So, it appears, from the article at the bottom of this comment, that the "write limit per block issue" is no longer an issue. I'll search here and there to find a reason why they fail so easily (no, imported, "cheap," manufacturers won't count, as expensive manufacturers have the same problem). One thing I've considered is that many electronics purchased from circa 2005 have had issues with electrolytic capacitors, usually used in the power circuit of electronic devices. Chinese electrolytic capacitors used in manufacturing of consumer electronics during that period (~2005) have had a short MTF (MEAN TIME to FAILURE) (see Samsung LCD monitors, most have faulty power supply circuits due to these shoddy capacitors). Article is dated, but has some useful infromation: http://www.storagesearch.com/ssdmyths-endurance.html
