Buy Vansuny 128GB USB C Memory Stick USB 3.2 Gen 1 Type C Flash Drive Ultra High Speed USB C Stick OTG Dual Pen Drive, Up to 400MB/s Read and Write, Black at desertcart UK. Review: Awesome write speeds, literally 10x faster than all the other junk dual-USB sticks - I spent hours trying to find a dual-port USB flash drive that didn't have terrible write speeds, and almost gave up. All the others, including big names like SanDisk, are pathetic and none have write speeds greater than 20MB/s (both from personal experience, and from seeing others' screenshots of speed tests in the reviews). Saw the bold claims on this one and decided to try, and it did not disappoint. All of the following tests were done using the USB-C end: On a 5GB sequential write speed test, this one starts at write speeds of 300MB/s for the first 3GB, and then slows to 170MB/s at the end of the 5GB. This is very good. (See attached screenshot) For a real-life test with hundreds of files: writing a 13GB folder containing 830 songs, it took 155 seconds, so average of 84MB/s, which is also good. So this drive is 5-10x faster than anything else I could find on the market, so highly recommend. Oh and read speeds were consistent at 330MB/s which is great, but it's write speeds that usually let a product down so no surprises there. Oh and build feels solid and I like the retractable ends. Can't comment on durability as have only owned for long enough to run these tests Review: Very fast for data transfer with my iMac - This stick is super fast at copying to and from a Mac. I have hundreds of photos airdropped to my Mac which I like to back up regularly so I can also have them stored on my hubby's Microsoft PC. Many sticks seem much slower to copy when the files are all in folders but not this one. I haven't used it to copy and paste with a phone because when it came it had the wrong end for my iPhone so I don't know how well it works for that, but I can highly recommend it for data transfer speed to and from a Mac ## Features - 【2 in 1 Dual Flash Drive】The usb memory stick with the USB 3.2 Gen 1 and Type-C interface can easily transfer files and data between smartphone, tablet, and PC, instead of Using WiFi and Cloud Services.
