Samsung Electronics has been a leader in the electronics industry for more than 30 years. Since the introduction of their first television in 1970, this Korean company has grown to become one of the world's leading electronics manufacturers, offering everything from tiny semiconductors to large home appliances. Samsung is no stranger to the storage industry either. Along with an assortment of DVD and Blu-ray Disc drives, the company offers both hard drive and flash based storage solutions for the portable and desktop computer markets

Like many other manufacturers, Samsung has set its sights on the growing solid-state drive (SSD) market. This past fall, the company introduced two new drives, the SSD 840 and SSD 840 Pro. Designed and built completely in-house, these two ultra-slim SSDs are powered by Samsung's own triple-core MDX controller and feature a SATA 6GB/s interface, specially-engineered wear-leveling and garbage collection algorithms and up to 512MB of cache. From here though, the similarities end. Where the SSD 840 is aimed at the cost conscious consumer, the high-performance SSD 840 Pro is equipped with Samsung's Toggle DDR2 NAND flash memory to deliver up to 540MB/s read and 520MB/s write speeds as well as a maximum of 100,000 IOPS.

For this review, we purchased the 256GB version of the SSD 840 Pro. This drive is capable of delivering up to 540MB/s sequential read and 520MB/s sequential write speeds as well as up to 100,000 random read and 90,000 random write IOPS.
