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 5GB 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.

In this test the Sandforce architecture offers particularly strong read performance however begins to drop off on writes. Vertex 4 however has much more balanced results which are similar in reads to Marvell, and better than Samsung in write operations.
