Lexar 16GB MicroSD 633x Smartphone Performance

We also wanted to check out the speed on a mobile device, so we fired up the SD Tools v 3.5 App on our Samsung Galaxy S4 Smartphone that is running Android 4.3 to see what the Lexar 16GB microSDHC 633x card is made of.

lexar-sdtools

As you can see from the screenshot above the App was showing that we were getting 19.6 MB/s read speeds and 13.7MB/s write speeds.

sd-benchmark

We also ran the A1 SD Bench v2.0.0 App and after running the long benchmark it was showing that we were getting 18.36MB/s read speeds and 15.28MB/s write speeds. Notice that there is a total of 15,263MB of space on this Flash drive.

    Sony memory card is quite exceptional as it classified in the class 4 category which is quite good. Its 16 GB space capacity gives you the full independency to store enormous amount of data. It is compatible with all other devices.

    Sorry, but your testresults are absolutly false! I dont know what you`ve done, but my card is twice that fast than yours.

    • Nathan Kirsch

      You do know there is a write performance difference between the 16GB card and the 32GB card that you have correct? My result isn’t false, you are just seeing different results due to the density on your higher capacity card and how many lanes are available to the NAND to connect to the controller.

        Okay, I dont expected a difference like that. What I want to say is, that the lexar is one of the fastest cards on the market at the moment 04/2014 and it works absolutly great in my gopro in contrast to a sandisk card. Greetings Benny

          Benjamin, I asked Lexar for the official speed numbers and I have attached it. The 16GB card is 95MB/s read and 25MB/s write. The 32GB/64GB cards are 95MB/s read and 47MB/s write. The reason is due to what I mentioned above. Your card write speeds are spot on as are mine! Hope you better understand what is going on.

    Why recommend horribly bad memory cards? The Sandisk Extreme Pro costs less ($90 for 64gb) and has nearly double the write speed (which matters more than read for memory cards). Hell, even Samsung has a 60-30 card for $60 that could be considered better value!

    • Nathan Kirsch

      I took a quick look at the Sandisk Extreme Pro microSDHC 16GB card (SDSDQXP-016G) and saw it cost more $39.99 and had the same 95MB/s rating. Now digging into the specifications it looks like the write is indeed at 90MB/s as well. That does indeed change things. Thanks for bringing that to my attention.

        Oops, it’s “Extreme Plus” for 64gb version, with 80/50 rating (though predicessor had 95/60 tested even with the same rating). 4k writes are also double at ~2mb/s, so it should be able to easily best the Lexar (and includes rescue pro, which is a photographer’s best friend, especially when cops are involved)

          Note Gopros black 3+ don’t like Sandisk cards and reject them regardless of their write speed – many articles on www about it

          My Gopro h3+ black loves my sandisk extreme 64gb in all modes, including protune. Earlier issues were with the Ultra cards.
