Performance, Security, and Scalability

The Perfect 10GbE Entry Point for SMBs

The TeraStation 5020 is Buffalo’s flagship network attached storage (NAS) product, purpose-built as a secure, high-performance storage solution optimized for high workloads. Available in desktop and rackmount form factors, the TS5020 comes with high capacities in partial- or full populated models with NAS-grade hard drives included, allowing you to fulfill your data needs now while leaving the option to expand later.

Premium grade hardware components (hard drives included), with partially-populated options for additional flexibility. Hard drives included (enterprise-grade hard drives for TS51220RH models) and RAID pre-configured for Day One Ready NAS for streamlined deployment and out-of-the-box data protection. Buffalo Enhanced Security Suite for built-in enterprise-level data security without licensing or subscription fees, including low-exposure architecture and real-time threat detection. Data immutability for near-instantaneous data backup/restoration and ransomware mitigation. Cloud integration with Amazon S3, Dropbox, and Microsoft Azure and OneDrive for flexibility and security. Fast Ethernet ready with native 10GbE port for increased data transfers. VMware and Hyper-V certified (iSCSI & NFS certifications) for virtualization solutions, including iSCSI backup support. Made in Japan/TAA compliant.

Buffalo Enhanced Security Suite

Our TeraStation storage solutions are the only NAS built from a foundation of security, which is why they are the most secure NAS on the market.

The Buffalo Enhanced Security Suite is a built-in set of enterprise-level data security features to protect your data at the core. TS5020 runs on a Low-Exposure Architecture where even administrators lack root access, blocking unauthorized system changes.

Immutable Storage for Next-Level Data Protection

Protect your data from ransomware and accidental deletion with the built-in immutable snapshot feature.

Immutable storage ensures that data cannot be altered or deleted once written, providing next-level data protection for regulatory compliance, near-instantaneous data backup and restoration, and business continuity.

Proactive Ransomware Protection with Real-Time Threat Detection

Stay one step ahead of cyberthreats with the real-time threat detection feature, which actively identifies and notifies you of unusual file activity that could signal a potential ransomware attack:

File Count/Size/Extension Change Detection: Receive notifications if the number of files, the total size of files, or any file extensions are suddenly changed in a folder

Login Attempt Monitoring: Receive notifications if there are multiple failed login attempts, with the option to automatically block suspicious users or IP addresses after multiple login failures to reduce the risk of brute force attacks.

Fast Transfer Speeds with Native 10GbE

Multi-gigabit Ethernet can increase network performance to enable faster data transfer speeds. The TeraStation 5020 NAS with a native 10GbE port is perfect for those who are ready to commit to high-level, multi-gigabit data transfers. By using the same Cat5e cables that are already widely-installed around the office, you can enjoy notably faster network speeds within your network environment at much lower costs.

Certified Storage for Virtualization

Leverage the benefits of virtualization with the TeraStation 5020. Certified for VMware and Microsoft Hyper-V, the TeraStation can back up your virtual environments with a highly-reliable storage solution.

Enable fast deployment and integration into Microsoft and VMware virtual environments, and improve working efficiency with increased virtual application performance and greater flexibility in storage capacity planning and allocation, You can also back up virtual machines to the TeraStation to protect your environment from hardware failure.

Boost Performance with SSD Caching (TS51220RH Only)

SSD caching is a simple and powerful add-on option for the TS51220RH to boost high random data access. With an additional SSD (sold separately) installed, you can enhance your TS51220RH performance by up to 91%, greatly benefiting IOPS-demanding NAS applications such as databases, file servers, and virtual machines.

If you need additional IOPS, the TeraStation71210RH with SSD caching offers up to five times the performance for the most powerful Buffalo NAS experience.
