Western Digital has announced increased capacities of its SN720 and SN520 NVMe, M.2 format SSD drives.

The 1TB SN720 is capable of a blistering 3400/2800MB/s sequential read/write and 500/400 IOPS random read/write and up to 400TBW (Terabytes Written).

The NVMe Gen3 X4 drive is also available in 256 and 512GB capacities in the standard M.2 2880 format. A 2TB drive is coming soon.

The 512GB SN520 is capable of 1,700/1400MB/s sequential read/write and 270/280 IOPSA random read-write and 300TBW.

This NVMe Gen3 X2 drive is also available in 128 and 256GB capacities in M.2 2230, 2242 and 2280 formats. These are handy for OEMs building different format devices.

NVMe speeds are several times faster than SATA SSD and use less power. They use the new 64-layer, 3D NAND and caching systems to protect data integrity. Drives have a 5-year limited warranty.

“Performance demands on PCs continue to increase, thanks to new applications like VR and AI, as well as the growing requirements for gaming, 4K editing and more,” said Bob O’Donnell, President of TECHnalysis Research.

“This is driving PC makers to ensure that their storage subsystems can meet these expanded requirements with technologies like NVMe and high-speed flash SSDs. We also see similar storage demands in other fields, including IoT applications in manufacturing, medical, video surveillance and more.”

The groundbreaking new NVMe SSD firmware and controller architecture is purpose-built to maximise the performance and scalability benefits of Western Digital 3D NAND and is in lock-step with the company’s NAND evolution.

“With this new vertically integrated SSD platform, we can optimise the architecture to our NAND for low latency and power efficiency, and most important, for the growing range of applications benefiting from NVMe,” said Eyal Bek, Senior Director of Client SSD, Devices Business Unit, Western Digital.

“The scalable architecture supports a range of capacity and performance points while streamlining system qualification to improve time-to-market for our customers.”
