Buffalo TeraStation TS5400R Hard Drive Capacity Support

Let us know what happens!

Yep yep. Just updated the thread :)

Nice, are you using RAID at all? I'm guessing it should handle really big volumes fine in that configuration. Just curious because the 32-bit devices run into a 16TB volume limit which should not apply as far as I know.

Glad to see this thread has had a following with lots of responses. I've been successfully running three of these for the past few years.

Device 1 is running 4x8TB WD Red NAS drives 5400rpm in RAID 10
Devices 2 and 3 are running 4x14TB WD Red Pro NAS drives 7200rpm in RAID 10


Devices 2 and 3 are nearly at capacity so I'm finally shutting all down and moving to a giant 12-bay Buffalo Terastation 51210RH 2U device with possibly up to 16GB ECC DDR3 UDIMMs, 12x14TB enterprise grade HDDs 7200RPM and plan on running RAID 6.

I'll keep these Terastations because I've had nothing but success with them. Of course they sit in a server room with active cooling that stays below 65 degrees F year round.

Fantastic devices.

Very happy you like them :)

Well, her we go again.

After my initial upgrade/experiment on my TS5400R to 4x 12TB back in Jan. 2019, i can confirm that i surpassed 16TB of storage.
My current 4x 12TB system has a formatted capacity of 22287.1Gb with RAID 10, and I am at a little over 21TB used.

I am going to upgrade to 4x 20TB WD RED PRO drives in a RAID 10 again for a total of 40TB of storage.

The old 4x12TB will not be going to waste.
They are going to upgrade my Off-premise TS5400R in a RAID 0 to get me 48TB of storage.
Yes i know that a RAID 0 is not safe, but it is only there to be the secondary backup to my main RAID 10 backup.

I am also upgrading the memory of both TS5400R to 4GB.
Thank you Sid8tive for that info.

It may take a little while before i get this done, but i will post the resulting success.....or failure of this upgrade.

Success,

My TS5400R is running 4x 20TB drives in a Raid 10 for a total of 37TB of storage.

It was not as straight forward as i had hoped it would go.

After breaking the existing Raid (4x 12TB), I dismouted drive 4 and installed a 20TB drive
I tried to get the NAS to rediscover it but it just gave me the error.
I then used GPARTED LIVE to create a GPT partition table and installed it again. It just gave me another error.

Here is what worked.
Using GPARTED LIVE I created the GPT Partition table and copied the first 5 partions from my old 12TB drive to the new 20TB.
This left 18.17TB of unallocated space.
installed the new drive into slot 4 and did a REDISCOVER DISK.
The NAS showed the drive as unformatted.
Formatted the drive and got 18593.1GB capacity.

I did the same thing for the other 3 drives and all was good so far.

I guess from here you could create any Raid system you want, but i used Raid 10 and ended up with 37188.3GB.

The Array is functional but the Syncing is taking forever. Only 26% complete in 48 hours.

Hopefully the memory upgrade will speed it up, once it arrives.

You can usually speed up resync by bumping up the speed limit by modifying:

Code Select Expand

/proc/sys/dev/raid/speed_limit_max

Do you have a "How-To" on how to get in and change this?

Thanks

You can most likely send the relevant commands via acp_commander

Thanks for posting your experience, Hackmaxxx!

I got the TS51210R 12-bay 3U rackmount unit up and running. It has two DDR3 DIMM slots with only one 8GB module populated, so it was easy to replace with two identical Crucial 8GB ECC modules.

The main CPU has one heatsink, which I repasted, but there are two Aquantia 10GB chips that are non-heatsinked and get quite warm.

I was able to successfully install 12x 14TB drives with no problems and am running RAID 6. The syncing does take a while but not as long as on the TS5400R units.

One note, the unit, even with the latest version version of 5.80 cannot support some of the latest SSL certificates with over 2048-bit encryption. The web interface says accepted but them the UI becomes completely unreachable and unresponsive and you have to flash firmware from the web-based tool to reset everything, even the pin holding the reset button won't fix the SSL issue.  So no more SSL access to the web interface.

The only other problem is, the onboard fans do not spin fast enough and the drives run hot. I wish you could control the fan speed from the settings, because I would totally opt to run them at 100% if possible.
