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.

Of the Sandforce drives it is interesting to note that the XLR8 is managing to get some extra performance out of writes on this test, exceeding 300MB/s which is the fastest we have seen on Sandforce up to this point. Reads are reasonably competitive too but Samsung, Indilinx and Marvell controllers do particularly well in this test.
