With more than 80 MB / sec. in the fast lane

Who has always respected diligent when buying on the Class 10, which will be increasingly confronted with the term UHS-I in the near future. The acronym stands for Ultra High Speed ​​and the appendage I (Roman one) are there also on the speed class. New this standard is not actually, but only recently come gradually eg digital cameras on the market that can benefit especially from higher write speed -. More on that later. If you start now to ponder whether he can so use a card at all, I can give the all clear: the card is of course the standard SDXC (cards from 64GB) compatible. Camera and Co therefore need not necessarily be UHS-I compliant. In such a case, the card will run just like a regular Class 10 card.

Unlike here on Amazon displayed (now probably corrected) Transcend is for the card on the packaging a read speed of 80MB / sec. and a write speed of 40MB / sec. to. Fortunately, it concerns with the details not manipulated figures from the marketing department, because in my Transcend RDF5 USB 3.0 card reader creates the little cards in ATTO Disk Benchmark is actually 82 MB / sec. read and 40MB / sec. writing (see my customer image). The high expectations of the speed was so ever completely fulfilled fully on this point.

The fleet dwarf memory plays its advantages of high write speed but especially in a digital SLR camera from - provided they dominated the UHS-I standard. In the case results in continuous shooting in very memory-hungry RAW format has the advantage that the data travels significantly faster from the buffer of the camera on the map. I have deliberately chosen such a memory card as my Canon 650D already supports the fast transfer mode - all previous models do not know the standard and there the card runs then as Class 10th

In burst mode, so I come to 8 RAW images in rapid succession while a normal Class 10 on 7 images brings. A picture is worth not to tear it out now, of course, but the buffer is full only once, you can tell the difference then clearly so. In direct comparison, the class requires 10 a few seconds longer until all data have been flushed first. Among then suffers of course, the release rate of subsequent images when the buffer is full. Here the UHS-I representatives is much faster to work and the image sequence is at full buffer noticeably faster. One should not expect miracles but that's why, of course. It is a small advantage, but no revelation ;-)

Already some impressive plays the UHS-I card from their speed advantage in shooting in JPEG format. Here, the card writes the data so quickly that the buffer until no longer runs full during the Class 10 card eventually runs out of breath and the image sequence is slower again.

Of the also very high reading speed then profited by the photo session but again everyone who owns a newer USB 3.0 card reader. If one reads the card, you have over a regular Class 10 card is a good four times higher transfer rate. For large amounts of data, which can occur even with video, you will not appreciate having to wait so long.

Another tip that many apparently do not heed memory cards usually. Like almost every major manufacturer also offers a lifetime warranty Transcend (30 years) to the memory card. To this benefit, the card with the serial number on the Web site of Transcend must be registered. The serial number can be found printed on the card itself small.

CONCLUSION: a very fast memory card at a fair price.
