microSD Card V60 (128GB) - Tested for Full Size SD Card Devices | Up to 250MB/s Read, 130MB/s Write ProGrade Digital

This is a wonderful little micro SD card. As you may know, reviewers listing speed performance don't always know what they're doing. First, you need the right kind of card reader, and then you need to make sure the USB ports on your computer can handle the higher speeds as well. And then you need to verify what format you're testing... etc.That being said, with all of that in check, I was pulling just over 200 mb/s read and just under 100 mb/s write speeds. Super quick for a micro SD.But everyone about to purchase this card needs to know one crucial detail - this is a UHS-ii card, NOT a UHS-i. This means that the card has two rows of gold contacts on it to help produce this speed. And ProGrade did a great job of sending a UHS-ii sd card adapter that works beautifully - so long as your card reader is also UHS-ii, etc, etc.But, why is this a problem? My Insta360 RS One 1-inch camera and DJI Mavic 3 are only UHS-i. The UHS-ii card will still work in these devices, but will only use the main row of gold contacts to read and write data.What this means is that the UHS-ii card will only work as a UHS-i card in these devices. To test this, I used the micro SD (UHS-ii) in a UHS-i SD adapter for the test. In this case, the speeds were cut quite significantly - consistently 90 mb/s read but between 60-80 mb/s write. And my SanDisk Extreme Plus consistently pulls over 90/80.So, if you're just needing transfer speeds to get the data from the card to your computer, or if your primary device writing data to this card is UHS-ii - this is a great card. But if you're needing the read and write speeds on any kind of device that only uses UHS-i, you'll be better off getting a SanDisk Extreme Pro micro SD. But for most of us, this is a case of great design that most technology hasn't quite caught up to utilizing just yet.Hope this helps!

Super fast transfers. My drone loves it!

I use almost only prograde SD cards. they have worked great and been good quality. No need to switch things up now. great product.

This SD hadn't failed me yet when shooting projects and relying on the 4k 60f footage to be there at the end of the day. Transfer speeds and storage is perfectly ideal for what I need for my Drone business.

This item is rare in the UK, i had to import it to enjoy the free software attached to the product which has very good read and write speeds, the ProGrade Digital brand is one i personally like and there other products are worth viewing and considering , i am very happy with my purchase and will purchase again soon.

I use it with my Insta 360 Ace Pro 2, and works fine.

Those works well for a 4k drone, however I am questions the write speed due to delay time in between taking photos. The pause between taking photo's is annoying. When it was new there was no issue, 30-60 days later the slowdown and delayed started to be noticed.I will be trying a V90 next, as soon as the price on them become more realistic.

The MicroSD card is made in Taiwan. The SD Card adapter is made in China (that's why I subtracted 1 star). Hopefully one day the adapter is no longer made in China. Other than that it works well. I use it for my GoPro Hero 10.
