640 GB 2.5" laptop drive

The HGST HTS727564A9E364 is a 640 GB internal hard drive built for 2.5 inch laptop bays. It spins at 7200 RPM and arrives as a new bare drive in retail or OEM packaging. The 0J18842 part number matches the manufacturer listing for this model.

Ideal for capacity upgrades

This drive suits owners of compatible laptops who need more storage space and want the responsiveness of a 7200 RPM spindle. It is not for systems that only accept 7 mm or thinner drives, nor for users who require the speed of solid-state storage.

7200 RPM spindle speed

The 7200 RPM rotation rate is the specification that determines whether this drive meets the performance expectation for a mechanical laptop upgrade. Buyers should confirm their system supports a standard 2.5 inch form factor before purchase.

Questions about this item

How do I install the 2.5 inch HTS727564A9E364 into my laptop, and which step is often missed?

Slide the 640GB drive into the 2.5 inch bay, attach the connector, then secure it with the mounting screws; the step often missed is tightening those screws so vibration from 7200 RPM operation does not loosen the connection.

What maintenance or replacement will the HTS727564A9E364 need later?

No routine maintenance is required; the 640GB 7200 RPM drive should be replaced only if SMART errors appear or the mechanism becomes noisy.

What limit appears first on the HTS727564A9E364 under sustained use?

The 7200 RPM spindle speed sets the maximum sustained transfer rate, so throughput plateaus at the mechanical limit during long sequential workloads.
