Performance and price are not proportional when it comes to selecting a microSD card. Some of the worst performing cards in this review also happen to be the most expensive.
Not all 633x cards are created equal. The two cards reviewed from Lexar and Transcend are both marked as 633x but vary in performance greatly.
4k video recording using action cams and drone cameras have a typical bitrate of 60mbps or 100mbps, corresponding to 7.5MB/s to 12.5MB/s. All cards in this review should theoretically be able to handle this usage easily.
Using microsd card as supplemental phone storage potentially could benefit from a faster card,
Best Looking Card (if it matters):
Sandisk Extreme Pro: Red/Gold with white print
Lexar 1000x: White/Gold with Black/White print
Samsung Pro+: White/Black with a red stripe and Black/White print
PNY Turbo: Lime Green/Black with Black/White print
Update 9/14/2015: Added additional cards to the list.
Using a macbook pro w/ the included usb 3.0 adapter my results were:
write max: 38.02 MB/s
write avg: 37.86 MB/s
read: 64.02 MB/s
data capacity: 29.81 GB
write max: 39.15 MB/s
write avg: 38.00 MB/s
read: 63.95 MB/s
data capacity: 29.81 GB
Conclusion... good value, solid performance, reliability remains to be seen. Will update if any issues arise.
PERFORMANCE: This 633X card is rated at 95MB/sec read speed, class 10. And it pretty much delivers on that promise, Using CrystalDiskMark 3 and the supplied USB3 adapter I measured 85 MB/sec. Lexar does admit that "write speeds will be lower", and indeed they were at 41 MB/sec. For comparison a Sandisk Ultra class 10 card I have SanDisk Ultra 16 GB MicroSDHC Class 10 UHS-1 Memory Card with Adapter (SDSDQU-016G-AFFP-A) tested 44MB read and 11MB write in that same USB3 adapter. The Lexar was about twice as fast as Sandisk Ultra. Note that both cards drop dramatically in speed when used in a USB2 adapter. When used in a USB2 reader they were both very similar at 10MB/sec write and 17MB/sec read speeds. So it may be device that you will be using it in that will be the limiting factor rather than the brand of card. Certainly once you record a huge video file on this card, I would use the supplied USB3 adapter to transfer it to the computer, as you may save over three minutes in download time alone.
COMPATIBILITY: I used the card in a GoPro 3+ Silver at 1080p 60 fps without any glitches or problems. No errors, no freeze ups. Since I also had a SD card adapter I inserted the Lexar into it, and the whole setup went inside a Fuji XP camera. (see photo) I was not sure it would work, but it did just fine. So with this one micro SDHC card, you can use it in phones, video devices and older cameras that use full size SD cards as well.
BONUS: The supplied micro SD USB3 reader works perfectly with other micro cards such as the Sandisk Ultra class 10 card, more than doubling its read to computer speed, and also with an older Kingston class 4 micro SDHC card, also increasing its read to computer speed by 50%.
The only con would possibly be the price premium, but the performance is so much higher than the similarly priced Samsung EVOs (They're only 45MB/S max, twice as slow!).
In summary, the benchmark I provided should be enough to make you buy one, or two. :)
accurate. I would not trust any others, including Samsung!! Their speed, performance and longevity are uncanny. Try them and you will feel the same.
