SanDisk512GB Ultra Flair USB 3.0 Flash Drive - SDCZ73-512G-G46,Black

I have bought these multiple times. I am able to put files on the drive and give them to friends. They work as described. The transfer speed seems to depend on the device. Newer more powerful MacBooks the speed is very fast. Older devices take longer. It has more to do with the device than the drive. I have never had one corrupt or fail.

This is a great flash drive. Lots of storage at 128 GB. Read/write speeds seem to be very quick. This drive is small. When it first arrived I thought I ordered the wrong thing because the entire drive is as wide as the tip of most drives. I like the hook at the end because I can clip it to a key chain or to the hook in my back pack and keep track of it easily.

This little flash drive is a workhorse. Transfers are quick thanks to the USB 3.0, and I’ve had no issues with corrupted files or overheating. It’s tiny enough to carry on my keychain but still feels sturdy. Great option for anyone who needs to move large files fast or just wants a dependable backup tool.

Thought the 512GB was a counterfeit. But have proven it's not using simple tools that did write/read testing. For the most part, I got about 50-60MiB/s Write, and around 100-160MiB/s read, sequentially. Formatted (ExFAT/NTFS) it's about 460GB which has provisioning for extra spare blocks to lengthen lifespan and speed. Overall. I give is a 4-stars. 5 for being what they said it is, 4 stars for the slightly slow write speed. This is because the drive is fresh, and this definitely isn't NAND memory. Even TLC NAND is faster, but it may be adequate enough. For my wife, long-term photo storage is what I got it for, and it'll fit. Not only isn't small, but the relative storage size is huge, and cheap, and I can see this used for a lot of trading media or swapping out backups overtime cheaply. It's likely many degrees higher able to survive fires in a fire lock box than a hard drive, and tiny enough to throw on a keychain for imaging with something like ventoy or a quick and dirty linux/windows boot disk. It seems to be of decent sandisk quality, and time will tell, but maybe for a single or dual-disk raspberry Pi server, or even a server intenal boot disk for diagnostics/headlsess server, this is likely a great use for that. it's fast enough for a raspberri pi 4 and small enough to not be a nuisance. also great if you have a car that needs to offload dashcam footage like a tesla or some retrofitted car entertainment systems. It doesn't generate too much heat, even after me running full tests, and can be used as a quick and small OS X bootable disk if you are at a university with a lot of storage space. They seemed to have design some reliability thinking with the spare blocks being reserved, meaning it should last a long time. It should be able to do most file systems, but for FAT32, you may need to create a partition for that, but you can do a lot of 32GB FAT32 partitions if you need to, and reserve the rest for Linux, MacOS or Windows-based filesystems for bootable and other data seperate. Could be used to make a kiosk in public too with right tools while being able to hide it, or pull it quick.

I love this. Until now I used other sorts of USBs, the kind where you have to pull up or pull out to open and close. They used to stick out. This one won't break, I don't see it as being possible because it goes straight in without any pulling. The size is small enough that I can leave it in my laptop all the time and it doesn't get in the way.

What's convenient about this flash-drive model is that it is so sleek and small and carries just enough data storage that it's gotten me pretty far on my personal projects. Because I get out now and then I've found it a huge success when I use other computers. It can be really convenient when you need to store backup data. My only warning when using this tool is that it's easy to misplace because it's so small.

Best flash drive I've ever owned. The read and write speed is fast and haven't had any issues with it. No issues with the TV reading it either.

I needed a USB drive with more memory than my old ones and this fit the bill. Worked great to help me update my Kia's infotainment and navigation system.
