It's unbelievably hard to find external 2,5" 2-bay RAID enclosures, but apparently it's impossible to find such an enclosure with hdparm/udisksctl support. I just want to spin down and power off the drives in the enclosure from a Linux shell (e.g., udisksctl power-off -b /dev/sdb). I already tried ICY BOX IB-RD2253-U31, without success.
Is anybody aware of such an enclosure?
