Testing Thunderbolt-Enabled External Storage: Gigabyte Z77X-UP5TH meets WD Velociraptor Duo
Benchmarks: PCMark 7
PCmark 7's 'Importing Pictures' test provided some interesting results as the 520 Series drive was clearly faster when using SATA 6Gb/s, providing 3MB/s more bandwidth. However, the Velociraptor drives benefited the most when using SATA 6Gb/s, jumping from 7.8MB/s on Thunderbolt to 17.6MB/s.
The video editing test again showed that the Velociraptor drives were much faster on SATA than Thunderbolt. This time, the 520 Series drive only showed a mild improvement but SATA was still faster.
We recorded a huge difference in performance when comparing Thunderbolt to SATA: the Velociraptor drives were almost 4x faster when connected to the latter interface.
The last PCmark 7 storage benchmark we're going to look at is the gaming test, in which the Velociraptor drives were over 1.5x faster when using SATA 6Gb/s versus Thunderbolt.
