Good to know J_RaD. Computer manufacturer's must publish noise pollution data, so I've been comparing numbers with my current Dell Precision. It looked like the Poweredge's were much louder, but its good to hear from someone who knows for sure.

In production, I currently build my Lucene Index with dual quad core X5570's, 48 GB of RAM, 2 x 600GB 15 RPM SCSI in RAID 1, with a 2 x 64GB Intel X25-E SSD's in RAID 0. I use the RAID-0 as a scratch space, specifically to build the Lucene index. Unfortunately, it isn't big enough for the final optimize step. I'm really looking forward to bigger Intel SSD's. I also could use more RAM, because I am paging quite a bit during some of the pre-processing steps, which involve clustering the data.

I think with about 70+GB of RAM and larger SSD's, my entire search index build will scream along. I've been holding off on upgrading my back end production server until I can get faster I/O with larger SSD's. Hopefully in the first quarter of 2011.
