SanDisk Cruzer Ultra 16GB USB 3.0 Flash Drive SDCZ48-016G-U46 up to 100MB/s (Pack of 5)

Although only 16 Gb, they were perfect to use as bootable OS flash drives.

Half of the rear of the device is hollow on the rear when extended. I have some a little older and the build feel 10x better. When retracted the plastic slider fill the hollow void on the rear. Wanted these for music but will be returning due to the over dumb design

Nice middle grade drives. Check the specs to make sure the speed is OK for you. Not sure what Thickness and Warmth is for a USB drive, Amazon, but 5 stars all around!!

A nice small sized drive to store all my utility apps on. Great to have when working on other computers.

After 3 attempts to find a flash drive that would record from our digital audio mixer without stopping intermittently, I went back to SanDisk. Performed flawlessly-all 5 of them.

Large size - Fast upload, best price for usb of this size. - pack of 5 perfect. Believe me, I searched long and wide needing many to upload genealogy files/photos/videos for each of my family. These worked great.. and again - super fast transferring. I keep ordering this product set.

Excellent buy for the brand SanDisk

I liked the reliability and its design.

Im a professional photographer and much of my work is delivered via USB-3 Thumb Drives. SanDisk is the most trusted brand in solid-state media and my go-to brand for USB drives. I have been using SanDisk Cruzer Ultra drives in 16, 32, and 64 gb sizes without a single failure for many years. You should know that a 16 GB Thumb drive does NOT provide 16 GB of data storage, I will never understand that is, but you are limited. Each drive has to reserve space for firmware and that drops your drive capacity, so purchase a drive that has a capacity far above what you actually need. Limited file size has nothing to do with the USB rated size, but is due to the formatting These Drives come Formatted to FAT32 that means a single file cannot be larger than 4GB as formatted. BUT YOU can re-format the drive with Windows. When you place the thumb drive in your usb-3 port on your computer, you can right-click the drive and select FORMAT, then instead of FAT32, Choose NTFS and you can then add large files to the drive. I do a lot of cinematic/video presentations and have had to re-format the drives for those larger movie files. I like these drives and the USB connection is retractable, BUT, it is still exposed to dust and debris that may be in your pocket, I highly recommend that you also purchase some sort of case to put your drive in when its not in use. I personally use the CaseLogic zippered cases for storage, mailing and transporting my valuable data-loaded SanDisk Flash Drives. I would definitely recommend them! They are the best combination of price, quality, and performance.

Device is too wide for my USB ports. Cannot use two side by side.
