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. -dsr-
