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. NVME to 6 SATA ports: https://www.aliexpress.com/item/1005004263885851.html
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!!
