Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

Yepp I got the Sil3112A running with a RAID1 setup for a data disk (not /).
Used mdadm to do the raid setup (and cfdisk / sfdisk and mkfs.ext3) on debian testing.
I had a lot of hard lockups when the controller was busy mirroring to the other disk. Only current workaround is to boot with options acpi off and no apic (add append="acpi=off noacpi nolacpi" for your lilo config)
So far it works fine, but speed is still an issue (well it actually is fast, but not as fast as one would expect from the serial ata drives).
AT least the samsung spinpoint are quite as a dead goat.
I got my Promise 20376 SATA to work under linux 2.6.x under Debian (MoBOA7V8X) as "/" and RAID1 (md0=swap md1=/)
It is actually not that difficult to get 2.6.2 to work (I am a newbie).
Note that the SATA support for VIA and Promise is "hidden" under SCSI something and not were the other IDE driver stuff is located.
A hdparm with my SATA-drivers yields 57 MB/s compared to the only about 30-40 (max!) of my PATA (optimised!!).
Since Maxtor offers SATA-drives with a 24/7-configuration at an affordable price they do in fact serve as "poor man's SCSI"-drives.
Furthermoer the cables are much smaller and can be longer - a nice feature in large server towers.
I use a Maxtor MaxLine II Plus 250 GB. They are build for 24h 7days a week. They are however not the fastest drives on the market.
Samsung is faster but to my knowledge not build for 24/7.
Either way: Ensure REALLY good cooling (passive alone won't do I guess)
But before you buy a drive, start thinking what U wanna do. Is it going to be a server or a desktop machine?
For a server it would e.g. make sense to buy 4 smaller drives and build an 2 Arrays of RAID 0 with 2 drives and make a RAID 1 (mirror) out of both.
NOte that if yu have many clients using different drives for the total capacity will increase overall performance (since two or more drives can search for different data simultaneously.)
For a desktop one big drive might be better (or 2 if you look for performabce via RAID 0 or security via RAID 1)
I have Red Hat 9 installed in a RAID-0 configuration using the onboard SIImage SATA RAID controller (sii3112). I used the driver provided on Silicon Image's site. It's not easy top find it though.. you have to go to their homepage (http://www.siimage.com) and search for "drivers". Then, click "Downloads" on the left frame. They're well hidden.
