Does this issue affect all 840 SSDs inevitably or is it a hit or miss thing? I have 2-3 of these SSDs and I have not really recognized any such problems so far.

Its painless. LOL

Correct me if I’m wrong, but I thought the issue mainly was for people who had these drives in systems that were powered off for weeks/months at a time and then tried to use them again and encountered this issue.

Not necessarily. All that’s required is writing a file, never opening it/updating it for a long time (so you never refresh the stored charge), and eventually the stored charge might droop just enough that it triggers the aggressive read retry bug. It doesn’t drop so much that the data is lost, but the drive’s firmware has to be sure it isn’t getting bad data.

But turning off a system and not using the drive for a while (while it has data stored on it) follows the general formula to run across this issue.

This issue seems to be a bit hit or miss.
It doesn’t affect all drives. I have 4 840 EVO’s here, 2x SATA 2x mSATA, and can’t replicate the issue on any of them.

A new firmware should be able to fix this quite easily, now that Samsung know what causes the slowdown to occur.

Maybe it’s because you know how to treat your hardware, whereas others don’t. You are quite the storage expert, after all. :wink:

(Or maybe your usage patterns & other environmental factors just don’t make the drive fall into its low-performance state, I dunno.)

No bugs in the new version I hope :stuck_out_tongue:
