6Gbps, 8TB SATA SSD Doubles Capacity For Datacenters


Samsung has launched an 8TB SATA SSD for datacenter applications. The new SSD incorporates LPDDR4 DRAM modules and a 6 gigabits-per-second (Gbps) 2.5 inch SATA interface.

The PM833 aims to speed up the transition of existing data centers to SATA SSDs and leverage the advantages of advanced V-NAND technology and higher densities in data centers, Samsung said.

The PM883 includes 16Gb LPDDR4 DRAM based on advanced 10nm process technology. A SATA 3.3-compliant Power Disable (PWDIS) feature allows power management in individual SSD units to maximize the energy efficiency of tomorrow’s data centers.This is a new add-on to Samsung’s SSD’s, according to the announcement.


Samsung claims that the additional power-saving technology allows the new drive consume only 2.8W when reading, and 3.7W when writing.

The PM883 reads data sequentially at up to 550 megabits per second (MB/s) and sequentially writes at up to 520MB/s. Random reads deliver up to 98,000 IOPS and random writes up to 28,000 IOPS.

Regarding endurance, the SSD has a TBW (total bytes written) rating of 5466TB for the 3840GB drive and 10,932TB for the 7680GB drive.

Samsung is sampling the 8TB SSD to several server manufacturers. The drive will have the first form factor designed specifically for the dense 1U servers widely used in cloud data centers.
