Re: Informix data fragmentation or RAID disk

RAID striping (with and without parity) creates large logical volumes which can be partitioned into multiple units. RAID disks can get fragmented like other disks. How it impacts your application depends alot on read/write ratios, random vs. sequential nature, etc. -- so go ahead and ask your RAID vendor to analyze your particular computing environment for the most realistic prediction.
