Anyone using these drives? I just ordered one Western Digital WD Green WD10EZRX 1TB IntelliPower SATA 6.0Gb/s 3.5" Just curious what users think or if anyone has had issues. "IntelliPower - A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance." "Advanced Format (AF) - Technology being adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities."
