Sonnet Fusion Flex J3i 3-Drive Mounting Bracket – Product Overview

The Sonnet Fusion Flex J3i 3-Drive Mounting Bracket (FUS-FLEX-J3) uses the available internal space and connections in the 2023 and 2019 Mac Pro to add up to three user-supplied SATA drives without placing additional external storage around the workstation.


Up To Three Internal Drives

The bracket supports two 3.5-inch SATA hard drives plus one 2.5-inch SATA SSD, or a configuration of three 2.5-inch SATA SSDs using the included mounting plates.


Designed Specifically For Mac Pro

Fusion Flex J3i is compatible with Mac Pro 8,1 (2023) and Mac Pro 7,1 (2019), in both desktop and rackmount configurations.


Mounting Hardware And Cabling Included

Sonnet includes two 2.5-inch drive mounting plates, a two-drive SATA data/power cable assembly, a USB 3-to-SATA data/power adapter cable, vibration isolators and the required mounting screws.


Hard Drive Vibration Isolation

Shock and vibration isolators help reduce cross-coupled vibration when 3.5-inch hard drives are installed, supporting reliable operation in professional workstations.


Boot Support Depends On Mac Pro Generation And Connection

On a 2019 Intel Mac Pro, suitably configured SATA- or USB-connected SSDs can be used for boot volumes subject to Apple's external-boot security settings. On the 2023 Mac Pro, Sonnet specifies boot support for an SSD connected through the internal USB port; drives connected to the Mac Pro SATA port are not bootable.
