    I really need some advice in this area as i'm a newbie. By the way question two should read: 2) Since i need two independent channels for the two raid setups, i need a scsi enclosure that has independent external u160 connectors on the enclosure to do this.

    Terrible SCSI RAID Performance--Desparate need of HELP

    by the way if you use or know any thing about ATTO Benchmark scores could u clarify something for me. I know you should use 32MB for the total length field box, but what about transfer size--to get an accurate reading. it goes from .5MB to 4MB. Just wondering here.

    when u say bios setting on the drives themselves, you are referring to the scsi bios/ motherboard bios settings, right?

    Terrible SCSI RAID Performance--Desparate need of HELP

    The reason i got the 15K Fujitsu Drive over the Cheetah or IBM was becaused they outperformed them in every test on the review on Tomshardware. Doing a new install you can make any disk basic or dynamic with out any regards to what it was before, right? The cabling on these drives are all...

    Also, why am i getting such crappy ATTO benchmarks on the Adaptec 39160 SCSI controller. Just one device (15K U160 Fujitsu hard drive with only the OS and benchmark programs installed) is installed on the controller. I'm getting a crappy 30MB/sec. It's a basic disk though--can you convert a...

    Terrible SCSI RAID Performance--Desparate need of HELP

    I have tried both dyanamic disk and basic disks with WindowsXP and they both give similar poor results. I should be getting right over 100MB/sec with my setup. I wish i could get a 64bit PCI slot, but they usually don't have the right AGP slot or enough pci slots (i need 6--can do with 5...

    Terrible SCSI RAID Performance--Desparate need of HELP

    I forgot to add this, which may mean that my motherboard (Asus P4t533 (not-c)) is not limited to just 90MB/sec. When i ran ATTO with a file size of 4MB i was hitting right over 100MB/sec, but this was probably due to the 128MB of cache on the SCSI RAID Controller. To get the true performance...

    Thanks for the info mechbgon. I'll be testing it all week. But shouldn't I be able to hit 90MB/sec or at least close to it with my set up. Any other ideas of what i can do. Anyhow, ASUS and Intel are going to get an ear full today. Needless to say i'm extremly pissed off about this. Asus...

    Would this effect the latest P4t533 motherboards? I heard the earlier ones had some problems but the latest ones out were much better. Would a firmware upgrade from Asus fix this--i have the latest now. Also, I need USB 2.0., so disabling it would render USB 2.0 inoperable, right? I have a...

    Terrible SCSI RAID Performance--Desparate need of HELP

    My motherboard is the Asus P4t533 with the Pentium4 3.06Ghz and 1GB of Rimm4200. Also, i have updated to SP1, but have had no success. My disks are also dynamic. I've looked on storagereview.com and looked at all their comments regarding this matter, too. Termination is fine, writeback...

    Terrible SCSI RAID Performance--Desparate need of HELP

    What about the Adaptec 39160 SCSI controller. I'm only getting 30MB/sec with that. The 3400s cost over $1,000. I don't believe it could be that bad. I've converted to dynamic disk to no prevail. Something is going on, but i just cant figure it out.
