### ⭐⭐⭐⭐⭐ Review
*by A***A on June 7, 2023*

I have a Sony a1, 50mp full frame mirrorless camera, which can shoot at 30 fps and to get that speed and hold it, you need very fast storage... so I got this 640Gb card... Yes I could use a cheaper cfexpress type a card or even SD cards, which I do with my Sony a7R5, but for when you want to capture action, and need as fast s burst rate as you can get, you need cfexpress type a cards... I am very happy with how fast I can shoot and while these cards are a tad expensive for me, it was worth having.. I have no doubt, over time, the cost of these things will fall, just as all memory, storage has o er the years... Would I recommend this particular card... Well if you want reliable, fast storage and have the budget, yes... But if you are more of a 1,2 or 3 shot person, then grab a couple of large, compatible SD cards and you will be more than happy... Oh and if video is your thing cfexpress type a cards are really a must... However, it is sad that these cameras can't use the cfexpress type b cards.. but that's another story.
