Update on Samsung SSD 840/840 Pro Failuresby Anand Lal Shimpi on November 28, 2012 12:06 PM EST
In our review of Samsung's SSD 840 Pro I noted that my drive died shortly after I completed testing. Samsung sent me a replacement, which also stopped working (although it still pulled current) after a couple of days. Kristian's Samsung SSD 840 review sample shared a similar fate.
I spoke with Samsung about this problem a couple of weeks ago and was told that there was a bug in the pre-production firmware (version 2B0Q/5B0Q for 840 Pro/840) loaded on our drives. All retail samples should ship with a newer firmware revision (3B0Q/6B0Q) that have this bug fixed. To confirm what firmware revision is on your drive, look at the end of the hardware id string for the SSD in Device Manager.
Samsung sent me an 840 Pro with the updated firmware and so far I haven't had any issues. I'm trying to retrace my steps in bricking the drive and things are looking good thus far. As always, if things change I will update you all.
