SanDisk 128GB Ultra Flair USB 3.0 Flash Drive - SDCZ73-128G-G46, black

Fast, compact, and works exactly as expected. Transfer speeds are solid with USB 3.0, and the metal casing feels durable. Just a heads-up note it does get a little hot during use, but nothing too concerning. Great everyday drive for backups, file transfers, or media storage.

So far so good. I bought these to replace my old SanDisk nub drives that failed by getting too hot. These are incredibly small but seem to work fine. I wanted the smaller drive size of 32 GB to use as install USBs with Rufus to install Windows 11 and to have as a recovery drive for Windows 10.

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.

Once again SanDisk has a solution... We wanted to be able to keep a copy of all our photos and files without placing them in "the Cloud" since we are often off grid while traveling. This "Thumb Drive" allows us to safely and completely back-up everything we photograph, write up and develop until we return to civilization and connectivity. Enormous capacity at a low price, perfect solution.

Why did you pick this product vs others?:Good thumb drive for data with a large capacity of storage.

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.

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.
