Pricing and Conclusion
The ICYRaid is a decent price given its hardware RAID features and performance. The ICYCube's pricing seems high given its limited feature set (only JBOD), especially since it falls ~$75 short of a 4-Bay 3rd generation Drobo, which runs circles around it on features. We did note some negative Amazon reviews on the ICYCube, but we did not experience the same behavior on our sample.
I was impressed with the build quality of these two drive enclosures. They are reasonably durable and should have no issue safely containing drives. Their solid anodized aluminum shells are not bad to look at, either. The ICYRaid has simple hardware RAID features easily selected by a rear panel switch, making configuration a no brainer. The ICYCube only operates as a JBOD unit, meaning those desiring RAID are going to have to rely on software-RAID features of their OS (as well as the corresponding performance hit when using a software RAID through a single external interface link).
A nice, simple two bay RAID enclosure that is quiet and easy to configure.
Good build quality, but limited on features for such an expensive device.
