[ Introduction ]

Today we are checking out a few new portable USB 3.0 hard drives made by Silicon Power, called the Diamond D10 and Stream S20. These 2.5” portable drives come in a range of capacities and we will be taking a look at the 750GB models which are designed to provide plenty of mobile storage without breaking the bank...

After having recently reviewed the Silicon Power Stream S10 750GB portable USB 3.0 hard drive we were keen to check out the newer Stream S20 model. However around the same time Silicon Power also released the Diamond D10 which featured similar specifications, and therefore we thought it prudent to review both products.

Of course you might be thinking these are just more portable devices that feature a 2.5” laptop hard drive and the ability to utilize the USB 3.0 interface. After all, this is essentially what the Stream S10 was so how different can the Stream S20 and Diamond D10 be? Honestly we were thinking the same thing and it seems curiosity got the better of us.

On the surface all three products look very different, though in terms of pricing they are very similar. Whereas the 750GB version of the Stream S10 is still fetching $82 US, the Diamond D10 costs $85 US, and the Stream S20 slightly more at $87 US. It is a very real possibility that all three products make use of the same hardware, as in they use the same hard drive and USB 3.0 bridge chip.

Thankfully this is not the case, at least not entirely, as Silicon Power has shopped around when selecting the 2.5” hard drives. Whereas the Stream S10 employed the Toshiba MK7559GSXP hard drive, the Diamond D10 is fitted with a Western Digital Scorpio Blue hard drive. How much difference users can expect to see in terms of performance is yet to be seen, but this is certainly something we will be looking into.

However, before we check out how each one of these Silicon Power 2.5” USB 3.0 portable drives performs, let’s take a moment to take a closer look at the Stream S20 and Diamond D10.
