Disk configuration on HP Microserver Gen 8

[jamieyates79]

I've recently setup my UNRAID server on a Gen 8 HP Microserver. Specs below:

I hadn't realized but only two of the ports on the server are SATA 3 (6GBPS throughput) whereas the remaining two are SATA 2 (3GBPS). 

 

I currently have 3 x 3TB WD Red HDD's and a 500GB WD Red SSD as a cache.

 

• 3TB WD Red Parity disk
• 3TB WD Red Storage disk
• 3TB WD Red Storage disk
• 500GB WD Red Storage disk

 

I'm guessing that I'd be better off using the two SATA 3 ports for the cache and a storage disk, meaning the the other storage disk and parity drive will be on the slower SATA 2 ports. 

 

Can anyone advise on the best approach here? Help and guidance much appreciated

It doesn't matter for spinning rust, it would for SSDs.
