ARC-8050T3-24R expander firmware supports the ability to spin up the disk drives sequen­tially or in groups, allowing the drives to come ready at the opti­mum time. But ARC-8050T3-24R cannot meet the short start up time on the Mac studio m1 max when expander firmware selects the sequen­tially spins up the disk drives option. This issue can fix by setting the option to spin up the drives in groups from the “Spin Command” on the expander firmware.
