Under identical test conditions more quickly than some SDXC card with UHS-I standard

IMPORTANT PRELIMINARY Addition: also mentioned in this test microSDXC card SanDisk has completely given up the ghost after less than 2 months of use (and at this time only about 10 times use). It is sad that the inventor of the SD card now casts such a scrap on the market. I can in any case only strongly advise against the purchase of memory cards of the brand SanDisk. No long-term experience I have with memory cards branded "Lexar" very good long-term experience on the other hand with the brand "Transcend" from me several SDHC cards are not even turned out over the years. So, now to the original test comparison:

This product review can and should help with the issue only "speed means me with SDXC memory cards very much. Does this SDXC card given 10 MByte / s writing speed according to Class 10?", Because more than I can in a few days yet say.

So far I have (see my other product reviews) among the (micro) SDXC memory cards "Lexar Thin Box SDXC 128GB Memory Card (400x Professional UHS-I)" and the "SanDisk Ultra Class 10 microSDHC Ultra 64GB memory card with UHS- I Adapter "- both memory cards of the latest generation with UHS-I specification - tested in terms of their writing speed. Interested readers learn in these two product reviews and what the UHS-I specification is and how it differs from the old "High Speed ​​Bus I / F-classification" - to that described in this product review Transcend memory card belongs - is different.

As well as the aforementioned memory card I have this Transcend Class 10 SDXC memory card to test the write speed also continuously with random data (Pseudo Random Data) filled until it is "full" was. Attached was this memory card to a USB 2.0 card reader, which / s can allow read and SDXC memory card formats which supports the USB 2.0 specification data rates of up to 60MB. Among these for all three (micro) SDXC memory cards absolutely identical conditions I could determine the following write speeds for this Transcend SDXC Memory Card:

15.0 MB / s (this 64 GB memory card with real 59.5 GB of storage was for just under 70 minutes, "filled") ---> a little more closely: The initial writing speed was around 14% below this value, fell but within about 3 minutes on the value 15.0 MB / s and not dropped back below this.

For comparison - like my other two mentioned product reviews on (micro) SDXC memory cards, proceeding (and there a little more closely described):

Said Lexar SDXC memory card reached an identical measuring method a maximum write speed of 17.6 MB / s (but is also, as it is written, a memory card with the new, significantly faster specification "UHS-I", by me but with a Card Reader has been tested, the "UHS-I" is not explicitly supported).

Said SanDisk microSDXC memory card reached an identical measuring method a maximum write speed of 11.5 MB / s (and also, as it is written, a memory card with the new, significantly faster specification "UHS-I" made by me also with a Card Reader has been tested, the "UHS-I" but does not explicitly support).

Conclusion: under absolutely identical conditions during test the write speed of three (micro) SDXC memory cards these Transcend Class 10 SDXC memory card proved in fact a real surprise - it reached 15 MB / s but a significantly higher writing speed than one respect (!) your capacity identical microSDXC memory card from SanDisk, which is actually, because of your latest UHS-I specification, in turn, should be much faster than this Transcend SDXC memory card without UHS-I specification (as the Lexar also is yes).

You may Transcend memory card so confidently use for most HD applications and for continuous shooting in the highest resolution + lowest compression without you ever notice a delay in the storage of the data generated.
