Sure it does, it's just incredibly unsafe. What you're referring to is RAID 0, and running it with 9 drives is perfectly fine and will get you the single 18 TB array you're looking for. The problem is you're now 9 times more likely to lose a drive versus just having one drive by itself, and being RAID 0, if you lose that one drive, you lose the entire 18 TB array. The other RAID levels (5, 6, 10, etc) allow you to sacrifice some
of that 18 TB in exchange for redundancy to protect you from single or multiple hard drive failures.
