Samsung 850 Evo 500GB SSD

Upgrade virtually every aspect of your computer’s performance with Samsung’s new 850 EVO, designed with state-of-the-art SSD advancements including 3D V-NAND technology (sequential read and write speeds of 540MB/s and 520MB/s, respectively). Faster your PC experience twice. It can be used with any Laptop or Desktop PC. I bought it from USA with 5 years warranty. I want to sell it because I already have two of them.
