With darktable it is going to be an unnecessary waste of time and effort
copying images to and from hard disk like that. If you have a small enough
collection of photos (or deep enough pockets) you could keep them all on SSD
but I certainly wouldn’t bother manually copy working sets backwards and
forwards – that is likely to take longer than the time you might save i.e. it
is both more effort and slower. If you are into Linux system engineering you
might set up an SSD cached HD volume and use that for the image storage and
get some benefit without complicating your workflow.
What is really easy, and will buy you more speed than fiddling about with
image storage locations, is simply to have your home directory, and hence the
thumbnail cache, on SSD.
You could also set your final export directory to SSD for a small speed
increase but I wouldn’t bother as it only writes there once and for large file
sequential writes hard discs are pretty fast anyway.
What would be *really* nice would be if darktable had an option to store the
.xml files in a separate directory to the images. Then we could store all
those small .xml files on SSD while keeping the image files themselves on
simple disk and then it would really fly for multi-image operations. But we
don’t have that yet in darktable.
Rgds,
Rob.

Subject: Re: [Darktable-users] Use for SSD?
I'm currently on a workshop for photographic workflow where it's mainly about
developing effectively many raw images.
The goal is to find the developing steps that are the same for many images and
than use this steps automatically on all these images.
So, the teacher uses a SSD for storing the images he is right now working on (
he is also using this CL thing. Power of graphics card ) to speed up the
developing process.
After processing he copies the developed images and XML files back to HDD
and/or backup drive.
I just got a 250GB SSD and will see how that can speed up my developing process.

People are getting crazy when it comes to lowering write cycles on SSD !
While it was a problem some time ago; it is completely solved with TRIM and
internal controllers.
For example look at:
http://techreport.com/review/25320/the-ssd-endurance-experiment-22tb-update
Its not really representative of the daily use of the SSD but it gives an idea
of the endurance of this type of storage.
SSD is now a safe storage system; moreover when you will a cell; it becomes a
read-only memory, no data is lost. But it's really not the best value/memory at
the moment; and it's advantages are not really interesting for casual storage
purpose.
That was my 2 cents, bye :)

Sure, I do backup on a RAID disk (rsync) plus on an external storage
provider (scripts) every night between 24h and 7h. But the message I
responded did not talked about backup :)
