840 Evo SSD slowdown - heads up -

[ryanbatc]

Wasn't sure where to post this but Samsung is working on a new firmware update for a serious design flaw in their 840 evo's. Mine is affected... they claim only a small amount of people have the drive that has these issues...

Anyway old data (older than 1 month) will be read at crazy slow rates (typical read is 450 mb/s, old data is only read at around 40-80 mb/s)

I have this SSD too, but fortunately no any problems (1,5 year).

You may though... They're saying the programs that report speed write new temp files then read those.

its the older files you need to check.

Either way I hope yours isn't affected.

@TY ryanbatc!

We never know when such messages come in handy. I checked Today my Evo 840 and here a results:

Old files (ups):



New files (is ok here):



Not good I think. I havent here FSX, just P3Dv2 (it still waiting for better times) and some of meshes for both tittles so I didnt noticed any problems.
Simply I dont fly in P3D since more than half a year.

Here is a tool to repair this (I do backup now this SSD):

Sweet... I'm sure a ton of their drives had this issue.
