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.
