Yes, that should not be a problem, normally RAID controllers support the possibility to add drives to the array later. It just takes a while. Here you can find the manual for this product:

Under Linux, the disks appear in the ICY BOX as normal devices (e.g. /dev/sdb for the first disk, etc.). SMART also works with the usual tools (e.g. entering "smartctl -i /dev/sdb" confirms that SMART is supported and active).
Hello
Attention, as Walter has already written.
I think it depends on which system you are running it on... But to make a RAID with 4 disks out of 2 disks is, e.g. on a Synology NAS, not so easy... The NAS recognises it as an external drive and not as an internal pool.B on a Synology NAS is not so easy possible... The NAS recognises it as an external drive, and not as an internal pool or like if you connect it as an extension via DX517 for example... So it would be easy possible... But here just my hint, if you connect it to a Syno...
I don't know!
I read something about 80 TB in another box. That was an 8-slot tower. I wonder if there is a maximum of 10 TB for each slot? To be on the safe side with specifications, I usually consult the manufacturer's site. This also gives you a feel for what is currently state of the art.
I can't imagine that this works and I can't find a hint in the manual. I assume that the box has its own logic for reporting hard disks as defective and hope that this does not happen at the last minute. But it seems to me that the whole thing is hijacked from the outside.
I don't know what you want to do with the unit. But it is not suitable for permanently changing disks. I use the ICY BOX IB-121CL-U3 for that. They are available for 2 or 4 slots. However, the IB-3640SU3 can be configured for Raid - Raid5.
As far as I understand, this means the connection in the third picture. Since the ICY BOX has USB 3.0, these interfaces can achieve a transfer rate of up to 5 Gbit/s and since older systems do not have USB 3.0 and USB 2.0 would be much too slow, SATA-2 was chosen as the external connection.
