Notes:
1. 6302MB/s sequential read/write peak speed based on testing an 8TB OWC Aura Ultra IV SSD equipped StudioStack connected to a Mac Studio M3 Ultra running AJA System Test (4K-Full resolution, 64GB file size, 16bit RGBA codec, single file test). Actual performance may vary depending on the installed drive and the application used.
2. Thunderbolt 5 can support up to three displays from a single computer host port dependent on the host computer's capability. This includes up to three 6K or lower resolution displays, three 8K displays @ 60Hz, or two 8K displays @ 120Hz. Presently, Apple has enabled support for a maximum of two native displays per connected Apple Mac Thunderbolt host port. Software driver based technologies, such as DisplayLink (as supported by the OWC USB-C Dual HDMI 4K Display Adapter), may enable additional display support.
