250 GB laptop drive for storage upgrades

This 2.5-inch Samsung Spinpoint M7 drive adds 250 GB of capacity to a notebook or external enclosure. It suits owners who need more room for documents, media or a second operating system without changing the laptop’s drive bay.

5400 RPM spindle speed sets performance

The platters rotate at 5400 RPM with an 8 MB cache and a SATA 3.0Gb/s interface. Average seek time is 12 ms and average latency is 5.6 ms, so sustained transfers suit everyday workloads rather than heavy random access.

Fits 9.5 mm bays with standard SATA power

The drive measures 9.5 mm high and uses the common 2.5-inch SATA data and power connectors. It slides into any laptop bay or caddy that accepts a 9.5 mm drive, leaving the M.2 slot free for a faster boot SSD.

Questions about this item

How does the 5400 RPM speed affect everyday laptop use?

The 5400 RPM spindle delivers a 12 ms average seek time and 5.6 ms latency, which is typical for routine office tasks and media playback on a 2.5 inch drive.

What does the SATA 3.0Gb/s interface mean for transfer speeds?

The SATA 3.0Gb/s link caps the theoretical burst rate at 3.0 Gb/s; sustained throughput will be lower and depends on the 5400 RPM platters and 8MB cache.

Will this 2.5 inch drive fit a standard 9.5mm laptop bay?

Yes, the drive has a 2.5 inch form factor and a maximum height of 9.5mm, matching the common laptop drive bay specification.
