In CFexpress Cards Go Mainstream in Digital Cameras<\/em><\/a>, I discussed how CFExpress camera cards are becoming the norm in digital cameras. <\/p>\n\n\n\n

\"\"<\/a>
Sony A7R V<\/strong><\/figcaption><\/figure><\/div>\n\n\n\n

The full-frame 60-megapixel Sony A7R V <\/a>has two high speed CFExpress Type A<\/a> slots (one slot can be used for SDXC<\/a> if desired). Sony specifies<\/a> impressively high burst rates as follows:<\/p>\n\n\n\n

No. of recordable frames (approx):
<\/strong>JPEG Extra fine L: over 1000, JPEG Fine L: over 100, JPEG Standard L: over 1000
RAW: 583 frames<\/strong>
RAW & JPEG: 184 frames
RAW (Lossless Compressed): 547 frames<\/strong>
RAW (Lossless Compressed) & JPEG: 159 frames
RAW (Uncompressed): 135 frames<\/strong>
RAW (Uncompressed) & JPEG: 88 frames<\/p>\n\n\n\n

In this article, I set out to test burst speed with three RAW formats using the new 960GB OWC Atlas Pro CFExpress Type A<\/a>.<\/p>\n\n\n\n

Way better than Sony specifications!<\/h2>\n\n\n\n
\"\"<\/a>
OWC Atlas Pro CFExpress Type A<\/strong><\/figcaption><\/figure><\/div>\n\n\n\n

The Sony A7R V is rated for <\/a>10 fps for 583 frames (Hi+, mechanical shutter, Compressed RAW).<\/p>\n\n\n\n

So, how does the 960GB OWC Atlas Pro CFExpress Type A card perform in this beast of a camera? WOW!<\/strong><\/p>\n\n\n\n

The Atlas Pro card hits 835 lossy compressed RAW files at 10.0 fps with no variation right up to the end of the test. Far exceeding the Sony specification <\/strong>and writing a whopping 61.0GB of data.<\/p>\n\n\n\n

At no point was there sign of any stuttering or slowdown<\/em> with the Atlas Pro Type A<\/em>.<\/p>\n\n\n\n

I don\u2019t know how long the captures could have kept going, but not wishing to put excessive wear on the mechanical shutter of my personal camera, I ended the test at ~83.4 seconds (835 frames at 10.0 fps).<\/p>\n\n\n\n

Conclusions<\/h2>\n\n\n\n

The 960GB OWC Atlas Pro CFExpress Type A<\/a> offers fantastic and unprecedented performance, far exceeding Sony specifications for the Sony A7R V<\/a>.<\/p>\n\n\n\n
