PI 2 Memory

Since the Pi 2 has an operating system, I presume it has some type of internal memory capacity. What is that capacity?

Also, if the internal memory is solely designated for the OS, is there a restriction on what OS can be used?

Lastly, given that it has an SD slot, and I see the news release on the Pi 2 suggests UP TO an 8 GB SD card or an external SD card reader for higher, is it suggested to us SD cards for memory vs External Hard Drives?

Thank you.

You really need to read the specs, but in short, the Pi2 has 1GB RAM, No on board flash storage. All storage is supplied by the SD card so that contains the OS, which can be any of the supported OS's (mostly Linux based). You can add extra drives via USB if you wish.

There is only a 8Kbytes bootrom to load bootcode.bin from the SD card and fallback to SPI/I2C/USB slave if there is a problem.

To add to that, the raspberry pi doesn't have a maximum SD card capacity. You just have to make sure it is formatted as FAT32, not the default of exFAT which takes effect on SD cards over 32 GB.

Only the boot partition should be formatted as FAT32.
But this is done automatically, when you install raspbian via Win32DiskImager for example.
Ne need to format it manually.
After the first start of rasbian your are asked to start raspi-config, there you can expand the root partition to max.

Yes, that is what I meant when installing NOOBS. Using an img will automatically change the partition table.
