Today we've got the Silicon Power Diamond D10 USB 3.0 portable hard drive on the BCCHardware review bench.

Before we get started let me tell you a little more about Silicon Power. Silicon Power was founded in 2003 and has quickly started to make quite a name for themselves. In 2009 they were ranked #11 among Taiwan's Top 1000 manufacturers and were even ranked #1 in Taiwan's semiconductor industry. You might not be familiar with the name of Silicon Power yet but if the last few years are any indication you might be hearing (and seeing) their name much more frequently.

Now let's get back to the Diamond D10 USB 3.0 portable hard drive. The Diamond D10 line from Silicon Power features hard drives in 500GB, 640GB, 750GB, and 1TB capacities. We're going to be taking a look at the 750GB version and ours has come in a stylish blue finish (the Diamond D10 line is also available in Pink).


First Impressions:

Like with any USB hard drive there isn't really much to see so this section is going to be nice and brief. Just like every other portable USB drive the Diamond D10 is a rectangular enclosure with a hard drive inside, pretty basic stuff.

The first thing you are going to notice on the Diamond D10 is the nice blue finish (also available in pink). This finish is a nice change from the tradition black enclosures that pretty much every company offers.

The Diamond D10 only needs one cable to operate as it draws power and data both through the USB port. This is obviously a pretty nice feature as no one really wants to carry around a power brick with them like other 3.5" portable hard drives require. Thanks to the lower power used by the 2.5" hard drive contained inside the Diamond D10 they are able to power it fully off the USB power.

In the past you used to have to choose between the lower capacity, and more portable, 2.5" enclosures, or the higher capacity, and less portable thanks to the external power supply, 3.5" enclosures. Now with enclosures like the 750GB (or 1TB) Diamond D10 you can get both capacity and portability.

Now this wouldn't be BCCHardware if we didn't open up this device and see what's inside. As you can see in the next set of pictures the Diamond D10 contains a 750GB Western Digital Scorpio Blue hard drive. This is obviously a standard 2.5" hard drive.

So there we go, as I promised earlier, a very brief look at the Diamond D10 USB 3.0 enclosure from Silicon Power. We'll move into the next sections and see if this drive can perform or if it's all show and no go.

Silicon Power Diamond D10 USB 3.0 HDD - Testing:

For testing of the Diamond D10 we ran 2 sets of tests. First off we did a set of synthetic tests using HDTune. HDTune will give us a pretty good idea what speeds this drive is capable of and gives us a high, low, and average reading.




For the chart above I have included both a USB 2.0 and a USB 3.0 reading to show you just how much the performance increase of going to USB 3.0 really is. If you have a system capable of running USB 3.0 a drive like this is a great idea as it will dramatically cut down on your copying time.

If you would like another point of reference for the Diamond D10 you can refer to our previous review of the Zalman ZM-VE200 external hard drive (review can be found here). When comparing the HDTune results with the Zalman we find that the Diamond D10 is very competitive and the only thing that is able to beat it in those tests was a desktop HDD in an eSATA enclosure. It is pretty good overall performance when a 2.5" hard drive can compete with a 3.5" drive in an eSATA enclosure.

For the next set of tests we'll try some "real world testing". Basically in this set of tests we are mainly doing file transfers of difference sizes to show just how fast this drive is. Just like in the synthetic tests we've included results when using the drive in a USB 3.0 port as well as in a USB 2.0 port.


Once again when we compare the performance from USB 2.0 to USB 3.0 the results are pretty shocking between the two. If you're doing a ton of file transfers you'll obviously want to make the move to USB 3.0.

The results are also very impressive when you consider that this is a 2.5" "laptop" drive which in the past haven't always had the best performance. Now thanks to the Western Digital 750 GB drive the Diamond D10 contains and the use of USB 3.0 we are seeing some very decent speeds and you won't have to sit around for hours waiting for your backup to complete.


Silicon Power Diamond D10 USB 3.0 HDD - Software:

I'm not going to go too much into the software side of the Diamond D10 but I wanted to at least show off some of the features that come loaded onto the Diamond D10 with their "SP Widget".

No installation is necessary of this software, just click on the software and you're ready to go.

In the SP Widget you'll find everything you need to get your files backed up very quickly. Even someone not very familiar with backup software shouldn't have any issues using this software.

Primarily the SP Widget features backup tools that will let you customize what you want to backup, but it also lets you encrypt your data on the Diamond D10 which is never a bad idea in the case that you accidentally lose your drive or it gets stolen. With data encryption whoever ends up with your drive will be unable to access the data on this drive without your password, keeping your data nice and safe.




Also you'll notice on the bottom of the SP Widget you'll get a visual display of how much space you have left and how much spare you are using on your drive.

There we go, software and performance testing is complete, let's move onto the final section where we award the Diamond D10 a final score and recap our thoughts about this product.

Silicon Power Diamond D10 USB 3.0 HDD Final Thoughts:

When Silicon Power shipped me this hard drive it was the first time I have ever touched one of their products and I really didn't have any idea what to expect. Like most everyone else I've used and owned at some point it time portable hard drives from big hard drive companies like Seagate and Western Digital and I was very interested to see how a lesser-known (in North America at least) name like Silicon Power would be able to compare. In the end I was pleasantly surprised to see how a portable hard drive like the Diamond D10 was able to do everything that the other guys can do, but at a much more affordable price.

Unfortunately with a portable USB hard drive there really isn't a whole lot to set one product from another. Most companies are using the same hard drive and they are also using the same interface (in this case USB 3.0) so the difference between companies is sometimes very small. What I can say about the D10 from Silicon Power is it offers you everything everyone else does but its going to do it at a lower price without having to give up any options. At the time of publishing you can find this drive online for ~$80.00 USD which is a great deal for a speedy and portable hard drive (Silicon Power also offers a 1TB version of this drive and that can be found for ~$95.00 US online at publishing time).

The software behind the Silicon Power D10 is pretty decent and is more than sufficient to get your files backed up quickly. I wouldn't say the software included is the most advanced software out there, but I found it very easy to get everything setup and running like I wanted without having to read the manuals.

At the end of the day it is very easy for me to recommend the Silicon Power Diamond D10 USB 3.0 portable hard drive. The fact that it feels well built, works like advertised, and is a very good value has easily earned it our "Editor's Choice - Gold" award.



  • Good Performance Thanks to USB 3.0
  • Only One Cable Needed
  • Good Quality Construction



  • Nothing Major
