Drive speed too slow to run multicam?

Sorry, I tried deleting one of my posts but accidentally ended up deleting the whole thread I guess...

This is my question though:

I have 1920X1080 30p HD footage Linear PCM footage shot on Canon 5D Mark 3's> Converted to PRORES 422HQ (3 Angles) That I'm trying to multicam in FCP editing off a 2TB WD red eSATA drive... Are hte drives too slow?

Convert them to ProRes 422 and you might have a shot. HQ is going to increase file size and data rate considerably, but won't gain you any quality from an 8bit h264 file. It's overkill.

Try Bret's idea, and if still not working, maybe consider working with proxy footage at lower rez, then use the completed EDL and media manager to assemble the finished cut in full rez again. I know, it's a step back to the 80's and "offline" editing, but when you just have too (redacted) much footage, it's one coping strategy.

That should be OK for 3 threads.
Anyway, you don't need full quality for cutting, and some drop frames won't hurt you.

You are right Steve.
The fact is that 100MB/s (800Mbps) is the equivalent to some 5 threads of ProresHQ, but is not the same to be reading a single file than three different files (located in three different places of the HD) at the same time.
I mean that being able to read 100MB/s doesn't mean to be able to read 3 x 33MB/s.
