If fragmentation is high, the host instructs the device to perform physical defragmentation .
As a mobile device is used, files are constantly written, deleted, and modified. Over time, this leads to two types of fragmentation: FBO Delivers Sustained Mobile Phone Performance
This fragmentation forces the storage controller to perform multiple "seeks" to read a single file, significantly slowing down app launches and system responsiveness. If fragmentation is high, the host instructs the
This report examines , a storage technology standardized by JEDEC to ensure mobile phones maintain high speeds throughout their lifespan . While new smartphones often feel fast, performance typically degrades over time as data becomes fragmented; FBO is designed to solve this specific "lagging" problem. The Core Problem: File Fragmentation This report examines , a storage technology standardized
Parts of a file are scattered across different logical addresses.
The host asks the storage device for the current physical fragmentation level of those files.
FBO is a feature introduced in the (Universal Flash Storage) standard to combat this aging effect. It functions through a specific host-device protocol:
