Seems not to work in Dell Dimension Desktops

By: nvgoldendog - 12/05/2016
When I install this into a Dell Dimension Desktop with a Crucial MX 300 275GB SSD, the computer will lock up. If I plug directly into the drive without this device it seems to work fine.

Nice product- well built

By: Macphoto - 01/30/2017
This is a fantastic item for anyone who needs to use a 2.5" drive in a 3.5" bay. I used this item using an 512GB SSD. The 2.5" drive slides in effortlessly and makes connection with ease. I tried to remove the drive using the release and it had no issues ejecting the 2.5" drive from the case. I took the drive and placed it into my iMac which requires a 3.5" drive and it worked perfectly. This is great for these older legacy Macs without having to use fancy specialized adapters. The product build is excellent and I look forward to a speedier iMac. I received this product in exchange for an unbiased review

Great solution

By: NickD_CA5 - 02/05/2017
I have been using this device from time to time over the past few weeks. I have tested this with multiple 2.5" drives and in different computers and drive duplicators. This product comes in a nice little box, just slightly bigger than the enclosure itself. It has instructions which I don't think are necessary (very self explanatory) as well as screws for permanent mounting in a computer or drive tray. The enclosure is very light and I almost thought that the shipping box was empty until I shook it. There are many ventilation holes along the bottom to allow air/heat to circulate. When a drive is inserted in the enclosure, it does not actually make a connection until the door is closed and the 2.5" drive is pressed into place. When the door is opened, it ejects the drive and lifts it out of the enclosure. This is very well designed and works smoothly. I am able to even remove and add disk into the enclosure while connect to a computer and the drives are automatically detected. The enclosure is the same size as a 3.5" drive and has the same screw holes so it can be secured anywhere any 3.5" drive can be secured. It looks like it just passes through the SATA port, so I don't think I will see any compatibility issues with any disk/computer. What a great product, another StarTech "must-have IT gem". I received this product in exchange for an unbiased review.

Totally Useful Drive Adapter

By: ShaunOntario - 02/16/2017
I got this a few weeks ago to solve a form factor problem. My desktop had the rails for a 3.5" drive only, and I have a higher quality/high capacity 2.5" that I wanted to use and this solved the issue. It's size is that of a standard 3.5" drive in which a 2.5" fits. You slide the red button to the side and the spring loaded door opens. Once a 2.5" drive is placed inside, the door guides it in. The product came with suitable instructions and small screws to attach it to the computer's rails. I think a small 'hint' printed on the door that opens would be useful for those of us that rarely read instructions.

Great for MacPro upgrades

By: David CA - 06/11/2018
I used this adapter to upgrade the system drive in an old aluminum MacPro to an SSD. Very easy to install and it works great. One caveat: the mounting threads are simply cut into the sheet metal of the base and they are easy to strip, so be gentle with your screwdriver!

doesn't work!

By: Cherokee - 05/01/2019
I bought two of these today from Memory Express in Calgary. They will be back there tomorrow! My wife has a HP Pavilion (I know.... not even mediocre!) with a M2N68-LA "Pegatron" Mother Board. In the caddy (adapter Enclosure!) the PC won't start and tells me there is a problem and I need to repair my system... I connect the SSD directly i.e. no longer in the caddy... and all is well ... boots up as normal. I tried the other Adapter Enclosure that I bought... same thing! Neither works with HP or this particular board. I just hope I get my money back from Memory Express!
