Regular readers will recall that i rip my DVDs so that I can put them on these cards and watch them on my tablet in more relaxed circumstances. An 8G card can, if I'm not using it for anything else (as in dedicated swap-out/swap-in mode) I can fit 4, maybe 5, and possible a Youtube excerpt on the 8G cards. But copying from the PC to the card of even a couple is an over-night project.
Something is wrong, then. They should write at about 10 Mbyte/second.
This is a hardware issue, those adapters may be OK for use in a camera and retain speed, but the USB i/f is limiting. And these chaper cards are not blazingly fast. Adequate for extending the phone's memory and for movies and storing text, but not recording streaming video.
USB should read/write at 20 MByte/second. If they go at 2MB/S, you have the wrong adaptor: USB 1, not USB 2. It happened to me recently. I noticed that my card reader, cheap, was very slow. I replaced it with a good one from Trascend and the speed increased ten times. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
