Performs as expected. I bought for mi Galaxy S3 to increase it storage options, when I need to transfer big files I use a usb adapter since the wifi and mtp conectios speed is far slower than directly connecting the device but that is not the cards problem. Its fast reading and writing inside the S3 and when connected to a current generation computer.Old computers will read and write at slower speeds, but is still compatible hardware wise. The exfat format can be a hassle.No problems yet hardware wise. I would have preferred an open standard as partition format instead of exfat, but that is Microsoft fault not Sandisk.Is easy to reformat with a USB sd/micro-sd adapter.
