Patriot Memory's gaming brand, Viper Gaming, today announced the VP4300 series M.2 NVMe SSDs that take advantage of the PCI-Express 4.0 x4 bus. The drives combine Innogrit IG5236 controllers with 3D TLC NAND flash memory, and come in 1 TB and 2 TB capacity variants. On offer are sequential transfer rates of up to 7400 MB/s sequential reads, with up to 6800 MB/s writes for the 2 TB variant, and up to 5500 MB/s writes for the 1 TB variant; along with 4K random access performance of up to 800,000 IOPS.

The Viper VP4300 comes with two thermal solutions in the box. You can choose to run it bare (in notebooks, where it might thermal-throttle); with a thin copper heatspreader that uses a graphene-based thermal pad, or a slightly thicker aluminium heatsink. The drives are backed by 5-year warranties.

Update Apr 16th: Patriot reports that the 1 TB version will be priced at USD $254.99, and the 2 TB version at $499.99.
