Also I recommend getting something larger. Even if you don't need more than 1TB now if the drive lasts for a few years you will probably find a need for more. 4TB SATA disks are getting cheap nowadays.
I recommend getting something smaller and have multiple drives in case of drive failure, but thats just my opinion.
http://cdn.msy.com.au/Parts/PARTS.pdf MSY has 1TB disks for $69 and 2TB for $99. 2TB is significantly better value for money and it's cheap enough that multiple drives isn't expensive. Also due to the incidence of small numbers of bad sectors that are correlated to disk location a RAID-1 array on a single disk will save you more often than you would expect. A 2TB disk with a RAID-1 on 2 partitions will be significantly less likely to lose data and doesn't cost much more. I have some backup disks with bad sectors that I use as BTRFS RAID-1, they work well for me. A total failure of a disk is very rare as is a failure where you get tens of thousands of errors. Most drive problems have dozens of errors. As an aside I had a BTRFS drive give 12,000+ read errors. Due to metadata duplication (basically RAID-1 for metadata) I could read most of the data off it. Even 12,000 read errors isn't that much from a 2TB disk, as long as the metadata duplication saves the root directory etc you don't lose much. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
