The Corsair Force GS series is a brand new ssd that was released 3 weeks ago. It does not have an established track record. I always recommend waiting 6 months to see if any problems wrise.
The Samsung ssd's have a well established track record. Highly recommended.
I maintain the ssd database that is listed in the sticky at the very top of this forum section:http://www.johnnylucky.org/data-storage/ssd-database.html
