I'd say Samsung 860 EVO or something similar to its range that writes at up to 520MB/s. Probably won't burn a hole in your wallet as the price point starts around $60. Hopefully, it would speed up your rendering on adobe even while working on something massive. I'm not able to say if the SSD speed alone determines how well photoshop related utilities run smooth. HDDs are also a pretty much convenient option and especially WD. WD has 3 variants that cover major preference that users ought to buy them for. If you're dubious on choosing between an SDD or WD HDD, give it a read before your make your choice. I did go thorough comparisons such as tekhattan's before I chose to buy a WD purple to backup my heap of files.
