hi to all users of scratch discs 🙂 this is an old one, but may i summarize the subject for 2021, as i use scratch discs on a daily base and my RAM is full early (16GB and on another mac 64GB in the moment). i also need a scratch disc for 4k video work with adobe premiere pro CC. this article is a good recommendation by adobe: (wasnt allowed to post html link:) "adobe > help > scratch disc" or " Set up scratch disks" i just dont see, what a network drive is. ethernet? or even an external thunderbolt raid? ("dont use network drives as scratch disc", they write). apart from that, adobe says, performance is better, if you DONT set your scratch disc.. - to the internal boot disc and work disc, where your huge photoshop files reside, - to an USB2.0 or USB3.0 external 2.5" disc (too slow) (so, i cannot use my fast internal macbookpro 1 TB SSD, if i want max. performance of my scratch disc) so, what is the best option for a scratch disc with maxium performance? in my opinion, a separate and internal SSD, which is dedicated for photoshop only, and always free. (no files on it). point. as my macbookpro laptop has no space for a second internal SSD, i only could opt for an external thunderbolt 3 SSD or HDD raid0, which is also permanently empty (no files on it). how large should a scratch disc be? depends on your files and work method, my files are up to 40GB per single .psb (in 16bit) and i use 24 history states: multiplied, the scratch disc should be 1-2 TB ? not sure... what do you think? thanks for your time.
