tweaks for 60 gig ssd drive

[leo5111]

wondering what services and stuff can be or should be tweaked for it? thanks

The only thing I have to suggest when it comes to SSD's is to either use ext2, or if you use ext3, add commit=60 to the options in the fstab for every ext3 mount on the SSD.

# /etc/fstab: static file system information.

# -- This file has been automaticly generated by ntfs-config --
#
# <file system> <mount point> <type> <options> <dump> <pass>

proc /proc proc defaults 0 0
# Entry for /dev/sda1 :

# Entry for /dev/sda5 :

/dev/sdc5 /media/New\040Volume_ ntfs-3g defaults,locale=en_US.UTF-8 0 0
thats my fstab where do i put that? and what does it do? thanks

Well, the question here is which drive is the SSD? If it's the one running linux, you'd place it like so...

UUID=1130dd2d-c3c5-48cc-8685-cb981c65c995 / ext3 relatime,commit=60,errors=remount-ro 0 1

If it's one of the "New" ones with the NTFS partitions, there's nothing you need to do.

its a ocz vertex 60 gig this one Newegg.com - OCZ Vertex Series OCZSSD2-1VTX60G 2.5&#34; 60GB SATA II MLC Internal Solid state disk &#40;SSD&#41; - Solid State Disks when i installed on it i did what they say to do i cleaned disk with diskpart made alignment marked it as active then booted up installer installer formatted it and installed the OS, and yes this is my OS drive nothing else on it besides a virtualbox , virtual drive i made thanks

Okay, then you'd make the above insert. It has to be done with root privileges, so you need to use some form of sudo with the chosen editor. I don't know if you chose kde or gnome for your desktop, but I'll give you the gnome instruction since it seems to be the most popular:

* [Alt + F2]

* In the command pop-up: gksu gedit /etc/fstab

* Next pop-up: your password.

* In gedit, make the above mentioned edit, then save.

* Restart the computer.

This will help prolong the life of your SSD by increasing the journal write time from every five seconds to once a minute. It's a balance between acceptable risk in the event of a crash (only up to the last minute of work can be potentially lost) and using up write cycles on an SSD; the default setting could kill the drive early, adding 'commit=60' should give it a comparable life span as normal drives.

someone suggested changing it to noatime should i change it to noatime as well as youre tweak? thanks

[D-cat]

"noatime" will disable the updating of the "last accessed" inode metadata. If it's not information you need, then you can add noatime for additional prolonged lifespan and as a bonus up to a 4% increase in performance.

Approved.

Just to add to D-cat's very helpful advice. A SSD has a limited amount of read/writes. So, you want to limit the amount of times the operating system writes to the disk. You should use a non-journaling filesystem like ext2, whereas ext3, ext4, jfs and xfs are journaling file systems.

Another way to limit the read/writes is to eliminate the swap partition. This would force the system to use the system memory for everything, so you should install the maximum amount (usually 2GB for a 32-bit system).

I recently replaced the 4GB SSD in my Eee PC with a 64GB SSD, and I installed Ubuntu that way.

EDIT: If you are running windows as a virtual system, you should know that it has a "swap" file also. It is called "Virtual Memory" or the pagefile system. You can control how windows manages this too.
