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.
disk rotational speed in RPM
disk rotational speed in RPM
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.
1. Disk rotational speed in rpm. "HDD data transfer rate depends upon the rotational speed of the platters and the data recording density."
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.
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.
5400, 7200, 10000 or 15000 RPM (revolutions per minute)
A hard disk drive consists of one or more thin disks that spin at high speed (1200 to 15000 rpm) while magnetic heads read data from them, hovering extremely close to them without making contact.
Hard disks rotate constantly at high speed from 5000 to 15,000 rpm.
The speed varies from the size of the floopy disk. on average it tends to be quite slow. (:
it refers to how fast the actual physical disk platens are spinning inside the drive. seek time.
