SanDisk 512GB Ultra USB 3.0 Flash Drive - SDCZ48-512G-G46, Black

Very easy to use, extremely fast and no issues in my use !

I’ve used this drive to download and run dozens of VM‑based home labs without touching my internal SSD, and it delivers exactly what I needed. The 512 GB capacity gave me room for over a hundred ISOs plus snapshots, which is ideal when working on multiple cybersecurity simulations. With sustained read speeds up to 150 MB/s, transfers feel instant, even when copying 20 GB lab appliances between USB and host systems. This SanDisk 512 GB stick is exceptionally reliable, secure, and spacious, exactly what I needed for my cyber‑lab setup.

Great value for a well-known brand and for such large storage capacity. Glad that I purchased it.

A lot of other cheaper USBs don’t work well. We mainly use these to load videos to play on large monitors. These USBs can handle large videos of high quality, they are fast to transfer, and recognized even on our older monitors. Yes, they are going to more expensive but after having tried out cheaper USBs that would sometimes play and sometimes not, I highly recommend biting the bullet and just purchasing these because I know I don’t have to worry about reliability!

Good item. Sadly it is slower than most newer usb C units. The security software works, once you download the required update, but make sure you place it on the thumb drive, instead of on you hard drive

These USB drives are exactly what I needed. They’re compact, plug in easily, and transfer files quickly without any issues. I haven’t had a single error or connection problem, and the build feels solid and durable. Perfect for backing up documents, photos, or moving files between devices.

Perfect for loading my music to these and playing it in my the car. I have had other USB flash drives that do not work well in the car or will not play at all. These play everything on the USB. Love it! Very fast transfer to the USB and easy to use. Will buy again. The price is great!

I only use SanDisk thumb drives. I've found them to be the most durable and reliable and can be updated. Also prefer the private password protected partition this model has.
