Write/Save file to iPhone

Question

Hello all, I am currently saving images to the iphone's local space whenever I finish loading them. I was wondering if I need a separate thread to do that. I.e

The iphone can be requesting multiple images at the same time and when they are loaded, I call the save to HD method.

Since there are a lot of save to HD method being called at the same time, does anyone think I need a separate thread for each save to hd calls or somekind of queue that stacks the objects before being processed ?

Thanks.

There is NSOperationQueue class which allows you to run operations in background: http://developer.apple.com/library/ios/#documentation/Cocoa/Reference/NSOperationQueue_class/Reference/Reference.html
