AV drive

(Audio Video drive) In the late 1990s, an AV drive was a hard drive optimized for audio and video applications, which required long, sustained transfers of music and video tracks. AV drives were designed to postpone thermal recalibration so that writing to the disk would not be interrupted while periodic recalibration took place. Today, hard drives use servo calibration to monitor head alignment and have large memory buffers, which together adequately support real-time audio and video transfer.

SuperSpeed USB (USB 3.0)
Because of the much higher transfer rate of SuperSpeed USB, drives that use the USB 3.0 interface are sometimes touted as AV drives (see USB 3.0). See underrun and thermal recalibration.
