I bought it almost 3 years ago. I use a OWC thunderbolt 3 enclosure. RAID gives me speed of 1500 MBPS. And non raid around 2400. All my drives on PCI max out around 6800. If I bought it today, I will go for thunderbolt 4.What thunderbolt enclosure did you settle on? Do you have a sense of its speed? Do you run it in RAID or JBOD? TIA.
