Mediasonic 4 x 3.5” and 2.5” SATA 3 / SAS 2 Hard Drive or SSD to 3 x 5.25-inch Drive Bay Mobile Rack Backplane – Hot-Swap / Removable Tray Design / Metal Construction (HT31-304)

Liked the all metal construction. But that is it. The drive trays are. Ot wide enough to hold a 3.5 inch drive. I attempted to mount a 20 TB wouldn't fit, then an 18 TB still would not fit. I tried 20 TB SATA, 18TB SATA, 14 TB SAS, 10 TB SATA, 8 TB SATA, 6 TB SATA, 2 TB SATA, 1.5 TB SATA. All were over 1/16 inch bigger than the tray. I tried to force the 1.5 TB drive into it which forced the tray to flex causing the walls of the tray not to allow the tray to slide into the bay. Also the tray flexed up to touch the the paddle board on the HDD which could short your drive out and possibly blow up the HDD controller. Thrse are completely unusable and will be returned. Tb His design flaw is unacceptable!

Fits as expected within the 3 x 5.25 space, and have not had any issues with the drives that are now within it. Good price compared to other options as well.

The media could not be loaded. Product arrived defective but mainly cosmetic issue where if you walk one of the hard drive base it's still able to be opened. The rest of the hard drive trays work fine and stay locked.

Used it to add a removable drive bay to a server I was building. worked out well. definitely recommend it will fit in standard drive bay that some PCs have. Stan...

Although this cage comes with a burned smell, but 4 bays work very well, I didn’t install the had led, the case is Corsair 750d, as you see I put 12 4tb hdds inside with zfs ,with the cage I can install 4 more, hot swap is great, now the server is so heavy, so better to have big disks , we don’t need too many bays there, if there are too many disks, the air flow is not good just like the left side internal 750d cage, hdd’s temperature easily get up to 50 degree. Cons : the fan included is a little bit loud, louder than my 4 fans in 750d The disk space is a little bit close to each other, The fan is a little bit small Overall good Arrived quick
