I bought these to fill a ReadyNAS Duo v2, I have bought this line previously and it pays to buy spares at the same time. Green. Red. Black. This is always a good idea. Green tend to run cooler and draw less current, and these are on 24x7. Speed was not a factor as any real throughput is throttled by the network. Rebuilding RAID (impaired) is the only real time SATA3 is important to me. The 64MB buffer will soften the blow for most files anyway, and your OS might cache the writes as well. The units are running as expected. This capacity is good bang for buck value, given that 4TB drives are 5 or 6 times the cost. I sleep in the same room as these and they are pretty quiet. I recommend these for desktop usage as an additional drive, especially for downloads that can be re-performed but are otherwise huge, such as from Steam or iTunes. Avoid writing more than one huge file at once (multiple iTunes downloads) as these disks do not like being thrashed for any length of time.Read full review
As I'm using this for a backup drive and not a program or primary data drive, I'm happy with the slower RPMs.
