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.
SPECsfs2008 is the latest version of the Standard Performance Evaluation Corporation benchmark suite measuring file server throughput and response time, providing a standardized method for comparing performance across different vendor platforms.

2009 - Western Digital is the first to offer a 1 TB hard drive in a 2.5 inch form factor. [57] 2009 – Western Digital ships first HDD with dual stage piezoelectric actuator [58] 2010 – First hard drive manufactured by using the Advanced Format of 4,096‑byte sectors instead of 512‑byte sectors. [59]: Overview
The period of time taken by the drive to perform this process is referred to as its spin-up time, the average of which is reported by hard disks as a S.M.A.R.T ...
A hard disk drive (HDD), hard disk, hard drive, or fixed disk [a] is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.
The information is sent from the computer processor to the BIOS into a chip controlling the data transfer. This is then sent out to the hard drive via a multi-wire connector. Once the data is received onto the circuit board of the drive, they are translated and compressed into a format that the individual drive can use to store onto the disk ...
Your best bet is to put in your request anywhere between 9 a.m. and 11 a.m.; after that, the average response time declines over the course of the day. Zendesk. As the graph shows, requests put in ...
The 2305-1 has a capacity of 5.4 MB and runs at 3.0 MB/second when attached using the 2-byte channel interface. Average access time is 2.5 ms. The larger 2305-2 has a capacity of 11.2 MB and runs at 1.5 MB/second with an average access time of 5 ms. [38]
