It looks like UNMAP is enabled by default regardless of storage type (SSD vs non-SSD) but if it’s not you can enable it. VMware ESXi is supported only in a complete installation of the MegaRAID Storage Manager software stand-alone, client-only, and server-only modes do not. The storage software LSI Storage Authority (LSA) is the successor of the MegaRAID Storage Manager and is suitable for controllers from series 93xx on. I would install ESXi to the RAID 1 array and use the RAID 5 array as a second datastore. To check RAID type from the command line: Go to System Settings. The card does however have diagnostic LEDs with headers, so I suppose some sort of hardware hack might be a last resort.

I actually didn’t think RAID3 was a thing but I looked it up and sure enough… but it’s odd to me to use one drive to store parity info as that drive wouldn’t have redundancy. You’ll want to RAID those 3x 1TB drives in RAID 5 which will yield I believe it’s 2x write performance, 1x read performance with tolerance for up to 1 drive failing.
