Info on Western Digital Special Edition drives?

[Digerati]

Just wondering if anyone knows if Western Digital Special edition drives, in particular the WD800JB come with Fluid Dynamic Bearing motors?

I just got rid of a Seagate Barracuda IV 80gb and replaced it with a WD800JB 80gb special edition drive. The WD has an 8mb cache, but it seems a bit louder. I'm not sure if it's just my mind playing tricks on me, cause it's not a huge difference. Just wondering if the WD drives have the FDB motors that might account for what i think is more idle noise (a high pitched whine).

The Seagates are more silent than the Westerns. I saw some disks from WD with FDB but they were hellishly expensive. And I thought they had that allready... Oh well.

If the disk has FDB it should be more quiet than a normal ball bearing drive. Seagate only uses FDB afaik.
