Expecting restock
An affordable and balanced internal M.2 SSD with a small capacity (256 GB) featuring a PCIe Gen4 4x interface (NVMe 1.4 protocol) and durable 3D TLC NAND memory. Positioned as a budget-friendly product intended for home personal computers and entry-level to mid-range office systems. It comes in a bare design, adheres to the 2280 form factor sizes, and is compatible with a wide range of current motherboard models. It delivers decent sequential and random read/write speeds (up to 4000/2000 MB/s) with low latencies. The hardware base of the WD SN740 M.2 2280 SDDPNQD-256G SSD is a 4-channel, bufferless Polaris MP16+ controller. High-quality 112-layer 3D TLC NAND BiCS5 flash memory from Sandisk is used for storing user data. Thanks to the Host Memory Buffer technology, this model compensates fo...r the absence of a DRAM buffer by utilizing a small amount of RAM. The proprietary nCache 4.0 caching technology support provides increased write speeds. With no components on the back of the board, improved power management, and low heat generation, this drive is ideal for compact laptops and miniPC systems, where internal space is strictly limited. The use of high-quality 112-layer 3D TLC NAND BiCS5 from Sandisk, compatibility with a wide range of motherboards, and the use of Host Memory Buffer technology make it stand out.
