Samsung Unveils SM863 & PM863 Data Center SSDs

Today Samsung Electronics Co., Ltd. Introduced new high performance SATA SSDs aimed at small to medium businesses (SMB), the SM863 and the PM863. First showcased as CES earlier this year, Samsung states that the new SSDs will deliver higher reliability, faster speeds, and much higher capacities. This will give data centers better performance at a higher density while bringing down the overall footprint.

Both drives are 2.5” form factor and powered by Samsung’s V-NAND technology. The PM863 uses 3-bit MLC V-NAND making it ideal for mixed pattern applications such as content delivery networks and streaming or Web servers. While the SM863 uses 2-bit MLC V-NAND making it ideal for online transaction processing (OLTP) such as email and database servers.

The smaller form factor adds to the higher density but these new drives also come in much higher capacities, up to 3.8TB for the PM863. The PM863 comes in capacities 120GB, 240GB, 480GB, 960GB, 1.9TB, and 3.8TB and the SM863 comes in capacities of 120GB, 240GB, 480GB, 960GB, and 1.9TB. Both of the new drives also claim some decent performance numbers with the PM863 having read speeds of 540MB/s and random read speeds of 99K IOPS for the 240GB and above drives. The SM863 claims read speeds of 520MB/s and write speeds of 485MB/s.


Both the SM863 and PM863 are already available for enterprise businesses and are expected to be available for SMB in August 2015.
