QNAP TS-831XU-RP 8-bay rackmount NAS with 24TB on six 4TB WD Red drives, for 10GbE file and backup storage.
This refurbished QNAP TS-831XU-RP is an 8-bay rackmount NAS, supplied under our SKU NAS-QNAP-831XU-24TB-6x4TB with six 4TB WD Red NAS drives fitted for 24TB of raw capacity and two bays left empty. It runs QNAP's QTS operating system, connects to the network through two 10GbE SFP+ ports and has redundant power supplies, so the loss of one supply does not take the storage offline. Buyers in Qatar usually take it as a central file server, a backup repository, an iSCSI or NFS datastore for a small virtualisation cluster, or a CCTV archive. Because it arrives already populated with matched NAS drives, a Doha IT team can build a RAID volume on the day it is racked instead of sourcing disks separately.
NAS-QNAP-831XU-24TB-6x4TBWill it fit my system?
For the empty bays, use 3.5 inch SATA drives rated for NAS duty. Within one RAID array, match the existing 4TB capacity; a larger drive works but only 4TB of it is used. Mixing drive models in one array is allowed, but keeping the same WD Red line makes performance and rebuild times predictable. On the network side, the ports are standard SFP+ cages.
| Item | What fits | Note |
|---|---|---|
| Drives | 3.5 inch SATA NAS drives | Match 4TB capacity within an array |
| Network modules | 10GbE SFP+ transceivers | SR optics for multimode fibre are typical |
| Network cables | SFP+ direct attach copper | Suits short runs to a switch in the same rack |
| Storage clients | Windows, Linux, VMware hosts | Over SMB, NFS or iSCSI |
Full configuration
The 24TB figure is raw capacity across the six fitted drives. Usable space depends on the RAID level you choose, and QTS reports capacity in binary units, so the formatted figure always reads lower than the drive labels.
What this configuration suits
Compare the workload you have in mind against the fitted components.
With six 4TB drives, RAID 5 gives about 20TB usable with one drive of fault tolerance, RAID 6 gives about 16TB with two, and RAID 10 gives about 12TB with better random performance. For backup and CCTV retention, RAID 6 is the sensible default because rebuilds on 4TB drives take many hours.
The two 10GbE SFP+ ports suit a server room with an SFP+ switch, where several hosts or backup jobs hit the NAS at once. They can also be used for separate storage and user networks, or connected directly to a host for iSCSI.
Six spinning NAS drives handle sequential backup and video streams comfortably but will not match SSD storage for busy virtual machines or databases. Treat it as capacity storage, not a primary datastore for latency-sensitive workloads.
Upgrade paths
- Two empty bays: add two more 4TB drives to bring raw capacity to 32TB, either expanding the existing array or creating a second volume.
- QTS supports online RAID capacity expansion and RAID level migration, so a RAID 5 set can grow or move to RAID 6 without rebuilding from scratch.
- Capacity can also be raised by replacing drives with larger ones one at a time, letting the array rebuild after each swap.
- The SFP+ ports accept either fibre transceivers or direct attach copper cables, so cabling can change as your switch infrastructure changes.

Enterprise hardware, tested in Doha, at a fraction of the price of new
Every unit we sell has already proven itself in a data centre. We test it again, grade it, and back it with a warranty before it leaves our stock.
Tested before it ships
POST, burn-in, memory and power-supply checks on every unit. Anything that fails is repaired or pulled from stock, not sold.
