The mini SD card was released in 2003 and is often used in mobile devices. The mini SD is 20mm wide by 21.5mm long by 1.4mm thick, and weighs about one gram. It has 11 pins and no write protection.

While card readers are useful for photographers, videographers, and other creatives, it’s unclear why the dock offers two SD slots alongside the MicroSD reader. The RayCue dock is priced at $99.

The readers range from $79.99 for the multi-card reader with SD / microSD and CF to $199.99 for the Red Mini-Mag reader (Red’s own reader is around the same price).
