I'm affraid even in case of SSDs missing controller-cache will have negative impact on performance, with solo/raid ratio being similar, as for HDD (so instead of ~500MB you will get maybe ~50MB/s from SM863). If you buy such an expencive SSDs, it is a pitty not to use them properly. Two options come to my mind:

A: get some 2nd-hand/used controller. I got mine M5016 on eBay, for ~200$, including cache and super-cap. One year later I found one more for ~60$ (some ISP was selling spare-parts).

B: pass-through your disks/SSD to one VM, and create NAS with software-raid, for hosting other VMs. NAS-OS will do disk-caching and with vmxnet3-nics on local vswitch you'd get quite good network performance...
