It delivers sequential read speeds up to 4800MB/s and write speeds up to 4500MB/s, which makes it a solid choice for speeding up system boot times and cutting game loading screens. The drive uses 3D NAND TLC flash memory, offering better endurance and stability compared to QLC-based alternatives. This M.2 2280 drive is compatible with laptops, desktops, and the PS5 console, and it ships with an aluminum heatsink and thermal pad already attached. That means you can install it into a PS5 expansion slot without buying extra cooling parts. Positioned in the entry-to-mid tier of PCIe Gen4.0 SSDs, the S660 targets users who want large capacity and fast transfer speeds without spending flagship money. ## Compatibility Guide The S660 2TB uses the M.2 2280 form factor and connects over PCIe Gen4.0 x4. It will also work in PCIe 3.0 slots, but the transfer speed will be capped by the older interface's bandwidth. To get the full 4800MB/s read performance, your motherboard or laptop must support PCIe 4.0. For PS5 owners, this drive is confirmed to work with the console's internal expansion slot. The included heatsink fits within the PS5's clearance requirements, so no additional parts are needed. On desktop PCs, simply insert the drive into an available M.2 slot. Remember that a fresh drive needs to be partitioned and formatted before the operating system will recognize it. ## Product Info The fanxiang S660 2TB is a PCIe Gen4.0 x4 NVMe SSD with maximum sequential read and write speeds of 4800MB/s and 4500MB/s respectively. It relies on dynamic SLC caching and HMB (Host Memory Buffer) technology to accelerate performance. Endurance is rated at up to 1400TBW, with an MTBF of 2 million hours. In the current SSD market, this drive sits in the entry-to-mid tier of PCIe Gen4.0 models. The bundled heatsink and PS5 compatibility make it a convenient option for first-time NVMe buyers who want a complete package. The drive comes with a 5-year warranty, and the manufacturer offers technical support for questions after purchase. ## Best Use Cases - Gamers who want to expand PS5 storage: this drive is confirmed compatible and includes a heatsink, so you can install it directly into the console's expansion slot. It is not suitable for older PS5 models without the expansion bay. - Laptop users looking to upgrade from a slow SATA drive: the M.2 2280 size fits most modern notebooks, and the low power draw helps preserve battery life. Note that older laptops with only PCIe 3.0 will not reach the full advertised speeds. - Desktop users who need 2TB of fast storage for large game libraries or video files: the high TBW rating provides peace of mind for frequent writes. If you are still on a SATA SSD, the jump in load times will be immediately noticeable. ## Things to Consider To achieve the maximum transfer rates, your system must support PCIe Gen4.0. On a PCIe 3.0 platform, the drive will still function but the speed will be limited to roughly half of the rated throughput, so upgrading an older machine may not deliver the expected performance boost. While the drive is confirmed to work with the PS5, future console system updates could potentially affect compatibility. It is wise to check the latest official information before purchasing if the drive is intended primarily for a PS5. Compared to SSDs with a dedicated DRAM cache, the S660 uses an HMB design. Random access performance may be slightly lower in some workloads, though for gaming and general file transfers the difference is rarely noticeable in everyday use. ## FAQ Q: Do I need to buy a separate heatsink for PS5 installation? A: No. The S660 comes with an aluminum heatsink and thermal pad pre-installed, so it can be mounted directly into the PS5 expansion slot without additional cooling parts. Q: Will this drive work in a PCIe 3.0 motherboard? A: Yes, it will be detected and function normally. However, the transfer speed will be limited to the PCIe 3.0 bandwidth, which is roughly 3500MB/s maximum, so you will not see the full 4800MB/s read speed. Q: How long will the 2TB model last? A: The endurance rating is up to 1400TBW. Assuming 1TB of writes per day, that translates to approximately 3.8 years of continuous heavy use. For typical gaming or OS drive workloads, this provides a comfortable margin. ### Product Disclosure (Amazon) - Manufacturer: fanxiang - Model: S660 - ASIN: B0CJLJXT9T - Note: This article covers a manufacturer-made product based on Amazon listing details.
