Fikwot FX660 1TB

Manufacturer: Fikwot

The Fikwot FX660 1TB is an M.2 NVMe solid-state drive built around the PCIe 4.0 interface, offering sequential read speeds of up to 4800 MB/s and sequential write speeds reaching 2900 MB/s. It uses QLC NAND storage and operates without an integrated heatsink or RGB lighting, keeping its design straightforward and focused on storage performance.

Under the hood, the FX660 is powered by a Realtek RTS5766 controller with four channels and complies with NVMe version 1.4. The drive carries a 320 TBW endurance rating, a maximum operating temperature of 70 °C, and ships with a five-year warranty. It records a PassMark SSD score of 23939 and includes no onboard cache.

Pros
  • Sequential read speed of 4800 MB/s over a PCIe 4.0 interface enables fast data access for demanding workloads
  • Five-year warranty period offers solid long-term coverage
  • A TBW rating of 320 terabytes indicates reasonable endurance for everyday and workload use
  • NVMe 1.4 compliance ensures broad compatibility with modern systems
  • The M.2 form factor fits standard slots without requiring additional mounting hardware
Cons
  • QLC NAND storage type generally has lower write endurance compared to TLC or MLC alternatives
  • No onboard cache, which can affect sustained write consistency under heavy load
  • Only four controller channels, which may limit parallelism in high-demand scenarios
  • Does not include an integrated heatsink, leaving thermal management dependent on the host system
  • Maximum operating temperature of 70 °C may be a limiting factor in thermally constrained builds
Who is this for?

This drive suits users who need fast sequential read throughput for tasks like loading large files, running operating systems, or handling application data at speed, thanks to its 4800 MB/s read rate over PCIe 4.0. Its M.2 NVMe form factor and five-year warranty also make it a practical choice for system builders seeking a reliable, compact storage upgrade with decent endurance for typical daily workloads within its 320 TBW rating.

Who is this NOT for?

Users who regularly push drives with sustained heavy write workloads — such as video editors writing large raw files continuously — may find the combination of QLC NAND and no onboard cache leads to inconsistent write performance under load. Similarly, those building in thermally constrained or passively cooled enclosures should take note of the 70 °C maximum operating temperature and the absence of an integrated heatsink, as adequate airflow would need to be provided by the host system to maintain stable operation.

It is driven by a Realtek RTS5766 controller operating across four channels and carries no onboard cache. The drive has a TBW rating of 320 terabytes and a maximum operating temperature of 70 °C, with a five-year warranty included. It does not feature an integrated heatsink or RGB lighting.

Final Verdict

The Fikwot FX660 1TB is a straightforward M.2 NVMe SSD that delivers on its core promise of fast sequential reads, with its 4800 MB/s read speed over PCIe 4.0 making it a capable choice for users looking to upgrade their system storage with a modern, compact drive. Backed by NVMe 1.4 compliance, a five-year warranty, and a reasonable TBW rating, it covers the fundamentals well for everyday and general workload scenarios. That said, its QLC NAND, cacheless design, and lack of an integrated heatsink mean it is best suited to moderate usage patterns rather than intensive sustained write operations. For users whose needs align with those boundaries, the FX660 1TB represents a functional and dependable storage option.
