View Full Version : [ubuntu] Best install configuration for SSD

I recently purchased a Thinkpad x301 that shipped with Vista Basic. I'm contemplating a fresh start with just Ubuntu 9.04, but my laptop has a 128 gig SSD, which I've never used before. I looked around a bit for suggestions on install configs, but most of what I found either contradicted each other or focused on after-the-fact tweaks aimed at reducing wear on the drive.

What is the best approach to installing linux on solid state drives? Should I use Ext2, 3 (or 4)? Do I need a swap partition?

In case it's relevant, I only have 2 gigs of ram at the moment, but am planning on upgrading to either 3 or 4 in the near future.

I am running 9.04 on a vertex ssd without swap with 2GB ram.
You might want to check the following for setup:

I am very happy with the performance. I get around 180MB/s with hdparm test.

Thanks for the link. Unfortunately, I'm finding it a bit overly technical and difficult to discern what I should actually be doing during the install.

I'm also still confused about contradictory advice. That link, for instance, says turning journaling off is "not recommended as you might experience a data loss after an unclean shutdown," while a post on this forum (http://ubuntuforums.org/showthread.php?t=866375) seems to argue that a filesystem without a journal is essential for reducing excessive writes.

That post also argues for the use of Ext2. I find it odd that Ext3 and 4 are supposedly so poor at handing SSDs, especially since they're newer. It seems counter intuitive to me.

If anyone, like me, is looking for info on this subject, here is another good resource (http://thunk.org/tytso/blog/category/computers/ssd/). This guy seems to know what he's talking about and has found that using the Ext2 filesystem is only necessary if you have a first-generation SSD.

I use ext4 with journaling. Works great and in my opinion according to the info I have even with journaling your ssd should last many years. I think people get a little bit carried away with overprotecting their ssds.
