- Reviewed in the United States on June 21, 2025Size: 128 GBVerified PurchaseI got this to upgrade a firestick for an older relative along with a cable and an upgraded power brick that will power the firestick AND the memory adequately. Works great after I removed apps from the firestick and had it install them on the USB memory. No more old hag whining that her korean soap operas on net flicks keep buffering and are slow to load. totally worth it. I did need to use aomei partition assistent to reformat it before the firestick would see it...windows tool wouldn't work.
- Reviewed in the United States on June 22, 2025Size: 128 GBVerified PurchaseGreat fast and compact portable storage drive. Easy to carry anywhere and plug in. It also feels well built and doesnt have a cheap feel. Also like the minimalistic design just being simple black. Also has a keychain hole so that you don't misplace it.
- Reviewed in the United States on May 28, 2025Size: 128 GBVerified PurchaseI bought this USB flash drive to use with my Blink camera and doorbell system's Sync Module 2 for storage and in case I don't want to pay the subscription fee. Blink has a flash drive but it is only 64GB. I wanted a larger one and since I love Samsung products, I got this USB drive in 128GB size. It came in the recommended format ExFAT and meets all the requirements for Blink's use. I just plugged it in to the module and it was immediately accepted and in use.

- Reviewed in the United States on June 21, 2025Size: 128 GBVerified PurchasePriced right. Faster than a jack rabbit on a date. Great low profile. Bought several of these drives over the course of months. No issues noted. Would and probably will buy again.
- Reviewed in the United States on June 11, 2025Size: 128 GBVerified PurchaseThis is a great thumb drive, but I discovered that it will not work in most car stereos because it is bigger than 32 GB, and thus, cannot be formatted to FAT32, which is required for most car stereos. I'll find a use for this, but it won't be for what I originally wanted it for.
- Reviewed in the United States on June 15, 2025Size: 256 GBVerified PurchaseVery compact / low-profile. Works as advertised, decent transfer speed. I use this for storage of all my tunes for use in my Audi Q5 (it has a USB-A port which can be used for this purpose).
- Reviewed in the United States on May 15, 2025Size: 256 GBVerified PurchaseI would not call these fast, but I do like the size. I use them on Dongles to archive content from my portable devices. And for that they fit the bill. Because i am not doing a lot of small read/writes I would expect them to hold up over time. I have a few that I have had for more than 5 years with no issues so far. I also use the BAR drives about the same price. I like these better. If you are looking for the fastest performance these are not it.
- Reviewed in the United States on June 5, 2025Size: 128 GBVerified PurchaseWow, fast and small. I'll leave it in my laptop all the time to run a virtual machine. I've bought three other sticks but didn't pay attention to the speeds and so they were all cheap and really just USB 2 speeds. Finally, I have a small stick that gets great throughput.
