Oh well looks like the problem is back! Or as never fixed. Will check my drive tonight.

Thanks for the info.

I have now secure erased and restored twice since the firmware update, My drive is losing performance fast now.

How do I go about getting this sorted ? I don't think my Evo performs as described. If I send it back to OCUK, will they just replace it, or will they need to test it (that could take about 6 weeks before they prove it is faulty) ?
 
Samsung could have a big problem.

There is no doubt that my Evo is slowing down. Real world performance hasn't suffered as badly as the benchmarks suggest (there is a subtle loss of speed, but it isn't much).

I swore by these EVO SSDs. They have good specs and were one of the cheapest SSDs on the market. Perhaps we are now finding out why. At least Samsung are a massive company, and will surely make sure that this issue is resolved, one way or another.

Maybe they'll just sweep the problem under the carpet (like they seem to have done with the 840 non-Evo). If they do, I'll continue to buy Crucial SSDs for my customers.
 
I carried out a firmware update/performance restoration on a 120GB EVO yesterday. The benchmark chart was a lot better, but far from "smooth".
 
Well I am pleased to see that mine is still ok.

Mine still seems to be ok - I don't think the firmware update + performance restoration alone is enough - cells that were badly out of whack seemed to continue to degrade again until I cloned it, secure erased the drive and wrote the data back again.

Mine's been secure erased twice (maybe three times) since the restoration and the image/restore has been done with Easeus Todo. I checked disk alignment was correct with Mini Partition Tool. Starts off with good performance, then starts to degrade after about a month. PC is used virtually every day.
 
I only ran the restoration software/firmware update, I didn't do a secure erase.

8MB block size

This was after the update

and now just over 3 months later

I installed a 250gb Evo in my rig just before Christmas.

Do I need to be concerned? And what do I check?

Download and install HDTunePro5.5 (trial version) here......

http://www.hdtune.com/download.html

Run it. Goto File>Options>Benchmark and set "Block size" to 8MB.

Start the test and wait a couple of minutes for it to complete (don't do anything with your PC while it's running).

You should end up with a reasonably straight line (it will be a bit "bumpy") around the 500MB/s mark, assuming you`ve got the SSD connected to a SATA III port.

Post a screenshot if you can.
 
You should also check your firmware version.

It should be EXT0CB6Q. If it isn't, you'll almost certainly see low read speeds. If it is, and you still have low read speeds, you may well have a "faulty" SSD.

Ran the performance restoration package a few months ago, tested at the time and was fine.

Snapshot is of test run today. Not looking good.
 
Just tested the 120GB I have in my work rig

So, that's 3 EVO's in 3 different machines I own where performance has dropped back off a few months after the restoration fix.

Bailey/OCUK - Are you re-liaising back with Samsung about this?
