Intel, Samsung intro data centre SSDs

Intel and Samsung are making a push to extend their data centre-class SSD lines with new models featuring higher performance, consistency and endurance than SSDs targeting client devices.

Intel unveiled the DC S3700 series SSDs, which are available in 100-GB, 200-GB, 400-GB and 800-GB capacity points and which feature twice the read performance and 15-times faster write performance compared to the company's previous 710 series SSDs.

Samsung last week introduced new server and enterprise storage SSDs, including a SATA model and a dual-ported SAS model.

Intel's new DC S3700 SSDs are the company's third-generation data centre SSDs after the introduction of its X25-E enterprise SSD in 2009 and its model 710 in 2011, said Roger Peene, director of data centre SSD solutions in Intel's non-volatile memory solutions group.

The SSDs that Intel labels as data centre models are those focused on performance, which Peene said includes more than just an increase in random IOs per second (IOPS).

For instance, the DC S3700 SSDs feature 15 times the write IOPS and double the read IOPS of the earlier model 710, Peene said.

"Also, they are focused on consistent performance," he said. "In laptops and desktops, consistent performance is not required. It's easy for drives to keep up with the client user. But in RAID, storage tends to operate at the performance of the slowest component, and an SSD that runs slower than expected can slow down the entire RAID performance."

Data on the DC S3700 SSDs is protected end-to-end with cyclic redundancy check (CRC) error detection, parity checks on all internal busses, error correcting code (ECC) memory and logical block address (LBA) tag protection, Peene said.

"We are working to ensure there is no silent data corruption," he said.

The DC S3700 SSDs also feature high-availability electrolytic capacitors to ensure data in flight is stored if power drops, Peene said. They are based on 25-nanometer MLC technology that allows 10 full data writes per day in order to protect the flash memory from wearing out.

The drives include a five-year warranty and are rated for 2 million hours mean time between failure (MTBF), he said.

Samsung's new SSDs

Samsung also introduced two data centre SSD models. The SM843 SATA SSD is based on MLC technology and offers 80 percent less maximum latency over the company's previous enterprise-class SSDs.

It features up to 11,000 write IOPS and 70,000 read IOPS, and it is being sampled with capacity points of 120GB, 240GB and 480GB. Power consumption is 28 percent less than previous models.

Samsung's SM1625 dual-port SAS SSDs provide up to 101,000 read IOPs and 41,000 write IOPs. It is available in 100GB, 200GB, 400GB and 800GB capacity points.
