The aluminum storage device has removable trays designed to house up to four 2.5" SATA SSDs or hard drives purchased separately. The device is equipped with two Thunderbolt 3 ports—the first one connects to the MacBook Pro, and the second one can be used to connect or daisy chain Thunderbolt 3 or USB-C peripherals.
With Software RAID, Akitio said four striped SSDs can reach data transfer speeds of up to 1375 MB/s, while four striped hard drives max out at around 400 MB/s. Thunderbolt 3 provides sufficient bandwidth to connect dual 4K displays to the latest MacBook Pro and complete other data transfers simultaneously.
A dedicated DisplayPort 1.2 video output provides connectivity to the 4K displays at 60Hz, while the device supports Power Delivery up to 15W to notebooks that support charging from a 5V/3A power source. 15W is hardly sufficient wattage for the latest MacBook Pro, which fully charges at up to 85W with Apple's own charger.
