    If you are looking for a great backup to store your files, this is the thumb drive to purchase. I always buy the 128 gb thumb drive because it is a great deal. It was only a few years ago, when the best deal on a thumb drive was around $30 for a 64 gb thumb drive and now, for that same price, the storage has doubled. Only get this when it is on sale, but if you need a thumb drive and this one isn't on sale. then go with a PNY thumb drive. The sale price tends to change week to week between these two brands, so there is no reason to buy a thumb drive at the regular price. I also found that these two brands of thumb drives are reliable, so you are getting a good product at a great price.

    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."

    Its always nice to have a lot of extra memory on hand to back up my drives. I work on several computers and to have 120 Gigs on a flash drive is outstanding. Great little drive at a great price.

    Fast connection. True USB 3.0. For 128GB is more than enough to cover mp4 and more than enough for files.

    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.
