I've bought 4x Ssds of different manufacturers, at different times of different models.
1 was Doa.
1 broke down after 4 months, and machine had to be reinstalled.
2 of the same batch/model bought at the same time died within 2 days of eachother, and I discovered how bad windows 7 backup/restore is (useless over a network).
All units broke down without warning,literally working fine before shutdown, and then failing to be detected as drives at next boot.
The technology has inherent flaws.
It'll be hybrids for me, from now on. SSDs are suitable for caching.
