Recommended configuration for Storage Spacec 2012 R2

[frankive]

I will sonn receive my Supermicro 45-disk rack-enclosure with WD RED 4TB drivers.
It will be conneceted with a HP DL_360 G6 and a LSI Raid card (in non-raid mode..)

I want to use Storage Spaces and Windows Server 2012 R2.

Would you recommended parity or mirrored? I must admit I am leaning too mirrored because of the performance, rebuild time, at least in the tradiotional Raid-world.
What would you guys do? Mirrored or parity?

Hi Frank,
I'm not used to Storage Spaces, but if mirrored means raid10 and parity is the usual Raid5, I'll go anytime for Raid10. Parity has a huge performance impact on any storage, and it was really developed in the past to justify the price of hard disks and still guarantee some protection. On modern systems, the time required to rebuild a large parity-based raid is really too much in most scenario, sometimes leading to additional disk failures right because of the stress created by rebuilds.
If your budget allows for raid10 (50% of raw space will be available...) go for it, especially as the primary target of Veeam backups.

Luca.
