Bottom Line:

The Western Digital NVMe/PCIe client architecture that is built into this SN720 unit enables manufacturers of IoT devices, computing devices, embedded PCs and servers to capture and transform massive quantities of data in real-time. The unit is well suited to applications that require both high performance and low power.

The SN720 lacks the total storage capacity of solutions such as the Micron 5200, the Toshiba XD5 or the Samsung 883. But for those looking for lightning fast speed fore relatively small workloads, this unit very much fits the bill.

Product Description:

The Western Digital SN720 is a PCIe SSD that is available in 256 GB, 512 GB, 1 TB, and 2 TB capacities on a single-sided M.2 2280 form factor. It delivers high performance with sequential read/write speeds of up to 3,400MB/s and 2,800MB/s. Its new NVMe SSD firmware and controller architecture is purpose-built to maximize performance and scalability benefits of 3D NAND for low latency and power efficiency.

The WD SN720 is a compact storage device with high capacity. Supporting PCIe Gen3 x4, it is designed for high intensity applications such as Ultra HD video, 4K video, VR content creation, post production processing, high-bandwidth corporate computing, software development and compilation. 64-layer 3D NAND provides longevity. Its tiered-caching NVMe architecture delivers extreme performance and endurance of up to 500 TBW.
