Kingston recently released a new SDHC/SDXC Class 10 memory card line created to be used with smart phones, tablets and still and video cameras. The higher capacity SDXC cards are designed to replace the faster, more expensive UHS-I card – Kingston SDXC 64 GB that technogog reviewed last year.

The target markets for this card line are budget-minded consumers who still desire high quality performance. Kingston designed these Class 10 cards to provide a minimum data transfer rate of 10 MB for optimum performance with SDHC/SDXC enabled devices.

These memory cards comes in either SDHC and SDXC models with capacities from 4GB, 8GB, 16GB, 32GB, 64GB, up to 128G.

Kingston offers both SDHC and SDXC versions in sizes ranging from 4 GB, 8 GB, 16 GB, 32 GB, 64 GB up to 128 GB. For today’s review we will be looking at the 128 GB memory card. With this capacity you should never worry about running out of storage space on your DSLR.

The Kingston SDXC 128 GB arrives on a Kingston branded cardboard with the device found in the within a clear plastic blister card. The back lists the compatibility table for the SDXC memory card. Surprisingly Kingston does not provide a plastic carrying case for this memory card.

Physically the card looks no different than most any other SD card. It is composed of black plastic with a green Kingston label on the front. It is a class 10 card and has a minimum transfer rate of 10 MB/s. On the side is a lock switch which write protects the media. The card is designed to work with most Windows variants including XP SP2 with exFAT update through Windows 7 as well as OS X.


Like any other SDXC card, these Kingston SDXC versions are not compatible with SDHC-enabled devices/readers.

Designed to meet the increasing storage demands of smartphones, tablets and high-quality still and video cameras, these cards use speed class ratings to deliver a minimum data transfer rate of 10MB/s for optimum performance with SDHC/SDXC devices.

To test this Kingston SDXC Class 10 card the the following platform was used along with a Canon T2i:

CPU: Intel Core i7 2600K

Motherboard: Asus P8P67 PRO with USB 3.0

Memory: 8GB Mushkin DDR3 1300

Video Card: Galaxy 460GTX

Hard Drive: Western Digital 250GB 7200RPM, Samsung 1 TB 7200 RPM

PSU: Ultra X-Finity 1000-Watt Power Supply

Kingston Mobile Lite G3 (USB 3.0 card reader)


For benchmarking ATTO Disk Benchmark 2.46, Crystal Disk Mark 3.0.1c and TeraCopy were used. For comparison the Kingston UHS-I SDXC 64 GB with advertised speeds up to 60MB/sec. read and 35MB/sec. write, along with a Super Talent Brand 16 GB SDHC Class 10.

Starting with ATTO using the Kingston USB 3.0 card reader we see the Super Talent with writes around 15 MB/s and reads in the 23 MBs/s range, while our review SDXC is around 14 MB/s for writes and 43 MB/s reads and finally the faster Kingston card has 37 MB/s writes and 63 MB/s for reads.

Next we look at Crystal Disk Mark. While the Super Talent SDHC and the Kingston SDXC 128 GB both had equivalent write speeds of 15.53 MB/s, the Kingston won out on read speeds with 42 MB/s vs 23 MB/s. The faster rated Kingston SDXC 64 GB had read speeds of 58.17 MB/s and write speeds of 38.65.

Using Teracopy to transfer a 1 GB file to and from each card yielded the following results. Once again the latest Kingston SDXC had writes on par with the Super Talent SDHC while it was faster in the read speeds. Again, the older Kingston had the fastest read/write speeds.


For field-testing I shot my daughter’s soccer game using the Kingston SDXC 128 GB and a Canon T2i. Using the highest resolution non-RAW settings the available picture count stayed above 9999 even after shooting hundreds of photos. With the highest resolution plus RAW the total capacity was over 3000 images. This handy chart from Kingston will give an indication of the output for different card sizes.

Shooting video was no problem although my Canon T2i does stop shooting just before the 30 minute mark as opposed to the 12 minute limit with SDHC cards.

According to my Kingston contact this card can also handle high definition video although it is not designed for simultaneous photo and video capture.

The prices of SDXC cards have come down dramatically. In the past a 64 GB card would cost several hundreds of dollars. Now 128 GB card can be found for under a $150 with the latest Kingston offering being one of them. The new Kingston SDXC series is a good choice for both amateur and professional photographers. Plus Kingston offers a lifetime warranty making this SDXC card one to get.

Compared to its predecessor the Kingston SDXC 128 GB provides more storage capacity for less money than the Kingston UHS-I SDXC 64 GB. There is a trade off in speed, but when used in my Canon T2i there was no noticeable difference in performance. For those who want a faster SDXC card then the older red version is still available at Amazon and, although for almost double the price and half the capacity.



+Capacities go up to 64 and 128 GB
+Perfect for modern DSLR devices
+Competitively priced

-Slower than older Kingston SDXC card

    What happened to the Memory….I sure says 128 GB; but in reality you only get 115GB. Still more than the previous 64GB but certainly not with the standard +/-6% its more like +/- 11% and that is N O T acceptable.
