Samsung Ships First 15TB SSD

Samsung ships the world's largest storage SSD drive.

Samsung ships now a SSD drive with 15GB storage, which is the largest capacity SSD drive on the market. The Samsung PM1633 has 15.36 terabyte (TB) of storage.

First introduced at the 2015 Flash Memory Summit in August, the 15.36TB SSD is based on a 12Gb/s Serial Attached SCSI (SAS) interface, for use in enterprise storage systems. Because the PM1633a comes in a 2.5-inch form factor, enterprise storage managers can 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 Samsung SSD drives' 15.36TB of data storage on a single SSD is enabled by combining 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. Utilizing Samsung’s 3rd generation, 256-gigabit (Gb) V-NAND technology which stacks cell-arrays in 48 layers, the PM1633a line-up provides significant performance and reliability upgrades from its predecessor, the PM1633, which used Samsung’s 2nd generation, 32-layer, 128Gb V-NAND memory.

The PM1633a SSD sports random read and write speeds of up to 200,000 and 32,000 IOPS respectively, and delivers sequential read and write speeds of up to 1,200MB/s. The random read IOPS performance is approximately 1,000 times that of SAS-type hard disks, while the sequential read and write speeds are over twice those of a typical SATA SSD. Inside the new SSD lie Samsung’s advanced controller units that support the 12Gb/s SAS interface, along with a total of 16GB of DRAM. Samsung also uses specially designed firmware that can access large amounts of high-density NAND flash concurrently.

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, a level of reliability that will improve cost of ownership for enterprise storage systems. This drive can write from two to ten times as much data as typical SATA SSDs based on planar MLC and TLC NAND flash technologies.

Further, the drive boasts a highly dependable metadata protection mechanism in addition to featuring a data protection and restoration software tool in case of a momentary blackout, which make enterprise systems more stable and manageable.

Starting with the 15.36TB density, Samsung 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. With more choices in storage capacity, Samsung is reinforcing the competitiveness in its SAS SSD line-up. 

Yesterday Samsung started to ship the Samsung SSD T3, a portable SSD drive with up to 2TB storage.
