Hi - My Quadra 840AV currently has a BlueSCSI V2 as it's boot drive, and I am thinking about adding a Atto SiliconExpress IV to interface to the BlueSCSI Ultra Wide. Any thoughts or advice?

Anything you’re looking to know? Should work fine and be faster. But the wide only helps a tiny bit over any fast narrow (afaik benchmarks should be similar): https://68kmla.org/bb/threads/maximum-siliconexpress-iv-throughput.51369/

But if the AV really is faster on a wide, I’d love to know.

That thread indicates that result may be an issue with the 650 vs AV nubus controller. if I get it working I will let you know the results are.
