my overall consistent write speed.
Kingston 64GB 10 mb/s
Kingston 32GB 10-12 mb/s
Samsung 32 and 64 GB 14-15 mb/s

maybe my speed is significantly slower because I am using those cheap $1 microsd usb adapter for the cards, and connect it to the computer front panel USB 2.0 port. later, I test the speed with it inside the handphone to a laptop USB 3.0 port.

Then that might be even more skewered. Try the adaptor on the USB3 port... But seems like ur hardware is the real bottle neck here. Get a good USB3 microUSB adaptor... I can get you one for ~10 or less i think...

Hi guys, I have a doubt. Now I have 1 samsung micro sd class 6 & 1 scandisk class 10 which 1 is faster?

Based on what we know, The SanDisk Class 10 should be faster, assuming that your series and our series are the same.

card inside handphone speed is slower ?

I did a test with the card inside the handphone to another computer ( laptop ) USB3 port, transferring 1GB+ video files. Samsung EVO 32 GB averaged read speed 16-17 mb/s and write speed 14-15 mb/s. it's the same speed result as on my usual computer.

I did a full H2testw with another Samsung EVO 32GB card on the usual computer.
no errors
read speed 17.7 mb/s
write speed 14 mb/s

think must buy a good USB3 microUSB adaptor.

Yeap. Also, another thing to note is that format of card also plays a role. However, your card is still alright, meeting all the rated specifications (Class 10, UHS Grade 1)

I have yet to see one of that. Thanks for sharing the results.

class 10 is the normal standard. UHS is the one to differentiate

The Class also helps to differentiate. Class 10 is not the normal standard. They are all standards. The only diff is that CLASS stops at 10MB/s of minimum read write. UHS GRADE has only 2 - 10 and 30. So it technically is just a rating. Many cards with UHS grade 3, typically has double the minimum required. So my benchmark helps you to differentiate that.

This review says otherwise, only read is doubled, write remains the same for their 128GB.

Its the same for the EVO and other 128GB cards. Its because of the controller and structure of how they made it.

That is why i say, 32GB =/= 64GB =/= 128GB wor

Yah i found the class 10 system messy, can be class 10 but of different read/write speed~ :s22:
