MFi Certified 128GB Photo Stick for iPhone Flash Drive,USB Memory Stick Thumb Drives High Speed USB Stick External Storage Compatible with iPhone/iPad/iPod/PC

100% cumple con su función. El problema es cuando lo quieres usar en más de 1 iPhone, porque cuando copias de más de un iPhone, en la Mac solo se ven los archivos de uno. Pero tiene solución. La calidad es media, al 2do día se me rompió una liga que únela tapa con la usb (fue descuido mío). Sirve su función solo que tiene su chiste usarla.

I ran five tests with this USB Flash Drive. All tests were done on my computer which has a Ryzen 9 7900X CPU mounted on an ASUS ProArt X670E-Creator WiFi motherboard. Test 1: Capacity As you can see in the photos the before and after shots show how much data I put onto this drive. I filled it up with 127,946,063,872 bytes of data and still had 1.92 Gb free. So, the capacity is accurate. Test 2: Connected via USB 3.1 HUB A sustained data write speed of 36 MB per second. Test 3: Connected via USB 3.2 A sustained data write speed of 217 MB per second. Test 4: Connected via USB 4 A sustained data write speed of 215 MB per second. Test 5: Connected via USB 4. Read from and write back to the Flash drive (File copy onto itself) A sustained data read/write speed of 113MB per second. The description for this USB Flash Drive states a theoretical transmission speed of 5.0 Gb/s. Keep in mind this is in a perfect world scenario and not likely in the real world. Just a selling point gimmick. The description also states that this Flash Drive has a maximum read speed of 80MB/s and what they call a "Perfect" write speed of 50 MB/s. I'm not sure what they mean by "perfect" but as you can see in the photos, I blew that 50MB/s out of the water reaching 217MB/s. All of these tests were done back-to-back. Writing that much data made this little Flash Drive very hot. In conclusion, this USB Flash Drive lives up to and exceeds expectations. I give it 5 out of 5 stars.

Good product that works well and a good price

Awesome! I rarely give full marks, but this product is really good. I want to share photos and this product helped me a lot. First of all, its packaging is very good, very strong. The quality is very good. It is very convenient to carry, and more importantly, the operation is simple, whether it is on a mobile phone or a computer, it can be connected quickly, and the transmission speed is super fast! Thanks to this product that I can keep all of my important memory in the past. It is with reasonable price. Fastastic!

Looks good as it claims to be with adaptor and lanyard. Easy access to phone or P.C. I have not yet downloaded anything, so that part remains to be seen. I am happy with it and fully recommend this product.
