Does new SCSI card mean revamped hardware?

It's not. RapidIO is actually faster than PCI-X. it also has full support for PCI bridge chips, PCI-style chip to chip and board to board communications as well as InfiniBand-style box to box communications. RapidIO tops out at 7.5GBps. as opposed to PCI-X's 1GBps, AGP 8x's 2GBps and InfiniBand's 6GBps. so while RapidIO doesn't even come close to 3GIO's(Highly theoretical) 10GBps or HyperTransport's 12GBps. it
absolutely blow the doors off of PCI-X, AGP 8x and InfiniBand. as well as having the advantage of very long line runs. plus both inside-the-box and outside-the-box functionality.

So, How fast is it. SCSI 160 has a throughput of ?50MB/s (single 15000 rpm drive). What is the value for SCSI320.

SCSI 160 is 160MB/s just like the spec says. No single hard-drive could ever push that much data but a 4 disc RAID array could, which is ussually why people buy SCSI.

There's also something else called Ultra640 SCSI coming down the pipe.

Eric, high bandwidth/throughput technology fetishist supreme, always there to point out a bigger badder version just over the horizon.

For 10k rpm on u160 the sustained r/w for a single drive is ~35-40MB/s. If you stripe the disks, then you're going to get the benefit of more speed ~50-70MB/s sustained. This is from personal experience.
