This will not affect your laptop, all of the models affected by this are enterprise SAS SSDs. Of course your SSD might have some other firmware bug that would eat your data, all you can do is search for the model number and see if the manufacturer has issued any notices/firmware updates.

  How likely is it that they're using an enterprise SAS SSD in their laptop?

  I've been searching "40000 hour SSD" since the HN downtime. There's a lot of bug reports besides this one and I'm fairly confident it only affects enterprise too.

  > Without knowing parts of a codebase are shared between SanDisk devices, it is hard to say that enterprise SAS devices have absolutely no code shared with consumer devices. Even if the code containing this bug was shared between consumer and enterprise drives, it's not reasonable to assume that it would take SanDisk multiple years to check whether their consumer drives are also affected. The lack of a follow-up report from SanDisk is good evidence that their other products are not affected.

    Yeah, I agree it is very unlikely to affect someone’s laptop. However I dislike a black and white “This will not” absolute fact statement: even if based on reasonable assumptions which is what appears to be the case versus detailed knowledge. Most laptops don’t run their SSDs 24/7, and unless a manufacturer’s error affects a lot of consumers, we often don’t find out the cause of consumer equipment errors in my experience. If the OP has a laptop older than 2020, with an SSD with a crucial chipset (especially if SATA), and they leave it on most of the time, then maybe check SMART hours.

There was at least one consumer SSD with a similar failure mode, the Crucial M4 SATA drive, unless you updated the firmware it would crash after 5200 cumulative power on hours. That drive launched in 2011 though so there probably aren't that many still in active use which still haven't reached ~7 months of uptime.

  Yes. This one: https://www.reddit.com/r/buildapc/comments/1z2rm5/crucial_m4_5000_hour_bug/ https://www.reddit.com/r/buildapc/comments/1z2rm5/crucial_m4... That problem became known a decade ago, so it's somewhat surprising to see such a similar bug now. This new one is worse because the drive cannot be used after reaching the magic number of hours. In the Crucial M4 case the firmware could be updated even after the bug struck.
