    I bought this flash drive for its capacity and USB 3.0 which is supposed to give you a faster transfer rate. The problem is that the flash drive is rated at 100MB/Sec but only with read speed. Realistically, the read speed is more like 60-80MB/sec. But the write speed on this flash drive is a paltry 20MB/sec in real use. Copying 128GB of files to the drive took almost an hour. I could not figure this out until I went to the Sandisk site and saw that it does not specify write speed, just stating that the write speed, stating "Up to 100MB/s read speed; write speed lower and varies by capacity."

    I like this flash drive because it's got enough storage space for a lot of pictures and videos to download on and the download speed is pretty fast. I haven't had any problems with it

    My stereo reads USB drives. I've constantly upgraded capacity as sizes have increased. I'm currently using this drive and appreciate that it doesn't stick out too far from the dashboard.

    Needed Newer Larger Thumb Drive

    The housing on my old thumb drive began to fail and I have been looking for a new one. I like the SanDisk self-contained drive. Best buy had a good sale price on their range of drives. I decided to upgrade from my old 64 Gb to a 128Gb. Some reviews have lower ratings on SanDisk drives, but I have had many over the years and have never had a problem with one, much less a failure. I have a different brand Micro SD sitting on my desk that died and I have written to their customer service several times and NEVER received a response, but have had some usage questions about some SanDisk drives and got immediate responses from them. They have my recommendations.
