Hi …i bought from eBay microsd SanDisk elite extreme plus 128gb up 100mb/s read 90mb/s write…but when I test this card is about 63mb read and 58mb write…its not even close 100/90mb…is this ok?

I test SanDisk 64gb ultra 80mb/s and speed are the same
I use A1 SD Bench tester

Here is same auction


it may be the reader you are using. to get the full speed you would need a high performance USB 3 reader. sandisk has one the sddr-289. what kind of reader do you have?

Yes …here was a problem my slot card reader in my laptop is usb 2.0…i bought card reader Kingston 3.0 usb and the speed was 91 read 82 write

Thank you
