3x NVMe raid issue

[seboldsg]

Hi, I've got 3x 1TB samsung 960 evo. I have installed windows on 1 (C:/) and made a RAID0 (for my current video editing projects) with other 2 (D:/), on CrystalDiskMark Seq Q32T1 on single drive (C:/) I have 3334MB/s READ and 1925MB/s WRITE but on RAID0 (D:/) I have 3465MB/s READ and 3802MB/s WRITE. I'm happy with WRITE speed but shouldn't READ be around 6000MB/s ???

What are your full system specs and how are the drives connected?

In theory, you're right (although RAID0 does not = 2x speed by definition)..... but there are variables. CPU lanes vs Chipset etc.

I don't want exactly 2x write speed, just want to fix it and will be happy with 1.5x + speeds for read.
