The evolution of the SSD has arrived as the Samsung 840 Evo 250GB 2.5" SATA-3 Internal Solid State Drive Kit with more speed, more reliability and much easier upgrade tools. Combining the best SSD technology from Samsung, 840 EVO delivers a superior computing experience. The 840 Series SSD was significantly improved upon in the 840 EVO. Samsung's new TurboWrite technology delivers dramatically faster sequential write performance. And, with upgrades to NAND, a new controller and firmware, the 840 EVO has superfast responsiveness under everyday workloads.
The Samsung SSD 840 EVO introduces two important features for data security: hardware-based AES 256bit Full Disk Encryption (FDE) and PSID. Hardware-based AES Encryption helps safeguard data against attack by encrypting all information on the disk at the hardware level, which means there is no detrimental effect on performance. When you forget your SSD security password, PSID protects your data on the drive by executing a cryptographic erase which returns the drive to its factory status, preventing any unauthorized access to your data.
