CONCLUSION

   It's quite unfortunate that the previous 2.5" Portable Hard Drive we reviewed was the lightning fast Touro Mobile Pro 1TB by HGST so naturally when checking our charts eyes tend to compare that to the Diamond D20 500GB which in turn obviously lags behind in terms of performance. However if you move down the ladder you will see that the Diamond D20 actually does just as well if not better than many other 2.5" portable hard drives. Size is also a factor and since the Diamond D20 is not only smaller than the Toshiba STOR.E. Slim but it also performs better in most tests I’d say that goes a long way in deciding which is best. Of course the housing of the Diamond D20 is not entirely made by aluminum and in that aspect i do prefer the STOR.E Slim more but that is something that always comes down to personal preference. Worth mentioning for potential buyers is that the Diamond D20 portable hard drive is also compatible with the usual and quite useful SP Widget software suite which simplifies the various functions end users can perform.

   As we speak 500GB portable hard drives come quite cheap and so does the Diamond D20 500GB USB 3.0 PHD by Silicon Power since you can find it for USD70.67 inside the USA (Purchase Directly from Amazon.com) and for 61.67Euros inside the EU (Purchase Directly from Amazon.de). As expected there are many other drive models at around the same price tag but not as small and as fast as the Diamond D20 and in the end that's pretty much it's only strong card. The scratch-proof aluminum housing is also something we don't really see much with 2.5" portable hard drives but i would swap if for a rugged enclosure like that of the A80/A15, however that would mean doubling its size and that's not what the Diamond D20 is all about. Bottom line for excellent build quality, blazing fast speeds and its size/weight thanks to which we can actually refer to as portable we award the Diamond D20 500GB USB 3.0 PHD by Silicon Power with our Golden Award.
