I get 950 Mbps with iperf (w/o jumbo frames). Actual disk to disk, or even disk to memory transfer speeds are at 30MB/s. If you'd read the article I linked to you'd know that.

Actual protocols are a LOT slower than just slamming as many bits as possible through a pipe.

The days of network being faster than disk are over.

Gig-E speed is about 30MB/s in the real world. This is with a crossover cable, machine to machine. I've tested and verified this over a number of platforms, including expensive server systems.

Cheap terabyte single disks these days can do 80MB/s.

The only reason to go with raid is for redundancy, or better handling of simultaneous connections.

China Vows to Stop the Rain 214

Since the Olympic stadium doesn't have a roof, the Beijing Meteorological Bureau has been given the task of making sure the games remain dry. According to Zhang Qian, head of weather manipulation (best title to have on a business card ever) at the bureau, they've had success with light rain but heavy rain remains tough to control. I see a hurricane cannon in some lucky country's future.
