Kingston SDCA3 / 32GB MicroSDHC Card / SDXC UHS-I U3 90R / 80W (SDCA3) with SD Adapter (Personal Computers)

Customer Review

Sometimes comments from amazon customers are mixed to various references. In advance, we point out that this test regarding the micro SDXC UHS-I U3 reference, with a capacity of 32GB and comes with Adapatateur SD.

# Protocol test
As benchmark tool I will use AS-SSD, which can measure the flow rates at once in sequential read and write at once, all over the map.

We measured these flows with and without the adapter. With adapter, a PC gaming Asus ROG G750. Without adapter directly on the microSD slot of a tablet Surface Pro 3.

# Results
The results obtained are as follows:
- Without adapter: read seq. -> 83.46 MB / s; Seq in writing. -> 57.68 MB / s;
- With adapter: read seq. -> 85.16 MB / s; Seq in writing. -> 54.78 MB / s.

Several observations. First, the results are substantially identical readings with and without an adapter. Furthermore, the map clearly surpasses the U3 class (about 55 MB / s against 30 MB / s minimum for a class U3). In practice, this means that the card will be quite the case for a camera in burst mode.

In reading, the card behaves perfectly with almost 85 MB / s.

Obviously, we note that the rates indicated by the manufacturer are respected practically in reading, but they are optimistic of writing. However, in practice it does not really result since these performances are simply excellent.

# Regarding the warranty.
The lifetime warranty on the packaging lawfully presented results in France by a 10 year warranty.

Conclusion # #
This microSDXC card has impressive write performance, surpassing without problems UHS-3 standard. It should meet without problems any equipment requiring high flow rates and is ready for 4K video. The warranty provided should reassure you about the longevity of this accessory and the sustainability of stored data.
