Micron introduces higher endurance SSDs

Micron Technology unveiled the M500DC SATA solid state drive (SSD) that is targeted for both mission-critical storage and cloud-based Web 2.0 storage as the company tries to grab more of the data center market share by appealing to customers who are more cost-conscious as well as those who want performance and endurance.

The M500DC, which is part of Micron’s M500 portfolio, is designed for endurance to handle transactional databases, virtualization, big data and content streaming. The M500DC SATA SSD is built on the company’s MLC NAND flash technology and custom firmware. It’s integrated with Micron’s Extended Performance and Enhanced Reliability Technology  (XPERT) feature suite, which is an architecture that integrates storage media and controller  to extend drive life to meet demanding data center workloads.

“This product casts a wide net,” said Matt Shaine,  Micron’s product marketing manager  for enterprise SSD. “Out customer use cases for this product are all over tha map in terms of capacity,  performance and endurance at an attractive price point. Our data center customers give us a lot of feedback on requirements, and they essenttially make up of two groups.”

Shaine said one group looks more at the affordable price rather than feature, performance and endurance. The other group value the mixed use of random performance, full data protection and data-path protection.

The SSD combines a 6Gbps Marvell controller with Micron’s 20-nm MLC NAND.  There are some server-type features such as die-level redundancy for physical flash failures, onboard capacitors for power-loss protection and advanced signal processing to extend the life of the NAND.

The SSD comes in both 1.8-inch and 2.5-form factors and 120, 240, 480 and 800 GBs of storage capacities. The 800 GB SSD has sequential reads of 425 MBs per second and write performance of 375 MBs per second. The 800 GB SSD has a 65,000 IOPS random read performance and write performance of 24,000 IOPs. It also has an endurance random input of 1.9 Petabytes.

The 480 SSD also has an endurance random input of 1.9 Petabytes but it has a sequential read performance of 425 MBs per second and sequential writes of 375 MBps. Its random read runs at 63, 000 IOPs and random writes at 35,000 IOPs.

Micron claims the new SSD can achieve one to three drive fills per day over five years so it reduces the need to replace drives on a frequent basis.

“This is a more rugged drive that can handle longer workloads,” Shaine said.
