The Samsung 256GB 840 pro SSD is one of the newest storage devices in the Samsung lineup. With this revision Samsung has included their triple-core MDX controller into the 840 line. The three cores allow the 840 and 840 pro drives to execute multiple instructions at a time improving performance under heavy use. Using a SATA 3.0 6GB/sec interface the Samsung 840 Pro is rated for 540MB/sec sequential read, 450MB/sec sequential write speeds, 100,000 IOPS in random read, and 90,000 IOPS in random write speed. All while using a minimal amount of power at an average of only .068 watts during active use and .042 watts in idle power. Samsung also includes their Samsung Smart Data Migration Software in the package to assist in the transition and Samsung Magician 4.x to assist with monitoring and maintaining the health of the drive, along with a 5 year warranty.
