Internal Hard Drives

Perform a cost-effective upgrade to your home or office computer with these advanced internal hard drives. Each one adds storage and speed so that your system can perform effectively. Select the best hard drive for your current configuration from brands such as IBM, Seagate, and HP.

High Capacity
Add extra storage space to your computer with these internal hard drives that come in a variety of sizes. If you're working with large video and photo files, choose a hard drive with a 2 TB or 3 TB capacity. For a personal computer, select a cost-efficient model that has 1 TB or less of storage space.

Fast Data Transfer
Each of these hard drives is designed with sophisticated data transfer technology that saves and retrieves files quickly. For high-speed data transfer in demanding computer applications, choose a hard drive that is capable of up to 6 Gb/s. In general-use computing, a hard drive with a speed of 3 Gb/s provides excellent performance. Make the most of the drives by installing them in an updated computer.

Multiple Interface Options
These internal hard drives are designed with a variety of interfaces, so you can select the one that is compatible with your existing system. For high-performance storage of crucial files, choose an advanced SAS drive. Don't worry about shutting down your system — SAS drives are hot swappable. If you're looking for a cost-effective solution for a data backup, look to SATA drives.

Secure Installation
These hard drives are designed for internal installation, drastically reducing the chance of accidental disconnection. Each model uses standard connection ports, so you can integrate it into your system quickly. Most items come with basic installation instructions for maximum convenience.
