Backed by a 3-year manufacturer warranty, this drive offers a reliable and affordable entry point into solid-state storage.

Key Features

  • 3D NAND flash technology: Provides better speed and durability compared to older 2D NAND
  • SATA III 6Gb/s interface: Fully utilizes SATA bandwidth for fast data transfers
  • 2.5-inch, 7mm form factor: Fits most laptops, desktops, and PS4 without modification
  • PS4 compatibility verified: Can replace the internal hard drive in PlayStation 4 (firmware 4.50+)
  • 3-year warranty: Long-term peace of mind from a trusted manufacturer

Compatibility Guide

This SSD is a standard 2.5-inch SATA drive. Ensure your system meets these requirements:

  • Storage interface: SATA III (6Gb/s) or SATA II (3Gb/s) – backward compatible
  • Form factor: 2.5-inch bay supporting 7mm thickness; some 9.5mm bays may require a spacer
  • Power: SATA power connector (desktop) or internal battery (laptop)
  • PS4: Requires system software version 4.50 or later. Follow official Sony instructions for replacement

Ideal Use Cases

  • Budget entry-level PC: Perfect as an OS drive for Windows or Linux, offering fast boot times
  • Reviving old laptops: Replacing an HDD with this SSD dramatically improves responsiveness
  • PS4 storage upgrade: Reduces game load times and improves overall console performance
  • Secondary storage: Suitable for documents and less frequently accessed files, but not for large media libraries

Upgrade Considerations

  • Capacity limitations: 128GB fills quickly with modern OS and applications. Consider 240GB or larger if you store many games or media
  • SATA vs NVMe: This drive uses the SATA interface, which is slower than NVMe. For most everyday tasks, the difference is negligible, and the cost savings are significant
  • Bottleneck potential: Connecting to a SATA II port will cap speeds, but still outperforms any HDD
  • No over-spec risk: This is an entry-level SSD; it will not be overkill for any typical use case
