Hi,
currentlu I am setting up a new PC for my 12-years old one,
which has reached the limits of its "computational power" :)
SSDs are a common replacement for HDs nowaday -- but I still trust my
HDs more than this "flashy" things...call me retro or oldschool, but
it my current "Bauchgefühl" (gut feeling).
Can't remember where it was - some mag ran a stress-test on a bunch of
SSDs and they massively outlived their rated lives ... I think even the
first to fail survived about 18months of continuous hammering - and I
mean hammering!
To reduce write cycles to the SSD, which are quite a lot when using
UNIX/Limux (logging etc) and especially GENTOO (compiling sources
instead of using binary packages -- which is GOOD!), I am planning
the following setup:
The sustem will boot from SSD.
The HD will contain the whole system including the complete root
filesustem. Updateing, installing via Gentoo tools will run using
the HD. If that process has ended, I will rsync the HD based root
fileystem to the SSD.
Whatever for?
Folders, which will be written to by the sustem while running will
be symlinked to the HD.
This should work...?
Or is there another idea to setup a system which will benefit from
the advantages of a SSD by avoiding its disadvantages?
If you've got both an SSD and an HD, just use the HD for swap, /tmp,
/var/tmp/portage (possibly the whole of /var/tmp), and any other area
where you consider files to be temporary.
Background: I am normally using a PC a long time and try to avoid
buying things for reasons like being more modern or being newer.
Any idea to setup such a sustem is heardly welcone -- thank you
very much in advance!
Why waste time and effort for a complex setup when it's going to gain
you bugger all.
The only thing I would really advise for is that (a) you think about
some form of journalling - LVM or btrfs - for your root file-system to
protect against a messed up upgrade - take a snapshot, upgrade, and if
anything goes wrong it's an easy roll-back.
Likewise, do the same for the rotating rust, and use that to back up
/home - you can use some option to rsync that only over-writes what's
changed, so you do a "snapshot then back up" and have loads of backups
going back however far ...
Cheers,
