To compare external HDDs with the most popular interface, we've taken seven products from four brands. All of them have the same storage capacity of 750 gigabytes (traditionally for HDDs, these are decimal gigabytes, so the real capacity of each model is somewhat lower than 700 “normal” gigabytes).

Two of the products to be tested come from the well-known makers of HDDs, Seagate and Western Digital. Two more are provided by Transcend and the remaining three, by Silicon Power.

Testing Participants

We will present the products to you in alphabetic order.

Seagate FreeAgent GoFlex STAA750201

 

  • Capacity: 750 GB
  • Interface: USB 3.0
  • Dimensions: 89 x 22 x 132 mm
  • Weight: 286 g

We used this external HDD in our review of USB 3.0 flash drives for the sake of comparison. It's got a typical exterior design for its product class: a flat box with rounded-off edges. The box is black; the activity indicator is white.

The key distinguishing feature of Seagate's GoFlex series is that you can replace the interface by purchasing adapters for FireWire 800 or eSATA.

 

Silicon Power Diamond D10

 

  • Capacity: 750 GB
  • Interface: USB 3.0
  • Dimensions: 75.8 x 13.6 x 124.8 mm
  • Weight: 153 g

This small box with a shimmering blue pattern on its top panel looks cute. The USB connector is located on a longer side panel rather than on a shorter one.

 

The HDD comes with a pouch which is made of artificial leather that feels nice but doesn't smell pleasantly. The lining of the pouch is some soft fabric.

By the way, you can't connect a USB cable to this HDD without taking the latter out of the pouch.

Silicon Power Stream S10

 

  • Capacity: 750 GB
  • Interface: USB 3.0
  • Dimensions: 78.8 x 17.7 x 134.2 mm
  • Weight: 149 g

The shape and color of the junior model in the Stream series do not match each other well. If this design is supposed to convey the speed-inspired style of Italian sports cars, red would be much more adequate than this canary-green.

Otherwise, this model is similar to the Diamond D10. It's got the same packaging and accessories and its USB 3.0 connector is located on a longer side panel, too.

 

There are some differences, though. The pouch is designed as a book cover. It’s a cardboard frame wrapped into a piece of fabric with stitching the color of the HDD itself. The lining of the pouch is the same soft fabric as that of the Diamond D10's pouch. The two halves of the cover are joined with elastic straps that leave a lot of free space at the sides, making it possible to connect a USB cable to the HDD without taking the latter out of the pouch.

Silicon Power Stream S20

 

  • Capacity: 750 GB
  • Interface: USB 3.0
  • Dimensions: 80.1 x 21 x 142.4 mm
  • Weight: 157 g

The Stream S20 is in fact identical to the above-discussed Stream S10 in its exterior design and accessories. The shape and dimensions of the case are somewhat different, but the overall style is unmistakably the same. Silicon Power draws inspiration from sports cars, but the result is still rather poor.

 

The Stream S20 comes with the same accessories as the Stream S10 except that it lacks a software disc.
