  • FAQ

Hard drive technology dates back to 1956 when IBM used them in huge mainframe computers. The first model had 50 platters, each 24-inches in diameter, stacked and enclosed in a metal box the size of industrial refrigerator. It cost $10,000 and stored 5 MB of data.

Today, desktop units store 10 TBs in a 3.5-inch casing, and cost roughly five cents per gigabyte.

A mechanical hard disk drive (HDD) is a remarkable feat of engineering. Magnetically-coated circular platters rotate at high speeds around a central hub; a magnetic head at the tip of an actuator arm reads and writes data on the platters by extrapolating binary code from changes in electrical current. The head skims just nanometers above the platters with extraordinary precision by gravitational physics, while simple mechanical implements keep the platters free of dust and debris.

In personal computing, the IBM XT in 1983 was the first to encase hard disk storage inside a computer case. Three years later, Apple added a SCSI port in the back of the Mac Plus for connecting an external hard drive for expandable storage. The technology retains this same general essence today.

Advances in predictive mathematics and miniaturization have driven advances in hard disk storage capacity. Fast-spinning motors have leveled up read and write speeds for faster performance—a standard hard drive for gaming spins at 7200 RPM and has a capacity of 1 or 2 terabytes.

Hard disk drive manufacturer consolidation through the years has left only three OEM hard drive companies in the market: Seagate, Western Digital, and Toshiba.

Are hard drives almost obsolete?

With inexpensive cloud storage backup services widely available, and consumer-grade solid-state drives dropping in price, some think the illustrious span of relevance for hard disk storage is coming to a close. Nonetheless, HDD storage solutions continue to deliver on performance and price value propositions.

Budget-conscious performance PC users have a small SSD for the operating system and main applications, running it in tandem with inexpensive hard disks used for file storage. Hybrid drives build in the same features with a small solid-state drive encased with a standard HDD.

For home media and business, HDD remain the go-to for shared storage and backup file servers. Disks specialized for Network Attached Storage (NAS) and video surveillance systems offer optimized performance for those systems.
