disk alocation
Hi, I have just built my first PC and am total new to this so sorry if this seems a little remedial. I built it to edit and grade on. For storage I have a SSD for the OS and the programs, 2 x HDD in RAID 0 of 6TB and another 4TB HDD. The media will naturally go onto the RAID but I’m unsure if I should put this as the scratch disk also, my preview, media cache and so on or if the system would benefit from being able to read/write these from there own disk.
Sequential R/W’s
RAID read 350 MB/s write 175 MB/s
HDD read 170 MB/s write 168 MB/s
When it comes to the write speed as you can see there is little in it. Anyone have any idea how this would play out? -

Media on your fastest read drive (the raid), media cache on any other drive but the footage drive. What you’re optimizing here is throughput.
Lets lay you just used the RAID. well if you rendered, you’d be reading to the same drive you’re writing which could create a bottleneck beyond the speed of processing.
Using two separate drives, one for media and the other for cache, and with today’s processors you’re really only dealing with the CPU as the bottleneck. The one exception is totally uncompressed video or TIFF/DPX sequences.

Thanks for getting back, I shall put Video and Audio Preview, onto the HDD, project files onto the c drive and Media onto the RAID. I was going to use the HDD for back up in case of drive failure in the RAID too. I was thinking the cache wouldn’t be too big and I shall clear it regularly, How do you think this sounds? If the RAID goes beyond 60% full I shall rethink it all a little but I cant see it going there in the near future.
I’m surprised you say the CPU is the bottle neck, people always seem to point to the transfer speed bottle necks.
