HD Video Read/Write Speeds

Blackmagic Design make a number of industry leading video capture cards, including those which can capture HD material at very high data rates and as a result having a disk with a fast write speed is essential. To aid users in configuring their system for optimal captures Blackmagic includes a utility with their hardware which records the real world disk speed and gives the framerate available for that speed.

NOTE: We are using BMD’s new disk test for this review which is not comparable with the old version. The new version works by writing/reading data to/from our drive (up to 5 GB at a time) and displaying a MB/s figure as well as Frames per Second information. This test is particularly useful as SSDs cannot use their compression algorithms, what we are seeing here is true real-time read/write of video content. Cache burst performance is also removed from the equation by writing large amounts of data which exceed the cache volume.

As the results above show drives are often able to read HD content very well but when it comes to write performance, only a few manage to keep top class performance. The Vector is one of those with a nice balance of 511/503MB/s which sees it take second place in this test, while improving on the read speed of the Vertex 4 by over 70MB/s.
