In the mid-to-late 1980s the similarly sized Fujitsu Eagle, which used (coincidentally) 10.5-inch platters, was a popular product. They are available in 2.5-inch and 3.5-inch sizes; 2.5-inch variants are typically called portable external drives, while 3.5-inch variants are referred to as desktop external drives. "Portable" drives are packaged in Many Macintosh computers made between 1986 and 1998 featured a SCSI port on the back, making external expansion simple. The IBM PC/XT in 1983 included an internal 10MB HDD, and soon thereafter internal HDDs proliferated on personal computers.

Today's platters are 3.5" for desktops and 2.5" for laptops.

Because files are often scattered throughout the platter, the head needs to move to different locations to access all information. Retrieved October 19, 2012. ^ "Validating the Reliability of Intel Solid-State Drives" (PDF). Please provide a Corporate E-mail Address. For some time in the 2000s and early 2010s some desktop users would also use 10k RPM drives such as Western Digital Raptor but such drives have become much rarer as

The HDD's electronics control the movement of the actuator and the rotation of the disk, and perform reads and writes on demand from the disk controller. Some desktop and laptop computer systems allow the user to make a tradeoff between seek performance and drive noise. 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. Retrieved July 16, 2011. ^ "Hard Drive Help".

Recovery from logical damage can require file carving. This greatly reduced the cost of the head actuator mechanism, but precluded removing just the disks from the drive as was done with the disk packs of the day. Because of smaller platter(s), mobile HDDs generally have lower capacity than their greater desktop counterparts. Small Computer System Interface (SCSI), originally named SASI for Shugart Associates System Interface, was standard on servers, workstations, Commodore Amiga, Atari ST and Apple Macintosh computers through the mid-1990s, by which
