Samsung SSD SM863A 2.5 480GB

Samsung’s latest enterprise SATA SSDs are its two new lines, the PM863 and SM863. The SM863 is built all in-house at Samsung using all Samsung components. The SM863 is designed more for write intensive applications, where as the PM863 is designed more for read-intensive applications. The SM863 utilizes Samsung’s V-NAND technology giving the SSD higher density with a lower footprint. The drive comes in five capacities ranging from 120GB to 1.92TB.

Samsung first showcased its new line of SSDs back at CES in January this year. While the drives have been available for enterprises for a bit they are now also being marketing to small to medium businesses. The SM863 is ideal for applications such as mail servers, data warehousing, and high performance computing that draw more on the write side of storage. The SM863 is built for high endurance and sustained IOPS consistency. The drives also have tantalum capacitors for power loss protection making them an attractive choice for data centers where they are on 24/7 (the drive also has built-in thermal guard protection to prevent overheating). The SM863 drives have an advanced error correcting code (ECC) Engine to proactively find and correct signal discrepancies in real time. 

While the drive does come with a long list of benefits, it also makes some pretty large performance claims. The larger capacity drives claim speeds of 520 MB/s sequential read and 485 MB/s sequential write. The random performance is quoted at 97,000 IOPS read and 29,000 IOPS write. All while consuming little power and offering a reliability of 2 million hours MTBF.

The Samsung SM863 comes with a 5-year warranty and starts at $140 for the 120GB model. For our review we will be looking at the 960GB model.

Design and build

When it comes to design, Samsung knows what works for them and sticks to it. The SM863 looks very similar to the rest of the SSDs they produce. It has a minimalistic, slim design with a flat black top with Samsung branding. The bottom of the drive features a label with all the key information about the drive.

Inside the Samsung SM863 SSD, one can see the highly vertically integrated components, from the the Samsung V-NAND to the Samsung SSD controller. The heart of the drive is Samsung’s Mercury controller.

The capacity of the drive comes from eight 128GB Samsung 2bit-VNAND chips. Four on each side of the PCB.
