    Posted: 01 Nov 2019 at 3:50pm
i'm tring to make a raid 0 with 3 SSD samsung 860 EVO that tested 1 by one and are capable of something like 500 MB/s R/W sequential.
When i make the array, doesn't matter the stripe size, i can reach only 750 MB/s.
I expected to reach the DMI interface cap that should be around 1.6GB/s, at least in sequential read / write
Looks like there is a bottleneck somewhere but i can't find where.

I've already:
- selected SSD on bios sata devices.
- installed latest intel RST Versione driver 07/08/2019

Can someone help please?

p.s. sorry for my bad english
