SSD Write Endurance 25nm Vs 34nm

It is only one factor. The Samsung 840, at it's current price, is just not competitive. There is no compelling reason to buy a TLC based drive for the same price as a MLC based drive.

As I see it, durability stops becoming a factor after a certain threshold. The type of workload will determine what the threshold is, but for your typical consumer workload whether one drive achieves 400TB or 4PB seems pretty immaterial and should have no effect on your purchasing decision.

If TLC has issues besides just endurance - like retention - then that would be valid reason to favour one over the other.

Btw, I should thank you for testing this drive and providing this very useful information, as it was the reason I actually bought an 840!
