Samsung releases super-fast SSDs

Enterprise only

Samsung has released three TCO-optimised, high-performance solid state drives which are based on 3D Vertical NAND flash memory technology.

The fastest, the PM1725, can read data at up to 5,500 megabytes per second. Other rated specs include a random read speed of up to 1,000,000 IOPS, random write performance of up to 120,000 IOPS, and sequential writes topping out at 1,800MB/s.

This makes the range faster than Intel's new SSD 750 Series NVMe PCIe solid state drive, though admittedly that's consumer product.

At 5,500MB/s (5.5GB/s), Samsung says a user can save a 5GB video file in less than three seconds. It comes in 3.2TB and 6.4TB, the latter of which can handle five drive writes per day (32TB) for five years.

Samsung tells us that that this means that users can write 6,400 files of 5GB-equivalent data or video every day.

"This represents a level of reliability quite sufficient for enterprise storage systems that have to perform ultrafast transmission of large amount of data," Samsung notes.

Samsung also introduced two other 3D V-NAND products, the PM1633 and PM953. The PM1633 is a 2.5-inch 12Gb/s SAS SSD that will be offered in 480GB, 960GB, 1.92TB, and 3.84TB capacities. Random read and write speeds are rated at up to 160,000 IOPS and 18,000 IOPS, respectively, with sequential reads topping out at 1,100MBs and sequential writes hitting a max 1,000MB/s.

The PM953 is an update to the SM951 which was the first NVMe SSD. It is available in M.2 and 2.5-inch form factors. The M.2 version will be offered in 480GB and 960GB capacities, while the 2.5-inch version will offer the same options, plus a 1.92TB capacity model.
