320GB 5.4K RPM SATA 7mm 2.5-Inch Hard Drive for Laptop Notebook Computers

This 320GB 5400 RPM mechanical hard drive is a slim 7mm 2.5-inch SATA replacement for compatible laptops, notebooks, compact desktops, and all-in-one computers.

★ Cross Reference / Cross-Sell

Turn this internal hard drive into portable USB storage or connect it externally for file transfers, cloning, recovery, and backups with the SuperSpeed USB 3.0 2.5-Inch SATA Hard Drive External Enclosure. The enclosure accepts 2.5-inch SATA drives and is powered through USB, so it does not require a separate AC adapter.

⚙️ Fit Notes

• Confirm that the computer uses a removable 2.5-inch SATA drive. Model-family compatibility alone is not sufficient because some systems were offered with different storage configurations.
• This 7mm drive fits native 7mm bays and most 9.5mm 2.5-inch SATA bays. Reuse the original caddy, rails, screws, connector interposer, rubber filler, or height spacer when required.
• This drive is not compatible with M.2 SATA, M.2 NVMe, mSATA, PCIe, 1.8-inch, IDE/PATA, or SAS-only connections.
• Replacing a 500GB drive with this 320GB drive reduces available capacity. Confirm that all source data will fit before attempting to clone the original drive.
• A replacement hard drive may require operating-system installation, recovery media, partitioning, formatting, or cloning. Software and recovery media are not included.
• Apple installations require the original SATA cable, mounting bracket, mounting posts, screws, and any model-specific carrier components.
• A 320GB drive displays approximately 298GiB before formatting and recovery partitions because drive manufacturers and operating systems calculate capacity differently.
• The exact manufacturer, label, cache size, and SATA link revision may vary by interchangeable model.
