Does chunk size influence the speed of RAID? DiskInternals

WebWhen you use RAID0 (striping), each block of data is written partially to one disk and partially to the other disk (s). Say you write a 1MB file, if you have a single hard disk, it just writes the file. For the sake of argument lets say this takes 10 seconds. WebThe cache disk caches data to the RAID disks. The cache can be in write-through (supported since 4.4) or write-back mode (supported since 4.10). mdadm (supported since 3.4) has a new option ‘–write-journal’ to create array with cache. Please refer to mdadm manual for details. By default (RAID array starts), the cache is in write-through mode. gl bajaj college mathura
