The speed of a magnetic hard disk drive (HDD) is primarily determined by its rotational speed, measured in revolutions per minute (RPM). Common speeds include 5400 RPM for standard consumer drives and 7200 RPM for higher-performance models. Some enterprise-grade HDDs can go up to 10,000 or even 15,000 RPM. Additionally, the data transfer rate can vary, typically ranging from 80 to 160 MB/s, depending on the drive's specifications and technology.
What else can I help you with?
Is a magnetic disc affected by a theft detection device or magnetic theft alarm sensor?
Yes, a magnetic disc like a hard drive or floppy disk can be affected by a theft detection device or magnetic theft alarm sensor due to the strong magnetic fields they emit. This can potentially cause data loss or corruption on the magnetic disc. It is best to keep such devices away from magnetic fields.
What is hard disk explain briefly?
The hard disk is a device which attached in a CPU where data , program ,and folder are being stored .
Why hard disc are magnetize with iron oxide?
Hard-disks are coated with iron oxide because it reacts to a magnetic source ! The information on a hard-disk is read and written by a magnetic 'head' which scans across the surface as the disk rotates.
What are the type of ROM?
two types - magnetic in the form of magnetic tape,magnetic disc and optical in the form of compact disc.
What is the correct spelling for computer disc drive?
"Disc" refers to optical media, such as CDs or DVDs. "Disk" refers to magnetic media, such as hard drives. So the answer depends on which drive you are referring to; most have both an "optical disc drive", and a "hard disk drive".
What is magnetic platter?
A magnetic platter is something that is found in your computerÃ?s hard drive. It is the actual place where the data is stored, is shaped like a flat disc, and made of metal.
Why Arrange compact disc,hard disk,digital versatile disc,pen drive,floppy disk in descending order of access speed and storage capacity.?

Is CD-r disk a hard disk?
No, it is an optical disc. A hard disk is defined as a device that stores data on spinning magnetic platters. Although a CD is 'hard' (rigid) as opposed to the flexible inside of a floppy disk, that does not classify it as a hard disk.
What medium is magnetic disc?
Magnetic discs are a storage medium that uses magnetic materials to store data. Common examples include hard disk drives (HDDs) and floppy disks. Magnetic discs are commonly used in computers and other electronic devices for data storage and retrieval.
Why are there no poles on disc magnets?
Disc magnets do not have poles because they have a symmetrical magnetic field that runs from one flat face to the other. This design allows for a more uniform magnetic field across the entire surface of the disc magnet, making it useful for certain applications such as magnetic levitation or sensor devices.
How do you reformat a Mac Pro laptop With out lossing anything?
Reformatting a hard disc will wipe the contents from the hard disc. You will need to backup the contents of the hard disc onto an external disc before reformatting and then copy the contents back to return it to the newly reformatted disc.
What is the speed of rotation of the magnetic field called?
The speed of rotation of the magnetic field is called magnetic flux. It is a measure of the flow of a magnetic field through a particular area.
