FANXIANG S660 1TB NVMe SSD

The FANXIANG S660 is a 1TB internal solid state drive built on PCIe 4.0 x4 and 3D NAND TLC. It targets gamers and PC builders who need fast sequential speeds for game installs and large file work. The drive also fits PlayStation 5 expansion slots with its included heatsink. ||

M.2 2280 Form Factor with Manual Heatsink

The drive uses the standard M.2 2280 layout and measures 9.50mm tall once the heatsink is fitted by hand. That height clears most laptop bays and desktop motherboards, though the manual step adds a minute to installation. The aluminium heatsink spreads heat across a larger surface so sustained writes stay within the 0°C to 70°C operating window. ||

DRAM-Less Design with HMB and SLC Cache

Without a dedicated DRAM chip the controller leans on Host Memory Buffer and a dynamic SLC cache to hit 5000MB/s reads and 4500MB/s writes. The 700TBW rating and 2,000,000-hour MTBF show it can replace older PCIe 3.0 drives or smaller capacity sticks when the workload demands more throughput and endurance.

Questions about this item

What maximum sequential read speed does the PCIe 4.0 x4 interface cap the S660 at?

The PCIe 4.0 x4 interface limits the S660 to a maximum sequential read of 5000MBps and a maximum sequential write of 4500MBps.

What physical clearance does the 9.50mm heatsink height need in a laptop or PS5 slot?

The drive measures 9.50mm tall with the heatsink fitted, so the M.2 slot must accommodate at least that height plus the PCB.

How is the heatsink installed, and which step do people often miss?

The heatsink ships separately; you must peel the thermal pad liner, press the pad onto the controller, then screw the heatsink down — skipping the liner removal leaves an air gap.
