✔️ OEM Part Number Match: Compatible replacement when your existing drive label matches any part number listed above (Dell/HP/HGST/Seagate cross-references)

☑️ Key Features

☑️ Self-Encrypting Drive (SED) for hardware-based encryption support (Opal-class, label/firmware dependent)
☑️ 7mm thin profile for ultrabooks and “Laptop Thin” drive bays
☑️ 7200 RPM performance in a 2.5-inch laptop form factor
☑️ SATA 6Gb/s interface with broad backward compatibility

⚙️ Fit Notes

• This is a 7mm drive. If your laptop requires 9.5mm, you may need a spacer/bracket.
• SED features require supported BIOS/OS/encryption software to manage authentication and policy. Without SED management enabled, the drive typically operates like a standard SATA HDD for normal use.
