Jeff those numbers look great to me, but I'm no storage expert like Jamie or Bill. The main advantage you are going to see is the load being completely taken off the CPU. IIRC, that RAID card is very fast. Of course if you go to xs they will say it sucks because its not the latest and greatest.

Looking at single drive benchmarks, you probably STILL will not maximize the Vertex's potential with that raid controller. AT supposedly 250 MB/ read speeds 3 of these drives would probably max out the 800 MHz IOP controller in practice. 4 would definitely be bottlenecked by the card and Write performance will probably bump the ceiling as well.

So now I am even more confused. I have been reading most of the day and some of what I was reading was that unless I was going with a raid level 5 or 6 the onboard controller provides no real benefit. Others swear by the on board controller regardless of the level of raid. Rocket Raid has a controller with the Intel IOP348 however this card is not compatible with the OCZ Vertex drives. I have also read that Sata raid contrllers are better than SAS/SATA the ones with the fan out cable but the people were argueing over .024ms access times. Any suggestions and all advice is greatly appreciated. |
