The Micron P400m is an enterprise SSD engineered for use in servers, appliances and storage platforms. The P400m uses a mainstream 7mm 2.5 form factor, SATA interface and Micron's 25nm MLC NAND. Like the P300 this drive replaces, the P400m uses a Marvell drive controller with customized Micron firmware on top that has been tuned for performance under even read and write usage scenarios. From a performance perspective, the P400m delivers 64KB sequential reads and writes of 380MB/s and 310MB/s respectively, with 4KB random read and write IOPS of up to 60,000 and 26,000. Beyond peak performance, the P400m includes Micron's XPERT (extended performance and enhanced reliability technologies) portfolio to deliver on the features enterprise customers care about most: endurance, data protection, consistent performance, low latency and low power consumption. These features are largely personified by the P400m's firmware and drive architecture, which is developed by Micron in-house with Micron NAND. The advantages of having an internal development team who can coordinate with NAND architects are evident in terms of drive features, but also in harder to define ways like compatibility and drive reliability. Micron also includes capacitors with the P400m, which protects data in-flight during an unexpected loss of power.
