Review of Kingston 64GB microSDXC Class 10 Flash Card

Up for review today I’ve got another microSD card, well actually it’s technically a microSDXC card. The card is the newest 64gb from Kingston which is a class 10 card offering minimum speeds of 10 mb/s, which should be fine for any HD recording that you might need or want to do. I’ve put it up for comparison against several other microSD cards I’ve got on hand and this new card from Kingston performs well overall. It’s not the fastest of the bunch, but it sure is the biggest, so if you need storage space, then Kingston has got you covered.

So it’s a microSDXC or microSD card basically. Not much to really look at in terms of product shots for sure. There is a difference of course between microSDHC and microSDXC, but really the only thing to worry about would be is your device compatible with sdxc cards or not?!

The package is cardboard with plastic and you can see the microSD card itself and the adapter on the front.

Inside you’ll only find the card and adapter.

Then here’s the card itself:

Yep, it looks like  microSD card to me!

microSDHC/SDXC Card — Class 10

As someone who jumped on the latest, highly advanced phone, tablet or camera, you’re probably not a big fan of waiting around. And who can blame you — life is short and you’ve got better things to do than wait around for your pictures, movies or music to transfer to your PC. That’s why Kingston® offers the Class 10 microSDHC/SDXC card, featuring the fastest speeds available in a microSDHC/SDXC card.

Since I recently reviewed the ADATA 16gb card, I figured why not just expand on those test results.

I only have one other Class 10 microSD card so I did a couple more tests on it and the Kingston for a little more in-depth comparison.

So here are the cards used for comparison:

32gb Kingston Class4

1gb Kingston microSD

16gb Kingston Class2

8gb Kingston Class4

4gb Sandisk Class4

2gb Kingston microSD

4gb Transcend Class6

16gb ADATA Class10

and of course the Kingston 64gb Class 10 as well.

First is the actual results using ATTO:

 

1gb kingston 2gb kingston sd 4g sandisk class4 4gb transcend class6 8gb kingston class4 16gb adata class10 16gb kingston class2 32gb kingston class4 atto 64gb kingston sdxc 

Then here’s a handy graph showing you the results in kb/s for both read and write. I ordered the chart using the Read scores for reference, slowest to fastest.

Specs for the Kingston card say you should get a minimum of 10 mb/s speeds and I think we more than hit that. The card almost doubled that at a little over 19 mb/s for Read Speeds. For Write speeds it goes just over 11 mb/s, which is still more than the specs state.

10MB/s is the minimum write speed needed for HD recording so the results from the Kingston show HD recording should work perfectly fine with this card.

Then again, personally, I wouldn’t be using this card for HD recording really, it will most likely be in a tablet used for storage and reading from really. It all depends on your needs really I guess, but it will work for HD recording and I guess that’s what counts.

On the two class 10 cards I have I also ran CrystalDiskMark.

Here’s the Kingston results, showing basically the same thing as Atto:

Then here’s the ADATA 16gb Class 10 results, again pretty much the same as ATTO. The Kingston card appears to do better at writes at 4K and 4K queue depth 32.

Yes I know the interfaces look different, apparently you can use  themes with CrystalDiskmark now so I had to check it out, but it’s the same test no matter what it looks like.

 

I also ran the SiSoft Sandra Removable Storage test, which gives us results in IOPS.  No pretty chart for you, just some raw data.

Here’s the overall Kingston results:

Device Score : 150IOPS (10IOPS – 189IOPS)
Endurance Factor : 5.90
Results Interpretation : Higher Scores mean Better Performance.

Then here’s the ADATA overall results:

Device Score : 150IOPS (10IOPS – 252IOPS)
Endurance Factor : 3.90
Results Interpretation : Higher Scores mean Better Performance.

They look pretty much the same to me overall really.

 

The SiSoft Sandra test runs several individual tests for 4kB, 64kB, 1MB, 16MB and 256MB, the above is basically the average of all of them.

I grabbed the 256MB files test results for you:

Kingston:

256MB Files Test
Read Performance : 0.07IOPS (0.07IOPS – 0.07IOPS) / 18.45MB/s (18.45MB/s – 18.45MB/s)
Write Performance : 0.04IOPS (0.04IOPS – 0.04IOPS) / 9.43MB/s (9.43MB/s – 9.43MB/s)
Create Performance : 237IOPS (237IOPS – 238IOPS)
Delete Performance : 82IOPS (82IOPS – 82IOPS)
File Fragments : 1.0
Aggregated Score : 0.06IOPS (0.06IOPS – 0.06IOPS) / 15.29MB/s (15.29MB/s – 15.29MB/s)

 

ADATA:

256MB Files Test
Read Performance : 0.07IOPS (0.07IOPS – 0.07IOPS) / 18.86MB/s (18.86MB/s – 18.86MB/s)
Write Performance : 0.06IOPS (0.06IOPS – 0.06IOPS) / 15.6MB/s (15.6MB/s – 15.6MB/s)
Create Performance : 384IOPS (384IOPS – 386IOPS)
Delete Performance : 14IOPS (14IOPS – 14IOPS)
File Fragments : 1.0
Aggregated Score : 0.07IOPS (0.07IOPS – 0.07IOPS) / 17.72MB/s (17.72MB/s – 17.72MB/s)

 

Fairly close, with the ADATA coming out faster in the Write tests as we already know from the previous tests.

Conclusion:
The new Kingston 64gb microSDXC class 10 card performs admirably well overall. It performs above specs which is of course a very good thing.

The card easily hits over 19 mb/s for Read speeds and a little over 11 mb/s for Write speeds, which is more than enough to handle any HD recording your might be doing.

If you need more space, 64GB is the largest capacity available right now and you might as well get it from a reputable company like Kingston.

9

Pros:
+Performs well above specs
+Decent overall performance
+Large capacity

Cons:
-Not the fastest in terms of write speeds

    how does it compare with sandisk class 10?

    Spotting a fake Kingston 64GB Mircro SDXC Mircro card.

    The easiest way is check and see if the Serial Number is PYK20130788MB.

    If the serial number does not match then compare the SD Card, Adapter and Packaging to the pictures attached or the pictures in the Review.
