Q: 3. can i edit 4k raw dng straight of the drive?

A: RAW files are very large and intensive to deal with when editing. While this is a great product, it is only rated at USB 3.0, not USB 3.1, for speed. A G-Raid with Thunderbolt 3/USB 3.1 speeds would be a better choice, B&H # GT0G05753, while an option like the Glyph Technologies Atom RAID which uses Solid State Drives would be an even better choice, B&H # GLAR2000GR.https://bhpho.to/2rm2m3dhttps://bhpho.to/2rlzO9U
