640 GB 2.5" SATA notebook drive

The HGST HTS547564A9E384 is a 640 GB laptop internal hard drive with a 5400 RPM spindle and 8 MB cache. It connects through a SATA 3.0Gb/s interface in a standard 2.5 inch form factor. Average seek time is 12 ms and average latency is 5.5 ms. The unit is supplied as a bare drive.

Suits older laptops and basic storage upgrades

This drive fits notebooks that accept a 2.5 inch SATA disk and need modest capacity for everyday files. It is not for systems that require a faster spindle speed or a larger cache for heavy workloads. Buyers who want more storage space should look at higher-capacity models. The refurbished condition means it has been tested and restored to working order.

SATA 3.0Gb/s interface decides compatibility

The single specification that determines whether this is the right part is the SATA 3.0Gb/s interface. The host system must provide a matching SATA data and power connection for a 2.5 inch drive. If the laptop uses a different interface or form factor, this drive will not install.

Questions about this item

Should I pick the 640GB version or is there a larger capacity available?

This model is offered in a single 640GB capacity; no larger version of the HTS547564A9E384 is listed.

What does the 5400 RPM rating mean for everyday laptop use?

The 5400 RPM spindle speed gives an average seek time of 12ms and average latency of 5.5ms, typical for standard notebook workloads.

Does the SATA 3.0Gb/s interface limit the drive's throughput in my system?

The SATA 3.0Gb/s link caps the maximum transfer rate at 3.0Gb/s, so sustained reads and writes cannot exceed that bandwidth.
