Don't assume that its actually a pair of SSDs under the hood. It's very likely that its actually ~8 SSDs md/LVM'd together as two volumes(JBOD, no raid). I'm pretty sure they've taken steps to ensure that TRIM is working, as they'd burn through drives/complaints too quickly otherwise.
That said, you're absolutely right about being cautious/not RAIDing the volumes. There are almost no RAID configurations that support TRIM at present, so it's definitely not a good idea to be RAIDing up these drives. Just go JBOD.
