exFAT (delivered) NTFS
read 44 MB / s 48 MB / s
write 14 MB / s 15 MB / s
While this corresponds to the manufacturer's instructions but is really not up to date. Because I need a faster card, I'll grab times for Lexar in 633x.
My review for Lexar:
OK, the card is indeed noticeably faster than with itself capacity of SanDisk, but who at least not so exaggerated in the speed information and are 20% cheaper.
Instead of the promised 95 MB / s this card reached unfortunately only:
EXFAT (delivery state)
Reading 66.1 MB / s
Writing 20.8 MB / s
These are indeed write 50% more than in the 20% cheaper SanDisk, for reading but only 25% more, and considerably less than promised.
Tomorrow I test whether it's up to the formatting or the supplied adapter ...
Update 2/21/2015:
At the included adapter, it is not. The new measurement with a Transcend adapter that provides 150 MB / s, performs virtually the same results:
EXFAT (delivered condition) NTFS
Reading 68.1 MB / s 70.4 MB / s
Writing 21.0 MB / s 21.0 MB / s
Conclusion: Lexar exaggerates when the speed information, SanDisk makes honest information.
Oh, an afterword for skeptics: The test hardware used so far achieved with the fastest measured USB3 device 240MB / s read and 200MB / s write.
