About the 'intelligent drive management' I am not that sure. It may be better than drives, which do not power down at all, but it still annoying that you cannot switch off the drive completely. For example the Seagate drives behave the same way, but in addition you can switch them off, so they will stay off when you switch off and on your PC. The WD will power on every time you power on your PC, which I personnally do not like at all.
