So instead of spending money to make it 5600 RPM, they dumped money into research for something even faster, and go 7200 RPM, a new limit.....and then on up to 15000. Just my guess though.
10800 yes..... 5400 x 2 = 10800
7200 x 2 = 14400. Pop on a little bit, and it's 15'000
You will often see hard drives advertised as being capable of a certain RPM (Revolutions Per Minute), this figure (as the name suggests) refers to how many times the spindle makes a complete 360Âº turn in any single minute.
The higher the RPM, the faster the data can be read from the platters, which increases overall performance.
RPM values range from about 5,400RPM to 12,000RPM and above
Quite simple really.
Businesses need FAST data transfer....servers and such. So they make HIGH rpm drives. Sure enough....PC enthuisasts, and gamers want these too...so now they're common things
