How does rpm in a HDD effect the PC (1 Viewer)

[SashatheMan]

i heard theres those new Hard drives that have rpm of 10,000 and just wondering what does it actually make the PC better for?

that would be fucking loud.

10,000 RPM drives have been around for a while, but mostly for enterprise SCSI drives because of cost.

A hard disk is one of the slowest components of memory in the computer. RAM is in the order of nanoseconds for access, but a hard disk is in the milliseconds. A big difference.

The disk is slow because on average it would take 1/2 a rotation of the platters for the head to be over the area of the disk with the wanted data. Thus, the faster the disks spin, the lower this time would be.

maybe , maybe they did it so it wont be loud.

so what that for example increase the speed of copyin files? or what?

yes

on average, every file access (read/write) would be faster, because the seek time to the data blocks has been reduced.

It would speed up anything involving the hard disk.

Note that things you don't even realise need the hard disk. Most modern applications would need to use the hard disk at some point, even if you are not trying to save/load a file ...

how do u find out what the rpm of my hard disk as the moment are?

Most likely 7,200 if your computer was made in recent years. You can find out what hard disk you have, and if its not written on the hard disk, go to the manufacturer's website and look it up.
