Samsung Electronics Co., Ltd., the world
leader in advanced memory technology, announced today that it is now shipping
the industry’s largest solid state drive (SSD) – the “PM1633a,” a 15.36 terabyte (TB)
drive.
First revealed 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 unprecedented 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.
Samsung’s new PM1633a SSD provides the
opportunity for significant improvements in the efficiency of IT system
investments through its high storage capacity and exceptional performance.
These performance gains stem from Samsung’s latest vertical NAND (V-NAND) flash
technology, as well as the company’s proprietary controller and firmware
technology.
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. The Samsung PM1633a
SSD line-up is expected to rapidly become the overwhelming favorite over hard
disks for enterprise storage systems.
