Hi

Does w510's integrated sd reader support UHS-I class speed or just class 10?

    I used a UHS-I card on it so it works fine

    I'm well aware they're backwards compatible, but i want to know whether it surpasses the speed of class 10 or it just works as a class 10

    classes are just the speed of the sd card it doesnt have an issue with the sd reader it will also take micro sd xc as well its been proven and testedmost sd cards start at class 4 which is the lowest speed

    My testing with various devices showed a UHS-I (i not 1)  in the W510 to have a sequential read/write of 23/9 MB/s. In comparison the internal SSD runs at 58/27, 16GB Lexar flash drive at 16/4, and a USB 3.0 SSD (not in the W510) at 228/48.

     

    The CloverTrail chipset is limited to USB 2.0 and the SD socket connection seems about the same.

     

    Similarly a WTG drive takes about 38 seconds to boot in a USB 3.0 environment and about a minute on the W510.

    Thank you for your detailed answer, but i'm preety noob at storage benchmarking . My class 4 microSD reaches 8.5mb/s while writing a big file. I'm not familiar with the terms so can you tell me what speeds it can reach with big files, like a movie?

    I'm asking this because i've seen on the clovertrail specs that it has a version 2.0 reader and uhs-i class speed is available on version 3.01 according to wikipedia
