    I usually buy SanDisk flash drives and I am willing to pay sometimes even a little more to get the quality. This time I really wanted to have the 128GB size as more and more I am backing up tons of digital photos. The smaller drives are good for documents but it is amazing how important getting the larger storage capacity means for safe back up. I recommend this product.

    I got this on sale for something like $90 off regular price. 128G of space is huge for a thumb drive. It’s USB 3.0, and is decently fast for what it is. It is generally faster than most USB drives that aren’t actually SSD on a stick. Perfect if you install Linux on it so you can have it portable between computers. Just plug it in and boot from it. Also perfect for use with a Raspberry Pi - it’s a bit faster than the SD cards.

    Bought it for a MacBook Air with only 128 gb. This is a cheaper alternative than adding more gb to the mac.
