I wonder if there is any one who owns an Iwill KK266R or Iwill KK266Plus-R has ever benchmarked their onboard RAID controllers, i.e., AMI on KK266R and early KK266Plus-R models, and Highpoint on late KK266Plus-R models. I have an Iwill KK266R with AMI and I found out that its disk performance is about 30% worse than a single ATA-66 7200 HD based on the Sndra 2002 File System Benchmark. My system runs Win2K sp2 which includes 2 Maxtor 40G ATA100 7200 drives stripped in 64K in RAID 0. To narrow down the disk performance problem, I di the following 4 addition testing:
(1) Update with the latest Iwill posted AMI driver;
(2) Disable the onboard AMI RAID by using standard master/slave IDE ATA100 controler;
(3) Disable the onboard AMI RAID and install an Highpoint-based Iwill SIDE PCI RAID card; and
(4) Install the same Iwill SIDE PCI RAID card on another Tyan mobo
To my surprise, what I have found out is that none of the first 3 changes make much difefrence. However, (4) did perform close to the reference result of Sandra 2002 File System Benchmark.
It was unbelievable that Iwill will sell such a product without even testing its RAID controller performance. After talking with Iwill tech support, they told me that their late KK266Plus-R models did replace AMI with Highpoint controllers. However, according to my test (3), I stronly suspect their claim. Your input on this issue is welcome.
