Hmmmm.....I am growing old disgracefully and I sometimes forget things but I seem to recall that early on there were some issues. Crucial issued a firmware update which fixed the issues and actually improved performance. They've been fine since then.
When I make suggestions for several brands I usually recommend Samsung first and Crucial second.
I maintain the ssd database listed in the sticky at the very top of this ssd section. Here is the link:http://www.johnnylucky.org/data-storage/ssd-database.html
Scroll down to the brands and models you are interested in and follow the links to the technical reviews.
