500 GB 2.5-inch SATA drive

The Seagate ST9500323CS is a 500 GB laptop internal hard drive with a 5400 RPM spindle and 8 MB cache. It connects through a SATA 3.0Gb/s interface and uses the standard 2.5-inch form factor. The bare-drive packaging makes it suitable for system builders and repair technicians.

Fits 9.5 mm bays with SATA power and data

The drive measures 9.5 mm in height, 69.85 mm in width and 100.35 mm in length, matching the common 2.5-inch notebook bay. It requires a SATA data cable and a SATA power connection from the host system. Using this mechanical drive frees an M.2 slot for a faster solid-state boot device.

Suits storage upgrades and secondary data volumes

This unit suits users who need affordable bulk capacity for documents, media or backups in a laptop or external enclosure. Buyers who want faster application loading or a primary operating-system drive should look at a solid-state alternative.

商品問答

How long can the 5400 RPM spindle sustain writes before thermal throttling becomes the limit?

The 5400 RPM motor and 8 MB cache are designed for continuous laptop workloads; the drive operates within its thermal envelope for typical all-day use without a stated throttle point.

What are the noise and heat levels when the drive runs all day in a laptop?

At 5400 RPM the acoustic profile is a low hum and the 9.5 mm z-height keeps heat output modest for a 2.5" bay; no specific dB or watt figures are published.

Which existing laptop connector and bay size are required for the SATA 3.0Gb/s interface and 9.5 mm height?

A standard 2.5" SATA slot with a 9.5 mm drive bay is needed; the drive measures 69.85 mm wide by 100.35 mm long and uses the SATA 3.0Gb/s interface.
