I'm settling in with our new 27" iMac, 1TB SSD, originally I was going to use a SamsungT5 1tb external drive for the photo library (600GB now) using it's lifespan and speed to make Photos run nicely (light PS Elements use) . But the Lacie pro drive is an USB-C enterprise drive with a 5 year warranty. The larger Lacie would get gobs of extra storage for future photos and Videos, Dvd's etc. which would keep the iMac "lean and mean" So....Both are USB-C, the list price is the same...199.00 ....1TB vs 4TB,.....SSD vs Enterprise spinning disc,....3year warranty vs 5 year warranty......any thoughts?
