Fbo Delivers Sustained Mobile Phone Performance Page

As a mobile device is used, files are constantly written, deleted, and modified. Over time, this leads to two types of fragmentation:

FBO is a feature introduced in the (Universal Flash Storage) standard to combat this aging effect. It functions through a specific host-device protocol: FBO Delivers Sustained Mobile Phone Performance

The host (phone's OS) identifies specific files or address ranges that are critical for performance. As a mobile device is used, files are

The host asks the storage device for the current physical fragmentation level of those files. As a mobile device is used

By physically reordering data into contiguous blocks, FBO can restore read speeds to "like-new" levels—for example, returning a degraded device to a 1900MB/s read speed. Market Implementation & Standards Implement File-Based optimization functionality - LWN.net
