Samsung has launched a trio of TCO-optimized solid state drives based on the company's three-dimensional (3D) Vertical NAND (V-NAND) flash technology.

As an update to the SM951, the PM953 will be available in both M.2 and 2.5-inch form factors. The former is offered in your choice of 480GB or 960GB capacities while the 2.5-incher can be had with 480GB, 960GB or 1.92TB of storage.

The PM1633, meanwhile, is Samsung's latest SAS SSD. It's a 2.5-inch 12GB/sec drive that's offered in capacities of 480GB, 960GB, 1.92TB and 3.84TB. Samsung says the drive is capable of delivering random read and write speeds of up to 160,000 and 18,000 IOPS respectively and boasts sequential read and write speeds of up to 1,100MB/s and 1,000MB/s.

Last but certainly not least is the PM1725, a half-height, half-length (HHHL) card-type NVMe drive that's available with 3.2TB or a colossal 6.4TB of storage. The drive provides random read speeds of up to 1,000,000 IOPS and writes randomly at up to 120,000 IOPS. It also sequentially reads at up to 5,500 MB/sec and writes sequentially at up to 1,800MB/s.

If you know a thing or two about drive speeds, you can appreciate just how fast the PM1725 is.

Drives are available for purchase as of writing although they're primarily being marketed to OEMs / enterprise users.
