    I bought this flash drive for school. I'm able to make large files portable and moving them back and forth to class is quick and painless. I never seem to have issues with memory from SanDisk. I try to buy their products first, it all depends on cost.

    I can always rely on SanDisk. I've used their products for twenty years now. I've never had an issue with all of the memory cards, thumbnail drives, & portable data storage drives from them.

    I have never had any problems with any of my SanDisk - Ultra USB 3.0 Flash Drives. Be patient if backing up huge amounts of data. Their write speed is a little slower than their read speed.

    I've use San Disk since high school and they never fail me. I use this USB to store media files for my Roku 4 & does as expected. I love how fast the file transfers. If you plan to drag files more than 4gb when using a mac, there is an extra step to be taken.
