UIQ 3 devices incorporate several memory types serving different purposes.
1. ROM Drive Z:
The Z: drive is called ROM drive. It contains the operating system - the Symbian OS 9.x / UIQ 3 software. This memory is based on Flash chip and is read only. Users cannot modify its contents. This memory can only be erased and re-written during the firmware update process either by authorized service centres or using the Sony Ericsson Update Service.
2. User storage disk C:
Disk C: is like hard disk in your desktop computer. You can use it to store different kinds of files and install 3rd party applications. The system uses it to store its settings and databases (like Contacts database or Calendar database). You can freely modify its contents, but you should avoid modifying the System folder, which contains system data and settings required for the device to boot and work. The size of this disk available for the user in UIQ 3 smartphones is about 80 MB. Disk C: uses Flash memory, which means that its contents are fully secure even if you remove the battery as Flash chips preserve their contents without any current supplied.
3. Storage memory card D:
Disk D: is the Memory stick Duo (or Memory Stick Micro M2 in M600) memory card. Basically, it serves as an expansion of the internal storage memory (disk C:). You can use it to install third party applications and store different kinds of files and documents.
4. Operating memory - RAM
This is a separate memory that works exactly the same way as RAM memory in your PC. You can't install any applications or data in it. This memory is used for execution of the operating system and applications. P990, M600 and W950 contain 64 MB RAM.
