Lexar microSDHC UHS-I 633x 16GB Card Review

Final Thoughts on The Lexar 16GB microSDHC 633x UHS-I Card

The Lexar High-Performance 633x  microSD UHS-I memory card lineup is Lexar’s premium series for microSD storage. It doesn’t get any faster than this right now and with speeds hitting 633x or 95MB/s that should suffice for most everyone. Those looking for fast transfer rates and UHS-I and Class 10 speeds ratings can stop looking as this card can handle Full 1080P video recording and even some of the sports camcorders that are now shooting movies at Ultra HD 4K resolutions. Our testing showed that we were hitting 94MB/s sequential read and 25MB/s sequential write speeds. These speeds are close to the quoted rating.

16GB High-Performance microSDHC UHS-I card (633x)

When it comes to pricing the new Lexar high-performance microSD cards start at $34.99 for a 16GB card and going up to $99.99 for a 64GB card. Usually retailers will price items below the MSRP, so we expect to see street prices on these drives to be lower!

Lexar microSD UHS-I Card (633x) Suggested Retail Pricing:

  • 16GB microSDHC – LSDMI16GBSBNA633R – $34.99 USD
  • 32GB microSDHC – LSDMI32GBSBNA633R – $59.99 USD
  • 64GB microSDXC – LSDMI64GBSBNA633R – $99.99 USD

The only thing ‘new’ about these cards other than the color is the 5MB/s speed increase, so right now that means the ‘old’ 600x speed cards that are still widely available might be the best bang for the buck. Lexar will be ending this product line, but for now they are available for significantly less and some might not care about that 5.5% speed increase. For example the 16GB 633x microSDHC card costs 40% more than the street price on the 16GB 600x microSDHC card. This is a horrible comparison though as you really can’t compare street prices versus MSRP, but you should be able to figure out what we are getting at.

Lexar microSD UHS-I Card (600x) Street Pricing:

At the end of the day the Lexar high-performance microSD lineup got a speed boost and no performance junkie can complain about that. If you want to have the latest and greatest Lexar microSDHC or microSDXC memory card in your tablet, smartphone, camera or sports camcorder look no further. 

Legit Bottom Line: The Lexar High-Performance microSDHC 633x 16GB UHS-I memory card was able to handle everything we tried to do on it and the near 95MB/s sequential read performance we saw on USB 3.0 was impressive.

    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.

      • Benjamin Sohr

        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

        • Nathan Kirsch

          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.
