Samsung has unveiled its two new M.2 SSDs based on PCIe NVMe protocol, the SM961 and the PM961. Both are the successors of the earlier available SM951 and the PM951 and offer much higher capacity, with up to 1TB and transfer speeds.

Based on Samsung's MLC V-NAND paired up with the new Polaris SSD controller, which is a five-core controller with eight memory channels, the SM961 will be available in 128GB, 256GB, 512GB and 1TB capacities.

Thanks to the new controller, MLC V-NAND and PCIe 3.0 x4 NVMe interface, the new SM961 SSD series will offer sequential transfer speed of up to 3,200MB/s for read and up to 1,800MB/s for write while 4K random read and write performance is set at up to 450k and 400k IOPS.

This is a significant boost compared to the SM951, which was available in capacities of up to 512GB and offer much lower sequential and random transfer speed.

In addition to the SM961, Samsung also unveiled the new PM961 SSD. The PM961 will be based on the same M.2 form-factor as the SM961, feature the same PCIe NVMe interface but comes with TLC V-NAND, paired up with the same Polaris controller.

Due to the use of the TLC NAND, the Samsung PM961 should be significantly cheaper but also offer slightly lower sequential and random performance reaching 3,000MB/s and 1,150MB/s for sequential read and write and 360k and 280k IOPS for random read and write.

In addition to these two new SSDs, Samsung also showcased its first BGA SSD, the PM971. It is soldered directly to a circuit board and uses MLC V-NAND and Photon controller. It will be available in 128, 256 and 512GB capacities and offer sequential performance of up to 1,500MB/s read and up to 600MB/s for write.

Unfortunately, there was no word on the 1TB version of the 950 Pro or any details regarding the availability date or the price.
