How much SSDs to use on computer for DaVinci Resolve Studio? I want to build a computer for DaVinci Resolve Studio. I want to choose how much SSD to use in it.
I thought of two variants. In both variants I will not store archive files on computer on which I will work in DaVinci Resolve Studio. Only current project work files will be on computer on which I will work in DaVinci Resolve Studio. Archive files I will store in NAS or another computer with RAID.

Variant 1. On computer for DaVinci Resolve Studio one SSD: M.2, PCI-E x4, NVMe.
Two logical disks on it: disk C, disk D.
Disk C: Windows 10 Home 64-bit, applications including DaVinci Resolve Studio.
Disk D: current project work files.

Variant 2. On computer for DaVinci Resolve Studio two SSDs. Each SSD: M.2, PCI-E x4, NVMe.
First SSD. Disk C on it. On disk C: Windows 10 Home 64-bit, applications including DaVinci Resolve Studio.
Second SDD. Disk D on it. On disk D: current project work files.

What is better for DaVinci Resolve Studio's performance, stability, data safety?
Variant 2 is gonna use 2 SSD Simultaneously, Which means IF one SSD can read Data upto 500MB/s then Both of them is gonna use Double that!
Feels Awesome, right?
But, That is not the fact.... Disk C is Only Gonna Send Huge Amount of Data to RAM when A Software Located inside Disk C is Starting.... When Finished loading It's Gonna be Back to It's idle mode....


That 1-3MB/s Doesn't Really Matter at all to The scale of 500MB/s.
So You can go with 1 Big SSD rather than 2 SSDs.
I would Suggest Doing that, You can Save Some bucks!

Also in my case, I was Downloading a File in Disk C. That's Why it Jumped to 14MBp/s But Usually, Even when Resolve will be Running Speed will be Jumping around 1.8MB/s
I was Worried about Performance Just Like you, Months Ago... I changed my build, Switched to AMD R9 then... My Solution was... Giving the SSD it's Very Own Disk rather than Storing C:Local Drive On it! i Store Local drive in HDD, all The Small and Not-So-Performance-Needed Software in there... The Softwares on which I needed Performance (eg: Blender, Cinema 4D, Fusion) I Installed them inside a Folder In Disk X (Disk X is on SSD)
