Samsung introduces its new solid-state drive with SAS interface

While Samsung Electronics is one of the leading suppliers of consumer-oriented solid state drives, the company is not really known for its enterprise-class offerings simply because its portfolio of such drives is not really large. On Thursday Samsung introduced its new-generation SM1623 solid-state drive that features Serial Attaches SCSI (SAS) interface and is aimed at enterprise customers.

The Samsung SM1623 is set to be available in capacities up to 800GB and is based on Samsung’s NAND flash memory made using “10nm-class” (most likely 19nm) process technology. Sequential read and write speeds of the SM1623 are up to 950MB/s and 520MB/s, respectively, which is in line with its predecessor, the Samsung SM1625 introduced about two years ago. The SM1623 delivers random read and write speeds of up to 120K and 26K IOPS [input/output operations per second], respectively, which is also similar to its predecessor.

The main advantage of the new SM1623 compared to the SM1625 is its lower power consumption thanks to new NAND flash. Unfortunately, the thinner process technology used to make memory also means that endurance of the SM1623 will be lower compared to the SM1625. The new drive sustains “more than a drive write per day” (DWPD) for five years, whereas the old drive supported up to 10 DWPD for a period of five years.

“With our new SAS SSD, our competitiveness in the enterprise storage SSD market has been strengthened,” said Jeeho Baek, vice president, memory marketing at Samsung Electronics. “We are committed to providing storage customers with an exceptionally wide variety of next-generation, high-capacity SSDs in driving the fast-growing enterprise storage SSD market.”

Samsung’s enterprise SSD portfolio includes NVMe (non-volatile memory express) drives with PCI Express interface, SATA solutions as well as SAS drives.

So far no major enterprise software developer has certified the SM1623.

KitGuru Says: Looks like the Samsung SM1623 is a lower-power and a more affordable version of the SM1625, so no real performance improvements here.
