SSD M.2 NVMe for OS or for work drive

I would recommend partitioning the M.2 chip/drive, with something like 100 to 150 Gb for Windows (maybe less, for OSX.x; don't know), and the remaining capacity (on a 500 Gb or 1Tb chip/drive) for files. Then, use that second partition/drive for everything relating to any active videos, by temporarily storing for any video and audio files you are actively using, on that M.2 chip/drive. That definitely has speeded up my work.

An almost-as-good solution -- shift any active video and audio files to an SSD drive, which are substantially faster than spinning drives.

I'm also about to try moving ALL my temp/swap file locations to a TEMP folder, on the M.2 chip (i.e., to the partition with MY files, not the operating system) . Do that by creating the folder (I prefer a name such as 0-TEMP, where the zero moves it up to the top of any list, to remind me I need to clean it out when finished with a project), then using:

Edit/Preferences/Scratch Disks,

and then designate every single option as the new temp folder on the M.2's "files" partition.

Since I was VERY pleased at the results, after I moved a couple of desktop computers to partitioned SSD drives for both system and work files, and even MORE pleased with how gosh-darn fast that M.2 machine became, I've going to start a separate thread on that subject. There's some good software (and practices) that non-IT-experts should know about, if and when they are pondering that step. That thread is here:
