I just bought a 1Tb internal hard drive from WD ?
it says 5400-7200 RpM
and all the other series they have like Blue or Black are all 7200 rpm
what does 5400-7200 mean?
and should i bother getting it changed to a 7200 rpm ? or will this be fine ? i require 7200 rpm…
thanks

Answer:it has intellipower on it. meaning that if your mobo/chipset supports it,it will slow the drive to reduce noise and heat and power consumption and then speed it up when it is needed. Thats why it has the "green" designation on it.
Edit: From WD's FAQ's about their Green drives :
How does WD Green Power drives compare to traditional 7,200 RPM drives?
Answer
Overall, this product meets the performance requirements of most applications while delivering significantly less power consumption. If your application requires mostly sequential read/writes, then the drive will perform comparable to a 7,200 RPM drive. However, if your application performs mostly random mode operations, then the performance may drop by about 10% because of the latency time. If the Green Power product does not meet your performance needs then we have our Raid Edition line of 7,200 RPM Enterprise drives that will deliver the performance you need at the industry’s best reliability.
