FX660 1TB M.2 SSD PCIe Gen4 NVMe - Fast Storage Upgrade

In this review of the FX660 1TB M.2 SSD, the bottom line is simple: it is a strong, affordable NVMe option for anyone who needs faster load times and larger capacity without fuss. The drive targets PC builders, laptop upgraders and PS5 owners who want a noticeable boost in game and application performance. Its main selling point is the combination of PCIe Gen4 x4 bandwidth and a Dynamic SLC cache that delivers high sustained transfer rates in everyday use.

Key Features

• PCIe Gen4 x4: Provides a high bandwidth interface so large files and games transfer much faster than SATA SSDs.
• Up to 4800MB/s read: Rapid read throughput reduces game load and application startup times on compatible platforms.
• Dynamic SLC cache: Improves real world write performance by accelerating small and burst writes for snappier file operations.
• Graphene heat sticker: Enhances heat dissipation without adding bulk, helping the drive sustain higher speeds under load.
• Wide compatibility: Works in desktops, laptops and PS5 hardware and supports major Windows versions for easy integration.
• Five-year warranty: Includes a 5-year registration warranty and basic toolkit in the box for a straightfoward install.

Who It's For

The FX660 is best for gamers upgrading storage on a PS5 or a desktop with an M.2 PCIe Gen4 slot, and for laptop users who need a capacity jump to 1TB with noticeably faster boot and load times. It is also a good fit for users migrating to NVMe from older SATA drives who want solid read performance without premium pricing.

Users who need enterprise-class endurance, hardware encryption, or the absolute fastest Gen4 speeds advertised by top-tier controllers should look elsewhere. Likewise, compatibility should be verified on older motherboards that lack Gen4 support to avoid bottlenecking the drive.

Pros & Cons

Pros

• Strong read performance up to 4800MB/s for faster game loads and file transfers.
• Dynamic SLC cache delivers improved write responsiveness for typical desktop tasks.
• Graphene heat dissipation sticker helps maintain peak rates under sustained load.
• Includes installation screws and a screwdriver plus a 5-year registration warranty.

Cons

• Write speeds peak around 2900MB/s, so it is not the fastest Gen4 drive for heavy sustained writes.
• Does not list advanced enterprise features such as hardware encryption in the documentation.
