This test compares SDXC cards with 64 GB and microSDHC / XC cards for cameras in price, time and capacity. Meanwhile some card manufacturers offer SDXC cards with 256 GB. However, prices are demanded, for which one can already acquire a complete camera. In everyday life you rarely need so much storage capacity. The market for such storage giants should therefore be very small. The entry level for the SDXC cards is 64 GB, and for most photographers this is more than adequate. They are suitable for multi-day trips, when no backup device can be taken and you do not want to deal with many cards.

28 SDHC memory cards in test
Time measurements
Eng could it be only if one is synonymous like filming - the memory requirement for video recordings is unequally larger. Since every laptop now has an SD interface, SDXC cards can also be used as a USB stick replacement. The second test group is characterized by particularly small dimensions: microSDXC / HC cards have been developed for use in mobile devices, above all the smartphones. But with an adapter they can be operated without problems also in cameras. The small micros get up to 64 GB, and they do not have to hide behind the bigger siblings even at speed.
Test results
In the first task, we determined how many images (RAW + JPEG) can be recorded in sequence without the camera stopping. On the Sony A99 alone, there were significant differences. For the remaining cameras, the difference was in the best case 2 images. On the A99, the slower maps - with approximately 30 MB / s writing speed and below - managed about 14 to 16 shots. The two equally fast SanDisk Extreme Pro models were placed at the front with a clear distance from the main field: the 64 GB SDXC with 41 and the 16 GB microSDHC with 49 images. The closest followers, Lexar 600 and Panasonic Gold Pro, managed 23 consecutive pictures.
Conclusion
At the end of the measurements, all five cameras showed a similar ranking without great differences. The slowest cards in the test were those with a writing speed of up to 30 MB / s. They took an average of 3 times as much time to store 20 RAW + JPEG shots as the fast models. The distance is clear, but not as large as the SDHC measurements of the last two editions, in which we measured factor 7 to 8. Outliers in this group were Toshiba microSDHC and the PNY SDXC - both cards showed significantly better results than comparable fast-paced models.
The Panasonic Gold Pro SDXC also had a positive impact - it surpassed approximately the same speed Sony and Samsung SDXCs and was at the Lexar 400 with 60 MB / s writing speed on both Canon cameras and on the A99

As far as Lexar is concerned, the differences between the 400 and 600 versions were generally small. The much higher acquisition price of the 600s is thus hardly justified, even if this was always at the front. The tip was the two SanDisk Extreme Pro cards, the small microSDHC surpassing the larger SDXC on almost every camera: only on the Nikon D5200 (test) both were the same with the Lexar 600er. Obviously, the smaller storage volume and thus the lower administrative burden will add an extra tadpump in speed.
The reviewers are clear this time, it's the two SanDisk Extreme Pro cards: expensive, but fast. And it is also clear that the smaller microSDHC / XC cards can be just as fast as the larger siblings. In practice, however, one should pay more attention when dealing with them - the tiny ones are quickly lost. The price / performance tip comes from the PNY Professional X SDXC, the Samsung Class 10 SDXC and the Toshiba Exceria microSDHC - all around 1 Euro per GB and with good times.
