vmware esxi - Raid 10 to SSD's or not?

I have R620 server. I have that disks:




  • 4x512GB Samsung SSD

  • 4x1TB Seagate ES.2 HDD



I will use Vmware Esxi to create virtual machines. What's the best option? Using SSD's as primary drives and use them at RAID10 or using HDD's with RAID10?




I will host 1200 websites on this server with cPanel.



Capacity is not my concern. But performance is. When I Raid 10 with SSD's, it doesn't really show 4x performance and 4K Seq. Read/Write rate is very low. So that makes me think using it.
