OK.
If your computer has sufficient physical space and SATA
interfaces, you can install 5 x 18TB or 5 x 20TB or however many
disks that you like, and use mdadm in linear or stripe mode, or
ZFS in stripe mode, or just mount them all as individual
volumes.
There is no data protection in any of these modes.
If you do not have enough SATA interfaces, but has a PCIe slot available,
you can use a SAS controller with, most usefully, an LSI 3008 interface
chip to plug in an external box. The useful variants of that card include
the 9300 4i4e and 9300 8e.
That card would connect to a storage enclosure which would hold
the drives and a power supply. They are typically available to
hold 4, 6, 8, and 12 3.5" disks.
Linux has built-in support for the 9300 series cards. If the
vendor offers you a choice of R mode or IT mode firmware, you
want the IT mode firmware -- it is more flexible, and easier to
use with mdadm and ZFS and such. The R mode implements a RAID
system directly.
