Onboard sata vs onboard sas

[Journer]

I'm planning to purchase a motherboard that has onboard Sata 6g from intel soc, but it also has lsi3009 sas12g hba for 8 more drives

I'm planning on purchasing WD red Sata 5400rpm Sata drives.

In general is it better to use Sata drives on sata built in or to use the sas hba instead?

I'm thinking to populate the 6 sata ports now then potentially add a new pool of 8 drives or maybe ssds on the sas12 in the future

If it's better to use the sas hba, I might just buy some seagate sas12 7200rpm drives instead

In general, I'd say it doesn't matter--those drives aren't going to come close to maxing out the SATA ports, much less the SAS ports.

Nice thing about the SAS controller is it can use SAS expanders to add even more drives. And you can neatly pass it into a vm.

Thanks!

I was thinking of running esxi and freenas in a vm with pass through.

Is it hard to pass the soc sata ports/hba through??
