New SATA PCI card findings

This will be brief...  as there really isn't much to tell, but a more recent finding has changed everything for me.

About three or four years ago, I had come to the conclusion that booting from SATA PCI cards was only about 99.9% stable.  This is because every so often things would just lock up system-wide, and I would be forced to do a hard boot.  Not a good thing when you're smack dab in the middle of important work.  After tolerating it for a couple years...  I finally decided that I would stick to SATA card attached drives for storage only, and boot from IDE/PATA drives instead.

About four or five months ago, I realized that during all those system lockups I had drive sleep enabled.  So I decided to try it for a while without any type of sleep enabled, other than display sleep, which has no effect whatsoever on hard drives.  I never use system sleep, as my systems are always 24/7 on, but I normally use drive and display sleep on every OS.

So I have now been running a WD Caviar Black 2TB as my boot drive for about five months, with drive sleep disabled on every OS, and have never once had an issue.  I have now found 100% reliability with SATA card booting!

The WD Black is the perfect drive to use in a system where drives don't sleep, because it's built for higher endurance than most drives, and has more performance to go along with that.

I had already tried every version of firmware for my FirmTek SATA cards, and nothing solved it, but disabling drive sleep did.  The only real difference now in my computing habbits is that I need to unmount all the externals I'm not using, since they are typically backup drives, and don't go to sleep any longer. 

Keep in mind that these finding are all based off use in two Sawtooth, along with one Gigabit Ethernet system.

Anyway, I had told some readers in the past via comments that SATA card booting wasn't 100% stable, and I just wanted to share how I did find that sweet spot on my hardware.

For the record...  this is all with the FirmTek SeriTek/1S2 PCI controller; I own three.  The Sonnet 2-port PCI is the same card, as they are made for Sonnet by FirmTek.  By the way...  the best firware to use in G4 towers is 5.1.3.  You still need to disable drive sleep, but the newer firmware (5.3.x) is meant for early G5's with standard PCI, and most of these cards ship with the newer version.  So if you have a G4, and you have the 5.3.x firmware, you need to downgrade to 5.1.3 for best results.  You can download the 5.1.3 firmware here.

Please share any SATA PCI controller stories and findings you may have in comments.
