MP 1,1-5,1 Can I add a 14TB hard drive to a 2009 Mac Pro?

[pirateyarrr]

I have a 2.66 Quad-Core (early 2009) Mac Pro running High Sierra. Need more internal HD space and I'm looking at a Seagate Exos 14TB on Amazon. Does anyone have any experience with a large-capacity drive like this in a Mac Pro that's this old?

Sure you can.

Mac OS X Maximum Drive Capacity​

• OS X 10.0-10.1.5, 2 TB maximum volume size
• OS X 10.2-10.2.8, 8 TB
• OS X 10.3-10.3.9, 16 TB
• OS X 10.4 and later, around 8 exabytes (8 million terabytes!)

It's not so easy. Recent HDDs are partially incompatible with SATAII ports and have different layout for the mounting holes that is incompatible with Mac Pro sleds/caddys.

It's better to move this question to this thread:

MacPro 5.1 & high capacity hard drives

I've run out of internal storage on my MacPro 5.1. And although I have a 24 bay NAS in the background, I need more high speed storage. I would think my cheapest option would be to upgrade to larger disks, as I currently run 4x2TB in Raid0. Does anyone have experience running larger disk, such...

Sure, but I wasn't really worried about the OS maximums. It's more a question of, can the 2009 motherboard on my Mac Pro handle it? I don't know anything about chipsets and what size limitations on HDs are as far as Mac hardware goes.
