BUFFALO TS5420DN1604 – TeraStation 5420 16TB 4-Bay 10GbE Desktop NAS
Overview
The BUFFALO TS5420DN1604 is a TeraStation 5420 Series 4-bay desktop NAS configured with four 4TB NAS-dedicated HDDs for 16TB of total installed raw capacity. It provides 10GbE connectivity, 8GB DDR4 ECC memory, software RAID, and iSCSI target functionality for business file sharing, backup, centralized storage, and network storage deployments.
Technical Information
The TS5420DN1604 uses an Annapurna Labs Alpine AL524 2.0GHz quad-core 64-bit processor with 8GB DDR4 ECC memory. Its software RAID supports RAID 0, 1, 5, 6, and 10, as well as JBOD individual-disk operation. RAID 6 is the factory configuration, providing 8TB of effective capacity from the 16TB installed raw storage.
The system includes a hardware RAID accelerator for parity calculations used by RAID 5 and RAID 6. Data-management functions include snapshots, immutable snapshots, copy-on-write, metadata duplication, scheduled and snapshot backup, replication, failover, abnormal file activity detection and protection, iSCSI volume backup, remote configuration through KikiNavi, cloud-storage integration, Active Directory integration, and two-factor authentication.
Compatibility
The TS5420DN1604 uses four 3.5-inch NAS-dedicated HDDs with Serial ATA III interfaces supporting up to 6Gbps. Buffalo lists the OP-HDN and OP-HDHU2 series as compatible replacement HDD families. SSD caching is not supported on this model.
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, while the 1GbE ports support 1000Mbps, 100Mbps, and 10Mbps. Network file services include SMB/CIFS, AFP, FTP, SFTP, NFS, HTTP/HTTPS, SNMP, iSCSI, and rsync.
Key Features
- 16TB installed capacity using four 4TB NAS-dedicated HDDs
- 4-bay desktop chassis with 3.5-inch SATA III drive bays
- 1 x 10GbE and 2 x 1GbE RJ-45 network ports
- 8GB DDR4 ECC memory with Annapurna Labs AL524 quad-core processor
- RAID 0/1/5/6/10/JBOD with RAID 6 configured at shipment
Applications
The TS5420DN1604 is suited to centralized business file storage, client and server backup, departmental shared storage, replication, and virtualized environments using iSCSI. Its 10GbE interface also supports deployment in high-speed Ethernet networks where the NAS requires more bandwidth than a standard 1GbE connection.
DC Supplies Product Note
The exact TS5420DN1604 configuration contains four 4TB NAS-dedicated HDDs for 16TB of raw installed capacity. Buffalo specifies RAID 6 as the shipment configuration, with 8TB effective capacity in RAID 6. SSD caching and redundant power are not supported on this model.
