Cost is the biggest thing. I've had one for 8 months and yet to have a problem. It holds 4 drives and isn't too loud. Hot-swap doesn't matter to me (99.5% uptime is sufficient for my needs) and it's not shown itself defective.


Loaded up VMware ESXi 8.x ISO via Remote KVM IPMI and installed without an issue for an Asrock AMD R9 5900X build.


Review by "Cisco Engineer" should be ignored, he/she did not install the screws in the correct orientation. The screw heads should be on the inside of the rail and the nut on the outside, then the rails will not catch on the screws as they slide. Smooth action and strong. Can pull 4U case all the way out of the rack and at nearly 50lbs, the rails stay straight and slide smooth all the way. Not staying these rails are the best out there, but for the price... They fit the iStarUSA D407PL-DE6BK case with ease. Installed into an APC AR3107 (square holes), they provide the square-out washers.

Included all of the screws I needed for the install. Fit right into the rack.

Works as designed, allowed me to install Win 11 on an ASRock AM4 MB

* easy to install * performs as specified with both Windows 2019 Hyper-V Server and Debian Linux

- Very nice construction. - As already mentioned, they are Ball Bearings.- Very simple to put together.(Guide included with pictures)- Universal and easily adjustable.


seamless integration with bitlocker, a built in windows 10 pro feature. I know there are ways to bypass getting a TPM to encrypt your data, but this was affordable and was mostly curious.

Smoothed edges, solid construction, minimal parts list.


Solid rails, quick attach, sweet.

Nice cheap rails

I purchased this cage in December of 2014. It's been installed and working good since then. I haven't had any real issues with it. I have had an issue a few times where it doesn't seem to recognize the drive when the drive is "hot-inserted," but it's always turned out to be a drive or motherboard issue. These cages are, for the most part, fault-proof. It's more or less a passthrough, providing a seat for your drive, and a SATA port to connect to your motherboard. I like the key lock feature, though it won't deter anyone who really wants your drive; it's a tamper feature. Also has an on-off switch for the activity light. I like the option, and it works. I really like how cool it keeps my drives when in use. I have a Corsair 750D case, with vents up on top of the case -- and that has something to do with it, I'm sure; but even then, if I placed the same drive in one of the 750Ds cages without a fan blowing air on the drive, the same drive would reach an extra 10-15c. It's the snug fit, the aluminum used on the sides, and the open top and bottom space that does the trick; though, place something directly on top of this cage, and I wouldn't count on the same cooling effect. For those wondering, it's made with real aluminum, and not plastic with an aluminum-looking film.

super easy to install, worked right away (i bought 2 of them)


Enterprise grade at consumer price
