In a fedora forum, I found this list for SSD-optimalization. I've just baught a new laptop with a Kingston 80GB SSD (which is a rebranded Intel X25-M), and plan to install Ubuntu on it. Im going to run dual boot with W7 for games.
What I understand so far, is that I should use ext4 without journaling, and that I should do some other tweaks.
The question is: Which parts of this list should I do, What needs to be changed in order for it to work in Ubuntu, What can I skip, and is there anything else I should do?
SSD Optimization
Perform the following if you’re using an SSD. If you’re using a hard drive you can skip this section.
Create Ramdisks to Store Frequently Written Areas

1. Edit your /etc/fstab file. Add the following lines.
tmpfs /var/log tmpfs defaults 0 0
tmpfs /tmp tmpfs defaults 0 0
tmpfs /var/tmp tmpfs defaults 0 0

Disable Access Time Attributes

1. Edit your /etc/fstab. Modify the root partitions settings. Add noatime and nodiratime to defaults.
/dev/sda2 / ext4 defaults,noatime,nodiratime 0 0

Optimizing the Kernel

1. Add the following to your /etc/rc.local file.
# Economize the SSD
sysctl -w vm.swappiness=1 # Strongly discourage swapping
sysctl -w vm.vfs_cache_pressure=50 # Don't shrink the inode cache aggressively

# As in the rc.last.ctrl of Linpus
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
cat /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate_max > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate

echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
echo 20 > /proc/sys/vm/dirty_ratio
echo 10 > /proc/sys/vm/dirty_background_ratio

echo 1 > /sys/devices/system/cpu/sched_smt_power_savings
echo 10 > /sys/module/snd_hda_intel/parameters/power_save
echo 5 > /proc/sys/vm/laptop_mode

#Decrease power usage of USB while idle
[ -w /sys/bus/usb/devices/1-5/power/level ] && echo auto > /sys/bus/usb/devices/1-5/power/level
[ -w /sys/bus/usb/devices/5-5/power/level ] && echo auto > /sys/bus/usb/devices/5-5/power/level

/sbin/setpci -d 197b:2381 AE=47
/sbin/modprobe pciehp
/sbin/modprobe sdhci

Change the I/O Scheduler

1. Edit the /etc/grub.conf file. Add “elevator=noop” to the kernel line.
kernel /vmlinuz- ro root=/dev/sda

I've run Ubuntu for a year now, but I'm still not completely sure on commands.

Thank you.
