Maybe Jim will give us/me a definitive answer here;
Are SSD drives the way to go for the project/audio drive? I thought there was an issue with multiple read/write cycles with SSD drives.
As to the OS on the M.2:
why waste valuable sample space with the OS?
I upgraded my old Cat to ssd on the OS several years ago, cloned the existing drive, other than the time it takes Sonar to scan the vst’s, I really didn’t see a “blinding” increase in speed.
Jim said I wouldn’t, maybe his optimizations, and keeping things “lean”?
As to size; go 500 if you feel you need it, I’m on my phone so I can’t quiz my Cats as to actual use on my OS drives. I know my 9 year old “office” rig is 250, and it’s not “full” by any means.
Best of luck with your build.
just my nickel98’s worth.
