It's there. SATA1 = 150 / SATA2 = 300. You need an interface
(card/chipset) that supports SATA2 if you go that route. There is no
incompatibility between the two except if your SATA connection only
supports SATA1. At which point, the SATA2 drive would operate at SATA2
transfer speeds. No daisy chaining at all with SATA. Each SATA drive
gets a single connector cable that goes from it to the controller. No
terminators are necessary as a result.
I have 8 SATA1 drives in a Raid-5 on a Highpoint card. Works just fine
with 2.6 kernel.
I also have a workstation that runs 2/150 and 1/300 drive running a 2.6
kernel. No issues so far.
I've also booted a myriad of other machines from other live Linux
The important thing to keep in mind is that the kernel typically shows
the drives as sd* and not hd*.
