Samsung has launched its largest SSD up to date, the PM1633a 15.36TB SSD for Enterprise Storage Systems, which will be based on Samsung's 3rd generation 256Gb V-NAND.

Revealed earlier during the 2015 Flash Memory Summit in August last year, the Samsung PM1633a is based on a standard 2.5-inch form factor and features 12Gbps Serial Attached SCSI (SAS) interface.

The Samsung PM1633a is based on 512 Samsung 256Gb V-NAND flash chips. The 256Gb dies are stacked in 16 layers to form a single 512GB package. This adds up to a total of 32 NAND packages on the 15.36TB model. According to Samsung, the 3rd generation 256Gb V-NAND will provide significant performance and reliability improvements compared to the PM1633 drive which used 2nd generation 32-layer 128Gb V-NAND flash.

According to Samsung, enterprise managers can now fit twice as many drives in a standard 19-inch 2U rack compared to a 3.5-inch storage drive.

When it comes to performance, the Samsung PM1633a provides sequential read and write performance of up to 1,200MB/s with random read and write of up to 200,000 IOPS and 32,000 IOPS, respectively. The 256Gb V-NAND flash, 16GB of DRAM cache and 12Gbps SAS interface are controlled by Samsung's new controller with specially designed firmware that can access large amounts of high-density NAND.

The new Samsung PM1633a enterprise SSD also offers high high reliability date with 1DWPD (drive writes per day), adding up to 15.36TB that can be written every day without failure. The high reliability is quite important in the enterprise market.

The Samsung P1633a will be available in wide range of capacities, including 480GB, 960GB, 1.92TB, 3.84TB, 7.68TB and the aforementioned 15.36TB version.

Unfortunately, Samsung did not reveal any details regarding the price but did note that the 15.36TB version should be available soon while the rest of the lineup should follow later this year.
