I’ve got a 840 EVO 1TB that has the addressed performance issue. Right after I discovered a performance problem the first time, Samsung released the Performance restoration tool which I applied. Read performance then went up from 11-70 MB/s to ~520MB/s. But a little after, performance once again started to degrade, and now I’m getting reads of about 350 MB/s – getting a little worse for every week that passes by.

Interestingly enough, everyones discounting the 840EVO’s and clearing them out. Bad sign.

In reply to dzezik. I always use Raid 0 - who's stupid enough to use Raid 1 when you can just buy a separate slow disk backup system and use the cloud? Imagine paying a fortunate for performance disks and using them Raid 1 hahahahaha

Should be mighty durable, right ? Even though it has crappy 20nm MLC with only 1.5k p/e

In reply to agooddecision. > Micron won't say it publicly, but we know their 20nm MLC is 1500 p/e cycles, so 16nm is less than this number). No we don't know that.
