Just sharing knowledge.
I just upgraded my TS5400R with 4X 12TB drives. Seagate IronWolf Pro ST12000NE0007
I'm running them in Raid 10 without a problem.
But before i did the Raid 10, i tried Raid 0 and Raid 5 so that i could share the knowledge here.
They all worked just fine.

Hackmaxx, thanks so much for sharing that! You confirmed what I really needed to know. I'll probaby go with either 12TB or even 14TB drives and report back here.

Did you also upgrade the onboard RAM?

Dumb question: 4x 12tb drives in raid10 would be a ~24tb array, have you tried filling it up? My guess is that a 24tb xfs volume on a 64-bit kernel (even an older one like this) would work but Iíve never tested. I have run into a hard 16tb limit on 32bit systems (xfs and ext4) and even on 64bit systems with ext4.

Try filling it up with data and make sure you can actually write past the 16tb mark. Even on 64-bit systems the default for some filesystems is still a 32-bit address space (2^32 * 4k blocks = 16tb).

Its probably fine but you dont want to learn the hard way

I had tested to format a 24TB Raid5 (4x 8TB)
mdadm was able to start the array, but mkfs.xfs was not able to create the filesystem
(LS-QVL  Marvell 88F6282 ARM)

Hackmaxxx was able to do that.

I wish I had taken better notes when I did that testing. I remember some in some instances mkfs did fail but I think it did succeed for some filesystems.... or maybe mkfs would fail but growing the filesystem wouldnít throw any errors.

I do remember that mdadm had no problem creating the array but dd and other tools would fail writing aything past 16tb.

I always try to recommend testing you can write to an entire array before relying on it becuase these types of issues arenít always aparent right away.

Over the years Iíve run into 4 or 5 independent issues that resulted in drives/arrays that reported one size but could only be partially accessed ~2 of which were related to 16tb kernel/filesystem limits.

Joined this forum just to say thank you. been looking for a NAS that can support 8tb + drives. you guys rock.

I did not upgrade the ram. The NAS is only used for Acronis backup storage. Users don't connect to it for file transfers.
I did check the NAS logs and do not see any spikes in CPU or memory.

I did read about the 16tb limit, but was told by tech support that there is no such limit.
I thought it was worth the gamble to buy 4x 12tb drives for $2400 cad, then it was to have to buy another NAS for over $5000 cad.

Sorry to reopen this thread, but you guys seem to have a lot of experience upgrading these systems and I want to make use of that knowledge.

I have a TS5400R that came with 2TB drives, it is FULL and I want to upgrade.  This unit is being used as an ArcServe backup storage location and is configured in RAID 5 (YEA I KNOW.....) but since it is just backup storage I am comfortable with 5 since it gives me the most amount of storage with some redundancy.
I would like to keep the current backups and have them available on the new array, is it possible to replace the drives one at a time and then expand the array after all have been upgraded to 8TB drives? Or would it just make more sense to pull the current drives place in storage and reinstall if I ever needed to get something off them?

Hello garryschaffel,

I think your best bet would be to pull your data onto another drive then replace the drives in your NAS.
These boxes are not the fastest at rebuilding Raid arrays.
It will take a really long time for it to rebuild the array 4 times.

Sorry for renecroing an old thread, but I couldn't find much else on this topic.  I have a TS5800D with 8x3TB that's almost full.  My idea is to buy 4x16tb Exos drives (https://www.amazon.ca/gp/product/B07SPFPKF4/ref=ox_sc_act_title_1?smid=AECIPMEQNVKO2&psc=1) and then add more to the pool as I need more storage.  I'm a little worried that it might not work and a little unsure if you can add drives to the pool after creating a RAID.  Right now I'm in RAID 6 (with 2 drives of redundancy). 

Any thoughts on this?  Sorry if any of my terminology is wrong.  I'm not very deep in the learning curve about NAS.

Does anyone know if that chip is an ECC chip? If not, would the mainboard support an unbuffered ECC DDR3 SO-DIMM chip? Regardless, what is the maximum capacity allowed? mx player app

I've got some notes about ram upgrades for the TS5000 here:
https://buffalonas.miraheze.org/wiki/Terastation_TS5600DN#Device_Notes

I believe I read that 4GB is the max for this chipset. I seems pretty flexible regarding what DDR3 SODIMMs it will accept. I've had good luck on several devices with really cheap modules.
