750 GB 2.5″ SATA laptop drive

The HGST Travelstar 5K1000 HTS541075A9E680 is a 750 GB 2.5-inch internal hard drive built for laptop storage upgrades or replacements. It spins at 5400 RPM with an 8 MB cache and connects over a SATA 3.0 Gb/s interface. The drive ships as a bare unit in retail or OEM packaging.

SATA 3.0 Gb/s practical limits

The SATA 3.0 Gb/s interface caps the maximum theoretical transfer rate at 3.0 Gb/s, so sustained reads and writes will not exceed that ceiling. Real-world throughput is lower because of the 5400 RPM spindle speed and the 8 MB cache size. The 9.5 mm height fits most standard laptop bays but will not suit ultra-thin designs that require a 7 mm drive.

750 GB capacity decides fit

The single specification that determines whether this is the right part is the 750 GB capacity. Buyers who need more storage for large media libraries or multiple operating systems will find this limit restrictive. The drive has been erased to DoD 5220.22 M standard and tested good, though up to 25 bad sectors may be present.
