For more than 25 years, SanDisk has been known for quality and reliability all around the world. That's why your flash drive comes with a five‐year Review: Excellent for creating bootable USB drives and formatting; fast and reliable. - I bought this 64GB USB drive specifically to create a bootable drive for formatting and reinstalling the system on my laptop, and it met my needs perfectly. The transfer speed is noticeably better compared to other USB drives I’ve used in the past; creating the bootable drive didn't take long, and I had no issues with the laptop recognizing it or booting from it during the installation process. It has a compact design with a retractable connector—preventing the loss of a separate cap (a common issue with other drives)—and feels well-built despite its small size. After using it for the system reformat, I continue to use it for file transfers without any problems. I recommend it if you're looking for a reliable USB drive for PC/laptop maintenance tasks, such as creating installers for Windows, Linux, or other operating systems. What I liked most was that it worked flawlessly for creating the bootable drive, offered good transfer speeds, and featured a compact design with a retractable connector. So far, I haven't encountered any issues with how I've used it; it lived up to all my expectations.

The raw capacity was 248,437,014,528 bytes. **Q: Does this flash drive have a slider to retract the USB port into the casing?** A: Yes **Q: Anyone had this for 3-5 mos or longer and still happy with it? Still working well? Thanks in advance!** A: Works perfectly and fast. Nice even loading between 21MBPS & 31 MBPS. I t settles in evenly somewhere between these numbers and loads in almost the exact number all across the (in my case) music until they are are all loaded. In my case about 28MBPS. I use NTFS file format. Perhaps exFat may be a little faster of slower, I haven't tried it as It was fine and I didn't want to format the drive just to find out. I did a fast format at the start to leave the drive completely empty as I didn't need locked security. I am 'assuming' it works as advertised. Playback was flawless. Function fallowed fit which was just right from Rxer, to car, to PC. No sloppiness or 'collapsing' when inserting drive. I've found all Sandisk's to be well made, and most important, reliable, for years but this specific model has very little heat build up and 'all in all' is the best I've ever used so far. The exact opposite of a certain brand starting with a 'P' which runs hot and is guaranteed to eventually fail and the loss of about 5600 songs can be devastating. Getting the songs to run in the exact same order as recorded on the CD is a continuous problem and I haven't figured out yet to set that and all USB's seem to do it. I'm fairly sure there is a way but I haven't found the exact way to do this on any brand. Suggested solutions gratefully appreciated. Aside that, this is a winner and at $11.99 new, a very good deal. A year+ so far and no problems, Paul **Q: Does it read as a hard disk drive or removable storage when plugged in?** A: Removable storage. Unless you use it as a Windows To Go drive, when it would be read as a hard disk drive. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent for creating bootable USB drives and formatting; fast and reliable. *by L***S on July 25, 2026* I bought this 64GB USB drive specifically to create a bootable drive for formatting and reinstalling the system on my laptop, and it met my needs perfectly.
