Samsung Unveils World's Largest 2.5-inch SSD With 30.72TB of Storage

Although it of course won't move at these speeds, it does feature sequential read and write speeds of up to 2,100MB/s and 1,700 MB/s (random read and write speeds of up to 400,000 IOPS and 50,000 IOPS), matching it to speeds similar to NVMe SSD options and so much quicker than SATA. Let's hope that Samsung will soon officially launch this SSD.

Toshiba introduced its 31TB PM5 SSD in August past year, so Samsung, with the PM1643 in manufacturing is now on a par with Toshiba.

Samsung is not just about smartphones, and the Korean company has proven it once again by coming up with the world's largest SSD (solid state drive). It previously held the crown as the biggest SAS SSD on the market. That's impressive random read performance, but random writes are somewhat slower than some competing SSDs.

Samsung has today unveiled a new line of SSDs for enterprise systems that doubles its previous world's largest capacity. It plans to add SSDs with capacities ranging from 800 GB to 15.36 TB to the lineup in a bid to ease the transition from HDDs to SSDs. It also has 960 and 800GB models planned.

The PM1643 is built out of 32 sticks of 1TB NAND flash packages all joined together, with each stick containing 16 layers of 512GB V-NAND chips. This is an enterprise 2.5-inch solid-state drive with a Serial Attached SCSI (SAS) interface.

As with any fast SSD, the PM1643 comes with plenty of DRAM to help speed up internal operations. "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. 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. Dubbed Samsung PM1643, the new ultra-high capacity SSD packs the most storage ever in a 2.5-inch form factor. It also includes data retention and recovery from sudden power failures, and an error correction code (ECC) algorithm.

Samsung credits a 30TB capacity drive to several advancements. These drives are destined for OEM systems, so pricing likely hinges on volume purchasing agreements. Samsung says the stacked DRAM lets it give over more of the drive's volume to NAND.
