Some primitive calcs: 5*18T = 90T, not 100T. Maybe you need 6 hdd?

If your hardware supports 6 hard drives (5*18T + your 2T), you can use
lvm for merging 5 of them to one volume, or create raid0 by mdadm.
Some risks with plain disk merging - if one of your drives die, entire
volume dies.
It may be mitigated by use raid5 with 1 additional drive or raid6 with
2 (see https://en.wikipedia.org/wiki/RAIDhttps://en.wikipedia.org/wiki/RAID)
