Unveiled just in time for testing was the Micron M500DC, an endurance-optimized SSD for the data center that the company says can endure as many as three complete fills every day for five years. The unit is available in capacities of 120, 240, 480 and 800 GB and in 2.5-inch and 1.8-inch form factors. It's rated to deliver 425 MEGs for reads and up to 375 for writes, depending on drive size and capacity. Over USB, the 480pGB drive peaked at 36.4 MEGs for reads and 31.1 MEGs for writes.

Overall the Micron M500DC is a great performing, all around drive that finally gives Micron a solution that bridges the gap between consumer and traditional enterprise grade hardware. With the hyperscale datacenter becoming a rapidly growing market, the M500DC is in the perfect position to meet the needs of datacenters who require enterprise grade reliability, consistency and power loss protection, but aren’t looking to pay traditional enterprise grade prices.

Delivering outstanding performance that rivals even leading 6Gb/s mission-critical SATA SSDs in random write workloads at an outstanding price point is a stellar achievement. … For those in the hunt for solid performance, the M500DC delivers leading performance in the value segment. Micron has lifted the bar in the mixed-use value class SSD arena, meriting the TweakTown Editor's Choice Award.

Overall the M500DC is a sensible addition to Micron's enterprise SSD lineup. It fills the gap between the consumer M500 and the P400m by providing a solution that is affordable yet has the feature set and meets the performance requirements of enterprise customers. The performance is actually far better than I expected from an entry-level drive…
I believe the M500DC provides a well balanced solution for the hyperscale customers that require consistent performance but are not looking for extreme endurance. The hyperscale market is quickly growing and will continue to do so and more affordable enterprise SSDs with regular MLC will continue to aid that growth.

Random write performance is on par with drives that are twice the price. This benefited most of our mixed workload tests, especially our database profile, where the M500DC was incredibly quick. It’s not just raw speed that impressed us, it was also consistency. While not the most consistent drive we have ever tested, it far surpassed SSDs in a similar price range. At 2 drive writes per day (DWPD), the M500DC is also suited for more write intensive applications. Throw in Micron’s impressive list of enterprise features, 2M hour MTBF and 5 year warranty, and you can feel confident that your data is safe.

Micron doesn’t disclose pricing on its enterprise-class drives, but we were told the Micron M500DC series will be "priced competitively versus drives targeting the same market segment" and that they’ll be available immediately. Assuming that holds true, the new Micron M500DC series should be excellent offering in solid state storage. The drives perform well across a variety of workloads, they offer enterprise-class data path protection, and leverage Micron’s XPERT features. They’re also outfitted with power loss protection, and are built with high endurance in mind. These new SSDs will also be offered in both 1.8” and 2.5” flavors. Sequential transfers weren’t quite as high as some competing drives in their category, but overall there aren't many compromises with this new breed of Micron drives. The M500DC series is yet another strong family of products to come out of Micron.

The M500DC Enterprise SSD combines Micron's expertise in NAND engineering and manufacturing, Marvell controllers, and the Micron XPERT technology stack. The M500DC targets the light-enterprise use case which generally consists of server boot duty, read-centric activities like media streaming or other application use that is generally read intensive. Deployments of the M500DC also get an array of enterprise features, like power fail protection, that aren't found in the low cost client drives that often creep into this space… When it comes to living up to Micron's performance claims, the M500DC has no trouble matching the rated synthetic results that Micron advertises…The Micron drive is also expected to be less expensive than some of the competition the light enterprise space, so depending on cost, the M500DC may see a solid IOPS/$ benefit too.
