Windows 7: When SSDs are not that solid

When SSDs are not that solid

Appears to be happening to a particular brand.

"As it turned out, the lost data was always 512 bytes, which is one block on the drive."

"The system was issuing a TRIM to erase empty blocks, the command got misinterpreted by the drive and the controller erased blocks it was not supposed to. Therefore our files ended up with 512 bytes of zeroes, files smaller than 512 bytes were completely zeroed."

From what I've been reading elsewhere, it's happened only on servers and Linux systems (so far).

Would this be fixable with a firmware update? I guess I would have lost something by this time? A little bit more than 2 months with this 850 Pro 512GB. Anyway to check in Windows?

Over on Overclock Forums, they've been reporting that this hasn't happened on any Windows machines, just servers using Linux. There was an update a while back that was bricking the 850 Pros but Samsung pulled that sucker right away (another reason to wait before applying any updates to anything). I don't think it was a recent update and I don't know if one would fix this or not. The Sammies that have had this problem were in a commercial server using Linux, something the Sammies were never designed for; they are a consumer drive.

Are there industry SSDs? I don't understand the firmware/OS interactions. I had assumed there weren't any - probably a wrong assumption. I was going to put linux on a spare 840 EVO but may rethink.

Yes, they are called Enterprise SSDs and many of them cost a pretty penny.

You might hold off on Linux on an EVO although I believe it's only the 850s that are having this problem. Of course, the 840 EVOs had their own problem.

Here is a link to one of the threads about this over at Overclock.net.

Whoops, found another link. This one sounds more dire, especially since it seems Samsiung isn't the only one with the problem.

"Come in Spinner" - an Australian in joke.

"Of course, the 840 EVOs had their own problem." Is this the type of issue:
Second patch for ongoing 840 EVO SSD performance issues being prepped by Samsung | ExtremeTech

Samsung's not looking good at this rate. What's your favorite SSD???

This Crucial owner says Intel. Used to own one. The connectors failed, and I replaced it with a Crucial, saving a fast 10 or 15 dollars. Probably not one of my best moves.

Yep.

Uhhh...Samsung? All seriousness aside, I have a 128GB Samsung 840 Pro that has been running pretty much 24/7 for the past 28 months without a hitch and two 840EVOs in two of my notebooks. I haven't had any problems with the EVOs, either (but, then again, they get really light usage). The only reason I don't have an 850 is they weren't out yet when I bought my last EVO.
