SP-64 2014 OVH

Hi,

I'm looking plan SP-64 2014 with 3x2 TB SATA3 LSI 9271-4i CacheVault 1 GB (RAID1 or RAID 5). I install Virtualizor KVM for VPS Node. Really i don't know much about HW Raid. It have BBU and will have high performance I/O with RAID1 or RAID 5. And what type cache i should enable for VM? Can you give me advice?

Regards,
