sector diskの例文
- While the design of the FAT file system does not cause any organizational overhead in disk structures or reduce the amount of free storage space with increased amounts of fragmentation, as it occurs with external fragmentation, the time required to read and write fragmented files will increase as the operating system will have to follow the cluster chains in the FAT ( with parts having to be loaded into memory first in particular on large volumes ) and read the corresponding data physically scattered over the whole medium reducing chances for the low-level block device driver to perform multi-sector disk I / O or initiate larger DMA transfers, thereby effectively increasing I / O protocol overhead as well as arm movement and head settle times inside the disk drive.
