External hdd performance - Seeing 65-70mb/s write speed when writing thru Mac and with windows(tried on 2 hardware rigs) it goes max to 25MB/s. and I know both mac/win7 hardware in not USB 3.0 compatible. Possibly what could explain this ?

May be on Mac you are using USB 3.0 port and on Windows PC you are using USB 2.0 port so the slow speed

That isn't the case: That's why mentioned - /and I know both mac/win7 hardware in not USB 3.0 compatible./
