I'm not sure about this. Can someone explain how the RAID configuration affects the number of disks needed?

I agree with Tayna. With RAID 5 (8D+1P), each disk will contribute 600 GB of usable space.

Wait, wait, wait. What's this RAID 5 (8D+1P) business? I thought we were just counting disks, not playing Tetris with storage space. Let me break out my abacus and see... Ah, C) 140 is the closest answer. Easy peasy!

That makes sense. C) 140 is the closest answer without considering data protection space.

So, if we need 60 TB of storage space, we would need 140 disks with 600 GB each.

RAID 5 (8D+1P) means we need 8 data disks and 1 parity disk.

Hmm, let's see. If the customer needs 60 TB and is using 600 GB disks, that means we need around 100 disks, right? Gotta love those RAID 5 calculations!
