Hi there,

I'm going to see if I can use a 10TB drive that's almost full of 4K material in my 2010 Mac Pro (I have four free 3.5"-drive slots).

If a drive this large works, then I'll need another big SATA drive, or two, because my only hope of editing a new 4K project (I was looking into buying a Mac Mini because at least it has Thunderbolt and USB3, but it started gettiing expensive when I realized I had to add an eGPU and an external 4-drive hd bay, etc.) is to use the fast internal bus (is that the right term?) and internal hard drives, in my old Mac Pro.

So my question is: if I transcode 10TB of 4k footage, to, let's say, 1/4 resolution DNxHD files, will these files take up more than 10TB of hard drive space? Or less? Is there an Avid calculator I can use? I just want to get the right size hard drive(s).

Thanks for any advice,

Malcolm

I notice that back in 2015, in response to what seems to be a similar question, smrpix said:

"Doubling the space for your source footage is probably a good starting point, but it could vary dramatically in either direction"

Perhaps it depends, though, on whether a person transcodes to 1/4 resolution, or 1/8, so I will wait for more certainty before I order hard drives on amazon.

regards, Malcolm
