Lexar has sent me this card, and the benchmarks look great.
Lexar 320GB Benchmarks
The new Lexar 320GB card is actually running a little faster than the 160GB Lexar card, which was already the fastest CFxA card, so it’s good to see Lexar breaking its own records.
This card is also VPG 400-rated. This rating is similar to the v90 or v60 ratings with our UHS-II cards, except this new rating guarantees a 400MB/s write speed. This new car also comes with a minimum sustained speed of 700MB/s.
The Lexar CFxA 320GB card can be bundled with the Lexar CFxA reader, a nice reader with the new interface for the UHS-II cards. Remember, for a long time, Sandisk had those 170MB/s cards, but nobody could get those speeds? This new reader allows you to get those speeds. I’ve also seen improved speeds on many of the microSD cards.
Write Speed: 837MB/s
Read Speed: 885MB/s
Here is the full tracker of available cards and what I’ve been able to benchmark. There are now some higher-capacity cards from some of the other brands, but I don’t have access to them yet. It does still look like Lexar cards are currently rated as the fastest.
Video Record Times With Sony Codecs
| Bitrates | 80GB | 120GB | 160GB | 360GB |
| 200Mbps | 53min | 80min | 107min | 214min |
| 280Mbps | 38min | 57min | 76min | 152min |
| 400Mbps | 27min | 40min | 53min | 106min |
| 600Mbps (4k h.264) | 18min | 27min | 36min | 72min |
With this new 360GB card, Sony should now offer some form of RAW video recording in their high-end cameras since it never really made sense to offer that with the lower-capacity cards.
As a tech nerd, I’m getting pretty excited to see where these CFxA cards are going since Sony’s initial adoption of them with limited capacities was a little confusing. It put Sony behind all the other brands with speed and functionality, and these new higher-capacity cards are leveling the playing field for Sony.
Based on the performance we are seeing here, I could see more camera companies adopting this smaller format in the future.
