[SOLVED] Is this /etc/fstab right for SSD

[dubigrasu]

Is that ^ OK ?

[TabletHater]

You know, most SSDs those days do internal garbage collection and trimming, so mostly this is not really needed.

Actually I had read this before in my Mac days:

But my impression was that garbage collection was exclusive to OWC. My current SSD is a 60GB TEAM XS1 SSD and I don't think it supports garbage collection.

Is what OK?

But my impression was that garbage collection was exclusive to OWC.

Well, that's just some marketing nonsense, writing "our SandForce controller does this and that" actually
mostly all SSD's nowadays use SandForce controllers, so they all technically support garbage collection.
BTW SandForce Controllers are an industry standard, and no innovation by OWC as they seem to make believe.

For reference: http://en.wikipedia.org/wiki/SandForce#SSDs

They also do write optimization, so that you don't get into problems common like with older flash storage,
like wear-leveling where some flash cells simply break (wear off) after, say after 50000 write cycles.

Dok, what do you think about setting up web browsers for SSD? Is that another needless hassle? If not, do you know how to do it in Konqueror/Rekonq? I'd like to try the native browsers.

Sure. Actually i really like the pun about discard


@TabletHater: Well, actually it's the other way round, you should setup the browser to not use the SSD
as the browser cache will produce an enormous number of writes, which is not wanted. There was an extensive
article in a german aptosid forum, which i sadly can't find again, not even via archive.org or google cache.

EDIT: Uhhh, wait, found it again: http://siduction.de/index.php?module=news&func=display&sid=32

It's really detailed and also mentions firefox setup for SSD. A must-read.

For konqueror/rekonq: It should use /tmp/kde-[username] as all other KDE apps.
But as i haven't used the former in years as a webbrowser and the latter not extensive enough i can't really help with that.

Maybe you should change the whole KDE to use tmpfs for the cache?

[TabletHater]

Thanks a lot Dok for the trouble you've taken to find that article.

Maybe you should change the whole KDE to use tmpfs for the cache?

This sounds nicer. How? Or have I already done that?

none /proc proc defaults 0 0
none /tmp tmpfs defaults 0 0

[doktor5000]

none /tmp tmpfs defaults 0 0

Yep, that should be it, that can be easily setup in drakboot's advanced options.

[TabletHater]

So next time once doing that, I won't need to configure Firefox or Opera any more?

[doktor5000]

No, it only means anything saving to /tmp (as KDE does by default, and others) will use tmpfs, so write to RAM not to disk.
But Firefox by default saves to ~/.mozilla/firefox/<profile-id>.default/Cache which should be changed as per above linked article.
Don't know for Opera, though.

[TabletHater]

Thanks Dok; I've learnt how to do it for Opera.

Since you're here, could you tell me how to login to Razor-Qt? I've just installed it now, but need something to change the default KDE to Razor.

All right. Sorry Dok. Disabling autologin returned the kdm login options. I'm in Razor now and and and it's extremely easy to have a proper date and time in its panel!!

Thanks. Good thing we now have unlimited time to edit our posts.
