Model: SA3234C

Will this card work as a boot drive?
Yes - connect the OS drive to Port 1 and set AHCI first. Most UEFI boards boot fine; some older Legacy BIOS boards may not.
Can all four ports run at full SATA III speed?
One drive can. With four drives at once they share the PCIe 3.0 x2 link - about 1.6GB/s total (~415MB/s each).
Does it support hardware RAID?
No. Use software arrays: Windows Storage Spaces, ZFS, mdadm, unRAID, TrueNAS or Proxmox.
