From protecting treasured family photos and personal music collections to developing next-generation consumer electronics devices and large enterprise networks, Seagate delivers advanced digital storage solutions to meet the needs of today’s consumers and tomorrow’s applications.
When the first hard drives began shipping in 1956, only big corporations could afford the cost and space required for these one-ton behemoths. Today, digital storage is all around us. Whether you realize it or not, you are probably interacting with digital storage devices on a daily basis. Every time you visit an ATM machine, record and replay a favorite TV show on your DVR or download a song to your portable media player, you are accessing or storing information on a hard drive. Every day, content passes through numerous types of storage devices before it makes it to your office computer or personal media player.

In our culture of downloading and instant access, you can find a seemingly endless amount of content to download, enjoy and share—whenever, wherever you want.
The digital storage market continues to grow at a rapid pace—fueled by the explosion in content being created and consumed, as well as new legislation requiring businesses to store specific records and information.
