Hello, 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 17.7.0.1006 07/08/2019 Can someone help please? p.s. sorry for my bad english
