I think CalDigit really missed the boat on the TS5+ (FIVE hundred bucks!) by not including PCIe 4.0/5.0 M.2 NVMe slots. That enclosure could accommodate at least two 2280 drives, maybe three. It has an aluminum enclosure which could easily serve as the heatsink. For $500, It needs more than additional SD card slots to be a must-buy for me.
