Review on 📸 Delkin USB 3.0 Dual Slot SD & microSD Travel Reader - Review, Features, and Compatibility by David Garnic

Delkin Travel Reader DDREADER-46 has SD and microSD card slots. On Win 8.1, only one card could be read at a time, depending on which card was inserted first. It says "UHS-I and UHS-II Compatible" on the box, but it doesn't have UHS-II pins for a faster interface. It is also speculated to be "10x faster than USB 2.0 readers, up to 500MB/s". While USB 3.0 can be that fast, the reader is capped at a theoretical maximum UHS-I speed of 104MB/s, which is only about three times faster than USB 2.0 readers, which are typically capped at around 35MB/s. Protective caps on both ends cover the USB and card slots, and you can store SD and microSD cards in the cover reader. The caps do not nest and there is no way to store them when the reader is in use. There's an LED that lights up when a card is present and flashes when it's accessed, but it's not very visible through the translucent casing. The reader is just over 3 inches long with caps or 2 5/8 without. It's just over 1 inch wide and about 1/2 inch thick. It seems longer than it should be and larger than similar readers like the Transcend RDF5. It's longer and thicker than the Kingston MobileLite G4, but not as wide. The Kingston reader supports the faster UHS-II interface for SD cards. Read and write speeds with UHS-I SD cards are good. I get 97.5MB/s sequential read and 91.2MB/s write with a SanDisk Extreme Pro 95MB/s UHS-I card. It only reads UHS-II cards in UHS-I mode and not faster than UHS-I cards. The Lexar 2000x UHS-II card achieved a read speed of 93.9 MB/s and a write speed of 92.1 MB/s in this reader. The Delkin reader comes with a 1-year limited warranty. No country of origin is listed on the device or packaging, but I'm assuming that like the other card readers, it's made in Taiwan, not in the US, where they assemble their memory cards.
