Damn, I was joking .. I don't really want to go into all the ins and outs of SSD optimisation here unless you actually ARE going to get one .. rather large subject.

As for filesystem .. I'd probably still go for ext4 over btrfs .. for no other reason than it's a known quantity (to me) and Btrfs is still considered "experimental"

There's plenty of info online already:
https://wiki.debian.org/SSDOptimization

There are a lot of SSD optimisation techniques available .. some are a trade off between ease of use, performance, longevity .. so usage patterns also come into play

Easiest option .. make sure the SSD supports TRIM and use ext4 and use the discard/noatime mount options .. others will say manually running trim improves overall performance .. others will go further moving caches/buffers to RAM, changing the I/O scheduler, creating the ext4 filesystem with journalling disabled, and adding other mount options such as nodiratime.

Gimme a shout if you decide to get one .. VinDSL also has some good ideas about SSD optimisation, so he'll no doubt be able to help too :)

i was thinking about an SSD actually... but something tells me i'd have to reconsider the sorts of partitions i use ... btrfs or jfs as opposed to ext4?

EXT4 is the preferred filesystem for SSDs.

Here's a BootChart screenie: 6-year old Dell notebook with a $65 USD SanDisk SSD (EXT4 FS).

11-sec boot -- 290MB/s disk throughput -- on Peppermint 4 Re-Spin. ;)

11 secs.... interesting VinDSL ... might hafta ponder... and no i wasn't going to ask you to go thru all the ins and outs here PCNetSpec

my bootchart is a bit longer ;)


EDIT been doing some reading on SSDs this am... thought y'all might enjoy a link... I suspect my laptop's interfaces would negate any speed benefits of replacing the HD with an SSD http://www.storagesearch.com/notebook-ssd-market.html

So I'm off to nail down this touch pad once again :x ;~)
