I have also scanned the forums with no issues about the spinpoint F3 and Raid 1. On a personal note i had just tried to install my F3 into my qnap TS219P in raid 1 with a disk read/write error on raid 1. After extensive test and trouble shooting it appears the qnap i may be faulty. I have just obtained another one from the reseller and i am yet to try the F3's in this new unit. I will let you know how the results go. If it develops any issue, then i would be suspecting the F3's then.
