    The price on this was a great buy. The write speed, along with the retracting USB and key-chain hole make carrying 128GB of files a snap.

    SanDisk continues to provide good reliable storage. This time around, I opted for more capacity due to the low price. I plan on backing up around 40,000 emails.
