I'm not doing any video so I don't have that kind of huge storage needs, but all the audio is going to need to be backed up. The amount of time it's taking me to rip hundreds of CDs is crazy. I can't go through that again. I have no choice but to have a backup drive.
Using a rough estimate, I might be able to fit everything that I have right now on a 100GB drive. 500GB and under is very inexpensive now. I just liked the concept of recoding to a solid state drive and not having to worry as much about losing everything due to some sort of mechanical failure that HDs are prone to. Maybe I can archive everything on 15 or 20 dual layer DVD disks too? Put them in a safe or safety deposit box etc.
Can you imagine dragging around 1,000 or more original CDs every time you did a gig? As it is there is a ton of other stuff to lug around like speakers, amps, mixers, cables, mics, and on and on. The times they are a changing...
