Norco 4224

I'm running out of space in my Norco 4224 have 24 HHDs installed but I do have 3 or 4 drives still Blank in FlexRaid and another blank outside the case just in case of a disk failure. I have a few options I was going over.

A. I can start swapping old 1.5TB/2TB (currently have 8-1.5TB and 9-2 TB) disk for 4TB HDDs

B. I can start deleting data when I need more room which I do at times.

C. I add on with another server case only storing disk no MB/CPU

The correct answer for me is All of the above. How do I go about adding on another case. The best would be either get another Norco 4224 or build my own when it becomes that time, but for starters I will just reuse a old computer tower til I need more room that it hold which shouldn't be for 1+ yrs depending if HDDs die and get replaced for 4TBs some of those 1.5TB/2TBs are 4+ yrs and could crap out anytime. I just see no need to replace them til they finally fry.

From what I can tell I would need Case,PSU, and most likely another Chenbro SAS Expander if I plan on upgrading to that 2nd Norco 4224 in the future. And then a SFF-8088 cable running from Expander A to Expander B. Am I missing anything. Would there be a cheaper solution than buying a 2nd Chenbro SAS Expander by using some sort of SAS/SATA Port multiplier not PCIe though since the 2nd case won't have a MB.

Lastly I know my FlexRaid is pretty slow mostly because of those 1.5TB/2TB drives are WD Green's. Would I benefit at all by replacing my HBA Supermicro - AOC-SAS2LP-MV8 to a Raid Controller would that speeds things up at all. Just was wondering what kind of a performance boost I would see if any if I did. I know during my last Parity Build I maxed at only 18 MB/s and slowly dropped out each %. If so any suggestions ?

I do plan on either upgrading my main rig i7-920 or the Server with the i3-530 and dropping the i7 setup in the server or get Broadwell or Skylake CPU when released for either the server or main rig.
 
If your current box is maxed out, then you have no other option than to build another box.

If your concerns are on having a single point of access to that data, remember that RAID-F and RAID and pool network shares.

Don't over tax a single system. Too many disks under a single array is not a good thing.
