Samsung starts production of SSDs with a whopping 30.72TB storage capacity

The Korean company has begun production of a massive 30.72 Terabyte (TB) solid state drive called the PM1643, it announced on Tuesday.

Samsung's PM1643 is not a consumer-focused device.

All of that storage is enough for 5,700 full HD movies at 5GB apice, the company says.

North Korea 'fully ready for both dialogue and war,' state media says
It's unclear whether Trump will meet Kim Yo Jong - who has been dubbed "the Ivanka Trump of North Korea " - during her visit. In April 2015, South Korea's spy agency claimed she would likely give birth to a child the following month.

Samsung tells us that the PM1643 has almost twice the performance of its PM1633a, and around four times the random read and three times the sequential read performance of its 850 EVO consumer SSD. The device has more than twice the capacity of the largest disk drives, and 24 of these stuffed into a 2U, 24-slot enclosure would produce a 737.3TB, 0.74PB device - impressive, and needing some kind of protection to limit the so-called blast radius if one of the drives failed. Their new highly efficient controller architecture integrates nine controllers (from their previous high-capacity SSD lineup) into a single package, allowing for a greater amount of space within the SSD for storage. This marks the first time that TSV-applied DRAM has been used in an SSD. The new drive also incorporates the TSV (Through Silicon Via) technology that interconnects 8Gb DDR4 chips creating up to 10 units of 4GB TSV DRAM units, with a total of 40GB of DRAM. "Managing all the DRAM and flash with a single controller is almost impossible within the required thermal envelope of a 2.5" device, so Samsung spread the task out among nine different controllers.

Not only that, but the drives are based on a 12Gb/s Serial Attached SCSI (SAS) interface, which is 2x the max capabilities of your typical SATA formats of SSD. This SSD is built on the latest V-NAND technology with 64-layer, 3-bit 512-gigabit (Gb) chips. By way of comparison, the aforementioned 860 EVO tops out at a 4TB model, so there's still a mountain to climb before such Herculean capacities trickle down to the High Street. For specific numbers, this SSD has sequential read/write speeds of up to 2,100MB/s and 1,700MB/s respectively.

Along with being big and fast, the world's largest SSD is robust as well. Samsung is also offering a five-year warranty. Mean time between failures is two million hours.

The payment to McDougal by American Media was originally reported by the Wall Street Journal on November 4, 2016. McDougal also described complex legal and financial agreements that were used in an alleged bid to cover it up.

When exactly the new PM1643 will arrive in the market isn't known, but Samsung plans to expand its range of SAS SSDs later this year, with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB and 800GB versions. Dubbed Samsung PM1643, the new ultra-high capacity SSD packs the most storage ever in a 2.5-inch form factor.

There's no word on exact launch date or price, but we reckon it won't be particularly cheap.
