So I am about to start piecing together the rest of my General Purpose Server/NAS and I see a significant growth in 2.5" Drives. WD is even marketing some Red 2TB drives now. For a 8drive system would this offer significant heat/power/noise savings over going with 3.5" drives? Granted there looks to be a $75 premium on those 2.5" drives, but in Alaska, I might can make that up in a couple of years in power savings.
Speed is really not a priority. My 4x750gb WD Sata II greens can run 100mb/s writes in Raid 5 which is more than sufficient. My file output at most would be needing a sustained 30-40mb/s read to support a couple of 1080P quality streams to XBMC powered HTPCs.
System is:
Supermicro H8SGL
AMD Opteron 6128
8gb Corsair XMS3-1333
HighPoint RocketRaid 2720
Raid 5:4x WD 750GB Green
Windows Server 2012 R2 Standard
Fractal Define R4
