I'm suspecting that it isn't as reliable due to its use of a generic SandForce controller. Marvell controller-based SSDs have higher reliability at the expensive of some speed. A good example would be Crucial m4.
Is it a Sandforce drive or not? If it is you're most likely going to run into the same issues that plague most Sandforce drives - from Intel, Corsair, Patriot, and so on. If it's Marvell based you won't really need to worry.
