BUFFALO TS5420DN2402 – TeraStation 5020 24TB 4-Bay 10GbE Desktop NAS
Overview
The BUFFALO TS5420DN2402 is a TeraStation 5020 Series 4-bay desktop NAS configured with two 12TB NAS-grade CMR hard drives for 24TB of installed raw storage. Two drive bays remain available for future expansion. The system combines 10GbE networking, 8GB DDR4 memory, software RAID, snapshots, replication, and centralized file services for business and departmental storage environments.
Technical Information
The TS5420DN2402 uses an Annapurna Labs Alpine AL524 2.04GHz quad-core processor with 8GB DDR4 memory. The installed two-drive configuration ships in RAID 1, providing 12TB of effective storage. The platform supports RAID 0, 1, 5, 6, 10, and JBOD configurations.
The TeraStation 5020 platform supports snapshots, abnormal file activity detection, remote configuration, hot swapping, hot spares, replication, failover, cloud integration, Active Directory, and iSCSI. The TS5420DN platform does not support SSD caching.
Compatibility
The TS5420DN2402 uses 3.5-inch NAS-grade CMR HDDs with SATA III 6Gbps interfaces. Buffalo lists the OP-HDN and OP-HDHU2 series as compatible HDD families for the TS5420DN platform.
Network connectivity consists of one 10GBASE-T RJ-45 port and two 1000BASE-T RJ-45 ports. The 10GbE interface supports 10Gbps, 5Gbps, 2.5Gbps, 1Gbps, and 100Mbps operation. Supported network file services include CIFS/SMB, AFP, FTP/FTPS/SFTP, and NFS.
Key Features
- 24TB installed capacity using two 12TB NAS-grade CMR HDDs
- 4-bay desktop chassis with two available drive bays
- 1 x 10GBASE-T and 2 x 1000BASE-T RJ-45 network ports
- 8GB DDR4 memory with Annapurna Labs AL524 2.04GHz quad-core processor
- RAID 0/1/5/6/10/JBOD with RAID 1 used for the installed two-drive configuration
Applications
The TS5420DN2402 is suited to centralized business file storage, departmental shared storage, network backup, replication, and data protection. The two unpopulated drive bays also provide a path for additional storage capacity as requirements increase.
