I'd still replace that SSD if I were you. If it failed once already, it could easily fail again. No sense taking unnecessary chances. Hope your "bake-offs" continue to work for you, too! Great story. I remember the days when parking a conventional hard disk in the freezer was a recommended technique to get one working again after failure long enough to recover the contents.

Totally agree!
When an HDD is starting to die, you usually get warning signs, and might be able to save some data.
When an SSD dies, it just stops.
You have just gotten a sign it is failing(with luck).
First you need to get any data you need copied somewhere else right now, and then create a system image if you haven't already, that you can later just reimage onto a new disk(yes simple as that).
Why Test SSD NAND Write Endurance?When a SSD fails:
A SSD is considered failed when static data is corrupted, the SSD unit stops working or if the SSD performance is permanently degraded to below a usable level.
If SSD performance is seriously reduced we will let it recover during a minimum 6 hours of idle time. If performance issues remain we'll try to contact the manufacturer.
Read all 4 pages starting here, please: The SSD Endurance Experiment: They're all dead - The Tech Report - Page 1The Corsair, Intel, and Kingston SSDs all issued SMART warnings before their deaths, giving users plenty of time to preserve their data. The HyperX's warnings ended up being particularly premature, but that's better than no warning at all. Samsung's own software pronounced the 840 Series and 840 Pro to be in good health before their respective deaths. Worryingly, the 840 Series' uncorrectable errors didn't change that cheery assessment.
If you write a lot of data, keep an eye out for warning messages, because SSDs don't always fail gracefully. Among the ones we tested, only the Intel 335 Series and first HyperX remained accessible at the end. Even those bricked themselves after a reboot. The others were immediately unresponsive, possibly because they were overwhelmed by incoming writes before attempted resuscitation.
Also, watch for bursts of reallocated sectors. The steady burn rates of the 840 Series and 840 Pro show that SSDs can live long and productive lives even as they sustain mounting flash failures. However, sudden massacres that deviate from the drive's established pattern may hint at impending death, as they did for the Neutron GTX and the first HyperX.
