This latest version of the top-of-the-line Extreme Pro line is labeled both with V30 for 4K video recording and A2 rating for app speed. It’s rated for 90 MB/s sequential write speed and 170 MB/s sequential read. SanDisk comes out with new models quite frequently, and there’s not always a lot of performance improvement between them (which is why there are so many near the top of the table below). This latest version claims a boosted read speed over the previous model, but the reality is that the past few iterations of the Extreme Pro have had much the same write speed, so if you can’t find this latest version, you can be confident getting a recent previous version.

100% Authentic / Genuine
Fulfilled by Amazon Seller King-Disk Product: Sandisk Extreme Pro 128GB A2 Device used: S10 plus Upon receiving this microSD last night, I immediately put it on a test for authenticity verification and yes this is 100% authentic since it meets the "guaranteed" write speed of V30 classes. However, there are not so good things that I have discovered: The real life speed is far from its advertised speed: **up to 170mb/s read speed and 90mb/s write speed Benchmark results (using various pc and android apps) Sequential Read: 80mb/s average Sequential write: 50mb/s average Random Read: 7mb/s average / 1,900IOPS Random Write: 3mb/s average / 680IOPS These results definitely doesnt meet the A2 requirements in read speed (4,000 IOPS) and write (2,000 IOPS). The results are closer to A1 rating. If you are considering picking up an A2-rated microSD for your apps, this is not worth it but if you are just going to save your data, you can go for it as there will be no issues in playing content from this disc. Note: you may still be able to reach the advertised read and write speed if you will be using the SanDisk card reader and plug it into your computer.
