I'm thinking of re-installing Gentoo on an Intel 40 Megs SSD -- excluding the
most often writen dirs like /var, /tmp, /home --. What do you think ? I'll be
glad to hear about previous experiences. What about swap ? Is it safe to have it
on the SSD ?



Hi,

i have a Gentoo System on SSD running for a while now. No problems.

I have / on ssd, but /tmp on tmpfs, /var on harddisk and swap on harddisk.

I don't want to wear it down ... and 40gb is not that much.

I run minimal servers on 4 Gig Compact Flash-2-ide. Similar but not as
robust as SSD. You should not have any problems, if you PLAN, THINK through
your intended application(s) and ASK questions on this list...... methinks.


caveat emptor,

Hmm, I see massive crashes with my Intel Postville G2 80GB, in the last
2 days ... maybe I have received a bad one ... shouldn't be the same for
all of them.

Gentoo didn't detect it anymore ... etc.

I still try to decide how to proceed. Maybe completely reset it and
start from scratch.

Just my current experience with this specific device ...

Why exclude the most written dirs? I thought SSDs were projected to
last longer than HDs? Also, from what I've read, SLC should last much
longer than MLC.

It's the other way round: HD's last longer dan SSD's. [1]

Thanks for the link. I did some Googleing too and I'm really
surprised at what I found. It sounds like SSDs don't have the
projected longevity they did when I researched this a year or so ago.
I'm troubled by the ever-lurking possibility of an HD failure and I
thought SSDs would be my way out. Is an HD the best choice for
reliability?

depends. Intel for example slows down the ssd if you write too much to prevent
premature failure.

HDD are prone to mechanical failure. SSD not. If you only do moderate writing
SSD are much more reliable. If you do a lot of writing - douzends of gigabyte
a day with a lot of overwriting, a HDD might be the better choice.

I still don't know.

I had the impression that having my home-dir on the ssd lead to
filesystem-problems ... maybe all those tiny writes ... I don't know.

Could be fs-related as well ...

Moved my home back to hdd as recommended by Volker here a few months
ago. Only having my root on the ssd worked OK for quite some time
(sidenote: how to do that on my thinkpad? Having it hdd-free is one main
reason to move to ssd ...)

As mentioned I faced some hefty crashes in the last days ...
unfortunately I wasn't able to record the logs as the drive simply
disappeared. I thought I had the latest "dmesg > myfile" on hdd but it
was empty after a reboot ....

Currently I am back on my raid1-hdd-root ... slower but OK ;-)

The crashes happened with tuxonice-sources-2.6.32 -- dunno, if the
latest ebuild brings some changes helping in this context.

Maybe it's ext4-related as well ... you know, many moving parts in a
modern system ....

A single drive, be it HD or SSD, is always at risk of failure. If this is
a significant concern, you should be using some form of RAID, along with
regular, automated backups of course.
