multi card readers

I have an old SanDisk multi card reader that may be going down. Question, is a 3.0 compatible with 2.0 also?

If you buy a multi reader in USB3.0, one that plugs into a USB2.0, then yes, they are backward compatible. Though it will only be USB2.0 speeds.

Yes, USB 3.0 is backwards compatible with USB 2.0. It will work fine, you just won't get 3.0 speed, that's all.

Thank you both kindly! Currently my computer only supports 2.0; but I thought since I was going to buy a new card reader it would be nice to get a 3.0 for use with a future computer; but would still work with my present one.

Thanks again, I appreciate it!

Quite often 3.0 reader is faster (due to better electronics inside the reader) even in 2.0 socket.
Old 2.0 readers may not recognize SDXC cards (64GB+).
There is a very affordable Transcend usb 3.0 card reader on Amazon, works flawlessly with my SDXC cards (128GB).
If you have K-3 body, you may want another Transcend reader set (kit) with usb/microusb 3.0 cable, at microusb end compatible with K-3 body microusb socket.

Good information, thanks! I don't have a K3, however. Right now, only 2 K10D's. Seriously thinking of getting a K5IIs.

I have a couple of the Transcend 3.0 USB Card Readers. They're the size of a thumb drive. I also have the Lexar Multi Card reader. The little Transcend card reader is much more convenient.

The size really isn't important, as I have it on my desk, connected to the computer.

I have a bunch of these things in a junk box. They work a couple of times then don't. All the brands.

I will spend money for a reliable card reader, USB 3. What should I buy?

The Lexar was recommended to me by a local photojournalist. He said pretty much everyone he knows uses one to get their CF cards onto laptops, tablets, and desktops in the office. Apparently, they don't end up in the junk bin. So far, mine hasn't quit after 18 months of occasional, dusty use (it's for my Sigma SD1 CF cards - my iMac has a built-in SD slot).

PCI-E slot? If so, you can get a PCI-E card that will give you USB 3.0.

An example:
SYBA Model SD-PEX20139 PCI Express to USB Card Add-On Card - Newegg.com

The one I linked to has the 19-pin header so you can add USB 3.0 ports to the front of your PC if your case allows for it.

Sorry, I don't know what slot my computer has. I know very little about computers; self taught, and my teacher was a dummy in this field.

I've spent money on card-readers... they still go out, especially the type that you mount into a disk-bay. My best success has actually been from little thumb-drive form drives that work with just one or two card types. My recent selection are the Transcend ones mentioned earlier. They are the fastest readers I've had, even compared to my previous USB 3 reader, and they are cheap. I bought a few of them. I keep one always with my camera bag, one always in my home desk (for my computer), and a last one floats around a bit (mostly at work or with my laptop).

I sometimes think the multi-card (1 size fits all) readers are biting off more than they can chew by trying to work with every card type in the world. I replaced my last built in card-reader with a USB 3 header instead. It provides a lot more benefit than I expected in addition to the transcend card readers I have.
