When playing an audio CD, a motor within the CD player spins the disc to a scanning velocity of 1.2–1.4 m/s (constant linear velocity, CLV)—equivalent to approximately 500 RPM at the inside of the disc, and approximately 200 RPM at the outside edge.

Which disk is fast?

HDDs can copy 30 to 150 MB per second (MB/s), while standard SSDs perform the same action at speeds of 500 MB/s. Newer NVME SSDs can even show speeds of up to an astounding 3,000 to 3,500 MB/s. With an SSD, you can copy a 20 GB movie in less than 10 seconds, while a hard disk would take at least two minutes.

The hi-res 24-bit/96kHz or 24-bit/192kHz files should, therefore, more closely replicate the sound quality the musicians and engineers were working with in the studio.
