Seagate Momentus 500 GB 5400 rpm laptop drive

This Seagate Momentus is a 500 GB 2.5-inch SATA hard drive that spins at 5400 rpm with an 8 MB buffer. It is built for standard laptops and small-form-factor PCs that use a 2.5-inch SATA bay. The drive is supplied new and the retail or OEM packing may vary.

Suits upgrades where capacity and low power matter

This drive suits anyone adding storage to a laptop or compact desktop where a 500 GB SATA disk is the correct fit. Buyers who need more capacity, a faster spindle speed, a larger cache or a solid-state drive should look at something else.

5400 rpm spindle speed decides the fit

The single specification that decides whether this is the right part is the 5400 rpm spindle speed. It sets the drive's performance tier, power draw and acoustic profile, so match that figure to the system's requirements before ordering.

Questions about this item

Will the 5400 rpm spindle or the 8 MB cache need any service or replacement over time?

The drive is a sealed mechanical unit with no user-serviceable parts; neither the 5400 rpm spindle nor the 8 MB cache requires maintenance or scheduled replacement.

What limits sustained throughput first, the 5400 rpm platters or the SATA 3Gb/s interface?

The 5400 rpm platters determine the maximum sustained transfer rate; the SATA 3Gb/s link provides more bandwidth than the mechanical media can deliver.

How much heat and noise does the drive produce when running continuously in a laptop?

Designed for low-power operation, the Momentus generates minimal heat and operates at whisper-quiet acoustic levels during all-day use.
