Well, nothing is reliable over USB type A. If you don’t want to DIY you can get a USB JBOD with type-c like this one or that one or this cheaper one. They’ll get the job done for a price. :)
However, there are easy ways to get reliable SATA ports from m2 slots that your framework has.
To power the disks you can use ANY standard ATX power supply (get something brand-gold second hand for 20$). To make sure the PSU stays ON, just plug a wire between the green and any black wire.
Another option for power is to get a cheap 12V power supply and a step down DC/DC to provide 5V. If you don’t have it a SATA cable like this is helpful. Simply cut the white plug and attach the red cable (5v) to the output of the DC/DC and the yellow one (12V) directly to the power supply.
There’s also these dual output power supplies that you can regulate to 12v+5v but frankly I would just go for the option above as it will be safer.
Make sure you check every voltage and polarity before plugging anything into your power supply!!
