500 GB SATA laptop drive
The Seagate Momentus 5400.6 ST9500325ASG is a 2.5 inch internal hard drive with a 500 GB capacity. It spins at 5400 RPM and connects through a SATA 3.0Gb/s interface with an 8 MB cache. The bare drive measures 9.5 mm in height for standard laptop bays.
Quiet upgrade for older notebooks
This drive suits users replacing a failed drive or adding storage to a compatible laptop that accepts a 2.5 inch SATA device. G-Force Protection and a 1000 Gs non-operating shock rating help protect data from drops. Buyers needing higher throughput or lower access latency should consider alternative storage types.
5400 RPM spindle speed
The 5400 RPM rotation rate determines the drive's baseline latency and sustained transfer performance. Average latency is specified at 5.6 ms. This single figure defines whether the drive meets the performance requirements of the intended system.

Questions about this item
Does the 5400 RPM ST9500325ASG need any scheduled maintenance or bearing replacement?
No scheduled maintenance is required for the 5400 RPM mechanism; the drive is sealed and the fluid-dynamic bearings are rated for the life of the unit.
What limit appears first when the Momentus 5400.6 runs sustained writes at 3.0 Gb/s?
The 5400 RPM spindle and 8 MB cache set the sustained throughput ceiling well below the 3.0 Gb/s SATA link speed.
How much heat and noise does the 9.5 mm ST9500325ASG produce in an all-day laptop workload?
QuietStep technology keeps acoustic output low and the 5400 RPM speed limits heat, so the drive stays cool and quiet during continuous use.
