Chipset Serial ATA and RAID performance comparison

 

 

"Of course, I would be remiss not to point out how little performance impact different RAID levels had in our application benchmarks and stopwatch tests. Although multi-user and synthetic disk subsystem tests like IOMeter, HD Tach, and ATTO show clear differences between the performance of each RAID implementation and array configuration, the performance benefit in more real world applications is significantly less pronounced. Power users who regularly stress IO performance will no doubt notice a performance benefit moving from a single drive to striped array, but for less demanding users, the redundancy benefits (with no performance loss) associated with a mirrored array may be a better justification for adding a second drive.
