Wait, why are you using Windows 8.1? tongue.gif

I am on 8.1 and have never had an issue with rapid or magician. Can't say for sure what his problem is but it maybe an oversimplification to think it is 8.1.
Then again windows being windows does some wild and wacky stuff, lol.

When I first installed Windows in July

Earlier this month:



Your issue is definitely not performance degradation, that's huge drops. Try to force trim if its possible or Raid, or press log off and let the pc idle for like 1 hour, then re-bench, if that doesn't help try with other drivers and before you re bench, perform the same idle log off 1 hour, and turn off everything from background before you do.

Apologies for the extended delay, I decided to wait until everyone opened their Christmas presents and set them up before updating again. Quite a bit to go through so it'll be updated either tonight or tomorrow. Hope everyone has a fast, reliable new year. tongue.gif

When I first installed Windows in July

Earlier this month:



One thing that caught my attention is you've gone from 11% used space, to 75% used space. That is when things start to slow down. This is also why SSD users that maintain a high amount of free space don't see write speed reductions in benchmarks.

Your read speeds are virtually untouched, and write speed is what always suffers as free space is reduced. The 4K QD32 write speed is not an issue, that only happens in benchmarks, not on PCs. The single file, QD=1 4K write speed was not hit much. The 512K write performance did take a noise dive there.

Consider what the recommended user Over Provisioning amount is, usually from 10% to 25%. (Enterprise SSDs have 50% factory OP.) If we choose 25% OP, your RAID volume is full now. Choose 10%, and you have 15% free space left.

Ever run a Windows disk Cleanup, or in CCleaner? Just to free up some space if possible.

IMO, running more benchmarks to check the array is just causing more "damage". If the performance has not suffered in actual usage, then you're fine, but are really at the edge of filling the drive a bit to much. While it won't fail, it's not a benchmark record breaker anymore, even when using IRST 11.2.

You did say you verified TRIM was working? How did you do that?

Hope everyone has a fast, reliable and 50 cents per GB new year wink.gif
Update:When i think ,40 cents sounds manageable with TLC.

Thanks for the information. My space usage mostly due to the large amount of games I have installed (my steam folder alone is 160 GB). I ran the benchmarks last month because I was curious if there was any performance drop, not to check health of the array. SSDs are something that I've never really looked into that much so I wasn't sure if it was normal to see a loss like that. But, since it appears to be normal, I don't think I will do anything about it since, like I said, I haven't seen any performance loss other than the benchmarks.

I checked to see if TRIM was enabled by "fsutil behavior query disabledeletenotify." Then, I checked to see if it was actually working using the HEX Editor method.
