I suspect that an external drive speed of 7200 will not be fully utilized unless there is a USB3 or eSATA connection. For modest projects 5400 should work.
My thoughts exactly. A USB2 connection (or a USB2 External Drive) won't take advantage of the speed a 7200 drive brings. Unless you have a USB3 connection, or an eSATA connection you would be better off using the internal drive for projects then archiving to an external to keep your space maximized.
The other thing to consider (especially on a laptop) is the USB Bus. There might be 2, 3 or 4 ports - but there might only be one bus. That would mean an external USB Audio Interface and a USB Hard Drive would be sharing the pipeline creating a bigger bottleneck. Not to mention - a USB2 bus can be seriously crippled when a USB1.1 device is plugged into it as the bus will drop it's specs and operate at the slower speed for EVERYTHING that is connected. USB3 does not have this limitation - it can handle multiple speeds at one time.
Just some things to consider.
EDIT: I just noticed this is a month old post that got brought back to life. My comment is likely irrelevant by now :)
Hi codamedia ,
your comments are very relevant

i started this topic before I upgraded .
here's what i do know for sure about my set up . i have one USB3 slot and one USB 2 slot on my lap top.
i had read someplace that USB 2 audio interfaces do not play well w USB 3 , so I put the Yamaha on the USB 2 slot and then put my mouse into the USB 3 slot .....
Now my sound card works (as well as a 16 bit audio card could be expected to work as ) and I have a working mouse .
we all know that i will probably have to add the peripherals that i will need in the future ( more USB 3 , and the external HD 's ....)
As it stands now I'm up and running , able to record audio and learn my way around X3 ....for now I'm very happy....
thank you for your comments
Kenny
