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.
