Portable Hard Drive Enclosures are pretty common place nowadays. Sometimes all you want is a way to cart your files around, but sometimes you want that little something extra, that will set your enclosure apart from the rest. The people at CP Technologies have given us just what we wanted in the CP-USH-300 enclosure. Not only does it carry your data, but it pulls double duty as a hub for your USB devices. Really, you don’t lose a USB port when you use it; instead it gives you two to use right on the device itself. Add to that fact that the software comes preloaded on the hardware of the enclosure itself, and you’ve got that little something extra I mentioned. Click Read More to learn more about this device.

Cost: $29.95

Closer Look:

The packaging for the CP Tech USA CP-USH-300 is professional and cheerful looking. As with many well thought out packages, this packaging displays the unit itself on the front. Several of its features are listed underneath its name, as well as which series it belongs to. Several  small graphics display some of the more notable features, including a secured disk option, the ability to synchronize files and the ability to carry several programs with you for a Mobile Office.

The back of the packaging features another shot of the product itself, as well as more information. This includes Package contents, System requirements, and contact information for CP Technologies itself.  All in all, almost everything you could want to know about the device is listed either on the front or the back of the packaging.

Inside the package there is a large selection of items. Included is the enclosure itself, a cloth carrying pouch, the USB cable to connect the device, a user manual, as well as the two screws needed to seal the device after the drive has been installed.

Let’s continue our tour with a look at the enclosure itself.

Closer Look Continued:

The enclosure is a shiny black on top with matte black sides and bottom. On the back of the device is where the magic happens. Here we have 2 USB ports for use with you other devices, the port for connecting your enclosure to the PC and a 5V DC in. The latter is not used unless you deem it necessary for some unforeseen reason. In normal circumstances the USB connection will power the drive by itself.

The slim profile of the device is seen in the following pictures. On the top of the drive there are 4 LEDs as well as a stop/play button. The 4 LEDs display whether or not the device is powered, the hard drive is connected, or the USB ports are being used. The button is used for quickly accessing your favorite task, a setting that can be customized with the included software. The front of the enclosure curves gently downward, so that the top and bottom eventually meet, making for an esthetically pleasing look to this enclosure.

The testing of the enclosure itself will involve running some low-level benchmarks on it and timing file transfers. For the benchmarks I will be using the program HDTune, a free benchmarking utility. For the file transfers I will be timing the process with a stop watch. I should explain that I could benchmark the actual performance of the drive by using a benchmarking utility, but such programs do not necessarily reflect how long it would take a user to transfer a file in their GUI environment. So in the interest of what results our readers in the real world can expect, we do the file benchmark using a stop watch. I will be comparing the CP-USH-300 to another CP Technologies enclosure, the CP-UE-225. As well I will utilize benchmarks from the Thermaltake Vion. Let’s see how it worked out.

Well you can see that things were pretty close all around. These tests are really to discover any flaws in the design of the enclosure itself, and that doesn’t happen that much. But we do get a good idea of the strengths and weaknesses of our enclosure. It appears that the CP-USH-300 is in the middle of the pack as far as our selection of enclosures is concerned. Though it posted the lowest Maximum speed, it did have a higher burst than the Thermaltake. And on the file transfer test, it actually posted the fastest time on the largest file. These subtle differences can mean a lot to someone in their search for the perfect enclosure for their situation. Let’s move onto the conclusion.


Overall this is a good enclosure. Its plastic construction is a positive and negative at the same time.  It is positive because it is lightweight but negative because it lacks a certain rugged feel. The only other thing that I thought could use some improvement is that there is no room at all in the enclosure for any anti-shock padding. The drive is forced to sit right atop the hard plastic of the case. Again, this is a minor consideration, but those little details sometimes save your HDD from failure. These were the only two things I did not personally like about the enclosure. It was very easy to open and close and installing the drive went smoothly. Don’t rush that step, it could be costly. The included software was easy to learn and did its job very well,  and of course the extra USB ports always come in handy.

Would I buy this product? Yes, I would. It is a good enclosure with a fair amount of bonus features pre-loaded onto it. In my opinion this practice speaks volumes about how a manufacturer feels about their prospective customers. That little bit extra that CP Technologies has put into making this enclosure more than just another electronic brick, shows in the extras they’ve added. I appreciated it and I’m sure you will too.


  • Affordable
  • Lightweight
  • Easy to Use
  • USB Hub



  • Could be More Sturdy
  • No Anti-Shock
