The Single Best Upgrade for your PC

Upgrading your PC with a Samsung 840 is the most economical way to breathe new life into an aging PC. The 840 reads, writes, and multi-tasks at incredible speeds, enhancing boot-up, application loading, and multi-tasking performance. It's more than an upgrade--it's a complete transformation of your PC. This SSD has a capacity of 250 GB and comes with a full installation kit for easy setup and data transfer.

Smoother Performance and Faster Boot-Up

The 840 reads, writes, and multi-tasks at incredible speeds, giving you performance you never thought possible from your PC. Its blazing-fast performance is optimized to improve everyday PC productivity, including web browsing, email, multimedia, and gaming. In addition, the 840 Series SSD enables your PC to boot up in as little as 10 seconds.

Carefully Engineered and Fully Encrypted to Protect Data

Engineered for reliability, the 840 Series SSD gives you the latest in Samsung memory technology with the highest-quality manufacturing standards. The 840 is made from 100% Samsung components, the world's #1 memory manufacturer.

And the 840 has no moving parts, which means no hard drive spin-ups, no noise, and superior data protection. To further protect your data, this SSD offers AES 256-bit full disk encryption for worry-free data security.

Sleek, Lightweight, and Energy Efficient

At only 7 millimeters thick and weighing just 2 ounces, the 840 Series SSD has a thin, lightweight design that can make your laptop lighter to carry.

And because it contains no moving parts, the ultra-energy-efficient design consumes significantly less battery power, and allows you to enjoy up to 50 minutes longer laptop battery life than a standard hard disk drive (HDD) or competitor SSD.* This product also supports Device Sleep mode for Microsoft Windows 8 to help reduce power consumption.

Simple, All-in-One Installation Kit

Included with the 840 Series SSD is an installation kit that contains SATA data and power cables, screws, a 2.5-to-3.5-inch adapter bracket, and a SATA-to-USB adapter cable. The kit also contains a mounting spacer so its slim 7-millimeter profile will work with slim Ultrabook designs as well as with laptops with traditional full-height 9.5-millimeter drive bays.

Samsung's Smart Data Migration software is also included to make it safe and easy to migrate your data and operating system from your existing drive to the 840 Series SSD.
