HGST 750GB 2.5" HDD

The HGST HTS541075A9E680 is a 2.5" Travelstar mobile hard drive offering 750 GB of storage in a slim 9.5 mm profile. Its combination of capacity and power-efficient 5400 RPM operation suits laptops, small desktops and embedded systems that need larger storage without high power draw.

The drive uses a two-platter design (approximately 375 GB per platter), 8 MB buffer and a Serial ATA interface. It supports Advanced Format (512e/4K sector emulation), giving efficient handling of large files — suitable for multimedia storage, backups and light-duty applications where sustained throughput matters more than peak performance.

Common uses: upgrading a laptop’s internal storage to increase capacity, putting into a compact external enclosure for archive backups, or deploying in media/recording devices that require stable, high-capacity spinning storage with modest power consumption.
