The most common range is 5400-7200 rpm. There are also 10000 and 15000 rpm drives. Solid state drives do not operate on the same principals as disk drives, and do not spin at all.
Hard disks rotate constantly at high speed from 5000 to 15,000 rpm.
IDE hard disk, SCSI hard disk, SATA hard disk, External hard disk, it is also differ by RPM speed for the HADD. I hope that helpes.

depends on the hard disk and the size of the file--if your looking for a new hard disk, check what the rpm's are the more rpm's the faster your hard disk is
1. Disk rotational speed in rpm. "HDD data transfer rate depends upon the rotational speed of the platters and the data recording density."
The speed varies from the size of the floopy disk. on average it tends to be quite slow. (:
A modern hard disk will spin much faster than a floppy disk. A floppy disk will spin at around 300 RPM. A hard disk will vary depending on model and configuration. A mid range desktop hard disk will spin at around 7200RPM. Laptop hard disks usually run at slower speeds of 5400RMP. High end desktop and server hard disks can spin at speeds in excess of 10000RPM.
If you've ever tried to open or save a document to/from a floppy disk, you'll know that floppy disks were slow. Imagine if that was your hard disk. Your hard disk contains your applications, user data, operating system - everything that is meant to be retained when the PC is switched off. The faster the hard disk, the faster data can be loaded and saved. Therefore, if you get a HD with a larger cache or RPM speed (10,000 over 7,200), game data will load off disk faster, applications will be able to read system data faster, and your PC will go somewhat more speedily. A faster hard disk isn't a replacement for a spacious amount of RAM, however.
it depends on more then rotational speed. The Rotational speed and latency time is related as follows: Latency time = (1/((Rotational Speed in RPM)/60)) * 0.5 * 1000 milli seconds
7200 rpm is quite common.
LaCie offers more than one external hard drive with 1TB of disk space. According to the product specifications on the LaCie website, most of the 1TB external hard drives have a rotational speed of 5400 per minute.
