I just ordered the 2019 iMac with i9 vega 48 and 512G SSD. Since I'm editing videos on the machine, I'm looking for a external SSD solution. Option1: Samsung T5 1TB for around $190. Speed capped at 500MB/s. (or sandisk/WD counterparts) Option2: Samsung PM981 1TB and a nvme SSD case with USB3.1 gen2 for a total of $300. Speed capped at around 1000MB/s I don't paticularly want to opt for a thunderbolt 3 SSD option cuz that price would be way too steep for me. What do you guys think? Does samsung offer good firmware updates?
