128GB 10-Pack Ultra Flair USB 3.0 Flash Drive (10x128GB) - SDCZ73-128G-B10CT, Silver

⭐⭐⭐⭐⭐ 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 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.

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.

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.

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

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.

Speedy delivery and nicely packed without sign of abnormality since first usage. Thanks Amazon

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
