The Truth About Hard Drive RPM (Rotations Per Minute)

I recently read this: How higher RPM hard drives rip you off | George Ou | ZDNet.com

This is what I found after doing a quick google search on Hard Drive RPM when I was customizing a Dell laptop that I was interested in buying....

My question is, is what that guy's saying is true? Or even to a degree? Like would I have any less storage space with a higher RPM than a lower one?

Is there ANY disadvantages to having a higher RPM other than slightly having to pay more?

Thanks.

What he says is true to a point but your money is not wasted. It really comes down to what you do, what performance you want, and how much drive space you actually want for a buffer.

It is commonly known that higher RPM Drives will always run faster than lower RPM drives. If you plan on using a laptop then the usual is a 5400 or 4200 RPM disc, with 7200 being the higher end option.

If a desktop then the 7200 RPM is nearly standard with 10K up to 25K in the highest end pcs, workstations, or servers that are demanding on access times.

You should be fine with a standard drive.
