If anyone has a KT600 (or KT400A) motherboard, an Adaptec SCSI card and Adaptec SCSIBench, I have a benchmark request: SCSIBench same-sector reads with 224kb blocksize from a recent-model SCSI drive and tell me how fast it goes.
On my KT333 board, there were bandwidth problems. It reached about 72MB/sec if I disabled the PCI-based USB 2.0 controller, or about 49MB/sec if I didn't. On nForce 220D and nForce 2, I get about 120MB/sec, which is basically the practical ceiling for a 32-bit 33MHz PCI bus.
Considering that the drive's sustained-transfer rate is close to 60MB/sec with bursts peaking who-knows-how-high, I wasn't content with 49Mb/sec 😛 I battled the issue for a while to see what could be done about it, and gave detailed bug reports to VIA and Asus (no response/no response), and eventually just retired that board to my home system and used nForce 220D, and eventually nForce2, at work. Incidentally, my lowly ECS K7S5A was not far behind the nForce/nForce2 results either.
If it weren't for this disappointment in my past, I'd be a little more open-minded about VIA SocketA chipsets. Anyone who has an Adaptec x9160 and SCSIBench is welcome to lay that question to rest 🙂
