Hi all, I hope that I posted this in the right category.
My goal is to get the setup below to run RAID 1 and benchmark within the specs of a single drive in AHCI. I read RAID 1 theoretically should at least read and write near the speeds of a single drive. I didn’t expect the performance loss in the benchmarks below. I’m hoping someone has a suggestion as to what I’ve may have done wrong or if there may be a limitation in my setup. The drives are on the mobo.
CPU: AMD Threadripper 2950X
RAM: G.Skill F4-3200C14-16GVK DDR4 x 4 - 64GB @ 2933MHz
Mobo: MSI - MEG X399 Creation
GPU: Radeon R7 370
OS: Win 10 Pro
NVMe SSD: XPG SX8200 Pro 1TB x 2
-CrystalDiskMark v 5.5
-AS SSD v 1.9.5986.35387
-ATTO v 3.05
A single drive in AHCI here.
The drives are assigned to a RAID 1 array here.
As you can tell, the RAID 1 setup is not performing as well as a single drive in AHCI.
Any help is appreciated.
