10 Pack 8GB USB 2.0 Flash Drive Memory Stick, Vuefamy Swivel Thumb Drives Bulk for Data Storage with Lanyards and Removable Labels (8GB 10 Pack, Black)

...only 7 of the ten worked. The other three failed to format correctly and became useless. Other than that the ones that worked did what they were supposed to do.

This 10 pack of thumb drives is a great value for backing up discrete data chunks for portability and archive purposes. I use them to back up completed-job folders with large graphics files that I may have to access in the future but don’t want left cluttering up my system or the cloud. The included labels help me keep them organized.

This is your basic, unbranded USB 3.0 flash drive. It came with a little lanyard, and already formatted in exFAT, though I tested it with FakeFlashTest and reformatted back to exFAT. It tested at an actual capacity of 117.1GB, which is definitely in the right ballpark for a 128GB drive. However, even just testing the capacity seemed to be going a bit slowly, so I also checked the speed. Using CrystalDiskMark, I measured sequential read and write speeds of 120MB/s and 70 MB/s, respectively. That’s generally ok, and speedy enough for transferring very large files to/from this drive. However, if you have lots of small files to move, it’s not so good. The Random read and write were only around 5 MB/s and 0.8 MB/s, respectively. This is actually a pretty slow random write speed and reveals that this is a fairly low-quality flash memory chip, and the flash controller needs to write at a very slow rate to avoid errors while writing multiple small files or multiple random write locations. So, this is a fairly low-quality drive, and will frustrate you if you are transferring thousands of pictures or other large sets of small files (that would take hours). However, if you just plan to sneakernet a large ISO file around once in a while, this drive should be just fine. Just to verify this, I transferred a real, single 7.67GB ISO file to the drive. It took exactly 2 minutes, and wrote at an average speed of 64MB/s (always between about 62 and 65, so fairly constant speed). For the file size, this was fast enough not to cause frustration, so the drive is certainly usable for these situations. I certainly wouldn’t rely on it for long term archival storage of important files, but it should be fine to shuttle large stuff back and forth. Personally, I wouldn’t mind buying this drive, even with these limitations, if it were much cheaper than some of the name brand alternatives. Although it is somewhat less expensive, it’s not enough less expensive to justify the performance, so I’m not sure I’d call this a great “value” unless you really need to save the few extra bucks. Final Rating: 3 stars. I’m knocking off two stars for the extremely slow random write speed. But it does at least work, and sequential read/write is in the ballpark of USB 3.0 speeds (lower end, though), and the 128GB size was legitimate (117GB actual).

This drive shows 125,822,959,616 bytes free on my Windows PC. The performance seems fine and it works as expected. It comes with a wrist strap that is meant to be connected to a little handle on the top of the drive, but it is very hard to thread the strap through it since it is so small. I got it after a few tries, but really, who needs a wrist strap for their thumb drive? Overall a good drive with large capacity for the price.

This 5 Pack 64GB Flash Drive USB 3.0 Thumb Drive High Speed Swivel Memory Stick Jump Drive with LED Indicator/Lanyard/Label for Storage and Backup is an awesome deal. At the time of writing this review, this set was $27.99. This is very reasonable for 5 USB sticks. I gave 4 to my kids and they use them for school. They haven’t encountered any issues and they have been using them for several months.

Perfect! Checked one of the five by copying my music collection to it consisting of about 16GB. Took about 10 minutes on my old 2.0 USB port. Im sure it would have completed much faster on a USB 3.0 port. Copy was checked by playing several music selections from the flash drive. As I said, Perfect. The included lanyards are a bonus.

I like the included labels to put on the flash drives for identification. Also, 5-straps are included to attach to the drive. I like that the drives have a little light in the back that flashes during activity. I tested the flash drives by transferring some files from my computer to the flash drives. These flash drives are very responsive and fast. Excellent!

Picked one at random to test. Used Etcher to burn a linux iso to it. Write speed was good and stable. Excellent for the price. The linux booted fine from it.

These drives were perfect for me to put music on for the members of my group. A good hyoid size if you only need to transfer a small amount off data.

Using Windows 10 Photo documentation for my work is a constant. Dumping my pics (often 100+ at a time) onto a flash drive. Needs to go fast and smooth, as well as whoever is opening them and on what. Holly crap ! $4.40 apiece they work flawlessly and look very nice. A+
