Product Description

Samsung 250GB 840 Series SSD

The Single Best Upgrade for Your PC

With its simple 3-Step migration solution and industry-leading IOPS performance, the Samsung SSD 840 Series is the single best upgrade you can make for your PC. Samsung's new SmartMigration software takes the guesswork and headache out of moving your operating system and precious data to your new SSD. Once you're up and running, the 840 Series' amazing IOPS speeds empower you to multitask like never before.

Upgrading to an SSD is the easiest and most economical way to breathe new life into an aging PC. Today, most PC performance woes are the result of slow read and write speeds on behalf of the main storage device, not a lack of CPU performance. Upgrading to a Samsung SSD 840 Series can breathe new life into your old PC by enhancing boot-up speed, application loading, and multi-tasking performance.
