Laptop hard drive for storage upgrades

The Seagate ST9500423AS is a 2.5 inch hard drive designed for laptop storage expansion or replacement. It provides 500GB of capacity and spins at 7200 RPM with a 16 MB cache. This drive suits users needing more space for applications and files on compatible portable systems.

Check SATA interface and 2.5 inch bay compatibility

Verify that the laptop accepts a 2.5 inch SATA hard drive before ordering. The drive uses a standard SATA connection rated at 3Gb/s and supports hot swap functionality. Ensure the system BIOS recognises the drive capacity and that the physical drive bay matches the 2.5 inch form factor.

Thermals noise and power in normal use

The 7200 RPM spindle speed produces typical mechanical drive noise and heat during operation. Power draw follows standard 2.5 inch SATA hard drive levels for this rotational speed. Adequate laptop ventilation manages the thermal output during sustained read or write activity.

Questions about this item

Does the ST9500423AS come with mounting brackets, screws or cables, or must they be purchased separately?

The drive is supplied as an OEM bare unit; no brackets, screws or SATA cables are included and must be sourced separately.

How do I decide between the 500 GB 7200 RPM model and other capacities or speeds for a laptop upgrade?

Choose the 500 GB 7200 RPM version when you need maximum internal storage and the quickest mechanical access times available in a 2.5 in SATA form factor.

What does the 7200 RPM figure mean for everyday laptop use once the drive is installed?

The 7200 RPM spindle combined with 16 MB cache reduces seek latency and raises sustained transfer rates, giving snappier boot and application loading compared with slower-spinning laptop drives.
