What's yours?

From physically pressing the 311C's power button to finishing loading the desktop fully: 35 seconds (using an Indylix-based SSD and a freshly installed 10.6.4 using your guide).

This is on an N270 model without any overclocking.

^The wonders of SSD! My time is just boot time - apple logo to desktop.

Your boot time of over a minute would be due to your setup's DSDT HDEF + HDAIDT.kext + AppleHDA.kext. VoodoooHDA and the newer DSDT from MowgliBook.

Oh, I see... In that case, my equivalent boot time is about 30 seconds, I guess. :-)
I saw a real bargain last week on a 60GB ocz ssd, and I took the right decision. The best strategy is to always buy stuff when the new generation of equivalent products hits the shelves massively. In fact, I am also waiting for a similar deal on the previous generation's top-of-the-range SSD to put in in my desktop PC (also hackintoshed, although without such a clean "vanilla" install).

Unfortunately, there is a price to pay to ensure the SSD's longevity.
As soon as I replaced my hard disk with the SSD, I had to apply the following absolutely *vital* tricks (gathered from many different forums) to minimize write cycles:

- Disabling swap file: delete /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist , and after rebooting delete /private/var/vm/swapfile*

- Enabling ‘noatime’ (it is usual for unix filesystems to record the ‘last access’ time of every file. This means that every time a file is read, a write is made on the filesystem to record this action): just create a file named “com.nullvision.noatime.plist” in the directory /Library/LaunchDaemons with the following content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
<plist version="1.0">

- Tweaking OSX sleep mode (by default the whole contents of the system’s memory is copied to disk):
sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage

I hope this helps others to safely put an SSD in their hackintosh lives.
