Storage recommendations needed- video editing
I'm looking at a Mac Pro and need some good options for storage. I'm not going to spend the money on upgrading the internal PCI-e to 1TB, so I'm getting the base 256gb configuration for the OS, Apps, and Parallels / Virtual machines.
Currently I have a 128gb SSD for the OS etc, and have my Users folder mapped to a internal 7200RPM 1TB drive. It works beautifully, but since Apple took out the option to add hard drives...... I don't know what to do.
As the subject says- this will be for video editing. I need at least 500gb of additional storage, but 1TB would be more comfortable. I'd also like to possibly map some user folders to the external- likely Desktop, Documents, Dropbox, Pictures, Music, and Movies.
So on to my questions.
#1. Would a USB 3.0 external SSD or even 7200RPM drive be fast enough to work with video editing? I assume it would be about as fast as an internal HDD/SSD right? Or no?
#2. Mapping... is the way I'd like to do it a good/bad idea? What's the best option for wanting to retain saving to particular locations, but having them actually stored on a larger drive? Or... would it be better to just form new habits on where I save things?
Thank you for any and all feedback!
PS- Can I use Crucial RAM or do I need the much higher priced Apple provided in a BTO config?
