Question on data storage

[Rhino79]

When I manually browse the files in My Files, I see that the directory is named /sdcard. But I don't have an SD card in my phone. Does the phone come with one as a "hard drive" so to speak? And if I upgrade its storage with an SD card, will I be replacing one?

Also, under Settings-Storage, it lists "USB Storage" and its values. What does this refer to?

Thanks.

I'm not totally sure but I think that internal memory is listed as /sdcard and if you have a memory card that is listed as /external_sd. I have no clue about the usb storage.

Why this is... I do not know.

/sdcard is a default "mount point" that points to an area of "internal" storage that as a user you can manipulate. Think of it as "My Documents". The rest of the internal storage is in different mount points that you can't get to - that helps prevent you from bricking your phone.

/sdcard/external_sd gets created when you insert an SD card into the slot in the phone.

/sdcard/usbStorage is empty unless you attach a USB storage device. When you do that, it gets mounted to the /sdcard/usbStorage "mount point"

These are, of course, my understandings only. Others may have different (more technically accurate) opinions.

Your right on Mike. Its also listed in the Sticky "25 Reasons to buy a Galaxy S2".
