Hi All,
I havent really scratched around / troubleshooted this yet but i thought id post this here so long.
I have a asrock wrx80 creator v1 board + threadripper 5975 cpu, have 128gb ddr4/3200 ecc reg memory
I have 2 x 2tb seagate firecuda 530 in raid0 (on motherboard)
then I have 4 x 2tb seagate firecuda 530 in raid0 on a highpoint ssd7505 controller
As seen in screenshot attached I was able to hit almost 38gb/s in combined benchmark. this would be running crystaldisk at the same time benching both devices.
So yesterday I added the following disks to the system,
1 x 800gb intel optane p5800x
1 x 960gb intel optane 905p
So now i open 4 x crystaldisks and run the benchmark at the same time, I noticed some of the
disks showing degraded seq performance (e.g p5800x showing 4xxx mb/s instead of 7400mb/s…
basically add all the bench up and it seems there is some sort of 30gb/s bottleneck
Where before just the 2 x raid0 volumes would hit almost 38gb/s combined.
Before everyone goes all nuts on me about the bench, I know seq isnt the be all end all
heck i know crystaldisk isnt the “authority” on benchmarking either.
Removing the 2 x u.2 (intel optanes) doesnt change this situation either.
wondering if its not a windows update somewhere along the line that changes something,
I should really get on with installing linux on this rig.
Any ideas?
