The RealSSD P400m from Micron is a SATA III SSD aimed to provide storage solutions to enterprise workstations. This solid state drive is available in capacities of 100GB, 200GB and 400GB. The RealSSD P400m is capable of reaching a maximum sequential read speed of 380 MB/s and a maximum sequential write speed of 310 MB/s. Consequently, maximum IOPS numbers are listed at 60,000 and 26,000 for random read and write respectively.
A special type of NAND is used on the RealSSD P400m, giving it an endurance of 0.0175 PB per GB capacity. The NAND modules are handled by Marvell’s 88S9187, the same one used on the Plextor M5P. The drive features secure erase command set and SMART monitoring, among others. The Micron RealSSD P400m has a Mean Time to Failure (MTTF) of 2,000,000 device hours and comes with a limited warranty of five years.

Micron’s high endurance MLC NAND and custom controller firmware are the defining features of the P400m. These features combine to make the P400m excel at write endurance and performance consistency.
The Micron RealSSD P400m offers very consistent performance, regardless of data type, and remains competitive at higher queue depths.
Compared to its past efforts, Micron arms the P400m with a lot of new technology and decidedly better performance.
