Might also look at larger drives. When I compared 3.5’’ drives then the 24TB is cheaper per terabyte than both 16TB and 12TB. The ones I compared are listed below:
Seagate Exos X24 Harddisk ST24000NM002H 24TB 3.5" Serial Attached SCSI 2
Seagate Exos X24 Harddisk ST16000NM001H 16TB 3.5" Serial ATA-600 7200rpm
Seagate IronWolf Harddisk ST12000VN0008 12TB 3.5" SATA-600 7200rpm
Followup; Not as cheap but there are M.2 to SATA cards available too, if your mb has no empty PCIe but do have empty M.2 available.
