N.B at 0:50 I have written RAID as "Random" Array of Independent Disks and NAS as Network "Assisted" Storage, I continued this misrepresentation throughout the video. These are typos and are NOT correct. RAID stands for *Redundant Array of Independent Disks* and NAS - *Network Attached Storage* I apologize for the confusion.
Never use RAID-0 for data you care about. It offers no redundancy, and the chance of failure increases linearly with the number of drives. If any drive dies you lose _ALL_ data on the array.
@@Channel8eight As long as you understand the risks. There will be no redundancy. Even one drive failure will result in complete data lose, and with four drives you will have four times the risk of failure.
It doesn't scale linearly, it's quadratically. Each drive you add doubles the probability of failure, so 2^n, where n is the number of drives in the RAID 0 array.
If you have a backup that is big enough, RAID 0 is fine for normal use. But for constant use with a lot of mission critical stuff, RAID 5, 10, 50, etc. are much better options.
I just made the leap. (8) 4TB Crucial P3 Plus NVME's to put in 2 OWC express's to create (2) 16TB. Wish i could afford the 8tb NVME chips. I'm also also fascinated by the NVME 2230 chips.
No, he is right 0:50 you said redundant but you wrote random Also there is too much desinformation on this video as a whole that it hurts if you know about it Specially all the NAS part, does seem you got no idea and just think a NAS is those prebuilt ones, when you can use pretty much anything as a NAS without much configuration
Thank you! You really know your stuff. You are so right about M.2 external enclosures but they vary in speed. I just made an OWC Express 4m2 enclosure with Samsung 980 PRO 2 TB X4. I used Apple Disc Utility to make a RAID level 0. It gets 2500 r/w. I also have 2 Acasis enclosures, one using a Samsung 980 PRO 2TB and the other using Samsung 990 PRO 2 TB. They both get 2800 r/w. I copied a 22 GB folder from my dinosaur Seagate 8 TB to the 4M2 and it took 2 minutes. I copied the same folder from the 4M2 to the Acasis and it took 10 seconds!! Spinning hard drives have now officially gone the way of cassette tapes.
How has that enclosure held up? Fan issues? Have the two outer M.2 drives failed due to heat? I want to go this route but keep seeing OWC hasn’t improved the issues with fans failing after 8-12 months of usage.
This video is fab! I've been thinking about making a RAID/NAS for a while as working off multiple 2.5" HDDs has gotten pretty messy. The OWC 4 bay totally checks all the boxes, as I didn't require the networking and power consumption of a NAS but do need fast speeds and RAID data redundancy!
M.2 arrays seem to be the way to go moving into the future, the speeds are simply unmatched. I will be upgrading to the OWC express 4M2 soon, so make sure you’re subsumption when that video comes out 😎
Why in the WORLD would you use rotating drives for video? I used to work in the disk drive industry and in fact moved over to engineering on NVMe drives. Rotating drives always had severe compromises for real time data. It only really got "fixed" by sticking big caches on the drives.

Glad to see a new upload! Welcome back :)

I'm giving RAID0 a go because I want to see the sort of reliability I can get from these drives overtime.

If you still want to go with RAID-0 I recommend a good backup plan.
It doesn't scale linearly, it's quadratically. Each drive you add doubles the probability of failure, so 2^n, where n is the number of drives in the RAID 0 array.

RAID is an underlying technology for data redundancy and is independent of NAS, SAN or the type of disk (nvme, SATA, SAS, etc).)
Is NAS sometimes referred to as network assisted storage or was that a slip?
You are absolutely right, that was an oversight on my end. I have addressed the errors in a pinned comment at the top of this video. Apologies.
This isn't the Channel 8 I remember from my teenage years.... oh that was tube8, nevermind

The ultimate life hack! Thanks channel 8 and welcome back!
Thanks bro, appreciate it 👊🏾
RAID stands for redundant array of inexpensive disks or redundant array of independent disks, not random... ;)
No, he is right
0:50 you said redundant but you wrote random
Also there is too much desinformation on this video as a whole that it hurts if you know about it

@@Channel8eight regardless how you got it, you wrote it wrong. BTW, that is not a typo but an erratum.
This has just come to my attention. I apologize for the confusion and misrepresentation in the slides.

Highly understandable.. bravo

Seems like a lot of users still opt for spinning disks because of the cost factor.
Ummm. NAS enclosures.
Noise, heat, vibration !!!
Utter nonsense. Get your facts correct.
