I have 2 Caviar Green a WD10EADS and a WD10EARS
I bought the second when i got problem with WD10EADS and after installed the second i search over internet and found that they must be partitioned in a good way and even if ubuntu should do during installation, it doesn't.
My BIG problems was not about performance (maybe i can't see it viewing movies, i should play games...), but both of them lost the "partition table". (the first after 6 months, the second after 1 month...). It was very difficult to recover a XFS partition especially because i wrongly make an extended partition....
Now i follow the instruction, i backed up the partition table (sfdisk -d /dev/sda > backup-sda.sf) and the disk is very good (since 2 month...), extremely silent and low power.
By the way....I have a RAID 1 partition for the "Important recordings", very easy to do with mdadm....
