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. Last summer, the company launched the 840 EVO. Unveiled at Samsung's annual SSD Global Summit, the drive was powered by the company's 3-core MEX controller and offered up to 1TB of the their second generation 3-bit/cell MLC NAND. To overcome the slow write speeds typically associated with this type of NAND flash, Samsung increased the size of the DRAM cache and implemented an innovative write acceleration algorithm called TurboWrite, which creates a high-performance write buffer in the SSD. The 840 EVO was also the first drive to support Samsung's RAPID (Real-time Accelerated Processing of I/O Data) technology. By using free PC memory as a cache, RAPID was able to push the performance of the drive beyond the limits of the current SATA specification.

Samsung has now launched the 840 EVO mSATA. Designed for ultra-thin laptop PCs, this extension of the 840 EVO line-up features a compact mSATA form factor which is approximately a quarter the size of a 2.5-inch SSD. The 840 EVO mSATA is powered by the same MEX controller found in the 840 EVO. However, it utilizes Samsung's advanced 128 gigabit (Gb) NAND flash memory based on 10 nanometer class process technology. With each package having 16 layers of 128Gb chips, only four flash memory packages are needed to form a 1TB SSD. The 840 EVO mSATA also supports Device Sleep (DEVSLP) for lower power consumption as well as self-encrypting drive (SED) technology that is TCG Opal 2.0 and IEEE-1667 compliant.

The 840 EVO mSATA is available in a wide range of capacities from 120GB up to a massive 1TB. For this review, Samsung sent us the 1TB version of the drive which comes equipped with 1GB of on-board cache and is capable of delivering up to 540 MB/s sequential read and 520 MB/s sequential write speeds as well as up to 97,000 random read and 88,000 random write IOPS.
