When building a NAS in the past, the consumer generally had two choices: dip into hard drives that weren't really built to be stacked next to each other in a cramped environment and run for 24 hours, or splash out for an enterprise drive that cost the world.
Those who opted for choice one and bought "green" drives, for the fact that they were cheaper, ran slower and were therefore cooler, often found themselves in the bind of drives dropping from their arrays, as TLER or whatever equivalent either shipped as disabled or simply wasn't there.
So it's nice that Western Digital has spotted a niche to tackle: that of the NAS drive. Its new Red drives are built specifically to live in that tiny box in the corner of your room, including shipping with TLER on by default, technology to minimise vibration and the adjustable spindle speed of the green drives to keep heat, and technically energy bills, down.
It's also backed up with a three-year warranty, which while not extraordinary is.
