Get a thunderbolt 3 or USB4 (40Gb) enclosure and stick in an 8TB SSD stick. Inland (Microcenter) makes a decent QLC model. Expect to pay about $1250 total for all of this though.
How does your Studio edit the A1 8K footage? In editing 4K HEVC from my A7S3, our Ultra 48C is barely faster than the Max 32C. At best about 30% on effects laden edits, and rarely faster on export. That‘s with heavy edits layers Multicam effects etc. Great for the laptop but Ultra seems overkill for the desktop.
For 8K though….?
