Adding a third Physical Partition

[biswaKL]

Right now, by default NOOBS has 2 physical partitions, RECOVERY, and Root, where the root part is again divided into 3: Setting, boot, and root,
So I want to have a separate physical DATA partition for all the IO operations, how to create this during the installation.??

If you connect NOOBS to the internet you will have a wider choice of OSes to install. One of the choices is called Data Partition. If you select to install that in addition to your main OS you will have an additional 512MB partition as you want.

If you are using PINN you can go to http://pinn.mjh.net to customise the size of this partition, or (with noobs or pinn) you can download the data partition folder to a usb drive for a local install and you can set the required size yourself.

Just for your future reference, the RECOVERY partition is a PRIMARY partition. As are /dev/mmcblk0p2 and /dev/mmcblk0p3. There is a maximum of 4 primary partitions on a disk. To add more partitions, one of the primary partitions need to become an EXTENDED partition. This is what /dev/mmcblk0p4 is (what you called 'Root', but it is not actually labelled as anything). Inside the extended partition are LOGICAL partitions. You can have a lot of those. The SETTING, BOOT and ROOT partitions are all logical partitions (starting at /dev/mmcblk0p5) within the EXTENDED partition of /dev/mmcblk0p4.
