I also use multiple drives. My desktop has 3 internals and 1 ext eSata.
But the laptop is limited.For now anyway-I do plan (already bought the carriage) on putting a SSD where the piece of garbage CD|DVD drive is. I have plenty of exteranl DVD players and writers-one is USB 3.0 also. It has a 750GB HD partitioned in 1/2-os and data. The external HD is USB 3.0 so it's pretty quick and I see no issues if I use samples on the laptop.
I was in a hurry with the laptop and negelected 2 things. The ram max and ESata-although not too many laptops I have seen have ext eSata. But USB 3.0 is very fast, not as fast. Max ram is 8GB. I know that's OK for now. I got a good deal on the laptop new. new I7 3rd gen-Nvidea 2GB video card\HD 1080 display, HDMI out, and I can switch to the HD Intel which also works with Sonarx2.
So it's got the power (after I deleted all the bloat crap) Even connected to my wireless network at home it runs sampled projects very well. I will disable it out of course.
Bet you didn't expect all this babble
Thanks as always John
