Got my 990 Pro 2TB to upgrade from a 970 Evo Plus which I’ve had for over a year. The 970 for ref was at 99% health still last week before I disconnected it to clone over from onto the 990 Pro.

The 990 was fine until the other day when I noticed the health reported as 99%, now today I’m seeing 98%, only written an additional few tens of GB to it since that time.

Edit* My drive had dropped to 94% health before I contacted Samsung RMA service.

Anyone else noticed this?..

That’s why one must back up everything.  It’s not a question if a SSD or HDD will fail, but when.

There is no direct indication that the drive is failing, per se, only that the counter that tracks TBW and reports the percentage of rated life that remains is badly broken. Could just be a misplaced decimal point in the algorithm somewhere, easily fixed with a firmware update.

It is disappointing that Samsung, instead of promising to fix the issue and make things right with their customers, pretends it’s fine and returns the drives to the owners. These “bury our heads in the sand and hope it blows over” responses from various manufacturers seldom go over well.

Why are any posts from other sites/forums (YouTube, Bleeping Computer..), are posted here ? Maybe to alter users to problems not posted here ?

References are commonly and usefully posted from external sources but questions from non-members here are largely irrelevant – fluff, filler. They’re not asking us for help and the subject would have little to no bearing especially when there is no cause or preventative/repair actions listed – in either of the Topics (I believe you missed the original, which should have been the first reference used by any news reporter).

Half a ‘story’ omitted could be taken as a deliberate measure to attempt to bias others against a product or company, try to reduce any possibility of such attitudes creeping in.

I took it as a heads-up that something was up with these drives. This was the first I heard of it, but if you read the links, it seems to be much more than a one-off thing. Guru3d’s article on the topic is the last item on the first page in DDG when I searched “Samsung 990 Pro.”

There’s not enough known here about the drive to make any sort of judgment call. It’s unlikely that the person posting comment in another forum is available for additional information.

Don’t borrow trouble.

..Hello everyone, we have received feedback from our technicians on this:

Samsung is currently reviewing customer inquiries about anomalies related to the SMART Percentage Used (on Samsung Magician) and/or Health Status (on Crystal Disk Info) of the Samsung SSD 990 PRO.

We were able to recreate the error under certain conditions of use.
