4 Things to Know About Expanding the Asustor AS6604T

You can add storage via an external USB enclosure or an Asustor expansion unit. Both connect through the AS6604T’s USB 3.2 Gen 2 ports.

The AS6604T offers more expansion options than smaller Asustor models. It supports USB-based expansion, which is a step up from limited models.

All expansion is USB-based — there is no PCIe or eSATA support. This means you cannot add internal expansion cards or use faster eSATA connections.

For most home users, USB 3.2 Gen 2 is fast enough for media storage and backups. But if you need low-latency or high-bandwidth expansion, this NAS may not suit you.
