MOSDART 64GB USB Flash Drive 5 Pack, 64 GB Multicolor Multipack USB2.0 Thumb Drives, Swivel Design with LED Light, exFAT Jump Drive Memory Stick for Computers, Data Storage

Differently colored drives, with caps that click-on; providing superior protection of the business end. Haven’t used all five yet, so I can’t comment on longevity.

I bought them to have my library of music and videos to use on my tv and they are perfect for their speed and storage.

NO issues. used immediately, on 3 different tablets, and 5 different laptops. Storage is as expected, products were great quality. Havent seen anything that would cause me to worry so far. As other reviews had said, the packaging was great as well. Could just throw 5 drives in a zip lock bag or a small shipping box, but they came neatly in a small box, very clean, very neat. Recommended.

These were great at first, beautifully and professionally packaged and I used them to back up videos, pictures, pdfs, stuff like that of which I have a lot, OK, too much. But tother day I went to add some vids to the video 32Gb and it failed. Fortunately I had a back-up so I did not lose my data. The next day, a second one failed. I tried everything to use it, and then to format it after Microsoft swore it scanned and repaired it. No. Garbage. So, I dont think thats a very long life and I probably will never buy them again and will have to review my files to make sure the other 3 have not failed.

This review is for the mosDART 16GB USB 2.0 Flash Drive, 3 Pieces. I have noticed a growing trend in USB thumb drives and memory sticks. It seems that one is hard pressed to find the actual memory size one is looking for, because, as in this case, a device that is sold as a 16GB flash drive is actually only 14.8GB of usable storage. (I recently purchased a thumb drive that was allegedly 64GB which in actuality was only 57.7GB of usable space.) These numbers dont add up no matter how you calculate it. While it is true that some space is required for the File Allocation Table, it should not consume 1.2GB of space. In fact, Windows reports that only 8KB were used to hold the format information, which translates to 8,192 bytes. A far cry from the missing 1.2GB of space. 16GB is equal to 17,179,869,184 bytes, yet the mosDART 16GB USB 2.0 Flash drive only has a capacity of 15,922,782,208 bytes, or 14.8GB. Even if one uses 1000 instead of 1024 to calculate the amount of storage, it still does not come close to being the capacity listed in the description. Most disappointing.

I was pleasantly surprised at the low cost (especially with Amazon Prime free shipping) for three 16GB flash drives. These are high quality drives built from high quality components -- see the earlier 5-star review from M Reno for more information. My only slight disappointment is that the pivoting clip does turn freely the full 360 degrees around the drive and does not lock in place in a closed position that would help protect the USB plug from damage. Given that it is also not tight-fitting to the surface of the flash drive, the pivoting clip is not designed to keep pocket or purse lint from getting into the USB plug. If it gets in your way, you can easily pop the pivoting clip off and discard it. The pivot where it fits onto the body of the flash drive still makes a handy grip for easily inserting and removing the drive. Now that there are so many more uses for flash drives including bootable flash drives that operate as recovery drives, it is great to have inexpensive but high capacity drives available.

To rec, my flava tv show.

I returned the 16GB mosDart USB drives since one memory-stick failed or was defective. Sadly, I found out after a couple of days of work that I lost because the data I had stored there was not accessible.the UBS could not be read and asked “if I want it to initialize it.” Of course that meant erase everything I had stored in it. I retried it again and again, even after I had powered off my computer, re-starting it and I got the same result. I went to check if I could read it in my apple laptop, got the same message, check it in a Toshiba laptop same thing. Tried it in my husbands Apple Tower and also got the same result. In 4 computers your memory-stick could not be read. Accepting to the idea that if I initialize the USB-stick would erase everything, I clicked to initialize it. Now, I got another message saying that the “initializing had FAILED.” In the many years I have been using floopy drives, CDs, memory-stick, flash cards etc. , yes, I may have had maybe a couple of bad floppy drives, even maybe a couple of CD disks. But this is the first time I had a defective memory-stick. Even the free memory-stick we get in conferences have worked fine for us. As you can surely appreciate, I did not want to experiment using the other drives from the package. Maybe it was a “bad-batch.” I purchased your memory-stick because they were less expensive than other name-brands (Patriot, SanDisk etc.). I learned that I better pay more for those name-brands than to have the uncertainty that if, I use the others, they may fail as well. I am working on a deadline with a publisher. How am I going to recover the loss of 2 days of work? after 2-3 days I returned the package with all the drives. I marked BAD or Defective over the bad drive. In addition I included a letter explaining the problem. Hopefully the seller reads it and makes sure that there are no other bad drives in their inventory.

I bought the 32gb with 3.0 usb and the data transfer is fast, a great back up flash drive for my files.

This is the second time I have ordered this product. I was satisfied the first time and this time is absolutely no different. If you need a product that does the job for a great price this is one of the best. The shipping is so quick. You wont be disappointed!
