I do a lot of video editing. Perhaps it's my laziness that I not only capture raw files to a USB external drive, but I also edit and render to USB drives. I'll make an assumption that it probably slows my work down somewhat, but more importantly, I'm wondering if working off the USB drive 1) somehow hinders video quality, and 2) shortens the life of a USB drive.
The laziness for editing on the drive is because it's a pain in the neck to move working files back and forth... I'm sure a lot of you can understand that point.
However, maybe I'm not doing my end-product any favors, let alone the external drives by over-working them. Any technical insights?
