Ideal for servers and mobile devices

The HGST HTS545050A7E680 is a 2.5-inch internal hard drive built for servers, notebooks, external enclosures and gaming consoles. It delivers 500GB of storage on a single platter using a SATA 6.0Gb/s interface and 8MB cache.

500GB capacity with 4K sector efficiency

Advanced Format increases the physical sector size to 4096 bytes with 512 byte emulation, improving error correction and areal density. The 5400 RPM spindle and low power consumption suit always-on or battery-powered systems, though sustained throughput is limited by rotational speed.

Direct replacement for 9.5mm standard drives

The 7mm z-height fits thinner chassis where 9.5mm drives cannot install, making the upgrade worthwhile for space-constrained notebooks or consoles. Self-encrypting variants add hardware encryption for data security, while standard models serve buyers who do not need that feature.

Questions about this item

Will this 2.5" SATA 6.0Gb/s drive work in a laptop that only supports SATA 3.0Gb/s?

Yes, the 6.0Gb/s interface is backward compatible with 3.0Gb/s SATA controllers, so the 500GB drive will operate at the slower link speed.

How can I verify the Advanced Format 4096-byte sectors are active after installation?

Use a partitioning tool or OS disk utility to check the physical sector size; it should report 4096 bytes with 512-byte emulation for legacy software.

Does the 0J47805 package include a mounting bracket or SATA cable for a desktop PC?

The drive ships as a bare 2.5" unit; a 2.5-to-3.5" adapter bracket and a standard SATA data cable must be purchased separately for desktop mounting.
