Overall Review: I purchased two of these flash drives in July of 2020, received them 31 July 2020. They worked perfectly at first. I use them with rsync to back up files on my desktop computer running Linux Mint 19.3 with the MATE desktop. Last week when I tried to mount one of them to update my backup, one of the flash drives would not mount. I tried it in several different USB ports (some direct to motherboard), including some on my husband's computer (same op system, newer hardware), but no luck. The second flash drive still works (so far). I called Sandisk this morning to see if they had any ideas, but their response was that their flash drives were only for use on Windows or Mac systems. So warning to Linux users -- don't buy Sandisk.

Pros: I have two of these. They work well for transferring files or using as a bootable USB drive.

Cons: Gets quite warm, but it doesn't seem to affect performance.

Overall Review: Would buy again.

Pros: It holds the full capacity and at advertised performance.

Overall Review: I would recommend to others and get another one when I need it.

Overall Review: SanDisk is worth the couple extra bucks. Very reliable. Quick data transfers. Use for OS installations, other ISO files, data transfer & storage.

Pros: - fast when using with USB3.1 connection - low cost - the right flash drive for the one task I required: make a recovery key for a Win10/Lenovo laptop

Cons: - None that I noticed

Overall Review: It's very small, so my secondary task is to remember where I stored it in case recovery is ever needed.

Pros: Good storage size (512GB)Small physical size - fits easily on key ring without adding much bulkFast USB 3 speed

Cons: none

Overall Review: Good product - I would definitely purchase another if I need additional storage, but at 512GB it will be awhile before I need more.

Pros: I like the way it looks and feels.

Cons: Write speed is disappointing, but I'm seeing reviews for other flash drives that note write speed as being slow. I use it to create a copy of a file that's approx 60GB and it takes an hour or more to copy.

Overall Review: Has a sleek appearance. Its small size makes it easy to use in ports that are close together. If you want to load large files, you'll need to format it to NTFS.
