[ILUG] tips for using SSD for /

[Darragh Bailey]

Bought a new PC as a early chrimbo pressie to myself, and as part of it
I've decided to go with a 60GB SSD for /.

Reading on some blogs covering use of SSD's I see no reason not to use
ext4 on it. Suggestions to use noatime seem to be limited to the SD
disks used in netbooks and don't appear to be suggested for newer SSD's.

There are also suggestions about keeping the partitions created aligned 
to "erase write boundaries" to help performance.

As there will be 8GB ram in this system, I'll probably use a tmpfs for
/tmp. Not sure there's any real need for a large swap space, unlikely
that I'll use suspend to disk enough to justify reserving sufficient
swap space for it, although it would be nice to be able to still do it.
Hopefully use of a dedicated hibernate file will work.

I'm tempted to go with a swapfile instead of a dedicated partition since 
I'm using an SSD, there's no real benefit to locating swap space at the 
end of the disk as there would be with a spindle based disk, and the 
overhead of having to write to a file on filesystem is probably pretty 
negilible compared to the overall performance of the disk (Max 275MB/s).


Any suggestions, thoughts or pointers?
