SanDisk 128GB Ultra 2 pack.
I've purchased a number of SanDisk products over the years and have yet to be disappointed. This is my first purchase of the Flash Drive Ultra and I find the quality and performance to be excellent. Speed is good and well within the benchmarks stated as far as read/write speeds. I'm not real crazy about the thumb open / close mechanism allowing dust or other foreign matter to infiltrate the Male USB port insert, but I guess time will tell. At this price point per drive, I don't really have much to complain about. I generally do a visual inspection of my drives anyhow, so blowing dust particles out or using a Q-tip dipped in Alcohol to remove any debris is simple enough. The instructions are straight forward and easy to understand for even the most untechnical amongst us and the RescuePro Deluxe Software included is a very nice feature for when those magical "OOPS!" moments occur. I think most of us have had at least one occurrence that left us scrambling for data recovery software after a drive was corrupted or an accidental deletion of files and folders that bypassed the desktop Trash Bin. The application comes with both Mac OS and Microsoft compatible versions ready to install from the disk as well as a download link for any additional copies. Registration / Activation is inscribed on an insert inside the drive packaging. Open the drive packaging carefully to keep this vital information from being damaged. A free One-year, Single user License is a pretty decent deal. Photos: 1.) SanDisk 128GB Ultra 2 pack. 2.) RescuePro Deluxe, 1 Year Free W/ Registration Key.

Lots of storage in a simple, reliable drive
This SanDisk drive is an easy way to add a ton of portable storage. It’s compact, works plug-and-play, and transfers files quickly for everyday use (photos, videos, backups). The sliding connector is convenient so you don’t have to worry about a loose cap. Great value if you need a big USB drive for storage or file transfers.

💾 SanDisk Ultra Flash Drive: A Great Project Drive (Not Your Life's Archive!)
I love a good flash drive—it's the only place I can confidently move all my digital projects and old files without them cluttering up my main computer! This SanDisk Ultra 128GB drive is fast, reliable, and can hold a good chunk of data, but let's be realistic: at 53, 128GB is barely enough to store last weekend's vacation photos, let alone a lifetime of pictures and videos. It's a project drive, not a digital archive! It's the perfect size for backups, moving massive files, or carrying around that one embarrassing PowerPoint presentation from 2005 that you can't bear to delete. 😎 Cool/Unaware Fun Fact: The Secret Agent Drive! Did you know you can use this drive to turn any public or work computer into your own private space? You can install an entire portable operating system (like Linux) directly onto this drive. Plug it into almost any computer, boot from the drive, and you get your own personal desktop, complete with your files and settings, without touching or leaving any trace on the host machine! It's a great tool for a man who needs to organize his projects better and access them anywhere. Try that with a floppy disk, Grandpa!
