I'm considering the SuperMicro X5DAL-TG2 motherboard and non-ECC, unbuffered RAM to save/switch around costs. A few questions:

1. Beyond the 4 connectors (4 WD 250 gig SATA drives = 1 TERABYTE!!!:D), are there any practical, real world performance reasons to use a separate SATA controller card?

2. Are there performance gains using ECC Registered Buffered RAM vs. the minimum configuration?

3. For 2 gig of RAM, are 2 1-gig sticks better than 4 512k sticks?

4. Any advantage to 1 meg cache Xeons vs. 512K cache Xeons?

If I've left anything out, please enlighten. Thanks.

1. The X5DAL-TG2 uses Silicon Image SATA controllers - they're not the fastest (RAIDCore are the best) but they're still very good - certainly as good as a PCI Silicon Image solution.

2. Nope - the X5DAL-TG2 likes normal non-ECC PC2100 DDR RAM just fine.

3. Yup, but only 'cause you can add another 2Gb if you need too.

4. In theory there should be a (marginal) performance gain - couldn't say for sure.

If you're putting this together for a VT[3] and no. of streams is an issue then regular SATA drives aren't going to cut it - I'd suggest 4 x 74Gb Western Digital "Raptor" 10,000 RPM drives - they rock!
