RAID 6 vs RAID 10 for video server

Hey everyone,

I'm currently working on configuring a new video server, and I'm torn between using RAID 6 or RAID 10.

My biggest concern is write speed, as RAID 6 offers no additional write speed, but using 50% off storage on mirroring, plus the extra price of scaling with RAID 10 is somewhat contradictory to the needs of this server.

I know that read speed is really important in video servers, but can you run one with standard write speed?
