Solved What is the difference between card readers? Tags: USB Card Reader SD Card Reader Memory Card Components Last response: June 18, 2014 8:43 PM in Components Share CristianDortona June 18, 2014 8:05:09 PM As I was looking for a card reader, I've figured out that there are 3.5 card readers and 5.25 card readers, but what's the difference between them? More about : difference card readers Reply to CristianDortona cin19 June 18, 2014 8:40:13 PM That format (3.5" or 5.25" ) don't matter, you want to pay attention on the connector, is it USB2.0 or USB3.0? because usb3.0 is faster than the USB2.0, but you may pay more $$ for it.

Reply to cin19 m 0 l Best solution Cons29 June 18, 2014 8:43:20 PM disregarding the specs (just sticking with your question), the difference would be where the card reader would be installed (or where it would fit) 3.5 is the floppy disk slot, the 5.25 is the optical drive slot. Do note that some 5.25 bays have adapters to fit 3.5 also. hth Reply to Cons29 Share Ask the community Post an answer Related resources SolvedWhat's the difference between dedicated / Pci Lan card & on board / built in one Forum SolvedWhat's the Difference between a low & high end card???
