I have just upgraded my internal 8 x 3TB WD Red drives in my system and wanted to look at using these drives in an external 8 Bay enclosure only needing Raid 0 - as it will only be used purely as a backup device. I've looked at RaidSonic's ICY BOX IB-RD3680SU3 - which sort of looks OK. The only thing I'm not sure of is whether it can be stacked with another external enclosure should my backup requirements change. I'm currently running 24TB in a Raid 0 config made up of 2 x 12TB Seagate IronWolf Pro. I have about 4TB free but when that starts to run out, I would like to think I could expand both internal raid array (running off Gigabyte X470 Gaming 7 WIFI mobo) as well as external raid array by adding another enclosure and more disks (I.E., can I get a single raid to extend across multiple external enclosures?!?
