>>>>>I have a Windows 8.1 Pro tablet - but it has a rather small SSD card built into it. Luckly I have a 128gig SD micro card for it. So now I want to install Visual Studio 2015 on it. Problem is when I try to select my SD Micro Card drive (d:\) - it tells me that I can not install VS 2015 to removable media. I haven't tried to install nay other versions of Visual Studio yet. So is there a work-around for this? Is there some kind of hack I can do to let the install go to my micro sd card???

I don't know how V: drive would be treated in either case. SUBST is quick to test, NET USE would take a little longer to set up.

>Yep - I used the method in the link I provided above. The micro sd card I used is one of the super-fast ones you can get from samsung (used mostly for video recorders and high speed cameras) so that will not be an issue. Of course I'm doing all this on a wimpy samsung ativ tab 3, sooo not exactly a powerhouse machine..haha.

Good to know - thanks.

I think in some cases SD speed depends on the speed of the reader it's plugged into. IOW you might have a super fast card but the reader might not be able to take advantage of it - like plugging a USB3 device into a USB2 connector.

Maybe you could fire up Task Manager, and see while running VS if you're CPU-bound. If so then you know your storage is "good enough" :)
