OK, I wasn't aware of this - haven't worked with any new cards in about a
year.

Then "HostRAID" isn't h/w RAID, it's software, much like the infamous
nVidia chipsets and Promise. I don't know if those driver packs are
needed to just communicate with the drives, if not, I'm home safe with
those controllers if I should use Linux' own software RAID.

Make sense then to avoid these

I was afraid of that too.. I'll call my distributor to try to sort it out. As usual, Adaptec aren't too responsive to e-mail questions... (Even though I'm a Adaptec partner..)

I should take a look at 1420SA and 2420SA as well, I just noticed that
they exist, I don't have a clue about what they are/do yet.

According to their website the 1420SA is a HostRAID card.  The 2420SA Is a
normal hardware raid card - aacraid driver - I've used this one.

I'll look into that one a bit closer. But I'd really like a 8-channel card for future expansion, preferably a SAS card, but I'm not so sure anymore...

With emphasis on the words *used to be*, Huberts kernels are no more... :(

Sad that.  My more_than_one_year_old_notebook's ACPI is still not sorted
out (although there are some groundbraking patches in the upcoming
2.6.21).  I'm still not having a 100% successful experiencing building
vanilla kernels on SUSE - there's always something bitching at me.

Hmm... I'm not seeing that, but on the other hand, I don't use ACPI.. (But the wife is bitching at me instead).

I actually haven't heard anything negative about Highpoint so far, not
much positive either... At least they do manufacture quite some chips
for Adaptec, so I guess their stuff shouldn't stink too much?

Which chips do they manufacture?  The RAID controller (shudder) or the
SATA controller?   I remember the LSI SATA-160 card had the LSI RAID card
had three Sil3112 chips on (to control the six drives) and the LSI RAID
controller on top of that.  I assume the RAID controller is the same one
used on the SCSI cards I used (had the same crap performance).

I can't say, I saw a press info on the subject a while back, I guess our friend Google might clear it out.. ;)
