I have 2 of these. The price below is per drive. Brand new they are $100 each. Both drives are about a year old + or -. They were lightly used while I had them. No crazy re-writes, transfers or multiple formats. I baby all of my computer components, so these were installed using anti-shock/vibration dampening mounts. Also, well cooled. 64MB Cache, SATA 6 GB/s. 3.5".
