QNAP TS-855X-8G 8-Bay NAS Server, Intel Atom C5125, 8GB RAM, 10GbE

The TS-855X-8G offers eight drive bays split between six 3.5-inch and two 2.5-inch slots. This layout lets you fill the larger bays with high-capacity hard drives for bulk storage while dedicating the 2.5-inch bays to smaller drives for separate volumes. Having eight bays in one enclosure gives room to grow a storage pool over time instead of replacing the whole system when space runs out.

At the heart of the NAS is the Intel Atom C5125, an eight-core processor running at 2.8 GHz. Multiple cores help the system handle several tasks at once, such as serving files to many users, running scheduled backups and processing data transfers in parallel. For a small business or a busy home lab, this means the NAS can manage simultaneous workloads without one job holding up the rest.

The unit ships with 8 GB of RAM, giving the operating system and installed services space to work with. More memory helps when several users access shared folders at the same time or when background tasks run alongside everyday file serving. The manufacturer does not specify the maximum supported memory in the data provided here, so check QNAP's official documentation before planning a memory upgrade.

Connectivity is a strong point of this NAS. A 10GBASE-T port supports 10 Gigabit Ethernet for high-speed links to a compatible switch or workstation, while two 2.5 Gigabit Ethernet ports support 2.5G, 1G, 100M and 10M speeds. This combination lets you connect to both newer multi-gig networks and older gigabit infrastructure, making it practical for editing large media files or running fast backups.

Three USB 3.2 Gen 1 ports and one USB 2.0 port provide plenty of options for attaching external storage. You can connect USB drives to copy data onto the NAS, create offline backup copies or expand capacity for archive purposes. The extra USB 2.0 port is suited to lower-bandwidth accessories, leaving the faster ports free for storage devices.

The TS-855X-8G uses a tower chassis and weighs 8.5 kg. Cooling is handled by two 80 mm 12VDC system fans and a 90 mm 12VDC CPU fan, helping keep drives and the processor at stable temperatures during continuous operation. A 250W power supply with a 100–240V input range powers the system, so it works with standard mains electricity.

This NAS suits small and medium-sized businesses, creative teams and advanced home users who need large shared storage with fast network access. Its eight bays, multi-core processor and 10GbE port make it a fit for media libraries, team file sharing and centralised backup of multiple computers. Users already running multi-gig networking will get the most from its connectivity.
