Hard drives the size of today's 5.25-inch (1.6-inch high) CD drives are produced. 1987 - 3.5 inch hard drives up to 500 MB are produced. 1997 - IBM introduces a 16.8 GB hard drive for desktop computers.
Hard drive or HDD, HDD are magnetic recording media used for data storage. Hard drives, which were only used in computer centers due to their large size and high price, entered our daily lives with their sizes small enough to fit in cell phones and digital cameras.
Hard drives are mainly used in computers. Large amounts of information such as audio, video, software, databases are stored on hard drives for use when needed. Today, although hard drives are extremely fast in transferring data, they are slower than RAM because they are electromechanical. They are used as auxiliary and permanent memory in computers. When computer software starts to run, the information needed to run the software is read from the hard drive and transferred to RAM, which is much faster. If the necessary part is too large to fit in RAM, the computer uses part of the hard disk as RAM memory.
Computer hard drives are usually fixed inside computers, there are also portable drives that can be connected to computers from the outside.
Data storage units used in their place before hard drives were called "magnetic tapes" and "magnetic drums". First commercial example made in 1950 ERA 110 magnetic drum, 1 megabit (1 bit = 1/8 byte)
2011 - Seagate manufactures and releases 3000 GB (3 TB (terabyte)) (3.5") hard drive.
2015 - Western Digital manufactures a 10,000 GB (10 TB (terabyte)) hard drive (7200 rpm).
