I think the Samsung uses 8K pages (based on some info on a far flung part of the Samsung website that I can't seem to find at the moment), but I'm not positive. 20 blocks is nothing... (it's still at 99/0/20). I was just expecting some more, especially if PE count is accurate.

Also, if you look at the smart data for my 830, notice that Program Fail = 0, Erase Fail = 10, Runtime Fails = 10 blocks, but the total number of reallocated blocks is 20. This could mean that the attributes are mislabeled, but I don't think so. Replaced blocks just = 2x Runtime fails.
