this storage device is a great value for the price. I heard a lot of complaints on it. I have none so far. I got 259G. I am not a computer pro but I figured it out. I don't need the lock so I formatted to ntsc. I ran into problems when it kept telling me the stuff I downloaded was error or corrupted. I copied 13G from my 16G cruzer switch. that worked fine. I tried to store a copy of win10. it took 6 hours and then it was error or corrupted again and could not access it. my system recognized this and sent me to scan disk. I did the scan and cleaned and took care of the errors. you cannot be impatient, just let it run. for the formatting. I am using it for back-up. seems to work fine now and still have 229G left. I do keep cd backups. I have my cruzer and this new one. when it comes to computers, you have to play musical chairs. since this a electronic device I would suggest you also put backups or a image on a cd just in case. I guess speed depends on your system. I am running a older HP desktop. windows 10. if you have a loaded computer I would say buy 2 or 3 these and make 2 or 3 copies of your system. if 1 goes bad you still have spares. I paid about $16.00 for a 16G cruzer switch. this blue is a bargain. I am ordering another from the same seller. I stay with good sellers. there has been a few bad items but for most of it the products are great. I probably have 100 bids right now. I stay with the same sellers. I will let you know how fast it is next time i load it. got my second blue today and formatting it now to ntsc. when I pluged it in it said only 249G. i will follow up after format. still a great item for the price. I think all of you complaning just don't know what you are doing or its your computer. it may be slow so do your downloads before you go to bed or set a schedule and in the morning its ready. it does work on win10 and on my hpdc5700. quit complaing on this item. I like the blinking light so you know it is working. if it stops you have to check the download. look for hidden windows. quick format to ntsc goes quick. regular format I would do overnight and use ntsc format. formatted it and still have 249G on the new 1. that's fine with me. that's all folks. good luckRead full review

This flash drive reports to the Operating System that it is 256 GB, however as you save data and the used space approaches 16GB, it begins to corrupt files making them unrecoverable. When tested using a program designed to check a flash drive's real capacity by writing files and reading back the saved files, the results indicate that this drive is really only approximately 16GB that has been hacked to report the 256GB. Once this drive exceeded 14GB, all files saved beyond that point were unrecoverable. Beware of cheap high capacity flash drives on eBay. Many are specifically manufactured to work for a while until its real capacity is exceeded. Name brand drives may be less likely to be fakes but they also can be counterfeit. The only way to be sure of a flash drive's actual capacity is to test it by writing files to its full capacity and reading back and verifying the saved files. I recommend that you always test the actual capacity of any flash drive before saving valuable data to it and assume that all is well. Just because a flash drive reports to the OS that its capacity is a certain size, that can be faked. You won't know that you have a fake drive until you actually have used it for a while and discover that your files are damaged. By that time it is too late to return and your files will be permanently lost. Buyer beware.Read full review

I was looking for a nice, low cost backup storage. This thumb drive at under $15 stores 256 GB and fits the bill! I have used it for a few weeks and I am happy with this drive. The only minus: transfer/backup of large files (or large volume of data) takes time.

I have purchased three of these, and my first use of it was satisfactory. A very good value for the money. However, I trusted one of these flash drives for valuable data that was sent by mail and the data was lost. I now have no confidence that the flash drives for important data.

I bought 3 of these flash drives and all 3 did not work correctly. One was completely broken and could not be written to at all. The other 2 appeared to be working just fine but then I noticed that when I put more than 16 gb of data on the drive it was not readable, including several MP4 movies I had put on there to take with me to a friends house. The vendor was very polite and gave me a complete refund.
