Unfortunately I found this out the hard way.

I just bought 2 1 TB WD Green Drives using the new formatting. (4K Sectors) I can write ~700K/second. Obviously this is painfully slow as I have 240 gigs currently to transfer.
Any word if there will be a fix?
I'm running Raid 1.
Will setting one of the jumpers on the back of the drive solve the problem?
