Seagate ST31000524AS - 1TB 7.2K RPM 6G MDL NHP LFF 3.5" SATA Hard Disk Drive (HDD)

This "refurbished" 3.5-inch drive is serving as an exact replacement for an identical drive that came in a new Dell computer I purchased 11 years ago. The drive it replaced had heavy usage during those 11 years, without a glitch until recently. It was worn out. The hardware statistics on the replacement unit indicate that it had very light usage in its previous service. I purchased it from cpumedics.com and, although it cost a bit more than I wanted to pay for a replacement drive, it is installed and working perfectly, and I am delighted with my purchase.
