Samsung kicked off the volume production of the 30.72 TB SSD called PM1643, the SSD with a larger 12 Gbps SAS interface built up to now. Let’s talk about a drive aimed and optimized for enterprise environments, based on the Samsung’s latest V-NAND technology with 64-layer, 3-bit 512-gigabit (Gb) chips.
To achieve this capacity, the manufacturer used 32 of the new 1TB NAND flash packages, each comprised of 16 stacked layers of 512Gb V-NAND chips. Samsung doubles the capacity compared to the previous generation model of 15.36 TB, was introduced in 2016, also significantly improving sequential and random performance. But that is not all.
In fact, according to data released by the company, the Samsung PM1643 SSD offers read and write speeds of up to 2,100MB/s and 1,700 MB/s, respectively. While the random read and write speeds of up to 400,000 IOPS and 50,000 IOPS.
The PM1643 drive also applies Through Silicon Via (TSV) technology to interconnect 8Gb DDR4 chips, creating 10 4GB TSV DRAM packages, totaling 40GB of DRAM. This marks the first time that TSV-applied DRAM has been used in an SSD.
The Samsung PM1643 is equipped with all the options to security and integrity of data; as regards endurance, on the other hand, the manufacturer declares a value of 1 DWPD for 5 years with MTBF equal to 2 million hours.
As of now, there are no details on the price. However, Samsung started manufacturing initial quantities of the 30.72TB SSDs in January and plans to expand the lineup later this year – with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions.
