How much does a drives RPM make a difference?
I have two ReadyNAS NV+ units that I use in a home environment. One of the NV+ units is used to back up some (but not all) of the data from the primary NV+ unit. I have 5 Macs, two AppleTVs, two TiV...
From yoh-dah regarding 5900 RPM drives:
In the case of an NV+ or Duo, they can only push 25-35 MB/s so I doubt that the performance hit would even be noticeable.
I recently bought 2 Hitachi HDS723020BLA642 drives for 109.00, although they're now 99.00 each:

That said, if you were to use the 5900 RPM LP drives, you'll get about a 10% difference in performance. So rather than 100 MB/sec, you'll get around 90. That being the case, home systems won't be able to push anywhere close to that w/o using RAID, SSD, or a 15K RPM drive on the client. And the advantage with the LP drives (which by the way the loaded systems are shipped with), there's a good power saving if you're running it 24/7.

How to read the Deskstar model number
HDS723020BLA642 = 2TB, 64MB buffer
H = Hitachi
D = Deskstar
S = Series prefix
72 = 7200 RPM
30 = Full capacity—3TB
20 = Capacity this model, 30 = 3TB (20 = 2TB, 15 = 1.5TB)
B = Generation code
L = 26.1mm z-height
A6 = Interface, SATA 6Gb/s
4 = 64MB buffer
0 = Reserved (2 = Reserved)
