Samsung on Wednesday announced a pair of insanely fast M.2 solid state drives in the 960 Pro and 960 Evo during its SSD Global Summit 2016 in Seoul, South Korea.

Offered in capacities of 512GB, 1TB and 2TB, the 960 Pro delivers peak sequential read and write transfer speeds of 3,500 MB/s and 2,100 MB/s, respectively, with random read and write IOPS of up to 440,000 and 360,000. According to Samsung, that makes it the fastest M.2 NVMe SSD in the world.

Samsung tells us that the 2TB drive will come with a five-year warranty and up to 1.2 petabytes written, whichever occurs first.

The 960 Evo is no slouch, either. With Samsung’s new Intelligent TurboWrite technology, the drive is good for sequential read and write speeds of up to 3,200 MB/s and 1,900 MB/s respectively. Random read speeds top out at up to 380,000 IOPS while random writes can hit 360,000 IOPS, we’re told.

It’ll be offered in 250GB, 500GB and 1TB capacities with the largest affording a three-year warranty and up 400 terabytes written, whichever occurs first.

Both lines feature Samsung’s Dynamic Thermal Guard technology, a type of throttling that kicks in when the drives reach a certain temperature threshold. If you’re looking to get the most out of either drive, you’ll no doubt want to install it in a well-ventilated system with plenty of airflow.

The new 960 Pro and 960 Evo go on sale next month with pricing starting at $129.99 and $329.99, respectively.
