Recently Samsung Introduced new high performance SATA SSDs aimed at small to medium businesses, 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, upto 3.8TB. This will give data centers better performance at a higher density while bringing down the overall footprint.

Samsung SM863 AND PM863

The Samsung PM863 is a 3-bit per cell (TLC) drive that can handle up to 3.8TB of storage in a single 2.5″ SSD. This is an example of the smaller SSD form factor getting competitive with rotating media in terms of storage density. Being a TLC drive, we would expect fairly competitive pricing. We have seen rough MSRP of £1409 ($2199) on the 3.8TB drive.

The Samsung SM863 is a higher-end offering using 2-bit per cell technology. The capacity is only 1.9TB for each drive which is about half of the PM863. We would expect the combination of MLC plus 3D V-NAND to yield significant improvements in terms of latency and endurance over the PM863. Since Samsung recently announced the 2TB 850 Pro, we would expect these drives to have a similar amount of NAND with more overprovisioning which is standard on datacenter SSDs. The MSRP of the SM863 1.92TB drive is £800 ($1249) with the PM863 of the same capacity selling for £704 ($1099.)
