Raid 00?

[IHirs]

Is it possible to have a raid 0 setup with 4 ssds so you get 4x the speed of 1?

I don't think that's how it works, but I'm prepared to be corrected.

1) It's not even close to 4x, especially for writes.

 

2) you do not need that much speed, it will make 0 difference to you and you will be wasting money.

 

3) even if you are a video editor or do rendering as your job, NVME and no raid is a better choice for speed.

Theoretically? Yes. Practically? no. 

 

Performance increases drop sharply the more drives you add to a RAID 0 array, it's definitely not a linear performance increase. If speed is what you're after, going for a PCIe based storage solution is a better choice.

Follow up to this.  What if you made a RAID 0 with 4 drives.  then made 3 more with 12 more drives (4 each).  Then Raid 0d your 4 Raid 0 arrays.  is that possible?

 

Edit - I know linus had a similar setup with 4 RAID 5s in RAID 0 in windows....  asking if 4 raid 0s in raid0 in windows would be faster essentially.

Ok, well still its not 4x because it doesn't scale perfectly.
