SimpleTech's website says that model is 5400rpm (see Specifications tab):
I also Googled that model number. Some stores were designating that model as 7200rpm. That's either a mistake or dishonest advertising. Either way, I think you are entitled to a refund or replacement from where you purchased it. That is, if you really want a 7200rpm model for the speed. You should get more battery life with a 5400rpm hard drive.
I wanted a faster drive for my Toshiba notebook. So I bought a SimpleTech 7200rpm Hard drive (STI-HD2.5/60H, 7200rpm 9.5mm). The "SimpleTech" label states that it's a 7200rpm drive, 9.5MM 60GB, etc...
However, SimpleTech places their Label over top of the original OEM Drive Manufacture's label. So I carefully peeled off the SimpleTech Label reveling the OEM Drive Manufacture's Label.
Low and behold - The OEM Label states that the drive is made by Samsung and is model number: MP0603H - a 5400 RPM Drive!!!!
What is going on?!? How can SimpleTech sell Samsung's 5400 RPM DRIVE as a 7200RPM Drive?? Did I just get ripped off?
Any help would be greatly welcomed!!
