What's a (7200RPM) Hard Drive?

7200 rpm has a faster hope time than a 5400 rpm because the data is coming around so much faster that it can be found and read faster. Also the 7200's usually enjoy extra memory to cache reads ahead of time and conceivably even get you your background faster than a normal read would pocket.

They even have 10000 rpm immediately
ye it means the disc spins faster for this reason its able to write and read information quicker ^_^
RPM is close to a car's engine, and it means "Rounds Per Minute." So the faster it is, (7200) the faster the read and write time.
yup
haha, yes
RPM or Revolutions Per Minute is how swiftly the platters inside the disk spin. The faster the hard drive spins, the better the background throughput, I.E, you get more background transferred per second.



The seek times enjoy nothing to do next to RPM, Seek times are dependant on the width of the platters (2.5" or 3.5"), and how speedy the head can move between tracks on the platter.



Think of respectively platter as an old Vinyl disc, and the pave the way as the needle! Each track is smaller amount than a micrometer, so the head have to be VERY accurate, and it takes time to catch to the correct track, which is usually mesauserd in micro-seconds.
