Choosing a Hard Drive? Compare and see some of the key features you need to consider.

Are you looking for better performance, speed, or capacity for your systems? Our hard drives offered by the leading brands of Seagate and Western Digital will meet your requirements, whether that's Surveillance, NAS or Gaming. Hard disc drives (HDDs) are storage devices for large amounts of data in your computer. They're mechanical, so they're slower than SSDs, but they offer the advantage of being able to store far more data, for example, you can now get 12TB on a single drive. Internal drives are available in 3.5in for desktop PCs. Consumer drives are usually connected to the system using a SATA cable, whilst drives for servers are sometimes connected via a SAS cable.
