Fikwot FX660 2TB

Manufacturer: Fikwot

The Fikwot FX660 2TB is an M.2 NVMe solid-state drive built around the PCIe 4.0 interface, offering sequential read speeds of up to 5200 MB/s and sequential write speeds reaching 4700 MB/s. It uses the NVMe 1.4 protocol and is designed without an integrated heatsink or RGB lighting, keeping the form factor straightforward for standard desktop and laptop installations.

Under the hood, the FX660 relies on a Realtek RTS5766 controller with 4 channels and QLC NAND flash storage across its 2000 GB capacity. The drive carries a PassMark score of 23923, operates without DRAM cache, and has a maximum operating temperature of 70 °C. Endurance is rated at 640 TBW, and the drive is backed by a 5-year warranty.

Pros
  • Sequential read speed of 5200 MB/s and write speed of 4700 MB/s indicate strong throughput over the PCIe 4.0 interface
  • NVMe 1.4 support enables efficient command queuing and lower latency for data transfers
  • 2000GB of internal storage provides substantial capacity for large libraries of files or applications
  • A 5-year warranty period offers meaningful long-term coverage
  • TBW rating of 640 terabytes provides a clear endurance baseline for sustained write-heavy workloads
  • The absence of a heatsink and RGB lighting keeps the physical profile simple and unobtrusive, suitable for space-constrained builds
Cons
  • QLC NAND flash typically degrades in sustained write performance more readily than TLC or MLC alternatives under heavy workloads
  • No DRAM cache means the controller lacks a dedicated buffer, which can affect consistency during mixed or random workloads
  • The Realtek RTS5766 controller uses only 4 channels, which limits parallelism compared to higher-channel-count controllers
  • Maximum operating temperature of 70 °C leaves a relatively narrow thermal headroom without an integrated heatsink
  • PassMark score of 23923, while measurable, reflects the combined constraints of QLC storage and the absence of DRAM caching
Who is this for?

This drive is well-suited to users who need high sequential throughput over PCIe 4.0 for tasks such as transferring large files, loading substantial game libraries, or handling media that benefits from fast read and write rates. With 2000GB of capacity and a 5-year warranty backed by a 640 TBW endurance rating, it fits users who want a high-capacity M.2 drive for a mainstream desktop or laptop build without the bulk of a heatsink or the visual noise of RGB lighting.

Who is this NOT for?

This drive is less suitable for users running sustained, write-intensive workloads such as continuous video recording, large database operations, or server-grade tasks, where QLC NAND without a DRAM cache can struggle to maintain consistent performance. It is also a poor match for environments requiring tight thermal headroom management, since the lack of an integrated heatsink combined with a 70 °C maximum operating temperature leaves little buffer under prolonged load in poorly ventilated enclosures.

The Fikwot FX660 2TB is an M.2 NVMe SSD operating over PCIe 4.0 with NVMe version 1.4, offering 2000GB of internal storage built on QLC NAND flash. It uses a Realtek RTS5766 controller with 4 channels and carries no DRAM cache. The drive has a TBW rating of 640 terabytes and a maximum operating temperature of 70 °C, with a 5-year warranty included. It does not feature an integrated heatsink or RGB lighting.

Final Verdict

The Fikwot FX660 2TB is a straightforward M.2 PCIe 4.0 NVMe drive that delivers meaningful throughput for everyday high-capacity storage needs, anchored by a 5200 MB/s sequential read speed and a generous 2000GB of usable space. Its 5-year warranty and 640 TBW endurance rating provide a reasonable degree of confidence for long-term use, though the combination of QLC NAND and no DRAM cache means it is best appreciated in workloads that favour large sequential transfers over sustained random write performance. For users building a mainstream system who need ample storage with PCIe 4.0 bandwidth and a clean, unobtrusive form factor, the FX660 2TB is a functional and well-defined option within its intended scope.
