Hi All, Lately, I've been been picking up free 8GB microSD cards, thanks to the=20 good folks at ebay. They come with an SD card adapter and a USB adapter,=20 so they can be used in any computer. To get yours, stop into ebay and search for "microSD". Don't worry about=20 the price, just buy the unit as you will be getting a refund later. All=20 the low priced unbranded units on ebay are not the capacity that the=20 seller claims. And, they are also not class ten speed rated, I get=20 transfer rates to and from a solid state drive between 1 and 2 MB per=20 second. The units that I've been testing are XC brand, any of these=20 units are fake. I'm sure there are other fakes on ebay, but those marked=20 'XC' are 100 percent bogus. Seethe picture of of of these units on ebay,=20 search for auction #272112104374. After you receive the item, tell the seller it is a fake, and they will=20 bend over backwards to refund you, hoping that you do not leave negative=20 feedback for them!!! So, the memory ends up being free. The 64GB units are all between 8 and 10 GB of actual memory, despite=20 what the seller claims. I have been using them in my smartphone because=20 I don't need larger capacity units. I've freed up two 32GB legitimately=20 rated cards so far. My daughter uses them in her portable mp3 player also. I've also used them to backup my data that I want archived. I have my=20 primary backup on a conventional usb hard drive, but I use the fake=20 microSD cards as a backup for my primary backup archives. Works for me!! Be aware that a directory of a full card shows the fake capacity, so=20 most think the card is legitimate if they just examine the directory=20 structure!!! To really test them, load the card with a few GB of data=20 files and then spot check the files to make sure they open and function=20 properly. I use mp3 music files for testing. If the spot check passes,=20 load up another 2GB of files and test them. At some point, one or more=20 of the files will be corrupted, you can't open an mp3 or text file etc.=20 When this happens, you know the actual capacity of the microSD card=20 under test. If you want to confirm that the files are corrupted, use any binary file=20 editor and look at the suspect files. The corrupted files will show no=20 file type indicator, at the beginning of the corrupted files. There will=20 be no ascii characters anywhere in a corrupted file. The corrupted file=20 will show all 00 or FF data from beginning to the end. It is extremely important to realize a fake 64GB microSD card will show=20 64GB of files that look legitimate if you just examine the directory of=20 the card. The only way to really know if a data file is legitimate is to=20 play or open the file, or look at suspect files with a binary file editor. If you can live with 8GB of memory, the fake microSD cards are a bargain:> Enjoy.
