SanDisk 256GB Ultra Fit USB 3.1 Flash Drive - SDCZ430-256G-G46, Black

For the price, it is an excellent buy. My only issue Ive had with it in the time I have used it is that I cannot copy a single file larger than 4 gigabytes to it. For example, I attempted to copy over a 7 gigabyte MP4 file from a streaming session, and my system told me it was unable to move the file because it was too large. Keep in mind that I have only used 20% of the space on this 500Gb drive at this time. With that said, the times I need to use this drive for a file of that size are very rare, so that is not a deal breaker for me. I mostly use this as a backup drive for my files after all. All in all, great buy. But if you need to use this for very large files, you might instead need an external drive rather than this.

I love the size. It is quite tiny and can be hidden almost anywhere. For securing information this is the optimal size.

Worked instantly out of the box. It wanted me to download some sketchy Mac software but it works perfectly without it.

Its seems pretty good other than it wont work for the primary reason I bought it. I purchased the 512gb version for a MCU2 Tesla to store video from the dashcam and sentry systems. Unfortunately the information system will not recognize it even after trying multiple formats and other troubleshooting. I got a micro SD in an adapter to work fine, but not this USB drive. Seems to work great in my Linux and Windows based computers, just but the Linux system in the Tesla.

Very accurate

Very small, attractive package with rounded edges and big storage capacity. To think how much memory devices have improved! Comes with useful vault password-needed software to protect files. Two thumbs up.

Drive would not accept 6gb. 5.7gb video file. Smaller files (1gb) no problem. See future headaches w this contriction. Other 256 usb drive I purchased worked fine.

The item works great. They both broke but are still usable. I wish they were metal. I do move them but not a lot so they shouldnt be so brittle.

SanDisk is generally my go to for flash drives & SD cards. So far they have not let me down. These drives are great to use in applications where you just want to plug it in & leave it there. They dont stick out to get in the way. I got one to load my music collection to use in my cars infotainment system. I just plugged it into the usb port & it stays there w/o getting in the way. Since then, I started using these for a few raspberry pis where I wanted bigger, more reliable storage you can boot from them ( you may need to flash a newer BIOS). If you are looking for a flash drive to carry around, Id either attach this to a key chain or something using the lanyard hole, or go with a physically larger drive. These are small enough that it could easily be lost w/o noticing

This is my second time buying the disk on key 512 GB by SanDisk. The product arrives with about 50 GB less they are occupied for system files and background stuff. I noticed while transferring photos and videos that it is pretty slow lower to be precise slower than I expected it to be after running a few tests. I found out that my discount keys are running slower than advertised on the package and in the description. Overall I am going to be using these due to the fact that they still have a decent amount of storage for my usage and their size which is the biggest perk in my opinion.
