RAID 0 for Read/Write question
on Aug 31, 2013 at 2:29:51 pm

I'd like to set up (2) 1TB drives in RAID 0 to use in Premiere. If I do will they act as 1 drive...and will I not be able to Read media from one and Write to the other?

you can read and write to the same drive ! If you setup a RAID0, the 2 drives appear as one single drive to the system. You do this for increased speed. Drives read and write at the same time all day long. Even in the biggest shared storage systems, the shared volume both read's and writes.

I don't understand the question.

This describes striping (raid0). Each read or write request by an application causes a read or write command to each drive in the striped set. In effect each file is chopped up into pieces and the pieces are placed "round robin" on each disk in the raid set. This is both how performance is improved (if the chunk size is set correctly), and why data is lost if one drive in the raid set fails for any reason.
