SanDisk 32GB 3-Pack Ultra USB 3.0 Flash Drive 32GB (Pack of 3) - SDCZ48-032G-GAM46T

I use one of these to transfer files between 2 laptops. A second one has portable apps on it so I can use it with several desktop and laptop PCs. The third one has Ubuntu Linux on it that I used to install on a couple of laptop and desktop PCs. All have worked well. I recommend these.

Liked everything. Held a lifetime of videos.

This USB was reasonably priced and the upload and download times were fast.

Pros: - Value for Money: With three 32GB USBs for roughly $15, the price-performance ratio is quite compelling. - Read and Write Speed: The flash drives deliver 160MB/s read and 40MB/s write speeds, which are satisfactory for most daily tasks. Cons: - Variable Quality: While I personally did not encounter any issues, there are user reports of defective units in some batches. Conclusion: - The SanDisk 32GB 3-Pack Ultra USB 3.0 Flash Drives offer good value and reasonable performance, making them a cost-effective solution for those in need of reliable storage. However, if speed is of the essence for you, investing in a M.2 Gen4 enclosure could deliver significantly higher read-write speeds, upwards of 800MB/s. This pack is a good choice for everyday use, but speed enthusiasts might want to consider the latter option.

I prefer covers vs in & out buttons. But I tried one of the drives by transferring 3 movies to it and then playing them on my big screen TV and it worked perfectly.

See above.

I used it once to install windows 11 on a new PC. It worked and is fast. Pny is a reliable company. This drive will sit around until I need to reinstall Windows. Not much to say here. The metal USB bit retracts for protection, I guess thats what its for. The end.

Nothing new here, just the results of my initial tests. TL;DR: Seems genuine, no bad sectors. Only 460GB, not for people in a hurry. Verify a SuperSpeed connection. lsusb -v shows: ------------------------------------------- idVendor 0x0781 SanDisk Corp. idProduct 0x5581 Ultra iProduct 2 SanDisk 3.2Gen1 ------------------------------------------- One USB 3 hub detected this as HighSpeed and another SuperSpeed.

great for masking signal from source not authorized to use

It very quickly copied pictures from my picture frame so I can take it to have pictures printed.
