Recently, I bought a pair of those new Western Digital Caviar Green drives. These new drives represent a transitional point from 512-byte sectors to 4096-byte sectors. A number of articles have been published recently about this, explaining the benefits and some of the challenges that we'll be facing during this transition. Reportedly, Linux should unaffected by some of the pitfalls of this transition, but my own experimentation has shown that Linux is just as vulnerable to the potential performance impact as Windows XP. Despite this issue being known about for a long time, basic Linux tools for partitioning and formatting drives have not caught up.

I know it is not supposed to be an advanced format drive, but running the code at the and of the article indeed shows performance differences with alignment other than 0 and 8. (I ran it on a partition starting at sector 64)

Also the disk freezes a lot when doing io.

I am sending it back.
