Can't Get Full Performance of Triple-SSD RAID-0 Array #8

Closed FluorescentGreen5 closed 2 years ago

FluorescentGreen5 commented 3 years ago

While Dynamic Disks lets me achieve around 1.2 GB/s on 3 SSDs running in RAID-0, WinMD can only achieve 825 MB/s, akin to only 2 SSDs in RAID-0. CPU usage is around 4% during sequential tests in CrystalDiskMark and each SSD only gets to about 66% usage in Task Manager during these tests. The SSDs only reach 100% during random access tests.

CPU: AMD Ryzen 5 3600 RAM: 2x8GB DDR4-3200 SSDs: 480 GB Intel DC S3610

UPDATE: It seems like the MadMax plotter is able to break 1 GB/s when plotting to the array.

Interesting. I can't think off the top of my head why this would be - I'll look into it when I get the chance...

@maharmstone will you ever update this very promising project? At least degraded mount and resync

maharmstone commented 3 years ago

Plan to, just been busy with other things!

FluorescentGreen5 commented 2 years ago

I think I found the issue: CrystalDiskMark sometimes only uses 1 thread for both it's sequential tests. I will try manually configuring it to use all 12 threads when I get the time.

Yep, that seems to have done the trick.
