Samsung crams 30TB of SSD into a single 2.5-inch drive

Samsung outdid its earlier 15.36 terabyte (TB) SSD offering from 2016 with a new 30.72TB Serial Attached SCSI (SAS) SSD, called the PM1643. In sheer storage terms, the PM1643 has enough space to hold more than 5,700 HD movies or roughly 500 days worth of non-stop video. As you can see, the company originally marketed the PM1643 SSD as a 32TB model but has since revised the total capacity, likely to accommodate overprovisioning. As long as we're talking about big numbers, the drive's 40 GB of DRAM cache is also worthy of attention.

The controller integrates nine previous controllers and has 40GB of DRAM, made from 10 x 4GB DRAM packages, which use Through-Silicon Via (TSV) tech to interconnect 8Gb DDR4 memory chips.

Police at the time said that Shigeta paid the surrogates between $9,300 and 12,500 each to carry his children. It was widely speculated that the woman might have turned against him after finding out he was gay.

Samsung reached the new capacity and performance enhancements through several technology progressions in the design of its controller, DRAM packaging, and associated software.

Announcing the new SSD in a press release, Jaesoo Han, executive vice president of Samsung's Memory Sales and Marketing Team, said: "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". The drive offers 12GBps SAS interface with read and write speeds up to 400,000 IOPS (Input/Output Operations per Second) and sequential read and write speed of 2100MBps and 1700MBps respectively. Samsung used its own SSD 850 EVO for the comparison. The company will be launching 16.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB, and 800GB versions later this year; those smaller drives should be a lot more affordable, obviously. The random read speed is nearly four times and sequential read performance is nearly thrice that of a 2.5-inch SATA drive. That's created to give better data retention and recovery rates after sudden power failures, and an error correction code (ECC) algorithm for less storage maintenance. It also includes data retention and recovery from sudden power failures, and an error correction code (ECC) algorithm. Samsung has managed to cram 30.72 TB of storage space into a 2.5-inch drive format unit, which it hopes will help accelerate the move from hard drives to solid state storage in enterprise systems. Further, according to Samsung, this SSD offers a MTBF (mean time between failures) of two million hours.
