Data storage

Sony Ericsson P1 is divided into two parts:

A GSM phone part, having flash memory. This is very similar to a conventional mobile phone.

The RAM (Random Access Memory) is controlled by the Symbian OS operating system and is not used to store any user or program data. The RAM is totally re-initialized when Sony Ericsson P1 is started.

The available 256 MB flash memory is split into approx. 95 MB for operating purposes and up to approx. 160 MB for storage of user data, such as, audio files, pictures, documents, additional languages and settings such as the active theme. Flash memory retains data even with no power applied. Unlike some PDA devices, Sony Ericsson P1 does not require a small 'memory backup'

battery. Data stored on Sony Ericsson P1 is therefore not subject to loss due to such a battery running down.

The first memory bank is used like a ROM. It stores the Symbian (UIQ) operating system, the built-in applications and some essential multimedia information like a default ringtone. It also stores the language files for UK English which is the default language of the Standard Sony Ericsson P1. Chinese models also have Chinese stored on the ROM.

Note: The extensive MMI of Sony Ericsson P1 means that it is impractical to hold many languages inside the phone, as is the case for some other models.

Part of the flash memory provides a 'C:' drive of up to approx. 160 MB capacity. This behaves just like a normal disk drive. The folders can be viewed and managed from the File manager application or from a connected PC.

User storage

The user storage space (C: drive) is shared across applications without any imposed restrictions, apart from the whole space becoming full.

Unlike a PC, the user does not need to be aware of the underlying filing system. Applications will always store information automatically in the appropriate folder, simplifying the management of data. Third party applications may implement more complex file management solutions where required.

Additional storage space is available by using memory cards. Sony Ericsson P1 is delivered with a 512 MB Memory Stick Micro™ (M2™) memory card. Memory cards of up to 4 GB capacity are supported. Any number of memory cards may be used for storage. See “Memory Stick Micro™ (M2™)” on page 37 for more information on how to use memory cards when exchanging data with other devices.

Depending on the application, data can be beamed, mailed, uploaded to the Web, transferred to a PC or moved to a memory card in order to archive and create free user space on Sony Ericsson P1. See “Synchronization and data transfer” on page 42.

User storage configuration in the new Sony Ericsson P1

Applications and information are placed in the internal storage of Sony Ericsson P1 in the factory. This provides sample demonstration, educational, multimedia and fun content so that Sony Ericsson P1 can be used directly out of the box. Much of this can be deleted by the user in order to make the space available for personal use.
