In theory, the Micron C200 is the only competitor to the Sandisk Extreme 1TB; the problem is that there are none available anywhere. Clearly there is a supply issue with Micron and we’re not sure why. Two smaller players (Silicon Power and Integral) have confirmed that they will launch 1TB microSDXC cards in 2020 but unlike Sandisk or Micron, they don’t control the production of the memory chip that goes inside the card. For 64GB-1TB ONLY: A2 performance is 4000 read IOPS, 2000 write IOPS. For 32GB: A1 performance is 1500 read IOPS, 500 write IOPS. Results may vary based on host device, app type and other factors. On the face of it, the SanDisk Extreme Pro seems overpriced. This U3, V30, UHS-I card is significantly more expensive than the Samsung and Integral competition at most capacities, and when tested on our SanDisk ImageMate Pro card reader it wasn’t any faster, at least on sequential read and write speeds, which were 96MB/sec and 85.4MB/sec respectively.

As a result, those hunting for the perfect balance of price and performance don’t need to look any further, and spending just a little more will get you your card bundled with Samsung’s excellent 160MB/sec USB card reader. What more could you want? When I try to copy files to the microcard it will transfer a few gyges but no more. I can see the folders have copied but they are empty. I can copy a few files at a time but this is will too time consuming. Despite being rated faster than the Lexar 1000x, the Lexar Professional 1066x actually uses the slower UHS-I interface. This turns out not to be a big deal, though, as we still measured sequential read speeds of up to 157MB/sec and write speeds of 80MB/sec on our 64GB sample, with the faster 128GB to 512GB versions capable of over 120MB/sec.UHS Speed Class 3 (U3) designates a performance option designed to support real-time video recording with UHS-enabled host devices. Video Speed Class 30 (V30), sustained video capture rate of 30MB/s, designates a performance option designed to support real-time video recording with UHS-enabled host devices.

However, neither standard seems to have taken off yet, either in terms of cards or the readers and devices to support them. Should I always buy the fastest card I can afford?
