Well if you think about most of us experienced the issue...and some of us it went a way... *knock on wood* ... hope it never comes back...
I think its more like a breakin period for the SW...I know that sounds wierd...but this issue seems to manifest itself when the SW's were just purchased brand new...
Im thinking is that the Seagate Momentous XT's has a lag between the HDD and the SSD the first few weeks you use it and just kinda compensates its self...
