South Korean tech giant Samsung has announced that it has begun mass producing, what the company is claiming to be, the industry’s largest capacity Serial Attached SCSI (SAS) solid state drive (SSD) – the PM1643.
As per Samsung's blog, this drive is based on Samsung’s V-NAND technology with 64-layer and 3-bit 512-gigabit (Gb) chips and offers the drive offers 30.72 terabyte (TB), twice the capacity and performance of the previous 15.36TB high-capacity line-up introduced in March 2016.
The latest model is targeted at a host of market segments, , including the government, financial services, healthcare, education, oil & gas, pharmaceutical, social media, business services, retail and communications sectors.
This drive combines 32 of the 1TB NAND flash packages. Each of them comprises of 16 stacked layers of 512Gb V-NAND chips.
These 1TB packages are claimed to allow 5,700 5GB full HD movie files.
The storage device measures 2.5-inch, the PM1643 drive has read speed of up to 400,000 Input/output operations per second and write speed of 50,000 IOPS and sequential read and write speeds of up to 2,100MB/s and 1,700 MB/s, respectively.
The PM1643 is claimed to be first to have TSV-applied DRAM used in an SSD. Through Silicon Via (TSV) technology interconnects 8Gb DDR4 chips that creates 10 4GB TSV DRAM packages, totalling 40GB of DRAM. The SSD claims to be able to sustain full drive write per day (DWPD), which is approximately 30.72TB of data every day over the five-year warranty period.
“With our launch of the 30.72TB SSD, we are once again shattering the enterprise storage capacity barrier, and in the process, opening up new horizons for ultra-high capacity storage systems worldwide,” said Jaesoo Han, executive vice president, Memory Sales & Marketing Team at Samsung Electronics. “Samsung will continue to move aggressively in meeting the shifting demand toward SSDs over 10TB and at the same time, accelerating adoption of our trail-blazing storage solutions in a new age of enterprise systems.”
