Fbo Delivers Sustained Mobile — Phone Performance

If fragmentation is high, the host instructs the device to perform physical defragmentation .

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.

Even if data appears contiguous to the software, the physical flash memory (NAND) may store it in non-contiguous locations due to background tasks like garbage collection . If fragmentation is high, the host instructs the

Parts of a file are scattered across different logical addresses. If fragmentation is high
