5800d max hard drive size?

[Fordtough68]

I have looked everywhere and I cam not find a definitive answer. I have (2) 5800dn nas thqt both came with (8) 4tb drives in each one. I am maxed out in storage and wanted to upgrade the drives.

What is the largest drive size that I can replace the current 4tb drives with?

Not sure if you found your answer, but I'll reply anyway for others that may have the same question.

I believe the 5000 series could handle pretty much any drive on the market today.  I'm not sure of the max size, but I can say I have 18tb drives running in a TS5400, and 14tb drives running in a TS5800 for a good year now, and no problems.  I plan on moving to 18s in a 5810DN, once I sort out my networking problems with it.

It's the 3000 series and older that are limited to 16tb RAID Arrays or 16tb disks max in JBOD mode.  You can't use 18tb or larger drives in those for sure.
