Add up to 52TB of Storage!

Mount up to Three SATA Drives in Your 2019 or 2023 Mac Pro

While the 2019 or 2023 Mac Pro offers fast internal SSD storage, capacity is limited. 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.

Install Two 3.5-inch Drives (up to 20TB x 2) Plus One 2.5 SSD (up to 8TB)

Not only does the Fusion Flex J3i provide support for mounting two 3.5-inch hard drives of your choice, the Flex's custom design provides mounting support for an additional 2.5-inch SATA SSD. Of course, the necessary mounting hardware and connecting cables are included for a clean installation.

Or Install Three 2.5-inch SSDs

The Fusion Flex J3i includes mounting plates and screws that enable you to install three 2.5-inch SSDs in total.

Rugged and Custom Design

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.
