FWIW, I have 2 WD10EARS drives, along with 3 WD10EADS drives, in a RAID5 
array.  I needed to fiddle with fdisk to get the partitions started on a 
4K boundary.  By default, fdisk wants to start a partition at sector 63, 
which is obviously not on a 4K boundary, and would cause performance 
degradation if left like that.

I haven't had any problems with the WD drives in my array.  Also, these 
drives have been fast enough for MythTV.  I sometimes record up to 4 HD 
shows at once, while watching from a frontend, while commflagging, and 
haven't had problems with the drives not being able to keep up.  I do, 
however, keep my MySQL database on a separate drive.
