[dba-Tech] Software Firewalls

Well...since the PCI bus is limited to ~127MB/sec you would still incur the
bottleneck.  Even at SATA2's limit of 300MB/sec, you can only transfer the
hard drive's cache...IIRC the current drives can't even saturate the current
PATA/133 bandwidth.

On the other hand, I believe the upcoming PCI Express 2.0 is slated to have
5GB/sec.  Now that would be nice...incorporating huge amounts of
removable/upgradeable flash RAM storage onto that bus...whoohoo!

What  I'm waiting on is a good inexpensive cache controller with about 512mb
on it
