we have a couple of Servers available R630, R730s with E5-2699v4 dual cpus.. we are planning to make some testing on a BGP solution with routerOS v7.. we have already the 100G network cards available and compatible..
now before we go ahead and buy the L6 licenses.. we are searching for a best option market for reliabilty..
we have doubts.. shall we setup 5 disks SAS 15K RPM in Raid5 mode? or shall we use SSD enterprise Dell model disks? or Nvme ?
which one would workout best? we will be running bare metal x86_64 .. not virtualization CHR
Use whichever actually work with ROS. I don’t know how is v7 support for storage, v6 was less than stellar in this regard.
I’m not running any kind of similar setup, so I don’t have 1st hand experience. But AFAIK ROS only uses permanent storage for own files, config and some limited amount of volatile data (some logs if configured do, some limited stats). So you really don’t need huge amount of fast storage … a plain old SATA spinning disk would probably do just fine. If you find out that (hardware) RAID 1 is supported, then go for it … only to protect your investment in ROS license.

May I ask why? We stopped doing this and run all CHRs in VMs. It is so much easier to maintain, and ROS x86_64 constantly lacks behind with support of HW, especially recent network cards. And it can easily be moved from one server to another.
On vmWare using vmxnet3 network drivers, we see almost no no performance difference from VM to baremetal.
