Most Hard Disks these days are in sealed containers. Most people judge how fast or how slow a hard disk is by how fast it will do certain things. The technical people can talk about wetstone tests, drystone tests, slighly damp rock tests, but, if you can save a 20 page word document in 10 seconds on you old machine and 2 seconds on a new machine then what is the RPM of both
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
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.

Hard disks rotate constantly at high speed from 5000 to 15,000 rpm.
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.
For internal hard drives, the highest I've seen being sold were up to 15000 RPM. Usually hard drives that come with computers pre-installed are at 7200 RPM so it's more than double that.
You cannot in any sensible way. RPM is a measure of (angular) velocity whereas litres is a measure of volume. Your hard disk will have an rpm but what does litres mean in terms of the disk?
Go to my computer then select the drive where your hard drive is (usually c:) it is usually labeled as something like local disk c: then you are able to view everything saved to your hard drive
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.
Enterprise class disks generally spin faster (over 15,000 RPM), have higher capacities, and are much more expensive.
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.
A computer hard disk or hard drive (fixed disk) is hardware.
