What this NAS delivers

The Buffalo LinkStation 720 is a two-bay desktop NAS that ships with two 2 TB drives for 4 TB total capacity. A hexa-core 1.3 GHz processor and 2 GB of memory run the closed-system firmware. One native 2.5GbE port and three USB ports provide wired and direct-attached connectivity.

Who it suits and who it does not

Small offices and home users wanting subscription-free personal cloud storage with RAID 0, 1 or JBOD redundancy will find it straightforward. Buyers who need more than two drive bays, 10GbE networking, expandable memory or third-party application support should look elsewhere.

What the included drives and ports change

The pre-installed 2 TB drives arrive ready for immediate RAID setup, removing the purchase and installation step. Two USB 3.2 Gen 1 ports and one USB 2.0 port allow direct attachment of external drives or a printer for network sharing without extra adapters.

Questions about this item

Do I need a router or switch with a 2.5GbE port to use the native 2.5GbE port on this NAS?

The NAS includes a single 2.5GbE RJ-45 port that also supports 1000BASE-T and 100BASE-TX, so it will work with existing Gigabit or Fast Ethernet switches, but you need a 2.5GbE-capable switch or router to reach the higher link speed.

Can I connect my existing USB 2.0 external hard drives to the USB 2.0 port on this unit?

Yes, the rear panel provides one USB 2.0 port alongside two USB 3.2 Gen 1 ports, so legacy USB 2.0 drives will operate at their native speed when plugged in.

How can I verify the two included 2TB drives are configured in RAID 1 after initial setup?

Log into the web management console; the RAID status screen will show the array type as RAID 1 and report the usable capacity as approximately 2TB with both drives healthy.
