How much storage (TB is the maximum for an HP Z$ G$ with Xeon W-2123 or Xeon W-2133?

[The_VAudio_Guy]

Hi all. I am trying to find out the possible largest size of HDD storage I can use on the HP Z4 G4. I have the potential to buy one on which I want to create a windows storage pool using all 6 of the SATA ports on the board and the largest size NAS drives I can get into it. I have read through the documents on the site and some forums and have come across information saying there is a TB limit on the SATA controller (Some say 24TB, others say 32TB). 

Is it possible to exceed these limits using the onboard SATA connectors, or would I have to get a third party HBA controller to add essentially unlimited storage (drive size dependent)?

Thanks

there is no practical limit on the storage capacity with newer systems like your model,  both the hardware and the os support drive sizes that currently don't exist for single drive ( and multi drive configurations using software or hardware based raid)

You can use MBR or GPT for arrays smaller than 2.2 TB  if larger than 2.2TB then GPT must be used

previous models such as the z820 and earlier had a bios limit on the size of a bootable drive that was between 2gig/2.75

however even these earlier systems had no issues with larger capacity drives as non bootable storage using 6/8 TB drives

same for dedicated raid cards, current models will support large capacity configurations however unless you require the few specific advantages of hardware, a software based raid such as "zfs" is recommended for most cases nowadays
