### ⭐⭐⭐⭐⭐ High quality 5-in-3 trayless hotswap cage
*by A***W on October 18, 2013*

I purchased this iStarUSA 5-in-3 trayless hotswap cage to add 5 more drive bays to my Supermicro CSE-743T-500B case. It fits this case very well. One thing to keep in mind is that this particular drive cage is not compatible with cases that have the metal tabs at the bottom of each 5.25" bay. I've heard of others bending these tabs on their case to make it fit, but fortunately Supermicro made the tabs spring-loaded.I did have trouble getting my metal icydock 2.5"-to-3.5" adapter to fit in one of the slots, but the cheap plastic version worked fine. The metal adapter wouldn't insert fully in order to get the door closed on the hotswap bay. I'm not sure if it's the fault of the adapter or the hotswap cage. All of my other 3.5" SATA drives fit fine.The hotswap cage seems to be quite sturdy and feels well-built. It's made of aluminium and has aluminium doors with locks to keep the the children from accidentally ejecting the drives. I'm sure the locks won't keep someone out that's determined, but at least it provides some level of security against accidental drive removals.I can't comment on the fan since the 4 80mm fans on my CSE-743T-500B case are louder than this fan is with the 'low' speed selected. Also, with this case I could probably get away with removing the fan altogether since it has such strong front-to-back airflow already.In all, while fairly expensive, I would recommend this hotswap cage over the other options on the market and I would buy it again.

### ⭐⭐⭐⭐ Appears to be good quality but wow, the noise
*by T***N on August 14, 2016*

Its not a bad unit, but two big things for me was noise and noise. The included fan is crazy loud, even on the low mode, so to fix this I replaced it with a noctua unit (not a drop-in option so had to get creative). Then there was still a lot more noise than before adding the hot swap cage, it was the hard drives as its metal to metal. I really good cage design IMO would have some kind of rubbery lining or construction, but this is all metal and the HDDs were creating a lot of noise so to fix this I put electrical tape along the edges of the HDDs. So now after replacing the fan and lining the HDDs, finally the computer isn't audible all throughout the house. Another nice design addition would be filtration capability. I suppose for the money its a good unit and thus the 4 start vs a 3 star- with a lack of what seems to be any units that are better one just has to make a unit like this work. Eventually SSDs will be so affordable the only issue will be fan noise on units like this and that is pretty easy to fix.

### ⭐⭐⭐⭐⭐ Very nice enclosure.
*by D***N on June 30, 2015*

I am very happy with this drive enclosure. The enclosure looks very nice, feels very solid and so far runs fine in my home ESX server running RAID 6 with an LSI controller. I would think the only thing that would ever break on this (other than the fan) might be the little tab that keeps the doors closed (knock on wood).One more very nice feature of this enclosure is that your HDD slides in with no special rails or caddy. I will upload a picture of my enclosure installed with a drive sliding in.p.s. This enclosure mounts with the drives vertical as shown in the picture, however, I believe mine is mounted upside-down (this was done because it was the only way my drive mounting rails would line up).
