Kingston 64GB Class 10 microSDXC flash memory card
Kingston recently announced the availability of their 64GB Class 10 microSDXC memory card. After reading the press release, it got me thinking: how many memory manufacturers make a 64GB Class 10 microSD card? A quick search on Newegg turned up just one. With Kingston’s hat in the ring, now there’s two. 64GB is enormous for small devices, like smartphones and tablets. The storage advantages are pretty obvious, but I took a look at the Kingston 64GB microSDXC card for performance as well. The results were pretty impressive.
- Great performance
- Huge capacity
- Lifetime warranty
- Includes SD adapter
When I first started using smartphones, I didn’t particularly care how much storage they came with. I removed apps I didn’t use and transferred photos and videos to my PC on a regular basis. I also didn’t use my smartphone as a music player; I had my dedicated MP3 players for that. Then, smartphones started coming with very high resolution cameras and 1080p video recording capabilities. Apps were also getting more complex and taking up more space. Out of necessity, I became more storage-conscious. Once I decided to use my smartphone as my primary music player, it was all over. I needed big-time storage — something like the Kingston 64GB Class 10 microSDXC card.
DESIGN & FEATURES
There are two SKUs for the Kingston 64GB Class 10 microSDXC card: one with the SD card adapter and one without. My test unit came with the SD card adapter.
I tested the Kingston card in a USB 3.0 port on a Windows 7 PC, using a USB 3.0 card reader with native microSDXC support. The sequential transfer rates from CrystalDiskMark were 42 MB/s read and 15 MB/s write. The write speed easily exceeded the 10MB/s minimum for its Class 10 rating. In real world testing, transferring media from my PC to the card was fast and I had no problems while taking photos and capturing 1080p video on a Samsung Galaxy S III Android smartphone.
When choosing an SD card, most people only consider the capacity and performance (class rating) of the card. That’s because most devices and computers support most available SD cards. It’s important to note, however, that SDXC is the newest format, surpassing SDHC. SDHC maxes out at 32GB capacities, while SDXC cards can reach capacities of up to 2TB. If you want to use SDXC or microSDXC, your device has to support it. Newer devices, like the Samsung Galaxy S III, have microSDXC support, but you’ll want to check your device manufacturer’s specifications to make sure. The last thing you want to do is get your brand new SDXC card, then find out that your device has no idea what to do with it.
Additionally, if you plan to use the cards in a computer, your OS has to support the exFAT file system used in SDXC cards. For Windows, anything above XP SP1 (with exFAT update) should be fine. For Macs, OS X Snow Leopard (10.6.5) with the exFAT file system update is the minimum. Don’t forget that your memory card readers will also need to support SDXC/microSDXC as well.
The Kingston 64GB Class 10 microSDXC flash memory card may seem like a luxury at first, but if you use your devices to their full potential, you’ll soon realize that the extra storage is almost a necessity. The Kingston card offers a huge amount of storage, without sacrificing any performance. To top it off, Kingston includes a lifetime warranty. If you’ve got a device that supports SDXC/microSDXC, you can’t go wrong with the Kingston 64GB Class 10 card.
