Also, it shows 2 of the ports are running as 3.0Gbps (which is strange as I thought all of the ports on the mainboard were the same 1.5Gbps speed)
The 3 maxtor drives were purchased as SATA2 spec.
Is there a way to tell what ata?.00 corresponds to sd[a-d]? So that I
you can identify them easily using e.g. "smartctl -a -d ata /dev/sda" or "hdparm -i /dev/sda". Those commands return the model and firmware-revision which you then can match against ata1-ata4
can RAID the 2 faster drives together. Or does the kernel assign in order (e.g. ata2.00 = sdb)? Or won't it make much difference?
it won't make much difference as long as you put two of the three STM3250310AS together (preferredly those with the presumably newer 4.AAA firmware). You may be able to switch the two 1.5Gbps drives into 3.0 Gbps mode by using vendor tools, but individual drive speeds are below 1.5Gbps anyway.
