The Kingston 32GB UHS-I U3 Flash Card we are testing today is available online at the retail price of $52 (amazon.com).

The U3 SD card has a brushed nickel decal, distinguishing it from the others in the Kingston brand.  Kingston has also printed the brand, write speed, read speed and capacity on the face of the card, also included is the slide lock which will enable the prevention of data loss.

And of course, the UHS Speed Class 3 (U3) symbol on the card indicate its minimum writing performance:

It's time to run some benchmarks with the new SD card. For our tests, we measured transfer speeds from the 32GB Kingston SDHC/SDXC UHS-I U3 card using an Kingston MobileLite G3 memory card reader plugged into a USB3.0 slot of a PC.

The first sequential transfer tests come with the H2Testw software. Sequential read speeds measured 78.8MB/sec reading while write activity hit 56.9 MB/sec.

The read spec was almost in line with what Kingston quoted, although the write speed came up a little short. But compared with other Class 10 cards we have tested so far, the Kingston SDHC 32GB UHS-I U3 deliver the fastest reading/writing speeds.

The CrystalDiskMark 3.0.2e x64 edition gave even higher performance figures. The reading speed jumped up to 95.46MB/sec while writing hit the 83.65MB/sec. The 4K/QD32 performance was also improved improved compared with the Kingston UHS-1 SDHC card as well:

The Kingston SDHC 32GB UHS-I U3 seems to deliver top- notch performance and makes the difference especially at the writing part.
