QNAP TS-855X 8 Bay Diskless Desktop NAS Enclosure

High-performance 8-core 10GbE NAS for deploying hybrid-infrastructure storage and high-speed virtualization applications

The high-capacity TS-855X has six 3.5-inch SATA drive bays (for HDDs), two 2.5-inch SATA drive bays (for SSDs) and an 8-core processor supporting Intel® QuickAssist Technology (QAT), greatly assisting businesses in deploying a data storage and virtualization environment. The built-in 10GbE/2.5GbE high-speed connectivity helps realize fast data access, backup/restoration, file server, and virtualization applications. Running the QTS operating system as standard, the TS-855X can be switched to use the ZFS-based QuTS hero operating system based on your requirements. The TS-855X will be available and supported by QNAP for an extended period (up to 2027), ideal for businesses requiring matching NAS models deployed in long-term projects.

Ultimate 8-core performance with up to 128 GB RAM and Intel® QuickAssist Technology
The TS-855X delivers exceptional 8-core performance for running multiple concurrent tasks. AES-NI encryption and Intel® QuickAssist Technology (QAT) are supported to offload resource-demanding compression and improving IPsec/SSL cryptography performance. The TS-855X comes with four UDIMM DDR4 slots (8 GB preinstalled) that can be upgraded to 128 GB ECC RAM for higher workloads. Combining high performance, reliability, and capacity, the TS-855X is an all-round budget-friendly storage solution for diverse applications, such as file servers, high-speed storage/backup/recovery, and virtualization.

Build a High-Speed 10GbE/2.5GbE Network Environment
Featuring two native 2.5GbE RJ45 (2.5G/1G/100M) LAN ports and a 10GBASE-T (2.5G/1G/100M) port, the TS-855X satisfies bandwidth and reliability demanding business applications including virtualization, large file transfers, high-speed backup/restoration, and real-time applications. Combine the dual 2.5GbE ports with SMB 3.0 Multichannel for up to 5 Gbps fault-tolerant connections! QNAP also offers numerous managed/unmanaged 2.5GbE/10GbE switches, assisting organizations in implementing high-speed, secure, and scalable network environments without going over budget.

M.2 PCIe slots for SSD caching and accelerated AI-powered image recognition

SSD caching
Configure SSD caching with M.2 SSDs and obtain optimal I/O and reduced latency without occupying any 3.5-inch drive bays.

Auto Tiering
Qtier™ technology empowers the TS-855X with auto tiering to continuously optimize storage efficiency across all installed storage devices.

Faster image recognition with Edge TPU
Coral M.2 Accelerator with Edge TPU provides an affordable solution to leverage AI acceleration for faster image recognition in your NAS applications.

Upgrade to 25GbE network with PCIe expandability
The TS-855X has two PCIe Gen 3 x4 slots that allow for installing various expansion cards to increase its application potential.

Simple Backup
Superior hardware performance with an all-in-one Backup Solution to speed up backup/recovery tasks.

PC and Mac backup
Sync your computer files to NAS with Qsync. TS-855X also supports Time Machine for Mac computers.

License-free VM backup
Back up multiple VMware® and Hyper-V™ VMs using Hyper Data Protector.

File server backup
Supports multiple protocols such as Rsync, FTP and CIFS for backing up different file servers.

SaaS Business Backup Solution
Use Boxafe to easily back up Google™ Workspace and Microsoft 365® business account data.

Google Photos and WordPress backup
The exclusive MARS service enables backing up Google Photos and WordPress databases and files to NAS.

Multi-version snapshots mitigate ransomware threats
The TS-855X supports block-based snapshots that record the state of the system at any time. It helps protect data, which can be restored back to a specific point of time, greatly helping in mitigating the threat of ransomware.

Volume and LUN snapshots
Take snapshots in seconds and revert the entire volume/LUN back to a specific point in time to prevent loss of important data.

Instantly restore snapshots
Snapshot content can be quickly restored to a local NAS, or restored on a folder/file basis to a local/remote NAS or cloud storage. You can also conveniently view and restore snapshots from the client side.

Back up snapshots
Multiply data protection by backing up snapshot files! Replicate volume/LUN snapshots in the TS-855X to a remote NAS (Snapshot Replica) by copying only the changes made. This helps save time & bandwidth, and can be run manually or on a scheduled basis.

Reliable, high-performance storage for virtualization
The TS-855X supports block-based iSCSI LUN as a reliable, high-performance, and affordable storage solution for mainstream virtualization environments. It supports VMware® VAAI and Microsoft® ODX to increase performance by offloading server loading for ESXi server and Hyper-V respectively.

All-in-one solution for hosting virtual machines and containers
By running multiple virtual machines and containers on the TS-855X, you can deploy multi-tenant environments and applications to increase management efficiency and save hardware costs. Coupled with the Network & Virtual Switch app that boosts interoperability between virtual machines, containers, QNAP NAS, and other physical devices on the network, you can flexibly allocate physical and virtual network resources to simplify network deployment.

Virtualization Station
Run multiple Windows®, Linux®, UNIX®, Android™, and QuTScloud virtual machines and access them via a web browser or Virtual Network Computing (VNC). Businesses can run virtualized server applications on a single NAS with
