Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I've just bought a new SSD hard drive:
Kingston SSDNow V-Series SNV125-S2/128GB 2.5'' 128GB SATA/300
The question is which filesystem whould you recommand and why?
BTRFS vs NILFS2 or EXT4?
If you choose ext4 would you enable jurnalling?
I'm very close to choose Btrfs.
Any experience with running any of these on your SSD?
The wiki can be slow on occasions.
btrfs as a "normal" filesystem seem stable enough - but you'd better be really current on kernel level. But it's not finished; last I looked (about 10 days ago) fsck still didn't work, and the RAID10 recovery is broken (normal disks, not SSD).
I use btrfs on test machines - when I'm happy some of the wrinkles are ironed out I'll look to move it onto other machines.
I read this thread after wondering which FS to use on my Intel X-25m and thought about going EXT4 after reading the the website that I'll post below (the forum won't let my first post include a website!)

My primary concern though is not performance, but how long would flash last given the same workload, which is mostly sqlite atm.
I'm planning to run these on nbd to see the io patterns:
ext4 without journal with stride and stipe size equal to flash erase block size
btrfs with ssd_spread without treelog (?)
Would be nice to hear an educated comment in this thread, or if not I guess I have to as on the mailing list.
I'd be quite interested your findings on this topic since this thread went cold. Or links to any other discussions with good info on the matter. Thanks!
Well, even though this thread is a bit dated might I suggest mounting /tmp to your RAM disk? I believe flash videos (while open) are placed somewhere in /tmp. If you have spare RAM to mount it in, you can use that.
