Samsung Electronics recently made an announcement regarding the shipping of the industry’s highest-capacity solid-state drive (SSD), the 15.36TB PM1633a. Last August, the company also revealed that they were working on the drive that would use the same form factor as for a laptop computer: 2.5-in.
The 2.5-in SSD is based on a 12Gbps Serial Attached SCSI (SAS) interface for use in enterprise storage systems. The PM1633a has blazing fast performance, with random read and write speeds of up to 200,000 and 32,000 I/Os per second (IOPS), respectively. It delivers sequential read and write speeds of up to 1200MBps, the company said. A typical SATA SSD can peak at about 550MBps.
A per Samsung, Because the PM1633a comes in a 2.5-in. form factor, IT managers can fit twice as many of the drives in a standard 19-in. 2U (3.5-in.) rack, compared to an equivalent 3.5-in. storage drive. The SSD also sets a new bar for sustainability. The 15.36TB PM1633a drive supports one full drive write per day, which means 15.36TB of data can be written every day on a single drive without failure.
The SSD can write from two to 10 times as much data as typical SATA SSDs based on planar MLC and TLC NAND flash technologies. Samsung said it is betting on the PM1633a SSD line-up to “rapidly become” the overwhelming favorite over hard disks for enterprise storage systems.
Jung-bae Lee, senior vice president of Samsung Electronic’s Application Engineering Team, in a statement said “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. The performance of the PM1633a SSD is based on four factors: the 3D NAND (vertical NAND or V-NAND) chips; 16GB of DRAM; Samsung’s proprietary controller chip; and the 12Gbps SAS interface.”
The random read IOPS performance is about 1,000 times that of SAS-type hard disk drives and the sequential read and write speeds are more than twice the speed of a typical SATA SSD, the company said.
