Assistance - Calling all Samsung EVO owners

I don't mind the fix being a bit "late" if it means that Samsung are making sure it really does fix the issue.

I think they know that they must get it right this time, otherwise they are likely to be getting a fair few 840 EVOs being sent back to them for repair.

It would be a different story if 840 EVOs were approaching the end of their 3 year warranty. I think we still have over a year to go, so plenty of time to return them to Samsung if they can't get them to work as per specification.

must agree there to be honest, would rather wait a bit longer for the fix and it work first time than be in the same boat again 3 months down the line because they rushed the last fix and it didn't solve the issue fully
 
yeh it has to be a manufacturing thing right?
i duno i feel im not smart enough to understand it fully haha
i wonder the % of people affected tho
if it was a low % would make more sense to replace the drives? so my guess is its not lol

I hope their 'fix' isn't the inclusion of the 'advanced' tab that lets you run the performance restoration tool. If we have to maunally do this every few weeks, then it's not a real fix.

Doesn't sound like a "manual" fix, but for some users it might be (if they leave their SSDs powered down for extended periods of time).

It may well be that the background refresh does reduce the life of the SSD, but I'm not too bothered about that, as I still expect mine to last the 5+ years I'd expect it to before I upgrade.

If the firmware update maintains performance, and doesn't require any user intervention, then I think Samsung will "get away with it". Just.

Any sign of performance issues after the update, I think it's time to say "please replace my 840 EVO".

I'll be unhappy if their solution is to run a program periodically. The fix should be integrated into the firmware and the user should be none the wiser or have to worry about periodic refreshes.
 
So the fix it's a background Disk Fresh task. Didn't see that coming!

I'll be ditching my 840 EVO asap, and I'll be 100% Samsung free, already having replaced my Samsung TV and Phone last year.
 
so there fix is to get the firmware to do a periodic refresh every so often when the SSD is powered on.

if the ssd isn't on long enough for this to complete they have give you the option to do it in the software (4.6)?
 
You guys realise that all SSDs rewrite their data periodically anyway right? So this firmware change isn't necessarily adding something unusual (though the manual 'fix' option is doing a significant chunk of writes - not enough to drop it anywhere near below their targeted lifespan but still a big chunk if disk is nearly full)

The refresh routine appears to run in the background, when the drive is idle, so it shouldn't affect performance in normal scenarios. Refreshing old data may consume some of the NAND's limited endurance, though. We've asked Samsung to clarify how frequently data needs to be refreshed and how this affects write amplification.

Since old data can only be refreshed while the drive is on, those who leave the EVO unpowered for extended periods will have to rely on the Magician software's optimization mechanism if they want to restore full performance quickly. It's unclear how long the EVO will take to optimize itself after extended downtime.

Reading this bit from the techreport article above, it doesn't sound like a proper fix to me.

Going to see if I can return mine.

The firmware update will allow the drive itself to periodically refresh "old" data. Assuming a 1000 write cycle, even if it did it once per week (which would be pretty aggressive), that is only 5% of the write cycles available, so after 5 years it has still only used 25%. If they do it every fortnight, that is 12.5% after 5 years. Not that big of a deal, really.

I don't think it's that big of a deal. Yes, it's not IDEAL, and given the choice right now, I definitely wouldn't buy another TLC drive. But if it fixes the problem, with relatively minimal impact to the lifetime of the drive, then it's not the end of the world.
