Sorry for the long read, just want to be clear about the problem. I'm a retoucher & CGI artist. My home based studio is well equipped, but when I am working off site with my Ad Agency clients I am often stuck on workstation that is less than ideal. Typical problem working big 5-10 GB Photoshop files is running out of ram. When that happens, Photoshop needs a scratch disk. If that's not available, it will look to the boot drive. When the boot drive fills up with Photoshop doing it's scratch stuff, then that's when everything just locks up. Both my home workstation and all my agency clients are using MP 5.1 towers. As such I don't think I can utilize anything with a thunderbolt connection. Is there a portable, bus powered SSD that I can carry with me that plugs into the face of the MP 5.1, where the method of connection is allowing the full read/write speed of an SSD? Just looking for an easy carry on solution where I don't have to freak out the company IT guy by cracking open the case on the MP. Thanks!
