Flash performance and endurance is a tricky subject, but we're confident that Samsung's flagship, the SSD 840 Pro remains one of the best in both categories. We knew Samsung would really have to step things up next, it was only a matter of how, of course, and the company revealed that part at its annual global summit. Having aced its attempts at speed and durability, Samsung seems focused on solving flash's biggest sacrifices: size and affordability.
Its new SSD 840 Evo lineup has models spanning from 120GB to 1TB, with the largest costing only $0.65 per gigabyte thanks to its use of TLC NAND.
Meanwhile, the Evo drives promise solid performance courtesy of several ingenious features, including an SLC-based write cache ("TurboWrite") as well as a secondary caching system called RAPID (Real-time Accelerated Processing of I/O Data) that dips into system memory.
The Samsung 840 Evo is the new member to its highly-regarded SSD 840 range. The 840 EVO sports 19nm 128Gb TLC NAND, proprietary firmware and the latest-gen multi-core MEX controller. The 840 Evo features in 120GB and 250GB capacities speeds of 520MB/s, and in its top capacities of 500GB, 750GB and 1TB registers 520MB/s.
The Samsung 840 Pro SSD has been fitted with Samsung's latest MDX controller, a triple-core ARM-based chip that supports SATA 6Gb/s and can be paired with the latest 20nm NAND flash memory. Samsung claims a MTBF of 1.5 million hours and a 1500G shock resistance and the 840 Pro is backed by a limited five-year warranty.
