My raid drives consume 11w per disk at maximum load and i have more than 400w left on my power supply.

Thanks for the clarification

I will have the hba card so that will be ok, 5satas port is ok with an al-x motherboard, the problem might be the number of pci ports and the vt-d compatibility.

I think i misunderstood what you guys said about jbod (my fault for
reading quickly), i talked about the jbod feature, not a hardware piece.
My disks are sitting in my desktop, if i buy an external storage for the
disks i might as well build a nas, which is what i do not want, i'm
looking for internal connection not external.

was crawlking lsi and highpoint cards, cards between 200 to 300+$$, not
really what i call cheaper stuff that's aimed at Winblows users ;)

Putting 6 or 8 drives inside your chassis is really not a normal
situation. Are you sure your power supply can handle it? You also
mentioned somewhere that you have several GPUs and such. That would
tax your power supply even more. Remember, spinning drives eat a lot
of power when first "spun up".

I recommended a JBOD for the reason that it eliminates the need for
a gazillion SATA or SAS connectors on your motherboard, cleans up the
cabling and doesn't put a ridiculous load on your power supply. As to
building a NAS, you'd need a motherboard with the same number of
connectors, huge power supply, and all the drives to build your NAS and
yeah, it's a right pain to build. With the JBOD, you need the HBA (one
PCI slot), the JBOD and the drives and all of this is easily
transferable to your new system when the new motherboard you want comes
out. It'd be faster than a NAS as well as supporting native file
systems with all the ACLs, permissions and goodies (NFS and CIFS don't
support that well).

Regarding the new motherboard, will it have all the SATA/SAS connectors
you need to drive this array or are you going to be in the same boat as
you are now?
