Moreover, RAID 5 will provide you with more reliability as fault tolerance is depicted with distributed parity check.<br />
<br />
If you can provide for 4+ disks you can have high reliability with high performance using RAID 10, 50 or 0+1. RAID 50 will require at least 6 drives but has high I/O rates and data transfer performance.<br />

I have 3 VMs (on ProxMox).  Will I get better IO performance putting all 3 on a hardware RAID5 array or using a single drive for each VM?  I am using SATA drives not SAS.

Which is better for virtualization, RAID5 or Single drive?

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
