling with some reference to feature comparison.
Definitely not quantitative or qualitative comparison of said file systems.
It was largely just an opinionated rant; disappointing video overall.
I watch it to the end and no more informed at the end of it.

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.

The stuff he says about RAID 5 and 6 makes me think if he's just trolling. It's that wrong. And also Raid 10 has no downsides? Well, just besides you needing double the amount of Drives. Do a Raid 5 out of 5 disks und just need one parity. In raid 10 you suddenly need 10 drives.

Umm... If you claim that RAID 1-5-6 are garbage, you need to tell why in your opinion it is. Same as ZFS, if you praise it, please at least list the most important features. Otherwise this video leaves wa-ay too many questions unanswered :(

The NTFS is almoust the greatest fs for non softraid drive because of VERY flexible user rights settings. In linux distros you have to use smb to configure +- the same rights given the smb 77? rights on it's directory in linux fs.

in 2009 I was use ReiserFs3, that was very good and fast FS, I try Reiser4, it was better than ext3 but unstable, I hear some rumors about Reiser5 and 6 in very early development, this really may be a killer fs.

Linus doesn't hate ZFS he just doesn't want to be sued by Oracle and lose the kernel Chris. Until he receives a letter from Larry Ellison that it can be included in the kernel for free licensing, he's not biting.
