"After a reboot, the SSD disappeared completely from the Intel software. It was still detected by the storage driver, but only as an inaccessible, 0GB SATA device.
According to Intel, this end-of-life behavior generally matches what’s supposed to happen. The write errors suggest the 335 Series had entered read-only mode. When the power is cycled in this state, a sort of self-destruct mechanism is triggered, rendering the drive unresponsive."
The company that bought their SSD division (Solidigm) supports the Intel branded drives, and their utility had firmware updates ready to go for the ones I bought.
I'd probably buy a Solidigm if I needed a new drive and these firesale Intel drives are gone.
I used to run Intel (enterprise) SSDs in servers. I didn't run enough other SSDs to have a sense for whether the failure rate was abnormally high, but it was definitely not zero (it was significantly less than the enterprise hard drives we were running). And the failure mechanism was sudden disappearance from the bus.
My message to you is not to avoid Intel SSDs, just to make sure you have a backup in place, because when they fail, my experience is there's no warning, they just disappear. This seems to be the common failure mode for all/most SSDs, even though they're supposed to fail read-only. Hard drives usually give warnings as they fail, but not always enough warning to rescue data.
