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

Samsung logoIf you need to pack more storage into your enterprise systems, then boy has Samsung got the SSD for you. The new PM1643 boasts a capacity of 30.72TB in a standard 2.5-inch drive.

On the inside, the drive has nine flash controllers driving 32 1TB packages of NAND flash, with each package containing 16 layers of 512Gb 3-bit-per-cell V-NAND. There's also 40GB of DDR4 RAM. The RAM is unusual, too; the 8Gb chips are built using Through Silicon Vias (TSVs), enabling them to be stacked vertically. They're assembled into 10 packages each of 4GB.

The drive uses a 12Gb/s Serial Attached SCSI interface. Samsung claims it can reach 400,000 read and 50,000 write random IOPS, with sequential read and write speeds of 2,100MB/s and 1,700MB/s, respectively.

Samsung rates the drive as supporting one full drive write per day over a five-year lifetime.

There's no information on price or availability just yet. Samsung says that it started making the drives in January and that it will follow the 30TB unit with 15.36TB, 7.68TB, 3.84TB, 1.92TB, 960GB, and 800GB versions.
