I tested the performance both in-camera and on my PC (make sure you have a UHS-II capable reader). Easy to measure the performance on my PC, and I was very pleased to see both read and write speeds very close to the listed speeds. No way to directly measure I/O performance in the camera, but buffer flush operations were very quick.
Install the SD card monitoring software. Flash memory cells do wear out, and getting an early warning that your card is wearing out is pretty important.

Fast cards have two advantages:
Rapid burst shooting: if you shoot tons of photos in a row, the buffer of your camera will fill, and then the speed of the card will matter. If you take photos in short bursts, or just one at a time, there isn’t much of a performance point in getting a fast card.
Image offloading: if you have a fast card reader (UHS-II), you can offload photos from your camera to your computer much faster if your card is also much faster. This benefits all people, regardless of the camera they own. It’s especially useful if you shoot a lot on the run and need to quickly offload photos to a laptop.
This card is fast, the buffer clears faster than my previous card rated at 150MB/s, but not *that* much faster. I tested it in two different card readers and I couldn’t get the speeds Sony advertises on the cards. I got around 200MB/s write and 235MB/s read. Really fast, but not the 299/300 printed on the card. For that, they lose some stars.
When it comes to memory, use a trusted brand and don’t screw around with the risk of having a cheap card potentially get corrupted or die on you. Also keep in mind that even the best memory cards have a lifespan so if reliability is important to you, it’s generally a good idea to periodically buy new cards anyway while you rotate older cards out and away from mission-critical use.
It can’t be accessed by the camera, PC, or any other device for that matter. It simply doesn’t show up, like nothing is inserted. I cannot check it for errors or even format it.
It simply died, just like that. I returned the card to Amazon, and I’ll be looking for an alternative.
Unless it fails on me prematurely, it is what it is. It handles long bursts of 10fps of uncompressed 24MP RAW . Solid product and comes in at a lower price than my usual Sandisk Extreme Pro cards. I feel fine recommending them and will purchase more for backup, capacity upgrades, and replacements.
