SSD Write Endurance 25nm Vs 34nm

[Christopher]

With respect to the CDM numbers, look at the past couple of posts with CDM shots. The first two were with 1000MB, 5 reps -- and the best numbers are being displayed. One of 5 would be much better, and the other 4 would range from low to super low. As far as the writes go, they look better than the reads, but it's not sustainable. Running the endurance loop, the beginning loop instant speeds start at 100 and drop into the 50MBs range.

Secondly, I SE'd the drive many times, in addition to multiple Magician performance optimization runs. Then, just grasping at straws, I tried one of the secure drive wipes in Acronis Drive Cleanser (the fast one that just writes zeros to every LBA). Sequential writes seemed to help at first, but didn't really do anything.

I tried running the drive with Intel RST and MSAHCI, and on two different systems.



I ran HDTune several different ways, but regardless of which benchmark I run, there is something wrong here.

I will let the drive idle the rest of the day, but I don't see why that would work but secure erasing doesn't.
