Cons: For non-windows system (opensolaris and freeBSD for me, though reportedly linux too) this drive does NOT present itself natively as a 4kb sector drive. WD has put into the firmware an emulation layer that causes the drive to be seen as a 512 sectored size in unix. Because of this performance is seriously hindered. You can solve this problem by manually aligning the partitions, but that's just extra unnecessary work.
