Yeah I got one of each as well, I didnt realize they were different processes/batches other than a small firmware update I figured...good to know. They are great lil' devices in my book...I 'almost' like them more than my obsession w/ s3700's...ALMOST. :-DIF these drives turn out to be the Hitachis that we've been buying lately
I got one from the 2nd batch of those 100GB drives and apparently wound up with: HUSSL4010BSS600. It looks like A was their 34nm process while B is the new 25nm SLC.
The 200GB is an A thou in which I bought a few days later.
Some good info on these drives from SR here that detail some of the differences. Hitachi Ultrastar SSD400S.B Enterprise SSD Review | StorageReview.com - Storage Reviews
