hello friends,
In the course of writing the review, I was struck by the fact that for the average home server/NAS owner, selecting the right storage for your rig is more complicated that it ever has been. In the past, it was easy – you had consumer desktop drives and enterprise drives. Given the scarily-high prices of the latter, it was a simple choice.

But then came the so-called “green” drives – desktop drives with a low-power twist. Then the aforementioned NAS drives, “pro” drives for small business, drives for enterprises, drives for data centers, drives for surveillance equipment. Each with SATA 3 Gb/s and 6 Gb/s options. Sure, you could just go for the ones that say “NAS” right? That would save you a lot of time worrying about selecting the right drive, wouldn’t it? As the manufacturers have done the worrying for you!
