Hardware failure
Added 2019-07-30 12:26:34 +0000 UTCMy 250GB Intel SSD 510 bit the dust today when I logged on to my desktop to check my email.
This shouldn't really be a surprise, since I (obliviously) exceeded the MTBF of the SSD by 2 years. Intel doesn't provide a TBW rating for this drive on their specification sheet for it. However, based on similar drives of the time, the rating would likely be around 30 TBW, and I definitely exceeded that over 9 years of use as well.
This throws a bit of a wrench into the works. I didn't lose any data, as everything I was working on was backed up, but I will have to work from my laptop for the time being.
As a replacement, I ordered a Samsung MZ-V7S1T0B/AM. Hopefully it will be here soon.
