HGST

HGST HTS725032A7E635 320GB 7200RPM 2.5" SATA internal hard drive

SKU CH-YK9W-XS86W

A 320 GB, 7200 RPM, 2.5-inch SATA laptop drive with 32 MB cache and low power consumption

  • 320 GB capacity stores large media libraries
  • 7200 RPM spindle speed accelerates application loading
  • 32 MB cache buffer smooths burst data transfers
  • SATA 6 Gb/s interface enables fast host communication
  • Low power consumption extends laptop battery life

Ideal for laptop upgrades

This 2.5-inch SATA hard drive delivers 320 GB of storage and spins at 7200 RPM for responsive everyday performance. It is built for notebooks that need a reliable mechanical drive with a 32 MB cache and 6 Gb/s interface. The halogen-free design supports an eco-friendly footprint while keeping power draw low.

Fits standard 2.5-inch drive bays

The drive connects directly to a laptop SATA III controller without adapters or extra cables. Its low power consumption helps preserve battery life and reduces thermal load inside compact chassis. Builders gain a straightforward storage increase that works with any system accepting a 2.5-inch SATA device.

320 GB capacity with 32 MB buffer

The cache smooths burst workloads such as application launches and file copies. The 7200 RPM spindle provides faster sequential access than slower laptop drives. Heavy media libraries or large game collections will exceed the available space, so users with growing storage needs should plan for a larger drive or external backup.

商品問答

How long can the HTS725032A7E635 sustain 7200 RPM before thermal throttling reduces throughput?

The 32 MB buffer helps absorb burst writes, but the drive has no published sustained-transfer limit; monitor SMART temperature during heavy workloads.

What is the typical noise and power draw of the HGST Z7K500-320 when it runs continuously in a laptop?

It is rated for low power consumption and halogen-free construction; expect a quiet 2.5 inch profile with 320 GB capacity at 7200 RPM.

Which existing laptop interface and form-factor does the 2.5 inch SATA 6 Gb/s drive require to operate?

It needs a standard 2.5 inch SATA III 6 Gb/s bay and a SATA data-plus-power connection; no extra adapter is required.
