Rosewill RSV 4 x 3.5-Inch HDD Cage RASA-11001

Good product, excellent performance. I will be buying more.

Fit my case perfectly with easy enough cable access and sturdy feel. Running 4x 4TB drives with this using ZFS and it's worked like a charm! No issues recognizing drives or reading/writing data. Cables can be routed through the back of your case with the SATA connections being toward the rear of the case, so **REMEMBER TO PLUG IN SATA CABLES BEFORE INSTALLING** if you want to save yourself some tricky angling trying to plug them in after the cage is installed.

Fit like a glove in a Chenbro RM42300 4U server chassis. Other review complaints about the plastic drive trays are way off base. The trays are well made and (to me) they seem better that some of the comparable "enterprise grade" trays I've used from Tyan and Supermicro. If you're swapping drives often enough to break or wear these out, you need to get better drives or invest in an external eSATA drive dock. The other common complaints - molex power connectors and connector location - are really only relevant if you're putting this in a desktop. In a server chassis, connector placement is perfect. And the clunky old molex connectors are more mechanically secure than SATA power connectors. Overall, I think the quality is fantastic for the price. This has to be one of the best values in server components I've seen in a long time. I prefer the trays over trayless designs and the fact that they're designed to accommodate both 3.5" and 2.5" drives without an adapter shows good attention to design. Cooling is the other area where this unit excels. There is good provision for airflow (within the size constraints) and the 120mm fan runs at a sane (moderate) RPM for nice quiet operation while still moving plenty of air. I can definitely say these drive cages are going to become a standard feature in all my server builds.

This works and easily provides the space I needed to install four more drives. The fit was fairly tight in the first case I used this in (so much so I was concerned I wouldn't be able to remove it), but I was able to transfer it to a Rosewill Thor NAS when I upgraded with no issues whatsoever. One concern I did have was that only a month of use and I'm having issues with the status lights. The top one seems to have burnt out completely and the bottom one won't turn off or flicker. That being said, it has not affected the functions of this enclosure. My drives all work perfectly fine and my temps are very well under control. Aside from the failing LEDs, this has been a great drop in fix for my needs.

This is exactly what I was looking for. Sturdy and adds rigidity to the case. Fits with slight modifications but worth it.

For a PC case you buy on a consumer level it will probably fit. No offense to any cases/case manufactures but they add extra tolerances for cheap hardware like this. It does not meet the requirements for a 5.25" bay though. I've tried this in multiple high end workstations/servers now (poweredge/HP workstations/ect) and it will not fit in any of them. The metal cage itself is fine and does fit. The plastic extrusion on the front and the back absolutely will not. Where the plastic is attached to the metal with screws the plastic sticks out past the cage. The faceplate is just blatantly not even with the sides or close to the right size. If you can force it in past the back plate the front plate will never fit flush because it is not the correct size. The front is the correct size but it expands out to the point it's not able to fit. You might be able to get away with leaving it sticking out but the screws won't line up. If you're willing to put a little muscle into it (and have a case cheap enough to bend) you can get it flush. It's a real shame because it works just fine. It's just the cheap plastic they engineered wrong and couldn't spend a penny to fix that makes it garbage.

A very nice backplane. The fan is quiet and its well made. The ports are on the same side as the motherboard so it's best to connect the SATA and power cables before installing. my drives are staying under 40C during backups.

I've had this running for over nine months. This is an excellent piece of hardware to convert nearly any commodity PC case into a NAS. I see a lot of commercial offerings for home NAS systems and they typically seem to be overpriced for what they deliver. I always suggest to people to "roll" their own using a piece of hardware like this and LINUX. Of course not everyone is receptive to that option, which keeps companies like Synology in business. Update: Five years on and starting to have problems with the back plane. Bottom drive (HDD4) starting clicking and dropping off line, had bad sectors and was getting a bit old. Replaced it with another hard drive (called HDD5 in this case)... same issue. Put HDD5 in USB case to test, everything works fine. Replaced SATA cable from MOBO to back plane.. issue again. Bypassed back plane power+SATA to HDD5.. everything works fine. I would buy another one of these HDD Cages but may look for an alternative brand/solution before doing so. Just be prepared to add another factor into troubleshooting issues with this item. At least this thing didn't toast all four hard drives out of the box like what happened with another reviewer.
