I don't know about Areca but 3ware certainly. I have never come across
issues with any 3ware boards hardware-wise. I suppose you have an
opinion about Adaptec 2405 and its other new lines of real hardware cards?

The guy asked for real hardware raid card suggestions. You can preach
all you like about software raid, there are cases where hardware raid
cards with sufficient resources will offer better value.

I don't know about you but where I work, one of the first infrastructure
issues I dealt with was upgrading from Fast Ethernet to Gigabit. The
teachers all appreciate their logins running faster, the loading of
their multi-megabyte powerpoints being faster, their on-disk gallery of
school trip pictures loading faster, etc. In this age of files being
megabytes in size even hundreds, a ten megabyte/sec network does not fly
anymore.
BTW, I use raidz so as I do not need to hit anything over 100MB yet and
2 TB storage is sufficient for the moment. Good luck trying to get a
controller card that has 8 ports or more without even a fakeraid bios. I
am so happy that there are many motherboards that come with 4 SATA ports
and work under Linux. But find one that also has a PCIe 4x slot is a
pain in the neck.
