Correct me if I'm wrong

i can't see any benefits to installing them on a secondary drive. if anything it'd cause more issues i'd think.

 

You talking about having the operating system on one drive and your applications on another drive? Yeah...I agree...that doesn't make much sense.

What might make more sense is to have your operation system and applications on one drive and your documents on another drive. That way if you ever need to reformat your drive you don't need to backup your documents to another drive before doing so.

When you say programs like Photoshop I don't know if you mean third party applications or something else.

But I've been told that for Apple apps (like Final Cut Express or iLife) Software Update won't work unless they're in the Applications folder. Something you might want to know...

 

I keep photoshop, dreamweaver, and all the other biggies on my external HD, for the simple reason that I don't have enough space for them on my main HD. They work well, never had any major problems with it.

 

i have it on my 80gb internal hard drive. the only benefit i can think of is that it will load faster, unless you use a firewire.

 

As MurphyM mentioned, the apple apps need to be in your apps folder, but programs like PS will run ok from an external drive, as for benefits, there aren't any, just a little slower start up, but still worth using in conjunction with a scratch disc if you got a spare HDD and want performance use the boot drive for most app storage, it's what the things for (if you got the space that is)
