Worlds largest SSD with 30.72TB capacity

  • Samsung Electronics has revealed the world’s largest capacity Serial Attached SCSI(SAS) SSD with a mind-boggling capacity of 30.72TB- packed in just a 2.5-inch form factor.
  • The new drive also features a 40GB DRAM, an upgraded and more efficient drive controller and associated software.
  • The capacity of the drive is attributed to 32 NAND Flash packages combined together. Each one of these 32 packages is made from 16 layers of 512 GB V-NAND chips.
  • It is worth mentioning that Samsung unveiled a 15.36 TB SSD in March 2016 and the new PM1643 is exactly double of that capacity while retaining its size.
  • The new solid-state drive is not only a capacity upgrade. It features lightning-fast data transfer speeds as well. When compared to the previous generation SAS SSDs, the new drive delivered nearly twice the performance.
  • Sequential read and write speeds of up to 2100 MBPS and 1700 MBPS respectively were recorded in tests done by Samsung.
  • The random read speed is almost four times and sequential read performance is almost thrice that of a 2.5-inch SATA drive. Samsung used its own SSD 850 EVO for the comparison.
  • An enhanced software compliments the SSDs hardware and provides features such as metadata protection, data retention and recovery in case of sudden power losses, Samsung informed.
  • An error correction code algorithm is incorporated to ensure reliability and minimal storage maintenance.
  • The drive is designed to endure heavy workloads and can survive one full drive write per day (DWPD), which is equivalents writing 30.72TB data into the drive daily for the 5-year warranty period, which seems to be quite a bold claim.
