We are currently exploring installing openSUSE on a system with SSD storage. I am curious what others have experienced with these disks. Specifically,
1. What version of openSUSE has the best support? I guess the obvious answer would be 12.1. But what version first had decent support? The SSD suppliers suggest that Linux kernel 2.6.33 is a minimum requirement.
I use 11.4 and am satisfied with its support.
2. What SSD features are good to have and are supported in openSUSE?
Do not use mount option discard, it effects performance negatively. (That's validated up to kernel 3.0, and might change in newer kernels.) Don't use a distribution with a kernel < 2.34. Use fstrim in a cron job. I don't know when it appeared in a SUSE release, 11.4 has it. If you can afford it, don't use 15% of the disk. To get this free space, use secure erase to reset the disk's firmware notion of what you're using, and then don't allocate 15% of the disk during partitioning.
3. What outstanding issues are there that might make one think twice?
smartd support is said not to be solidly available for all SSD disks. But the problem is that this kind of gossip is not validated, and hard evidence is hard to come by. Enterprise SSDs have proper support anyhow, Intel disks seem to be OK, too, and I've got a Crucial C300 that seems to work as well.
