I want to buy a 2TB HDD for my D-Link DNS-325 NAS box. It will run over a wireless network (under a Linksys E2500 router).
As "green" HDDs are much much cheaper, I wanted to understand the importance in a NAS use of parameters such as rpm (5400 vs 7200), cache (32 vs 64) and connection speed (3GBpS vs 6GBpS) and other similar parameters.
I'm looking at WD black and green HDDs, the price difference is around $100 and while I'm willing to invest it I want to make sure that it's worth it when my HDD will be in a NAS box over wireless network (I want to make sure that the network factor won't be the bottleneck / limiting factor).
What speed wireless do you run? G or N?
If G then just get the 'green' drive as you will be limited on speed by the 54Mb/s wireless speed.
If you are running N then go ahead and get the 7200 rpm drive, especially if any comps will connect wired to the NAS.
