SanDisk 64GB 10-Pack Ultra Flair USB 3.0 Flash Drive (10x64GB), Non-Retail Packaging - SDCZ73-064G-B10CT

The SanDisk 256GB Ultra Flair USB 3.0 flash drive is everything I was looking for in portable storage. It's incredibly fast, with noticeable speed when transferring large files—especially compared to older USB 2.0 drives. I regularly move HD videos and large documents, and this drive handles it with ease.The sleek black metal design looks great and feels sturdy. It's compact enough to carry on a keychain or in your pocket without adding bulk, and it doesn’t heat up too much during use, which is a big plus.At 256GB, the capacity is more than enough for work, backups, or media storage. Plug-and-play setup was seamless on both Windows and Mac.If you're looking for a high-capacity, high-speed USB drive that’s both stylish and reliable, this is a fantastic choice. SanDisk never disappoints!

I bought this wonderful flashdrive for my students graduation gift. I also included a huge amount of files for him to use with his 3d printer. Fast to download files, read the files, fits in your pocket and has a high storage capacity. Great quality product that you can plug in and take out easily with any computer. Works great.

It is super small and works great. I used this in my Tesla to record the video from the car and it works great. It is smaller profile than the other USB flash drives and works well. Also great for the price.

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.

Good, durable, fast… excellent

Fast, Compact, and Reliable Storage SolutionThis SanDisk 64GB Ultra Flair USB 3.0 Flash Drive has quickly become my go-to for transferring and storing files. The first thing I noticed is how fast it moves data—USB 3.0 speeds really make a difference compared to older drives. Large video files and photo collections copy over smoothly without long waits.The design is sleek and compact, making it easy to keep on a keychain or slip into a pocket. The metal casing feels solid and more durable than the all-plastic alternatives I’ve owned in the past. I also appreciate that SanDisk includes SecureAccess software for those who want to password-protect files—handy if you plan on carrying sensitive documents.One thing to keep in mind is that the metal body does get a little warm during heavy transfers, but it’s never been uncomfortably hot in my experience. Also, as with any small flash drive, it’s easy to misplace, so I’d recommend attaching it to something you won’t lose.Bottom line: A fast, well-built, and portable flash drive that offers excellent performance for everyday file storage and transfers. Great value for the price.

I keep it on my keychain (pro tip - take it off when using) for uploading photos from my computer to my college photo lab computers. It can get a little toasty during long usage.

This would, of course, be considered a very small capacity drive these days (mid-2025), and if I needed something for serious backup I would buy a much larger one. But sometimes I don't need the raw capacity, and it makes more sense to buy a small, inexpensive drive to match the application. I bought this one to save an iso of my current installation to preserve one application with a feature that has been deprecated in newer versions.If the small capacity is enough for your needs, this is a good little stick.
