3. at least as fast at 100 MB 21 Self certifying File System SFS To reduce request fragmentation for large requests Self certifying File System SFS bypasses the Windows buffer cache and tries to make one request for the entire amount of data The SFS accesses hard disks by addressing entire extents which are flexibly sized groups of blocks With a good disk allocator such as ours extent based file systems minimize fragmentation For example say Windows makes 64 KB requests for buffered I O which results in eight I O requests for 8 KB blocks The SC101 SFS allocator in comparison searches chunks of thirty two 8KB blocks before moving to sixteen 8KB blocks before finally moving to eight 8KB blocks Often files are larger than the maximum Windows request size so Windows files will fragment SFS avoids the fragmentation of Windows The SFS allocator can use both first fit and best fit algorithms and typically outperforms Windows in terms of maximum blocks that can be transferred at a time All this makes it easy for the SC101 to stay defragmented using its own software Another non Windows feature that reduces SC101 disk accesses is stuffed dinodes In the Windows NTFS disk management the addresses for blocks are stored in a different place than the blocks themselves This means that any request for NTFS disk data no matter how small causes two I O operations Since hard disk I O is far slower than your CPU or RAM doubling
