Momentus 500 GB 2.5-inch SATA drive

The Seagate Momentus ST9500423AS is a 500 GB 2.5-inch internal hard drive that spins at 7200 RPM and connects through a SATA 3 Gb/s interface with a 16 MB cache. It is built for laptop bays and other 2.5-inch drive slots that accept a standard SATA connection. The drive is supplied new and carries the manufacturer model number 9RT143-021.

Suits laptops needing a 2.5-inch SATA drive

This drive fits laptops and compact systems that require a 2.5-inch SATA hard drive with a 7200 RPM spindle speed. It is not suitable for desktops that only have 3.5-inch bays unless an adapter bracket is used. Buyers who need a faster solid-state drive or a higher-capacity mechanical drive should consider other options.

SATA 3 Gb/s interface decides compatibility

The single specification that determines whether this is the correct part is the SATA 3 Gb/s interface. The host system must provide a matching SATA data and power connector for a 2.5-inch drive. If the system uses a different interface or only accepts 3.5-inch drives, this unit will not install without additional hardware.

Questions about this item

Which capacity and speed version of this Momentus drive should I pick?

The drive is offered as a single 500 GB model spinning at 7200 RPM with a 16 MB cache, so there are no alternative capacities or speeds to choose from.

What does the 7200 RPM rating mean for everyday laptop use?

The 7200 RPM spindle delivers faster data access and shorter load times than slower laptop drives, improving responsiveness when opening files or launching applications.

How does the SATA 3 Gb/s interface affect performance in my laptop?

The SATA 3 Gb/s connection sets the maximum link speed, and the drive’s 16 MB buffer helps maintain throughput during burst transfers.
