🚀 M4 Mac Mini 8TB SSD RAID Setup & Speed Test | Acasis Workstation Dock | M002Pro TB1201 In this video, I set up 8TB of NVMe SSD storage inside the Acasis M4 Mac Mini Workstation Dock using two Western Digital 4TB SN850X SSDs.

We’ll go step by step through:
Installation & thermal pad setup
Formatting the drives in macOS
Testing different RAID configurations: JBOD, RAID 1, and RAID 0
Running benchmarks with Blackmagic Disk Speed Test
Real-world file transfer performance comparisons

Finally, I’ll share insights about power, stability, and which RAID option makes the most sense for Mac Mini M4 users who want high-speed external storage.
