This smaller form factor is similar to that used in an HDD by Rodime in 1983, which was the same size as the "half height" 3½" FDD, i.e., 1.63 inches high. Today, the 1-inch high ("1/3 height," "slimline," or "low-profile") version of this form factor is the most popular form used in most desktops.
Some SATA II and later hard disk drives support staggered spin-up, allowing the computer to spin up the drives in sequence to reduce load on the power supply when booting. [44] Most hard disk drives today support some form of power management which uses a number of specific power modes that save energy by reducing performance.
As a family of form factors, it defines specifications for the mechanical dimensions and electrical interfaces devices should have, to ensure compatibility between disparate hardware manufacturers. The standard is meant to replace the U.2 form factors for drives used in data centers. [1] EDSFF provides a pure NVMe over PCIe interface. One ...

Although referred to by these nominal sizes, the actual sizes for those three drives respectively are 9.5", 5.75" and 4" wide. Because there were no smaller floppy disk drives, smaller HDD form factors such as 2½-inch drives (actually 2.75" wide) developed from product offerings or industry standards.
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. [ 1 ] [ 2 ] A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard.
Key benefits to using external disk enclosures include: Adding additional storage space and media types to small form factor and laptop computers, as well as sealed embedded systems such as digital video recorders [1] and video game consoles. [2] Adding RAID capabilities to computers that lack RAID controllers [3] or adequate space for ...
(The spelling disk and disc are used interchangeably except where trademarks preclude one usage, e.g., the Compact Disc logo. The choice of a particular form is frequently historical, as in IBM's usage of the disk form beginning in 1956 with the "IBM 350 disk storage unit".)
