Hey folks,
I looked back through the list archives and there are surprisingly few threads with "SSD" in the subject.
In my new job I've been handed over a number of things that were outstanding with the previous Sys Admin, and one of them was an SSD that was suspect. I just plugged it into a diagnostics laptop to use the Linux Smart software to check it - and it all seems fine even after running the disk test suite from the GUI. In digging for more info I discovered that the errors were actually coming from the RAID controller - and the SSD has obviously been removed from there for the time being.
While I have it in my hands I'd like to do some kind of complete test / diagnostics suite on it. Preferably Linux based since that's what we have here.
I found a few windows-based tools with my googling. I did stumble upon this page which looks like it has a few useful tips for using SSDs on Linux http://danweinreb.org/blog/using-solid-state-disks-on-linux
Now, what about comprehensive suites? Should I just run some IO suites on it like bonnie++ or something like that, and see what SMART says in the process?
I'm suspecting the RAID controller at this point ... but want to be as thorough as possible while I have it in my hands.
cheers, -Alan

test for what you care about really, most people use SSD's for the performance angle. I tend to prefer iozone over bonnie++ these days - there are a host of other perf test tools that might be worth running through, eg the mysql-bench or the pgsql perf test. Depends on what your production workload is and what you care about
