Kicking off with its latest SAS-based SSD, the new PM1633 is "designed to meet all requirements of Serial Attached SCSI (SAS) interface based systems". The PM1633 is based on the 2.5-inch form factor and the 12Gbps SAS standard, and will arrive in 480GB, 960GB, 1.92TB and 3.84TB versions. Samsung's PM1633 is capable of random read and write speeds of up to 160,000 and 18,000 IOPS, respectively. When it comes to sequential read and writes, we can expect 1.1GB/sec and 1GB/sec, respectively.

Moving onto the new half-height, half-length (HHHL) card-type, NVMe-based SSD - the new PM1725 - offers huge speeds, and massive capacities of 3.2TB and 6.4TB. The PM1725 is capable of random read speeds of up to 1 million IOPS, while writes hit 120,000. It can read at a huge 5.5GB/sec while it writes at 1.8GB/sec, with Samsung teasing that it can enable "users to save a 5GB video in less than three seconds".

Lastly, Samsung has updated the industry's first NVMe-based SSD, the SM951, with a new M.2-based form factor. The new PM953 arrives in the NVMe interface, and is available in both the 2.5-inch and M.2 standards. Samsung's updated PM953 is the ideal solution for large-scale data centers, mobile workstations and ultra-slim notebook PCs and high-end desktop PCs. The M.2 version of the PM953 will be made in 480GB and 960GB versions, while the 2.5-inch version will be offered in 480GB, 960GB and 1.92TB capacities.
