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 2030), ideal for businesses requiring matching NAS models deployed in long-term projects.
Dual-port 2.5GbE and single-port 10GbE connectivity. The dual 2.5GbE ports also support SMB Multichannel for up to 5 Gbps!
Connect TL-R1620Sep-RP / TL-R1220Sep-RP JBOD units to the TS-855X for adding up to 48 additional drive capacity to match your business growth.
Features two PCIe Gen 3 slots for installing 5/10/25GbE network cards, QM2 cards or Fibre Channel cards.
Dual M.2 PCIe NVMe slots enable SSD caching, SSD storage pools, or Qtier™ auto-tiered storage.
Host virtual machines and containerized apps on one device to optimize resource utilization and IT budgeting. Supports SR-IOV.
A reliable backup center for your PC/Macs, virtual machines, containers, cloud data, and SaaS data.
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.

Tested in QNAP Labs. Figures may vary by environment.
Test Environment:
NAS : with QXG-25G2SF-CX6
OS : QTS 5.0.1
Volume type : 8 x Samsung 860 EVO 1 TB SATA , RAID 5, thick volume
Client PC : Windows Server 2016 Standard, Intel i7-6700 3.4GHz, 64GB RAM
IOmeter : 16MB, 30-sec ramp up time, 3-min seq. run time, 16 workers, 4-outstanding
Common Fibre Channel Storage Area Networks (SAN) devices are often costly. By installing QNAP dual-port 16Gb / 32Gb Fibre Channel expansion cards in the TS-855X, you have more budget-friendly options to add a NAS to a SAN environment. You can set a Fibre Channel Target using the iSCSI & Fibre Channel app. Moreover, the LUN Masking and Port Binding features provide an additional layer of data security.
QNAP provides easy ways to expand your storage capacity. Here are several ways to expand your TS-855X storage as needed to accommodate data and business growth.
