Hello, and welcome to the forums!
If I'm understanding correctly, you're asking about compatibility between the controller, and any possible hard disk drives. According to the product brief, the PERC H730 is compatible with SAS and SATA disks. The controller should support basically any drive that is SAS or SATA compatible. I don't foresee an issue related to compatibility.
As for recommendations on HDDs, I would say stick to the higher-end WD (also HGST) or Seagate disks. Now, I'm curious as to why you're saying you need SAS drives. If you do require SAS, we're talking (ideally) Seagate Exos 8TB (linked to Newegg
here). Alternatively, if you could use SATA disks, then I would say definitely check out the WD Gold 8TB HDD (linked to Newegg
here). I'm personally more of a fan of WD drives if you're looking for absolute reliability.
What kind of RAID array do you plan to implement? If you don't need all the space, and you're looking at having near-24/7 uptime, then RAID 10 is your best bet more than likely.
I hope this helps, and please reach out if you have any more questions!
