SanDisk Ultra 64GB SDXC Memory Card, Up to 120 MB/s, Class 10, UHS-I, V10

Product Information

Up to 150MB/s read speed, engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, require compatible devices capable of reaching such speed. Write speeds lower. Based on internal testing; performance may be lower depending on host device, interface, usage conditions, and other factors. 1MB=1,000,000 bytes. BEWARE that if the pen drive has NTFS File System then it won't work with mobile phones, tablets, laptops which don't have Windows Operating System. Same way, if you format the pen drive for Linux OS File System, it won't be recognised on Windows laptops, Android phones, tablets, etc.

Benchmark Crystal Disk mark scores for a file transfer of 500 MB size were 34 MB/s -Read & 19 MB/s – write which looked like a mere consolation. Transfer between my Samsung S7 mobile & S2 tablet too was not fast. I had never expected it to be this slow in this modern era of 2018, thus finally I decided to return it but I suppose I will only get a replacement & not reversal.

Customer reviews

MOBILE PHONES: The pen drive works with Android OS of Mi phones such as Redmi Note running Android including old Android Version 9 as well.

With your Linux system's file format, you will have better storage space than any Windows File System.Approximations: Results and Full HD (1920x1080) video support may vary based on host device, file attributes, and other factors. STORAGE : Out of the total name plate rating of 64 GB , the actual allocated space for usage is around 57 GB which is ok enough. But For Example, If you have decided that you won't use it on mobile phones or tablets because the fitting is too tight and you don't want to risk damage to this point which is primarily used for charging - then go ahead and format the pen drive for your laptop. STORAGE SPACE: Just as in external hard-disk drives, the actual usable storage space will be less than what is mentioned on the product. SanDisk Ultra® microSDHC™ and microSDXC™ UHS-I cards are compatible with Android™ smartphones and tablets, Chromebooks, and Windows® laptops. Just insert the card to instantly increase available storage space—at a great value relative to alternatives. New Windows® convertible and ultra-light laptop users, in particular, who were accustomed to the multiple terabytes of storage common on larger laptops will appreciate cards enabling more private physical storage.
