Samsung 15.36TB PM1633a SSD

Samsung Electronics is now shipping its solid state drive – the “PM1633a,” a 15.36 terabyte (TB) drive. The company calls it as the industry’s largest SSD.

The 1536TB SSD is based on a 12Gb/s Serial Attached SCSI (SAS) interface, for use in enterprise storage systems.

The PM1633a comes in a 2.5-inch form factor, enabling enterprise storage managers to fit twice as many of the drives in a standard 19-inch, 2U rack, compared to an equivalent 3.5-inch storage drive.

“To satisfy an increasing market need for ultra-high-capacity SAS SSDs from leading enterprise storage system manufacturers, we are directing our best efforts toward meeting our customers’ SSD requests,” said Jung-bae Lee, Senior Vice President, Memory Product Planning and Application Engineering Team, Samsung Electronics.

“We will continue to lead the industry with next-generation SSDs, using our advanced 3D V-NAND memory technology, in order to accelerate the growth of the premium memory market while delivering greater performance and efficiency to our customers.”

The SSD combines 512 of Samsung’s 256Gb V-NAND memory chips. The 256Gb dies are stacked in 16 layers to form a single 512GB package, with a total of 32 NAND flash packages in the 15.36TB drive.

It uses Samsung’s 3rd generation, 256-gigabit (Gb) V-NAND technology which stacks cell-arrays in 48 layers, the PM1633a line-up. Its predecessor, the PM1633, which used Samsung’s 2nd generation, 32-layer, 128Gb V-NAND memory.

The 15.36TB PM1633a drive supports 1 DWPD (drive writes per day), which means 15.36TB of data can be written every day on this single drive without failure.

Starting with the 15.36TB density, Samsung said it will provide a wide range of capacity options in its PM1633a SSD line-up – 7.68TB, 3.84TB, 1.92TB, 960-gigabyte (GB) and 480GB later this year.
