The Ultimate Internal Storage Upgrade for Your 2019 Mac Pro
Your 2019 Mac Pro is a powerhouse, but its internal storage capacity can be a significant bottleneck for demanding professional workflows. While the factory SSD is incredibly fast, it maxes out at 8TB, and relying on external drives adds cable clutter and complexity. The Sonnet Fusion Flex J3i is the definitive, engineered solution, designed to seamlessly integrate up to three additional SATA drives directly inside your Mac Pro for a clean, powerful, and factory-finish installation.
Meticulously designed to fit perfectly into the space next to the PCIe card cage, the Fusion Flex J3i provides unparalleled storage flexibility. Configure it to match your exact needs: install two high-capacity 3.5-inch hard drives for massive media libraries and archives, plus a 2.5-inch SSD for your active project files and applications. For maximum performance, mount three 2.5-inch SATA SSDs and configure them as a RAID 0 set. This setup can deliver speeds that rival internal NVMe performance, making it ideal for editing 8K video, managing complex multi-track audio sessions, or any task that demands extreme data throughput.
Constructed from heavy-gauge aluminum, the J3i is as robust as it is elegant, perfectly complementing the Mac Pro’s industrial design. Sonnet's commitment to quality is evident in every detail. Integrated vibration and shock isolators protect your 3.5-inch hard drives from harmful cross-coupled vibrations, ensuring data integrity and whisper-quiet operation. The all-in-one kit includes custom-length power and SATA data cables for tidy management, along with all the necessary mounting hardware for a straightforward installation. Stop compromising and start expanding. Unlock your Mac Pro's true potential with the Sonnet Fusion Flex J3i.
