Thermaltake VI-ON USB & e-Sata Drive Enclosure

The Thermaltake VI-ON 3 1/2 inch USB & e-Sata drive enclosure not only provides external storage but does it with active cooling and won’t “Ugly Up” your desk.


External storage for computers comes in so many different flavors it’s hard to make a choice. Unfortunately, many of those choices don’t include Active Cooling for the hard drive. Many of the external HDD enclosures provide the functionality you need, but are utilitarian in design and tend to “ugly up” your desk. Not only do they raise the “ugly” factor of your desktop, they seldom have Active Cooling for the hard working drive inside, and Active Smart Cooling is pretty much non-existent.

At least until now, Active Smart Cooling for HDD enclosures has been ignored. Thermaltake decided it was time for Active Smart Cooling in HDD enclosures and came up with the Thermaltake VI-ON. The Thermaltake VI-ON brings style to the never ending parade of external HDD enclosures, and raises the ante with Active Smart Cooling.

VI-ON Un-Assembled

Without even assembling the VI-ON you can already tell that it’s not going to take up much space on your desktop and it’s not going to be painful to look at.

VI-ON Assembled

With the VI-ON assembled, you can really see it’s designed to be easy on the eye and the footprint of the VI-ON is designed to take up minimal space.

On the back of the VI-ON you can see (Top to bottom) the USB connector, the e-Sata connector, the DC Converter port, and the on/off switch.

The Bundle

In the box along with VI-ON you’ll find an AC to DC converter, a USB cable, an e-Sata cable, and a cleaning cloth. If you handle the VI-ON you’ll need the cloth because it’s shiny surface picks up fingerprints easily.

The Papers & Manual

You’ll also find a Operating System Specific quick start guide and Manual. Setup was simple enough that we didn’t have to crack the Manual open. Just slide the drive into the enclosure and connect it to the computer, switch it on and your up and running.

To test the Thermaltake VI-ON we ran HDTach in both the USB and e-Sata modes available on the enclosure. We ran the test three times, and of those three runs the average was reported. The HDD used to run the test was a 400GB 16MB cache Western Digital Sata II HDD.

Test Results

Hard Drive Tach
32 MB Test

  USB e-Sata
Random Access Time* (ms) 15.1 14.7
Average Read (MB/sec) 27.54 107.2
CPU Utilization* 2% 2%
Burst Speed (MB/sec) 29.71 121.6

*Lower is Better … Otherwise Higher is Better

In USB mode the VI-ON transferred at 27.54 MB/s, which is actually a little better than most USB interface enclosures we’ve tested. It turned a 15.1 ms access time, and the burst rate climbed a little to 29.71 MB/s. That’s pretty good considering it’s a USB interface. On average we see about 25 MB/s average read on most USB enclosures.

In e-Sata mode things got quite a bit faster. The VI-ON came in at 107.2 MB/s average read, with a 14.7 ms access time, and a burst rate of 121.6 MB/s. It’s not quite as good as an internal hard drive, but it’s pretty respectable for an external. For data purposes both the USB and e-Sata modes would be acceptable. The e-Sata mode would make imaging your operating system drive a snap and you’d always have a backup of your operating system and files.


Thermaltake managed to bring a little style to the table with the VI-ON, then threw respectable speeds and access times in with it to boot. Setup was a snap and we didn’t even need to open the manual to accomplish it. It’s footprint was the smallest we’ve seen in a while and it was easy on the eye. The top portion of the VI-ON is removable for easy mobility and is a nice added feature.

We took the temperature of the HDD utilizing Active Smart Cooling during extended data transfers (copying an entire DVD to the drive). The temperature never went above 43°C, with an average of 42°C. For comparison, we used an un-cooled Sata drive enclosure and the temperature during the same data transfer peaked at 52°C. The VI-ON reduced the operating temperature with it’s Active Smart Cooling by 9°C. The lower temperatures mean a longer life for the drive so the decrease was a welcome sight.

You’ll be hard-pressed to find fault with the VI-ON. Other than fingerprints showing up easily on the casing and the power cord being a little short, we really couldn’t find anything else to complain about.


+  Active Cooling
+  Small Footprint
+  e-Sata & USB
+  Easily Portable
+  Good Transfer Rates
+  Looks Better Than Most Enclosures
+  Vibration Dampening
+  Quiet Operation


  Power Cord A Little Short

The Thermaltake VI-ON transfers data at a good rate, doesn’t take up much room on the desk, comes apart easily for portability, and keeps the “ugly” away from your rig.

Final Score: 8 out of 10 and the Bjorn3D Seal of Approval.
