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

⭐⭐⭐⭐⭐ Fast, Reliable, and Compact I really like the SanDisk 128GB Ultra Flair USB 3.0 Flash Drive. It’s fast, reliable, and very easy to use. File transfers are quick, and the storage capacity is perfect for documents, photos, and backups. The sleek metal design feels sturdy and durable, and its compact size makes it easy to carry around without worrying about damage. It works exactly as expected every time I plug it in. Great value for the speed and storage. I’d definitely recommend it.

I bought the SanDisk Ultra Flair 256GB USB 3.0 to handle large media files and backups, and it’s exceeded every expectation. The transfer speeds are blazing fast—moving gigabytes of data in seconds—and it’s been rock-solid reliable across multiple devices. I especially love the sleek metal design: it feels premium, fits easily on a keychain, and doesn’t overheat during heavy use. Whether you're storing high-res photos, videos, or important documents, this drive delivers performance and peace of mind. No hiccups, no lag, just plug-and-play perfection. Highly recommend for anyone who needs serious storage in a compact, durable package.

I only use Sandisk USB Ultra Flair drives, maybe a Cruz here and there. Never had any problems with them, rock solid. They do get fairly warm, being so small. Really warm. But it doesn't seem to affect them at all, as I've have some going on 4 years now. Good storage at a good price.

This SanDisk flash drive is a reliable device for everyday storage. The sleek, durable metal housing feels solid in hand and easy to carry around. The read and write performance of this USB 3.0 is fast, ideal for the storage of movies and backup files. USB 3.0 is faster compared to USB 2.0 devices. It's also fully backward-compatible with USB 2.0 ports, but will operate at reduced speeds on those older ports. The connectivity to a USB 3.0 port or higher can achieve significantly higher throughput, which speeds up transferring large files like videos, photos, and backups compared with older USB standards. Some flash-drive lines come in multiple colors, this flash drive focuses on this metallic black/silver styling. Overall, it's a solid, budget-friendly choice for extra portable storage.

Good storage at a decent price. I needed to buy a thumb drive to create a windows reboot media. I know 256gb is overkill for that, but I'll eventually use it for storage. No issue at all. Plug it in. Computer reads it. Good to go. Decent speed. Be careful though as during the windows install the drive did get fairly warm. The drive is small (maybe too small). Solid plastic construction. Can't ask for much more out of a thumb drive

Very tiny flash drive. Easy to use. Held all of the files off our 10 year old laptop.

UPDATE: February 1, 2026: I have to update my review and change my rating from 4 stars to 5 because of something I discovered about the heat issue I first reported. First of all, I ordered this 128GB flash drive multiple times: (1st drive ordered on September 14, 2025; the 2nd on October 7, 2025; and 2 more on December 14, 2025) - and I found that the **heat issues disappear** depending on the peripherals that you connect them to. When I used these drives with my Targus Docking Station, they ran hot, but they're nice and cool with my Anker Powered USB Hub (7 Ports USB 3.0). I'm not a hardware expert, so I'm guessing that the reason that these drives run at such cool temperatures now with the Anker hub (with 7 ports) is that this hub has its own power source (meaning that it has to be plugged in to an outlet versus drawing its power from the computer to which it's plugged in), whereas the Targus dock's only power source is the computer itself. Also, just wanted to add a note about the reviews that said you have to download & install software to use these flash drives: Tip 1: **You do not have to do ANY of that.** You can simply reformat these drives on your OS and then choose whatever format suits you. Tip 2: If you want a perfectly clean drive, don't use any of the software that comes with any drive. In fact, MAKE SURE you reformat every drive as soon as you unpack it. You'll end up with a device that has nothing extra: no apps, no software, no spyware. There, problem solved. Personally, I began formatting every external flash drive & external hard drive that I recently bought as ExFat so that those drives will be fully compatible with both Windows & Mac OS (meaning that you'll be able to copy files TO and FROM the drives on both of those OS's). -------------------- For full clarity, the specific drive I ordered was the 128GB Ultra Flair USB 3.0 Flash Drive (SDCZ73-128G-G46, black), on September 14, 2025. I formatted this drive as ExFAT so that it would allow me to have read/write capabilities on both Windows and MacOS. Been using it for almost a month with both a 5-year-old Mac laptop (Big Sur), and a brand new Mac (running Sequoia), and it has zero issues with reading, writing, and transferring files from multiple NTFS external drives (which range between 6TB to 20 TB) and the MacOS versions mentioned above. I can play (and edit) large media files directly on this drive and can use it to interact with every filetype imaginable. (Will update this review in a week or so after receiving the Windows computer I recently ordered to report on how it performs on Windows). In terms of speed: Downloads sent to this drive had severely limited transfer rates. Switching the same downloads to an internal drive or other external drives immediately gave me far higher speeds than what the SanDisk flash drive could handle. One thing I'd like to add is that on Mac, this little drive runs very hot to the touch even when idle. After testing this, it seems that prior use bumps up the temperature and keeps it hot even after closing media files that were in use.

nice little thumb drive, love the capacity just wish it has a cover to keep dirt and lint out of the end thus the four stars, otherwise works great, no issues hooking up with our computers, would buy another when needed. I am going to have to update my review to a 5 Star as I left it in my pocket, my wife washed it, and ran it through the dryer. Came out clean and works great.

Use it daily for file backup's at work, nice and fast, no issues so far, very happy

Quality - very good Appearance - almost good Performance - awesome Connectivity - instant My favourite brand - SanDisk Must buy it. Thanks to the Amazon Team.

Es algo pequeña y el material plástico da la sensación de que con el tiempo se va a caer, sin embargo la capacidad es muy grande (aunque son 232 efectivos conta lo que se anuncia) y la velocidad de transferencia es increíble ya que moví un video de 233 MB de mi computadora a la USB en menos de 10 segundos (si así como se lee), aunque también puede que influya mi equipo ya que es una MSI con i7, 8 de ram y SSD, pero aun así es espectacular la velocidad de de la memoria

Jak za 70 parę złotych świetny pendraiv może nie za szybki ale wolny też nie jest. Zapełniłem całego w jakieś 4 godziny filmami i w sumie do odtwarzania filmów na TV został kupiony. No fajnie że metalowy a nie plastik fantastik
