Question: is this hard drive a 7200 RPM or 5400 RPM?
Document: Although beta macs was very helpful and courteous over the phone, they fail to state anywhere on here that macbook pros prefer 7200 and not 5400. so likely the harddrive they send you will not be recognized by your mac. not everyone is a computer guru and knows this. so all in all its just a waste of time and youll have to return it and wait for another hard drive. truthfully though they seem like a great company and i am willing to just pay the difference for the hard drive i need.
You'll find that the manufacturer of the hard drive (HD) you receives varies, and is a 5400 rpm. I only give it a 4 star because of the problems in installing the HD and operating system:1. Hardware installation is relatively easy with the correct tools, but be aware that this HD is thinner than the OEM HD that came with the macbook.
This item did not work and I want to return it. I need to get an hard drive that works.
Bought this hard drive, installed it quickly and now my mac works better than it used to. Glad i bought it
lost the hard drive on my mac and put this in with an upgraded os for less than 100 dollars, thx amazon
Purchased this hard drive 2 yrs ago and have had no problems. Was a snap to put in and increased my memory 5x.
thank you for the hard drive. It was exactly what was ordered. I am very pleased. I only wish if came formatted for a MAC already.
We added this hard drive and 4GB memory about nine months ago and so far, so good. Our MacBook Pro is happy.
That I was able to replace my hard drive - ALL BY MYSELF!My computer now works like it's brand new!
It works great, it arrived quickly. What else is there to say?I I am completely satisfied with this hard drive for our Mac.
Answer: 5400 RPM
