Hi to all,
If you remember, a couple of years ago, I started on this forum the discussion about read speed drops on the 840 EVO.
Now I own (also) a 850 PRO 1TB drive and I noticed a slow-down on old files like with the 840 EVO. The 850 PRO is installed in a PC which is 24/7 online.
Here is a scan of my actual drive:
And this is the scan after a run with Diskfresh:
"Old" files are about 2-3 months old, I didn't have the time to check that carefully.
So... Even with the 3D V-NAND we have the same problem as 840EVO but to an important less extent. Before the firmware fix, the old files in the 840 EVO dropped to 60MB/sec, in the 850 PRO they go just below 190MB/sec instead of a full speed of about 490MB/sec on my PC.
But the problem is still the same, and for a PRO drive I think it's not good at all.
What do you think? Try to scan your 850 PRO drives (with at least 1-2 months old data) and post here the results!
PS: my old 840 EVO 1TB drive with the firmware fix is running fine, no more slowdowns in the same rig... And that's better than this 850 PRO
