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 seeing Lexar breaking their own records.
This card is also VPG 400-rated. This rating is kind of like 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 really nice reader that also has 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, and it does still look like currently Lexar cards are 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, it would make sense for Sony to now offer some form of RAW video recording in their high-end cameras since it never really made sense to even offer that with the lower-capacity cards.
As sort of a tech nerd, it’s getting pretty exciting seeing where these CFxA cards are going since Sony’s initial adoption of them with the 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.
I could see more camera companies adopting this smaller format in the future based on what we are seeing with performance here.
