Kingston 64GB microSDXC class 10 with Adapter

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


  • None

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.

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.

    If your PC isn’t seeing the card using a card reader, I don’t of another way to recover files from it.

    @Ed Rhee

    Sounds great, Ed! I switched back to using my old 32GB card because of all the hassle with my Kingston 64GB card. Would gladly give it another go if I got an updated version.

    Hey everyone,

    Thanks so much for all your feedback on the problems you experienced with the Kingston 64GB microSDXC card. I was able to work with Kingston to confirm that there was a problem with a batch of these cards. I’m told that this batch is no longer being shipped and that the new batch does not have these issues. Here is their official support FAQ advisory on the issue:

    *ADVISORY* My microSD card worked in my Android 4.1 or 4.2 device but after a short time, it is no longer accessible and has locked up. How do I resolve this issue?

    A problem has been identified with some microSD cards and Android 4.1 & 4.2 based devices like the Samsung Galaxy S3, Samsung Galaxy S4, and Samsung Galaxy Note II that causes the card to become unresponsive after being used for a short time. Kingston Technology has taken the necessary measures to resolve the issue but it is always a good idea to keep a BACKUP of ALL important data. If you are experiencing this problem, please contact our Technical Support department for a resolution.

    Essentially, if you are having problems with your card, you should contact Kingston Tech Support to get the card replaced. In addition, for those of you who have left comments here, I will be getting in touch with you privately to offer you a brand new card from Kingston to thank you for helping them identify the issue.

    Same problem for me with the Kingston 64gb sdxc and my Note 2… Shows up fine at first but after a couple of minutes it starts showing errors and lag the system…

    Sounds very familiar. I had the same experience, and when I exchanged it for a 64GB Sandisk, there were no more issues.

    I had the same problem with a new kingston 64gb microsd xc card on my new galaxy note 2, which i purchased a month ago. I read this blog and formatted the card in phone….the problem was gone for a month but now it again recurs. The system becomes very unstable when browsing contents of the sd card, which momentarily fails to display the media thumbnails…hence fails to open the files missing the thumbnails….This also made the phone restart automatically…may be it froze while opening the unreadable media…but after turning off the phone, reinserting the card and turning on the phone, the problem was gone…. Thankfully none of the files in the card was corrupted and the phone could read the files (photos , videos and songs) normally. I m planning to buy a samsung branded 64gb micro sd xc card…which may perform better in note 2, or else it would be a nightmare to see all contents of my card unreadable on one fine day….

    Im having the same problem now with my Galaxy S4 after a day of putting in the Kingston 64GB microSD. The first time I restarted the phone and it was resolved. Then some 8 hours later it reoccurred with the same error “damaged sd card” asking me to reformat or cancel. I restart the phone a few times – did not resolve the problem. I then removed the SD and reinserted it – is working fine now, until it fails again. The first thing I did when I got the card a day ago was format using the phone, so it should have the correct file system.

    I’m fairly sure now that the problem was in the formatting. I haven’t had any more issues since I formatted the card in the device.

    I have this problem as well, it was formatted as exFat, after a few days the problem appears. I formatted the card as fat32, going well for a few days and now it appears again. Not sure whether the problem with Galaxy Note 2 or with the SD Card.

    @Ed Rhee
    The video files were the worst, but I had trouble with MP3 files as well. It’s now over 24 hours later, and no problems. I think the problem may have been solved by formatting the card with the phone itself.

    Hmm, that’s weird. I actually have the 64GB card in a Galaxy Note 2 as well, and haven’t had any problems with it. I’ve got about 10GB of music on it and the camera saves photos to it constantly. What kind of media did you have a problem with?

    I put a Kingston 64GB card in my Galaxy Note 2, and it worked fine for a few days. Then it started giving me errors when I tried to play media files from the card. It would say “can not play this media type” one minute, and then play it the next. Once it said the card was damaged and should be reformatted. I returned and exchanged the card, but the same problems appeared. I reformatted the card in the phone, and 12 hours later, so far, so good.
