Samsung has unveiled a new addition to its solid-state drive lineup, the new Samsung SSD 840 Evo. Available in capacities ranging from 120GB to 1TB, the new Samsung 840 Evo also features an upgraded Samsung MEX controller as well as the new 19nm Toggle 2.0 TLC NAND flash chips that should provide faster transfer speeds and have brought higher capacity models thanks to greater data density.

While it is still behind the Samsung 840 Pro series in terms of performance and reliability, the new Samsung 840 Evo will replace Samsung's 840 series and be available in 120, 250, 500, 750 and 1000GB capacities. It features a new Samsung MEX controller and uses new 19nm Toggle 2.0 TLC NAND flash memory and represents a logical move forward from the old Samsung SSD 840 that used 21nm Toggle 2.0 TCL NAND and the Samsung MDX controller.

As always, the performance depends on the actual capacity, so the 120GB will be the slowest with 540MB/s and 410MB/s sequential read and write performance and 94K and 35K IOPS 4KB random read and write performance. The 500, 750 and 1000GB models share the same peak 540MB/s and 520MB/s sequential read and write performance as well as 98K and 90K IOPS 4KB random read and write performance. The lone 250GB version has the same sequential read and write performance as the three larger SKUs but suffers from lower 4KB random read and write set at 97K and 66K IOPS.

Samsung also included a new Turbo Write feature that provides much greater performance for lower capacity models. The Turbo Write is practically a write-buffering technology. Samsung's new SSD 840 Evo series also comes with Samsung Data Migration Tool 2.0 that will help with data backup and provide easy upgrade and will ship in standard 2.5-inch form factor.

According to known details, the Samsung SSD 840 Evo should hit retail/e-tail as of next month while the price should be in line with the existing and quite popular Samsung 840 series, or somewhere in the range of US $110 for the cheapest 120GB model.
