Combining SSDs using RAID-0

Question

If I have 2 SSDs via SATA3, both reaching speeds of about 500MB/s, which is close to SATA3 limit, does it make sense to combine them using RAID0? I mean if the SATA3 chip can provide the 6Gb/s speed for all devices separately, there should be an improvement, right? Any experiences?

What RAID hardware/software/system are you using for this? – music2myear Dec 22 '18 at 19:08 — music2myear, Dec 22 '18 at 19:08

does it make sense to combine them using RAID0?

No. The complexity of setting this up outweighs its usefulness.

If you want to achieve a major speed increase, upgrade to a motherboard with a new M.2 slot and put in an appropriate M.2 SSD.

A current - and not that expensive - Samsung M.2 SSD achieves a maximum reading speed of 3.4GB/s - far more that a RAID-0 of two SSDs with 500MB/s can achieve.

Concerning the problem of the TRIM-command and a SSD RAID-0 this SuperUser question may add further information.

I actually have 2 M.2s here :), I just happen to have also 2 normal SSDs, one of them is redundant now, so I'm thinking if it would be useful somehow. – Vojtěch Melda Meluzín Dec 22 '18 at 19:14

That's an unusual setup. I also own a X299 mobo :-) For usefulness, I would prefer data security over the possible speed of a RAID-0, unless you have special purposes. – zx485 Dec 22 '18 at 19:18
You are probably right :) – Vojtěch Melda Meluzín Dec 22 '18 at 19:30
