Drive identity and target use

The Toshiba MK6461GSYN is a 640GB 2.5 inch laptop hard drive built for daily computing tasks. It suits users who need a straightforward mechanical drive for a notebook or compatible enclosure. Buyers who want more storage or faster solid-state response will need a different drive.

Deciding specification

The drive runs at 7200 RPM with a 16MB cache over a SATA 3.0Gb/s interface. That spindle speed and cache size are the primary factors that determine whether the drive meets the performance needs of a given workload.

Thermals noise and power

Normal operation produces typical mechanical drive acoustics and heat for a 7200 RPM 2.5 inch unit. Power draw stays within standard SATA limits for this form factor. The 9.5mm height fits most laptop bays without clearance issues.

Questions about this item

What does the 7200 RPM speed mean for everyday use?

The 7200 RPM spindle and 12 ms average seek time provide quicker data access for operating system boots, application launches and file transfers in daily computing tasks

What does the SATA 3.0Gb/s interface limit in practice?

The SATA 3.0Gb/s interface caps the maximum transfer rate at 3.0 Gb/s, so sustained read and write speeds cannot exceed that bandwidth

Will the 9.5 mm height fit my laptop bay?

The drive measures 9.5 mm high, 69.75 mm wide and 100.3 mm long, matching the standard 2.5 inch form factor used in most laptop drive bays
