Western Digital, WD-Red NAS 3.0 TB Hard Drives. Model: SATA / 64MB Cache WD30EFRX. I have Three drives and they’re in like new condition. They were used in a third back-up copy, and they have been written-on only once or twice. New cost at amazon.ca is about $100 plus taxes, I am selling them at $40 each or all three at $100. Note, one drive has a black label, but they’re all suppose to be Red. Any questions, feel free to contact me.
