I've been using my Samsung SSD 850 EVO (250GB) now for over 2 years (Win 7 pro, 64 Bit) and have no problems at all. I've been using their Magician "Rapid Mode" up until a couple of days ago and I experimented by disabling it. I haven't seen any difference in speed or anything at all whatsoever. Opening programs, rendering graphics etc etc all seem exactly the same.

Anyone else ever tried (or untried) Rapid Mode on their Samsung SSD's?

I also allocated 10% of my disk space to over provisioning when I installed the drive. I wonder if that was really necessary. I'm a little unclear as to what it actually does. Google links explain it but not clearly. I'm not in any need for more disk space, using only about 45-50 Gigs at any time but still I hate wasting space.
