Review on WD 3TB Blue My Passport Ultra External Hard Drive - USB 3.0 - WDBBKD0030BBL-NESN by Oliver Phelps

I bought this to connect to a network video recorder for home security recording. I bought 3TB because I had no idea how much storage I was going to use, but looking back now I should have bought 1TB. Looks like I can record 4 camera alarms for a little under two years (90 weeks) before it starts overwriting - wow! H.264 compression and easy alarm storage reduce footprint. And don't get me wrong, my alarms go off everywhere, but each only records about 35 seconds, so it doesn't take up much storage during the week (about 30GB per week with 2.7TB of usable storage). memory after formatting).
