Hey Matt,
I too have just recently started the move to Davinci, as Adobe is going out of their way to destroy the development of their professional tools. And, promote Adobe Express, which I have heard from clients does not do a very good job.
There is plenty of tutorials available for Davinci + you have tighter integration with hardware too. I purchased the Blackmagic mini panel as it comes with Davinci Studio included… – You can start for free with the free version.
I am also moving back in to Avid Media Composer just for the sake of it.
In effect, if you build your system right, you should be able to have all three of the above installed. And, use at your convenience.
HDD is a spinning thing, bulky, and will never spin as fast as you want it to. Particularly when the operating system are fighting with the NLE software, whilst writing ot virtual memory, and accessing other pieces of software. Not forgetting that anying mechanical has a higher possibility of breaking down -having said that, SSD also has it own set of problems.
My current system (Laptop PC) has got 1 x 1Tb SSD for operating system and software. Then I put in 2 x 4Tb Samsung 990 M2 Pro SSDs (Up to 7,450 transfer rate) with space for a 3rd drive.
Amen to not using proxies. Just recently had a project presented where the proxies had the wrong audio configuration, which PPro could not work with.
On the above setup I can comfortably work with 4 tracks of 4K in my PPro sequence.
My best advice: By all means use HDD for back-up. Just make sure to disconnect when not using them. As they will randomly stop and start – which will slow down your system. Or worse, your NLE software will decide that they have the files they need, and start scanning them. Maybe evn add them tour project.
Depending on who pays for your work, you should also consider that SSD external drives are reaching a cost for archieving comparable to video tapes of yesterday, if you can charge that back to the client?
My go to is the Samsung T7 or T9 drives.
Hope that this helps.
