Samsung unveils the world largest SSD, with a capacity of over 30TB

- Adrian Ungureanu

Samsung introduced two years ago in March 2016, the largest SSD at that time, with a capacity of 15.36TB, but now they managed to double the storage capacity and announced the release of the PM1643 series.

Obviously, it is a solution best suited for industrial applications. Of course, that does not mean that if you wanted something like this, you could not buy it if you have the money.

New SSDs also offer a very high transfer speeds. Read and write speeds can reach up to 2,100MB/s and 1,700 MB/s, respectively. High speeds are achieved through the use of TSV (Trough Silicon Via) technology that uses 8GB DDR4 interconnect 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.

Complementing the SSD’s hardware ingenuity is enhanced software that supports metadata protection as well as data retention and recovery from sudden power failures, and an error correction code (ECC) algorithm to ensure high reliability and minimal storage maintenance.

Furthermore, the SSD provides a robust endurance level of one full drive write per day (DWPD), which translates into writing 30.72TB of data every day over the five-year warranty period without failure. The PM1643 also offers a mean time between failures (MTBF) of two million hours. (about 228 years).

The PM1643 series will be comprised of several SSDs of different capabilities: 800GB, 960GB, 1.92TB, 3.48TB, 7.68TB, 15.36TB and 30.72TB. The company did not announced the prices list, but certainly they will not cheap.
