[Statistics] Reliability of various consumer SSD models
Data source: Customer reviews at www.newegg.com
Methodology: Read through all reviews with only 3 eggs or less and identify deaths / problems through review description. (When a customer has met more than 1 dead SSD, the death count is only 1, and the review count is also only 1.)

(*) Problems include BSOD, freezing / stuttering issues etc.
(**) Assume the failures are evenly distributed over the power-on hours, which is what HDD vendors quote for MTBF.
I don't want to include the OCZ models, as the effort required to read through the negative reviews would be unacceptable! :D
Note that the statistics for G2 is incomplete - I am unable to obtain the links for all deactivated models (if you have a collection of them please let me know!)
The numbers of M4 stratified by page size don't add up exactly for the previous stats, probably because newegg activated / deactivated some products, or there were minor counting errors.
I'm inclined to believe that the 0302 FW of the 320 Series is prone to be bricked into 8MB, and the 8kb page sized models of the Crucial M4 (i.e. 256GB and 512GB) are less reliable.
My 2 cents.
