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.
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:
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.
