What's everyone's opinion ? WD Green drive: love the low power consumption but reliability seems to be suspect in 24/7 server use as Intellipark energy savings features park the head after 8 seconds and forces and excessive number on/off cycles lowering life expectancy. Price is ok. WD RED : No intellipark and better warranty. Designed for server and NAS. price is higher - makes me wonder if its worth it. Energy savings is great and similar to green drives as it operates at 5400rpm. Seagate 3TB: superior performance. No intellipark. Sells much cheaper than both. $30-$49 cheaper almost always. But uses more energy. Which should I get ?
