Dynamic disks

[Glasgow3]

Hey, a short question about dynamic disks: 

 

I recently changed my mobo, and acquired a new 1TB nvme SSD that I use for my system. I happen to have 2 old SSDs I used before, one 128GB, the other 512GB. I wanted to use them as one dynamic disk (some kind of  "in windows" JBOD in my understanding) to make data management easier. I use windows 10.

Strangely, I made tests and the throughput towards this ~ 600GB "dynamic" drive is much lower than towards one of these disks in a simple partition mode. (200MB/s instead of 450MB/s)

I read that usually, dynamic drives have faster writing speeds, because data is split, and parts of it can be written on both drives at the same time.

Is this something known? Is there an easier or better solution than dynamic drives? Thanks ! 

 

Post scriptum : Everything is backed on a 9TB NAS

Doh finally found it. "Storage spaces" is the response I needed. This post should be deleted I think, sorry !
