# Partition

The partition layout is a bit different on the first part. We prefere GPT every time where is possible. With SoCs they don't support GPT, we can use the hyprid GPT. More about this on [development](development.mnd) documentation.

The system is designed to have less as possible writes on the system. Which means we have basicly just writes on the OTA update and pretty small (5-6 times per week) on the overlay part. The Data partition have real I/O which is possible to offload into a different drive.

The data partation is the only partition with real I/O. It will be expanded automatic on boot time to the full size of the disk.
The data partition is the only partition with real I/O. It will be expanded automatic on boot time to the full size of the disk.

This partition can be offloaded to a different drive with the utility:

```sh
$ datactl move /dev/xxx
```

On next boot, the partition will be moved to the new drive. The drive need to be bigger as the old one and we own the full new drive.
