Read performance is great -- using the included USB reader I was able to get 140MB/s read. Write speed on the other hand is disappointing, again using the included USB card reader, I was only getting 40MB/s.

Update: retested this on a PC running Windows 10. Previous test was done on an iMac and I mistakenly made the assumption that the test result on iMac would be comparable to test results posted by others using CrystalDiskMark. A sequential write speed of around 60MB/s was obtained on a PC, making it a significant improvement of write speed over the blue colored 633x card. I am updating the score to 5 stars.

Realizing that the benchmark results posted by other folks are not necessarily directly comparable to mine I set out to create a comprehensive list of current microSD cards on the market. The results are below.
---------------------------------------------------------------------------------------------
I had the opportunity to compare the performance of the fastest microsd cards currently available from top manufacturers. All cards mentioned in this review are obtained from Amazon during the last week or two except when noted otherwise.

Test Setup:
Lexar Professional workflow UR1 microsd card reader was used for all tests except when noted
CrystalDiskMark 5.0.

Warning, you need a device that supports the physical UHS-II interface to get the full speed on this product. Most microSDXC slots are NOT UHS-II, many even relatively new devices are only UHS-1. I made the mistake of trying to use this with the 2016 version of the Intel Compute Stick and that device only supports UHS-1. The net result is that the write transfer times are significantly slower with the Lexar Pro 1000X device than they are with the more commonly available and often cheaper UHS-1 cards.

However, the USB3 adapter that comes with the Lexar Pro 1000X does provide pretty speedy performance, with reads around 150MB/s and writes between 70 and 80MB/s (measured with the CrystalDiskMark v5.1.2 utility). Contrast that to the what I got in the Compute Stick's UHS-I port, about 70 to 80MB/s on reads and only 25 to 50MB/s on writes (roughly one half of the speed that was produced with the USB3 adapter).

In any case, note that the speeds shown above are with a benchmarking utility, so in either case your day-to-day transfer times are likely to be even slower than what is indicated above.

Lesson learned, not all microSDXC UHS ports are the same when it comes to read/write speeds. Basically, if your device only supports UHS-I then you want to buy a UHS-I U3/Class10 device for the best possible performance (as of spring 2016).

I purchased two of these from Amazon. Both failed within 20 minutes of use. The first one failed when trying to copy large amounts of data to it all at once (somewhere around 30GB it went kaput). The second one failed when trying to reformat as NTFS. Both are completely dead. I tried various readers with USB 2.0 and 3.0 ports to no avail. I wonder if these are counterfeits as I have had no problems with the 32GB so far with extensive use. Likewise, I have had no problems with the 128GB 633x ones either.

I have installed this Micro SD card into my Samsung Galaxy S5. I also have a TP-Link Archer C7 dual-band router at home. I have a USB drive in the back of my router that acts as my own little personal cloud storage. I use it to back up videos and movies from my cell phone when it gets full. With my previous micro-SD card it took 5-10 minutes to back up about 250 photographs and a few videos on my 5Ghz band. Now, the same amount of stuff takes about 45 seconds to move. I'm thrilled at the transfer rates I'm getting!

Runs absolutely perfectly in my Moto X Pure Edition phone, used as adoptable storage. When converting to adoptable storage I still got the warning that the card appeared to be too slow and may cause performance issues. Well, rest assured it does not. Not sure what would not get that warning as this is one of the fasted cards you can buy right now, especially at this price point. Kind of wish I had gotten the 64 GB version though for the extra space, and according to another reviewer it slightly faster too. But this is plenty fast as it is.

With the included reader I wasn't quite hitting 45MB/s (about 5x faster than my 128GB SanDisk Ultra) of writes from a fast SSD on a USB 3.0 port. Sadly, after only a few GB of writing the copy starting generating errors. After 16GB the card failed completely and cannot be formatted.

The included adapter gets very hot with use. This may have caused the failure.
