Enterprise 750 GB SATA drive
The Seagate BarraCuda ES ST3750640NS is a 750 GB 3.5 inch internal hard drive built for 24 x 7 operation in multi-drive environments. It spins at 7200 RPM with a 16 MB cache and connects through a SATA 3.0 Gb/s interface.
Bare drive with DoD erase
The unit ships as a bare drive without cables, brackets or software. Each drive has been erased to DoD 5220.22 M compliance and tested for function, though up to 25 bad sectors may be present and the drive is not formatted or partitioned.
3.5 inch form factor for desktop bays
The standard 3.5 inch size fits directly into desktop drive bays and backplanes using the SATA data and power connectors. Manufacturer warranty has ended; the seller provides a one year warranty instead. Labels or cosmetics may differ from the product image.

Questions about this item
What maintenance or replacement should I expect for the 750GB Seagate Barracuda ES ST3750640NS drive?
The drive is sold as used and tested to DoD 5220.22 M erasure standards. The supplier notes it may have up to 25 bad sectors and cosmetic markings. No manufacturer warranty remains; plan to replace the unit if sector count grows or SMART errors appear.
What limit appears first when the ST3750640NS runs sustained workloads at 7200 RPM?
The SATA 3.0Gb/s interface caps burst throughput at 3.0 Gb/s, and the 16MB cache fills quickly during long writes. Mechanical latency of 4.16ms and average write time of 9.5ms become the bottleneck before thermal limits are reached.
How much noise, heat and power does the 3.5" Barracuda ES produce when running all day?
As a 7200 RPM enterprise drive, it generates typical mechanical seek noise and measurable heat during continuous operation. The SATA 3.0Gb/s interface draws standard 3.5" drive power; expect audible clicks during seeks and a warm chassis after extended 24×7 use.
