Samsung Announces 8TB SATA Enterprise SSD

Samsung has announced the rollout of the PM883, its highest-density datacenter SATA drive at 8TB. PM883 is the first datacenter SATA drive to use LPDDR4 DRAM (16Gb) packages while featuring a 6.0Gbps, 2.5-inch SATA interface. Samsung indicates that it will accelerate a transition in many existing enterprise datacenters to SATA-formatted SSD designs, boasting enhanced economies of scale through the use of advanced-generation V-NAND technology at higher densities.

The PM883 is also the first SSD that supports a SATA 3.3-compliant Power Disable (PWDIS) feature, which allows power management in individual SSD units to maximize the energy efficiency of tomorrow’s datacenters. As a result, the new Samsung drive is quoted to use just 2.8 watts of power in reads and 3.7 watts in writes.

As for performance, the PM883 is set to deliver sequential reads and writes at 550MB/s and 520MB/s, respectively.  Random speeds are expected to hit upwards of 98,000 IOPS and 28,000 IOPS in reads and writes, respectively. The TBW rating is specced at 5,466TB for the 3840GB drive and 10,932TB for the 7680GB drive.

Samsung also announced that it will exhibit two new HPC memory solutions at the 2018 Open Compute Project U.S. Summit in the San Jose: the Samsung NF1, which is the first 8TB SSD built in the ultra-small NF1 form factor, and the first 64GB DDR4 RDIMM using 16Gb monolithic chips. The Samsung NF1 64-layer 8TB SSD was designed to dramatically improve the storage capacity and performance of next-generation 1U rack servers and is quoted to deliver I/O at a phenomenal 0.5 petabytes per second. Samsung’s 16Gb-based 64GB RDIMMs are low-power monolithic chips that support interface speeds of 2666 MT/s. They will offer a greater than 20% power reduction versus 8Gb-based 64GB LRDIMMs and allow the maximum DIMM density to increase to 256GB. Samsung believes that this will make them well-suited for memory-intensive applications such as In-Memory Databases and VDI.

Samsung is expected to expand its lineup with higher capacity 16Gb-based 128GB and 256GB RDIMM and LRDIMMs sometime later this year. The 16Gb 64GB DDR4 RDIMMs are available now.
