    The SanDisk Ultra 512GB USB 3.0 Flash Drive is super fast and holds a huge amount of data. Transfers are quick, even with large files, and the retractable design is a nice touch — no cap to lose. Perfect for backups, videos, and everyday use. Great value for the storage size!

    Great buy. I bought 512GB flash drive because it was on Sale and 1TB was more than 2x the price. It works great although the set up instructions on tge Web are hard to follow because the site covers all products by Westgate who own Sandisc.

    I can't confirm how much space it holds; I'm just using it for storing videos and the write speed is good, read speed is very fast, no problem watching the videos I saved on it. Small and I like that the usb part is retractable. Hard plastic case seems sturdy. You can add a lanyard with the hole at the end.

    I bought this USB flash drive to expand storage on my Insignia Fire TV. (Found out later that the TV accepts a maximum of 64GB for flash drive expansion.) I'm now using this 512GB flash drive to back up my laptop. Really fast, small and convenient. Highly recommend!!

    I couldn't get Ventoy to partition this USB drive into 2 parts, one for Ventoy bootable code and the other for iso files (in my case F: and G:) I've done this activity before, now setting up boot recovery for my daughter's college computer. After some fussing I decided to run FakeFlashTest on it. It has a chunk of corrupted blocks that make it unpartitionable for Ventoy work. See image of FakeFlashTest resuts

      Hi Richard,

      We're sorry to hear about your experience. This issue could be related to incorrect file format or partition issue. We suggest reformatting the drive in exFAT file format(https://support-en.sandisk.com/app/answers/detailweb/a_id/20821) before use. Note: Reformatting is a data-destructive process, ensure to backup your data before reformatting. If the issue continues, please get in touch with the support team for further assistance by opening a ticket at (https://support-en.sandisk.com/app/askweb) SanDiskConnections
