I would rather stick to just one drive.
Now I have MX100 256GB, and this capacity is ok for me.
However I am considering changing it to:
850 PRO 256GB or MX100 512GB - about the same price and larger version of crucial is much faster than 256GB MX100
I was thinking about creating my workspace on a pendrive, I have exactly this one on my mind http://www.storagereview.com/patriot_supersonic_magnum_usb_flash_drive_review%C2'>
My workspace would be a few application installed on a pendrive: Autodesk Maya, Photoshop, etc... Would this work? Would speeds allow for fluid workflow?
