RAID 0 issues

Hi all,

Long time since I have posted here. I recently upgraded my laptop and pretty much maxed out the spec (check sig). I'm having issues with my RAID volume, which is also my boot volume. The speed seems to throttle. After a reboot, I can run a benchmark and can immediately see great sequential read and write speeds in the range of 1GB/s but I can immediately see the speeds start to deteriorate. As soon as I run the benchmark again, the speeds will dip to below 500MB/s and never increase back the the speeds I should be seeing. I'm wondering whether I'm doing something wrong. I installed the Intel Management Engine drivers and the Rapid Storage drivers but there was no change. I removed them for now but open to any advice.

This is a clean install of windows 10 and I have not done anything in terms of OS storage tweaks aside from seeing if write-cache buffer flushing affects anything (it didn't). Are there any specific settings I perhaps should have used when settings up the RAID volume?

I remember back in the Alienware days, the heat of the chipset affected the SATA speed, I wonder if that is a factor.

This isn't a big issue because I'm sure even if the speed was consistent, I would not notice the difference but it would be nice if it worked properly. I recently ran a Firestrike benchmark and was pleasantly impressed at a 14,000+ score and with a 20,000 GPU score and 11,000+ physics score. Would be nice to have scorching fast SSD speeds too

 

See if hardware Monitor picks up your chipset temperature

 

Have you tried Samsung Magician software for the drives? Might be more useful since you have Evos, than RST.

 

You can try but intel raid usually masks the devices to software on the OS.
