thanks hoggis for more info,
if your main drobo is back to all green, that is good, but i think if you try shutting down the drobo via dashboard, and then restarting your computer, dashboard, and the drobo again, does the ssd status still show the warning?
if so, it might be worth raising a ticket with the support team (especially if still in support), just in case they can spot what is causing that in case there actually is an issue, for example, maybe that ssd is running low on spare sectors in the ssd sense, or spare cells). Usually that is not as much of an issue on the larger ssds, but is probably worth investigating further with support of you can.
alternatively, there might be some free utils that you could try using to analyse the ssd yourself (though you would need to shutdown from dashboard and shutdown all and unplug all power etc , and carefully remove the ssd, without tilting the drobo which can damage the backplane if drives are still inside, and then put things back again, including drives if you removed them, and then power back up and continue etc) - in some cases it may be worth raising a ticket for the diagnosis, (even for a small one time cost in case out of support, rather than doing the above steps, though whatever you feel happy or comfortable to do is up to you)
