The first HDD [11] had an average seek time of about 600 ms. [12] and by the middle 1970s, HDDs were available with seek times of about 25 ms. [13]Some early PC drives used a stepper motor to move the heads, and as a result had seek times as slow as 80–120 ms, but this was quickly improved by voice coil type actuation in the 1980s, reducing seek times to around 20 ms.

In 1993, Seagate released the first Barracuda drive, with the ST11950. The drive had a capacity of 2.03 GB (1.69 GB formatted), was available with FAST SCSI-2 (N/ND models) or WIDE SCSI-2 (W/WD models) interface, and was the first hard drive ever to have a spindle speed of 7200-RPM.

A drive that implements S.M.A.R.T. may optionally implement a number of self-test or maintenance routines, and the results of the tests are kept in the self-test log. The self-test routines may be used to detect any unreadable sectors on the disk, so that they may be restored from back-up sources (for example, from other disks in a RAID ).
The power measurement is often the average power used while running the benchmark, but other measures of power usage may be employed (e.g. peak power, idle power). For example, the early UNIVAC I computer performed approximately 0.015 operations per watt-second (performing 1,905 operations per second (OPS), while consuming 125 kW).
HDD random access times range from 2.9 ms (high-end) to 12 ms (laptop HDDs). [33] Power consumption High-performance SSDs use about half to a third of the power required by HDDs. [34] HDDs use between 2 and 5 watts for 2.5-inch drives, while high-performance 3.5-inch drives can require up to 20 watts. [35] Acoustic noise
Two 2.5" external USB hard drives Seagate Hard Drive with a controller board to convert SATA to USB, FireWire, and eSATA Current external hard disk drives typically connect via USB-C; earlier models use USB-B (sometimes with using of a pair of ports for better bandwidth) or (rarely) eSATA connection. Variants using USB 2.0 interface generally ...
