3ware 8500 SerialATA RAID Controller Review (page 10)Category: Storage by Alexander Yuriev , Nikita Nikolaichev [ 02/05/2004 | 10:14 PM ] Performance in Intel IOMeter FileServer & WebServer PatternsThese patterns imitate the operation of the disk subsystem of a typical file- or web-server.
RAID0 arrays show nice scalability in speed: the more drives are included into the array, the faster the array is.
There are only 20% of write requests here, so all the arrays show high results, although I can’t explain the slump in the graph of the RAID1 when the request queue depth equals 64. Let’s calculate the performance rating for each array by averaging the controller performance under each workload:
I would like to single out the “mirror” arrays here. Thanks to TwinStor technology, RAID10 took the honorable second place, while RAID1 could have been at a better position if it hadn’t been for the above-mentioned slump in its graph.
The WriteBack caching mode provides slightly higher results than the WriteThrough mode, as the amount of writes to be optimized is quite small here (20%).
