    I always purchase SanDisk products. The reason I bougt this flash drive was because of the color red. Easy to tell me what info is in the drive. Tired of using other black and white colors. Also the drive is safe and reliable and had no problems with it.

    There really isn't much more to say about a flash drive. I needed a big one to put my iTunes library on and this should have enough space to grow for several years. (Current library is 38 gb)
