I have two 840 EVO's and can't say I've ever had any performance issues... Yet!? I've always kept them on the latest firmware as I've heard they've had problems with theirs.
I haven't used one on Linux though.
If this is a widespread problem then Samsung really needs to sort it out once and for all. They're great performers for their cheap price, but nobody will buy them if they're always worried their data will be at risk.
And I was about to buy one. I was listing the size of the various folders on C:, to see what could be moved to D: so as to make C: fit into a 512 GB SSD. And now this bit about data on SSD that live a precarious live as now-you-see-it-now-you-don't. Sux.
I cant imagine using SSD drives which will fail horribly (You won't even know, it could be even the best ones out there). So yeah, whatever people says about its performance, I am still going for a mechanical one.
I just lost a 120GB OCZ Vector after about 20 months of usage. No idea what caused it but the thing is dead. That is the second SSD that died on me since 2008. Since all my PCs run on SSDs, that's not too bad.
Michael, I have no clue why it died. A couple of days ago it just dropped dead. I have submitted a claim to OCZ because that Vector has a 5 year warranty. So there are chances I will get my money back.
In the meantime I installed a new Kingston SSD (that was the cheapest here in Germany). I checked the Vector with a few enclosures but it is definitely dead. I suspect the internal controller but I guess we will probably never know for certain.
And you are right. I had an image from a couple of days ago. So getting back up was no problem.
ALL drives, SSD or HDD, will eventually fail so there is no point in shooting yourself in the foot. There are good, not so good, and bad brands with both. Keep in mind, the only reports of the data loss problem with the Sammy 850s is from a commercial server using Linux. Windows users have nothing to worry about and I have yet to hear of enthusiasts using Linux having the problem.
Some people had trouble with slowing in the 840 EVOs but many more did not. I'm running two of them and I haven't had a problem (yet). There are firmware updates available but I'm a firm believer in if it ain't broke, don't fix it.
I have had 3 or 4 Seagate 1TB /2TB drives fail over the last few years. All went within a few hours and Hard Disk Sentinel - HDD health and temperature monitoring warned me before the drives became unreadable. All you can do is make sure you have a back up. Drives fail SSD or Spinning rust. I had issues with a Samsung SSD twice I got a dud. One just kept disappearing from the system causing BSOD, the other one became read only after a few days. Could have been the motherboard as I RMA and got a refund and eventually gave away the board. I bought 3 x 256 Gb Toshiba, 1 x 256GB Crucial and 5 x Kingston 120GB and never had an issue. The Kingston drives are not as fast but in their PC applications (Notebook, 2 x Media PC and 2 of my desktop PC) I use for various tasks. The Toshiba drives are in my main PC's dual booting 7 & 8.1 and one Toshiba in Tammy's fast PC.
The original blog post has been updated and the problem is not being caused by what they thought it was. Samsung is investigating the problem but it appears to be unique. Looks like this may be another false alarm, like the other one about SSDs losing data over time.
