Internal Hard Drives

Need more storage for your games, images, music and movies? An internal hard drive upgrade or a second drive may be what you are looking for. Internal hard drives are used as main storage in desktop PCs, workstations, and servers. Nowadays, small form factor internal hard drives are used in consumer electronic products like mp3 players and digital cameras as well. Regardless of your application, Newegg.com presents an extensive selection of internal hard drive products for you to choose from, from hard drive manufacturers like Western Digital, Seagate, HItachi, LaCie, Maxtor and others.

Understanding Internal Hard Drive Specifications

When selecting a hard drive, there are two main things to consider: speed and capacity. Budget permitting, always go for the fastest drive you can. Speed is measured using the RPM figure a faster rotational speed means greater performance, especially in games, but may cause greater heat and noise. The capacity, measured in GB (gigabytes), should depend on your own storage requirements. A higher capacity drive will invariably cost more than a lower capacity drive, so a balance must usually be struck between capacity and cost. In addition, the hard drive interface IDE, SATA, or SCSI determine a drives application: IDE and SATA for personal storage and SCSI for enterprise, mission critical storage.
