Lady Fitzgerald Is anyone taking care of this thread? I need to have six 4TB 860 Pros, three 2TB 850 EVOs, and four 2TB 860 EVOs added to my stable.

ozlay I wish they sold the 2tb msata in the T5 separately. Not that it is hard to take it out of the T5.

Ceadderman I would test for it on my 860 EVOs but neither of them have any "old" files on them. They've been running since the end of March. Apologies.

Would like my 500gb and 1Tb drives added to the list please. I would post proof of the 1Tb but the screenshot seems to have vanished.

Yes, but consider how the 850 EVO readspeed/file-age graph looks and check how a similar test ran on a 6 year old Intel 520 series SSD looks like - which is much smoother:




This same drive is 81% full:



So by asking buyers to test I was actually curious whether it looks more like this or like my 850 EVO which I posted above.

The severe slowdown problem was limited to the earlier 840 EVOs. The later 840 EVOs had the problem corrected. Samsung also issued a patch for the earlier 840 EVOs that sometimes corrected the problem. The 850 and 860 EVOs do not have that problem.

Hello!

Check my older post from here: https://www.overclock.net/forum/355-...l#post25005377

And also a fresh test that I ran - it seems that the issue still persists somewhat, although in truth it doesn't make itself noticed in day to day use:


For those unfamiliar with the tool in use - SSD Read Speed Tester 2.04 - it was specifically built for testing these sort of issue - read the topic I linked to above for more details and evolution of the story/problem. You can get the program from here: https://www.overclock.net/forum/355-...l#post22842513

For whomever inherits this club. I would do it but I simply don't have enough time due to my 3yr old and summer coming up will be working maximum hours.
