I have a 2017 iMac (27-inch, 1TB SSD, 4.2GHz Intel Core i7, 40GB Memory, Radeon Pro 580 8 GB) that has two Thunderbolt 3 ports and four USB 3.0 ports. I want to purchase a RAID 1 setup to archive photo/video files. Is there any reason (other than daisy-chaining) as to why I would purchase a more costly Thunderbolt 3 RAID 1 setup instead of a USB 3.0 RAID 1 setup?
I've tried to research this within the forums and on other sites and I haven't found a satisfactory answer to my question. I understand that rotational discs are the bottleneck for read/write speeds rather than the peripheral connections, but manufacturers are selling/marketing HDD Thunderbolt 3 drives. Why would anyone buy those (other than for daisy-chaining)? Are there any performace advantages that a Thunderbolt 3 HDD would have over USB 3.0?
I've been eyeing 12TB 7200rpm RAID setups by LaCie, G-Technology and OWC. Any guidance would be greatly appreciated so I don't unnecessarily spend an extra $200+ for Thunderbolt 3.
