Question: I have no understanding of a memory card reader. I want to download music from my iTunes playlists to an  SDHC card. Can I do this with a card reader?
Document: Transfer files has never been so easy until I bought this memory card reader. I download music, pictures,  movies on my phone then take my memory card out and put the memory card in the the reader and plug it up to my computer or ps3 and it's that simple. There's no programs or extra process you have to go thru, once you put the memory card in the reader and plug it up to whatever you want to transfer files to it's ready to go.
I had originally purchased this Plugable USB Flash Memory Card Reader (the Gizmo) to use to download music files to a Micro SD card that installs into Hubby's Bluetooth headset. The Gizmo worked great, just as advertised. I thought that would be the only time I would be using the Gizmo, but then I had trouble uploading pictures from my camera to the computer. Ugh! Then, I remembered the Gizmo!
I needed a USB 3.0 card reader and I didn't want it to be one of those direct plug-in types. This one had a nice design and gave me the SD and Micro-SD slots I wanted without all the other slots I don't need. I had no need for the Memory Stick slot, but I'll put up with it until I can put a piece of tape over it.
I have an unreliable card reader that is built into my computer. I bought this because I needed to actually be able to quickly download my photos. Unlike my multitask card reader, this card reader was immediately recognized by my computer and functioned as advertised. Not sure what else to say other than to state that when I build my next computer, I won't be buying a card reader because I already have one...it's the Plugable SuperSpeed USB 3.0 Flash Memory Card Read.
My previous IOGear multi-card reader died on me after a couple of years of service, so after reading the good reviews here on Amazon I bought this one. So far it has done a nice job of reading and writing my 16 GB SDHC (generic) and 64 GB SDXC (Sony) cards. It also reads my old Sony Memory Stick.
My computer wasn't reading the newest SDHC/SDXC memory cards I was using in my dSLR, but this little guy reads them all. No extra drivers to worry about, nice compact design, and faster transfer speeds than my internal card reader. Best of all it is so small it fits right in the camera bag without taking up much space. Excellent product.
I have an old card reader but it doesn't read the new SDHC memory cards. I ordered this card reader to replace the old reader. This is perfect. It's small, inexpensive and does exactly what I wanted it to do without any complications. I was able put the memory card into it, plug it into a USB port and my pictures showed up almost instantly. As I said just exactly what I wanted. It's perfect.
Had to break down and buy a new memory card reader when a 3-year-old one wouldn't recognize the 16gb SDHC card my camera was using. This one read that card with no problems. Its lively green color really has helped when I would go looking for it.True to its Plugable name, it has plug and played very nicely with both Knoppix and Ubuntu (Debian Linux based operation systems).
If your desktop or notebook computer does not have a memory card reader, you will not find a more convenient one than this. This little USB 2.0 card reader is nicely made, inexpensive, and SMALL. It handles SD, SDHC, Micro SD and MS/Pro cards (I am not familiar with that one) which means that it will handle any card I own excepting CF cards. This unit is small enough to slip into a computer case or whatnot, and works well.
been looking for this exact memory card reader, works as advertised, no software to download, compatible with almost all systems. Good stuff
Answer: If your computer has a USB 2.0 or 3.0 access, and iTunes allows it, yes. I don't know anything about iTunes. You stick the SDHC card in one of the slots on the reader. Each slot is for a different type of memory. A card reader allows you to transfer or access files either from computer to card, or from card to computer. I can stick the card in the reader then drag and drop MP3 files from my computer onto the drive the reader is inserted. The MP3 will then show up on that card. I can also drag songs from the card onto my computer. A memory card reader doesn't read a card by itself. It just allows you to transfer data/files between the card and the computer in either direction.
