Can I store my itunes music library on an SD Card?

I get serious performance issues when running iTunes with the library on an SD card. I think the problem is that SD cards are designed for sequential reads and writes (as in a media stream from a video camera for example) and have problem coping with the more or less random reads that happen when loading album artwork, for example.

I now have the iTunes library on my primary disk and the iTunes Media folder on an SD card, which is working much better. In Preferences under "Advanced" you can set the iTunes Media folder location. Then you can consolidate the library to copy all media to that folder.

iTunes can put the media library anywhere, boot disk, secondary disk, network box etc

all it needs is a drive letter

Launch iTunes with the Shift key held down and create or choose a library on the card. It needs to have enough room to store the library, and if it's transported between computers, any rented movies in the library will only play on the computer they were downloaded to.

Yes, you can store your iTunes library on any accessible drive. The best approach is to have your complete library (database & associated files as well as media) on the same drive - see turingtest2's user tip on Make a split library portable.

Two points to note:

• SD cards are limited in size, so you'll not have a lot of space for your library to grow
• SD cards may have some issues with reliability / longevity, so be doubly sure to create and maintain a backup to external media and/or the cloud.

One of the four systems that I routinely run iTunes on (an HP Stream 7 tablet running Windows 10) uses a 64GB SD card for a small, local library.
