A few things to consider.

Firmware quality/stability is more important than any specs in data sheets from the user experience point of view and the most well regarded vendors for SSD data integrity are Intel and Samsung. They have excellent toolkits for data migration and SSD monitoring and maintenance.

If your files tend to be incompressible (photos, movies, zip files etc), stay away from Sandforce controllers which do poorly with these. Intel's consumer line unfortunately uses these.

If you want to do your own detailed research, check out websites like anandtech, storagereview and hardocp.

Cheers.
