From the Manufacturer
840 EVO is significantly faster than a standard HDD, providing more rapid sequential and random read and write times for every task. Samsung's new 3-bit MLC NAND flash memory stores data more efficiently, increasing both speed and reliability. Whether it's a heavy workload like video file editing or a simple task like a virus scan, 840 EVO runs every job smoothly and quickly. Multitasking is a simple job for this SSD, which can operate several tasks simultaneously nearly three times faster than an HDD.
