I may be wrong..
But I'd bet a few dollars or pounds that they are Intel drives. We had a number of Intel drives that never got firmware updates fail (in high-end workstations) within weeks of each other a few years back. The ones that did get updated kept going. They were quietly replaced by the PC manufacturer, but it soured me on Intel SSDs. And again, I could be wrong, but I wouldn't be surprised in the least if lessons weren't learned by Intel. Of course we had a smaller rash of Samsung failures around that period too. Really, the only ones I have no complaints about were made by Crucial/Micron. I'm not a marketing shill, I swear, but Crucial's stuff has had a much lower failure rate for us than anyone else. And a few that were unresponsive were recovered by whatever internal failsafe that is built in, simply by hooking them to power and letting them sit for a while.
If someone knows the manufacturer of these drives for sure (or if I'm just being thick and missed it somehow in the article), I'd be curious to know.
