That sounds like "pop in another 250gig drive and let it expand the
array" to me :)
Am I incorrect in my interpretation?

From: http://www.linuxmafia.com/faq/Hardware/sata.html
"LSI Logic MegaRAID SATA 150-4 (four ports) and 150-6 (six ports)
Serial ATA RAID Host Adapters — work with 2.4.x kernel's megaraid2
driver (same one as for SCSI). Cards use an Intel GC80302 dedicated
I/O processor. This chipset, under its former AMI brand name, has had
a long and excellent history with SCSI gear. Real hardware RAID.
Optional battery backup unit is available for the model 150-6 card's
cache, for more reliable operation in the event of power loss, etc.
These cards should not be confused with the low-end LSI Logic MegaRaid
SATA 150-2 card (which please see)."

I looked at the Adaptec stuff, but I wasn't impressed by it's
performance compared to the 3Ware and LSI kit.

The main job for this array will be as a high-demand FTP server and
Samba server.

I'm getting the 6-port card because it allows more flexibility and room to grow.
