If your storage box stops working, start with the business that sold it to you and have your purchase record ready. A NAS, or network-attached storage device, connects to your network so multiple devices can use the same files and backups, much like a shared filing cabinet.
In short: Contact the retailer first. Check the warranty against the exact NAS model, because cover can vary within one maker's range, and check each installed hard drive's own warranty with its maker.
Two different protections: the maker's warranty and your consumer rights
A maker's warranty is the manufacturer's published promise about its hardware, including how long the stated coverage runs. Your rights under consumer law are a separate thing, and Australia's consumer regulator explains them.
Your first step for a faulty product is usually the retailer that sold it. The ACCC explains your rights under the Australian Consumer Law at accc.gov.au.
Who to contact first
Start with the retailer shown on your receipt or order confirmation. Think of the retailer as the shop counter you return to, even when the maker also operates a support portal.
Tell the retailer the model, serial number, purchase date and symptoms. Follow its return instructions before sending anything, because the required contact and shipping process can depend on where and how the NAS was purchased.
Warranty length by maker
Need to Know IT read each maker's published warranty terms on 21 October 2026. These are the hardware warranty periods each maker publishes.
| Published NAS warranty length | |
|---|---|
| Synology | Set per model. The status table listed the DS225+, DS425+, DS925+, DS1525+ and DS1825+ at 3 years, and the DS423 and DS223j at 2 years. The five listed Plus models offer an optional 2-year extension in select regions. |
| QNAP | No single standard length. Each model's specifications give the period. The TS-264, TS-464 and TS-h973AX each listed a 3-year standard warranty. An extension can take coverage up to 5 years when registration occurs within 9 months. Bundled accessories have a 1-year warranty. |
| ASUSTOR | Per model, from three months to five years. Check the product's specifications or support page. ASUSTOR says repair requests should start with the place of purchase. |
| UGREEN | DH and DX series: 2 years. DXP series, including the maker's DXP2800, DXP4800, DXP4800 Plus and DXP480T Plus examples: 2 years. DXP6800 and DXP8800 series: 3 years. Power adapters and network cables: 1 year. |
| TerraMaster | 24 months from the retail purchase date unless the product's owner's guide states another period. Need to Know IT did not find Australia-specific wording on this page. |
Sources, as read on 21 October 2026: Synology: Status table and DS225+ example; QNAP: Policy, TS-264, TS-464 and TS-h973AX; ASUSTOR: Warranty page; UGREEN: Australian warranty terms; TerraMaster: Warranty and returns.
Need to Know IT's maker guides cover each range in more detail: Synology, QNAP, ASUSTOR, UGREEN and TerraMaster.
Do not infer the warranty of an unlisted model from a nearby model number. Check the exact product specifications or support page, particularly for QNAP, ASUSTOR and TerraMaster models.
Hard drives have their own warranty
The NAS and the drives inside it can carry separate warranties. ASUSTOR says it does not warrant installed hard drives or SSDs, while UGREEN says hard disks follow the drive manufacturer's warranty.
Western Digital publishes a 5-year limited warranty for WD Red Pro and a 3-year limited warranty for WD Red Plus, with regional details to be checked. Seagate publishes 3 years for IronWolf and 5 years for IronWolf Pro, while also directing buyers to the applicable period on the product packaging. Check the exact drive label, receipt and maker lookup rather than relying only on the NAS receipt.
The NAS hard-drive guide explains the drive families. Warranty replacement is also different from professional NAS data recovery.
Before you send a NAS in
A warranty repair covers the hardware, not your files. Back up accessible data first using a plan such as the 3-2-1 backup strategy, because sending hardware away is not a data-recovery service.
Keep the receipt and serial number. Record the installed drive order, photograph the setup and follow the return instructions you receive, including what parts and accessories should be sent.
Buying from overseas or a marketplace
Buying from overseas or a marketplace seller can change who you deal with. Read the seller's warranty and return terms, identify the business named on the order, and read the ACCC page linked above.

Who do I contact if my NAS dies under warranty?
Contact the retailer or seller shown on your receipt first. Give it the exact model, serial number, purchase date and a clear description of the fault, then wait for return instructions before shipping the unit. If the maker or seller operates a support portal, the retailer may ask you to open a case there as part of its process.
Does the NAS warranty cover the hard drives inside it?
Do not assume it does. The NAS and its drives can carry separate warranties, and ASUSTOR and UGREEN explicitly direct drive coverage to the drive maker. Check each drive's model and serial number with its manufacturer, then keep the drive purchase record alongside the NAS receipt.
Will a warranty repair recover my data?
No. A hardware warranty process is not a data-recovery service, and the returned unit or drives may not preserve your files. Keep an independent backup before a failure occurs and copy any still-accessible data before returning hardware. If the only copy is on failed storage, assess recovery separately before sending it away.
How do I find my exact model's warranty length?
Read the model number from the chassis label or purchase record, then use that maker's product specifications, support page or warranty lookup. Do not apply one model's period across an entire brand. Synology and QNAP publish model-level information, while ASUSTOR directs buyers to each product's specifications or support page.
What should I keep when I buy a NAS?
Keep the receipt or invoice, NAS serial number, exact model name and order confirmation. Store the same information for every hard drive, because its warranty is separate. It is also useful to record which drive occupied each bay and retain any support case numbers and return instructions.
A warranty repair covers the hardware, not your files. Set up a backup that would survive the NAS going away for repair.
