Can RAID bottle down a P4?

[TheNEWB]

This is just a generic question?

My crack smoking friend jsut set up his RAID array, and well he seems to think that the RAID is sooo fast it actually bottles down the processor. Is this possible, can a RAID array with a 57000 score in sandra possibly bottle down a 2.77Ghz CPU? He says he watched the Tomshardware Video (3.6 vs 3.0HT) and the HT cpu does a much better job a processing data from the array. Yet when I watch the video all I see is that there is only one Maxtor installed for the video?

That has nothing to do with RAID right?

I can totaly understand an array is set up wrong and it uses a lot of CPU resources, but he seems determined to proove to me that the CPU is to slow to process the info coming off the array. Ok ok, this is not even a SCSI array, just two 40GB WD JBs hooked up to SATA controlled through 2xSeriall adapters.

I'm I smoking crack here or is he? Can a device that outputs no where near the true 133MBs (HDD RAID) bottle down a 4.2Gbs device(2.77 p4)?

Thanks for any wisdom on the subject.

no it's not possible since the array runs on the SATA bus which has a maximum throughput of 150 MB/s and even if you actually reach that the processor goes much much faster than that

no.

I'd say it depends on the quality of the onboard RAID adapter. If it's true hardware RAID, then no, the disks can't produce enough bandwidth to saturate the processor. If there's no dedicated hardware though (i.e. winRAID), then it's possible that the processor wastes a lot of cycles managing the RAID setup.

Is the Highpoint Raid controller in Abit IT7 Max2 version 2 is true hardware RAID?????

 

[TheNEWB]

I would imagine.

Since the chip on the IT7 is actually by high point designed to be used as a RAID proceesor then it must be hardware RAID. I personally never saw anything like a windRaid Chip. Maybe theyr a myth.

Peace out,
