Functional and colorful USB thumb drives in a useful capacity, and colorful selection. Quick check indicates they are full advertised capacity, less the storage required for for their exFAT partition which makes them compatible with Windows, Mac or Linux devices. Scan with McAfee indicates no viruses, which is always a good thing to check with ANY new USB devices. Shells are hard plastic which should retain color well. LED light in the "keychain slot" to show connection and read/write activity. That's a function you don't see on some major brands. That hard shell does have a design issue however. While it feels solid as you extend/retract the USB connection from the shell, it slides far too easily on insertion. It's practically a two hand job to plug it into a port - one to hold and align the device, and another to hold DOWN the top of the device. Otherwise, insertion attempts simply push the connector back into the shell.

I haven't had them long enough to tell you how they last after years of use, but they seem to be writing just a touch faster than my other flash devices on the same hub. Not absolutely sure that the sustained rates really work out consistently faster, but they sure seemed to be. The data read nicely and without any errors that I ever encountered. The devices get pretty hot if you write a lot of data to them, so keep that in mind. When reasonable, giving it time to cool after 10-20gb seems wise The sliding sleeves on the cases only help protect a little and are mostly a gimmick. Still, it's better than nothing, as long as it stays dry. Worse when water gets in there but it does make that a little less likely while the sleeve is covering the jack. Most of the colors look like children's toys. That actually could be desirable in some cases. The green is ugly, especially with the red LED lit. For my purposes, the important thing is that they can be easily distinguished and they handle that just fine. So, to summarize: they work better than expected for their primary purpose and have some design features that are helpful, albeit slightly. They aren't works of art but they are good data storage devices.

I recently needed to update my flash drives for storing documents and photos, and this set of five 64GB drives has been a pleasant surprise. They provide a total of 320GB storage capacity, which is quite impressive for the price. The drives are color-coded for easy identification and feature a retractable design that saves space when plugged into a port. I particularly appreciate their compatibility with different operating systems; they seamlessly transferred files between machines running different systems without any issues. Overall, these drives offer excellent value, functionality, and peace of mind for storing and transferring important data.

I did some testing and found these USB thumb drives perform pretty well for the price. The benchmark gives impressive numbers for sequential access but not very good for random access. An actual copy operation in Windows was able to sustain almost 25MB/s writes for large files (sequential access) but that slowed way down to a few MB/s for small files (random access). I got similar results when reading from the thumb drive. Around 100MB/s for large files but very slow (often <1MB/s) for small files. These will be best for moving large files like video unless you are not in a hurry.

I was really needing some new flash drivers. I have a bunch of documents and photos on my computer. I got this set last week and I'm very pleased. They each hold 64GB of data so with 5 of them go get 320GB of storage. That's pretty cool for the price. I like that they all have a different color and they have a loop so you can put them on a key chain or lanyard. They retract very smoothly. I am very happy with this flash drive set and have no complaints

Getting a 5 pack of 64 gb flash drives is a really good deal. The flash drives come in 5 different colors so you could keep them all separated for different things. The usb part slides up out of the case and retracts back in when you want to store it. It writes to the drives really quickly and works just as expected. There's a loop on top that you could add a lanyard or keyring to it to take on the go. Definitely would recommend.

These little flash drives seem like a good, economical way to store info for backup. With 5 memory sticks at 64 gb each thats 320 gb of storage which is quite a bit. Considering the price, this seems like a good deal. Its a nice touch also that they are retractable and don't take up a huge amount of real estate at the docking port, which is a problem i have with other flash drives in that the other ones are wider. I tested one and it seemed to work just fine. They are also color coded, so, easy to distinguish one from the other on sight.

I run a home based business. Due to security concerns we don't allow our production machines to be networked or connected to the internet. As a result we move the images to be printed from the prep computer to the production machines via Flash Drives. I tried this out for a Photo ID order we were running and the drive was recognized and installed easily on both machines. The files wrote and transferred without issue. The two machines were using different operating systems, so I felt it was a plus that it worked with both. So far, so good.

This pack of five 64GB thumb drives represents a good way to have several general purpose flash drives available for occasional use transferring large files or folders. They are not terribly fast but they are faster than most inexpensive thumb drives. Read speeds for 1GB sequential files ranged from 98 MB/s to 117 MB/s in my testing. Write speeds were 13 to 36 MB/s. So if you fill one of these with data, you might want to go have a cup of coffee while it writes. By the way, one drive had the low data for both write speed and read speed. The others were all grouped near the top end of the range.

As much as I've tried to use sharpies on these kind of things in the past and it just rubs off, this is a great way to keep them organized. Another big plus is the price for 5 drives of 64GB I think is really reasonable. I highly recommend.
