While the Mac Pro® (2019) offers fast 3,400 MB/s internal SSD storage, capacity is limited to 8TB. Connecting external drives is an option, but why not just use the space and connections inside the Mac Pro to add capacity? Sonnet’s Fusion™ Flex J3i makes it easy, enabling you to securely install and connect up to three SATA drives (sold separately) in the available space next to the PCIe card slots.

Sonnet designed the Fusion Flex J3i to make maximum use of the space and connections inside the Mac Pro; constructed out of heavy-gauge aluminum, the J3i looks right at home inside the computer. Shock and vibration isolators for 3.5-inch drives protects each drive from cross-coupled vibration from the other, safeguarding against read/write errors and retries. Mounting plates for 2.5-inch drives are included, so there’s no need to purchase separate pieces to use them. Custom power and data cables deliver a clean look to the installation.
