Micron P400m 200GB Enterprise SSD Review (Page 10)

Final Thoughts


Micron is working to diversify itself from a memory-only company as they move further into the SSD market. With an increasingly diverse portfolio of consumer and enterprise storage solutions, Micron continues to push this evolution to the next level.

The most critical aspect of any storage solution is the protection of user data. Equipment failures and loss of data can result in array rebuilds and system downtime. In many cases, failures can even lead to excessive use of internal data networks as administrators clamor to restore snapshots. Data loss or equipment failure is always costly in one form or another, no matter the circumstances.

In enterprise environments reliability is the most sought after characteristic of any component, trumping overall performance in all but niche applications. These niche deployments, a very small percentage of the overall pie, are increasingly moving to utilizing PCIe application accelerators for the ultimate in performance. The majority of SSD deployments in the datacenter revolve around the traditional 2.5-inch form factor SSDs. For mainstream enterprise applications, the real focus is not king-of-the-hill specifications, but enhanced reliability, consistent performance and endurance.

The Micron P400m exhibited consistent performance and the 10DWPD of endurance provides users with a durable SSD. The low power requirements of the P400m lend itself well to managing long-term TCO. The power consumption of the P400m easily bests any HDD, and many SSDs, on the market.

One area of improvement that we would like to see is toolbox functionality for customers. Providing SMART data and drive management tools in an easy to use solution would be a value added proposition for customers. Micron captured this with the Real SSD Manager for the P320h, but as of yet does not offer this type of utility for their traditional form factor SSDs.

Micron has provided an almost bulletproof data protection solution with the combination of techniques utilized in its XPERT technology suite. Several internal mechanisms work to provide increased endurance, but Micron takes it a step further by employing their RAIN solution. This provides data redundancy at the device level, providing yet another safety net in the event of an uncorrectable error.


While RAIN does require more space to utilize its parity scheme, Micron has employed a staggering 70% overprovisioning with the P400m. Micron has integrated more techniques and IP into the SSD aimed at providing redundancy and full data path protection than many mainstream enterprise SSDs we have tested.

The Micron P400m is already qualified at major OEMs and is already available for purchase. Micron backs the P400m up with a five year warranty. While there are certainly faster options, for SATA deployments where protecting data is the top priority, we expect many to choose the Micron P400m and its brilliant XPERT technology.
