The Trans International Pro Caddy V provides a way to add multiple HDDs (and SDDs) inside the 2019 Mac Pro. This article features three striped HDDs.

Power is provided by a connector cable array that plugs into the power port on the backplane. The data connectors came from a cable plugged into the ARECA ARC-1883ix-12 SAS RAID controller installed in an x16 PCIe slot.

Trans International makes six different Pro Caddy Vs designed to hold various types of drives. Back in September 2020 we tested with 10 SSDs which produced READ speeds as high as 4084 MB/s and WRITE speeds as high as 2921 MB/s.

Though we used 8TB HDDs in this test, you can purchase 18TB HDDs ($600 each) with speeds up to 227MB/s each. There are also 18TB SSDs ($2700 each) with speeds up to 2100MB/s each.
