Online volume expansion
Managed from DiskStation Manager on the host NAS, the additional bays in the DX517 are immediately ready to be used once connected. On-the-fly volume expansion ensures that storage and services on the host are not interrupted during volume expansion.
Hot-swappable drive tray design

This is called your duty free allowance and personal goods concession. It is important to review these for any purchases you make on The Mall.
Your duty free allowance entitles you to bring into New Zealand the following quantities of alcohol products free of customs duty and GST provided you are over 17 years of age. You do need to be 18 years or over to purchase.

When travelling overseas there are legal limits on the amount of duty free alcohol and other goods you can take with you. These amounts will vary depending on the country you are flying into. We always recommend you check the latest limits and exemptions.
