271.9788 / 256 = 1.0624172

(1024/1000)^1 = 1.024000
(1024/1000)^2 = 1.048576
(1024/1000)^3 = 1.073742
(1024/1000)^4 = 1.099512

So the units of the SMART attribute are hard to explain. They are closest to GiB, but still about 1% off from GiB.

I guess there is a bug in either the Sandforce firmware or Anvil's app.
Yeah, A = 272GB or 253.3GiB for an increase of 256 in the SMART attribute. Each 64 increase was very consistently 63.2-63.4GiB too. Until more data says otherwise, I'm going to take SMART attribute readings for SF-1200 to equal GiB.

Just ran 135.95GiB of writes to my X25-M 80GB G1 and it showed up as 136.72GB in SMART (and damn my G1 is slow and stuttery with this...35MB/s and a stall once every 5-10 seconds). It would be good if someone could double-check this with more writes--my G1 just doesn't want to take part in the party.

Started it back up on my Vertex 2s with Task Manager running, will let it run for awhile and see what differences there are, if any.
