The T6-423 6-Bay NAS Enclosure from TerraMaster is suitable for SMB users who need high-performance storage solutions. It is powered by a 2.0 GHz Intel Celeron 4-Core processor, 4GB of DDR4 RAM (upgradeable to 32GB), integrated Intel UHD graphics, and AES-NI hardware encryption. It runs using TOS, a Linux-based operating system. This unit has six SATA drive bays that natively support 3.5" hard drives, as well as 2.5" hard drives and SSDs, along with two M.2 NVMe slots for SSD caching. In a RAID 0 configuration, the T6-423 can transfer data at speeds up to 283 MB/s.

Also featured are two USB-A 3.2 Gen 2 Type-A ports, which allow it to be connected to external peripherals. Network connectivity is achieved via two 2.5 Gigabit Ethernet ports with port trunking failover support, which helps to provide redundancy in the case that a LAN connection malfunction occurs on one port. Supported RAID modes include RAID 0, 1, 5, 6, and 10, each of which provides performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD and Single modes are also available, allowing each drive bay to be individually utilized.

TerraMaster has engineered the T6-423 to be energy efficient. Not only does it feature two 80mm fans to help keep the system running cool, the server supports numerous scheduled power on / off cycles and hard-drive hibernation to further minimize power consumption and operational expenses. The T6-423 operates using an included external 120W power supply and also includes a power cord, an RJ45 cable, and screws. Protection is provided by a limited 2-year warranty.

The 6-bay T6-423 is suitable for SMB users who need high-performance storage solutions. High performance means that users can easily handle high-load assignments, while multiple business-level backup solutions guarantee user' data safety and prevent the potential risk of data loss.

This is a high-performance storage solution for iSCSI virtual storage and database service for SMB users. It features a 2.0 GHz Intel Celeron Quad-Core processor with a 2.9 GHz maximum turbo speed. It also features integrated graphics, AES NI hardware encryption, two 2.5GbE interfaces, and 4 GB of DDR4 dual-channel memory that is expandable up to 32GB.

The T6-423 can deal with high-load workflows and a high level of concurrent user access. Rapid document storage and management are facilitated by high-speed document retrieval, efficient transmission performance, and rich TerraMaster disaster backup and recovery solutions.

The T6-423 is configured with two 2.5GbE interfaces, supporting a 2.5GbE high-speed network bandwidth with a linear data transmission speed that can reach 283 MB/s in RAID 0. Link Aggregation offers a network bandwidth up to 5 Gb/s, thereby providing a cost-effective solution for multi-user and high-concurrent file access.

The T6-423 is configured with two 2.5GbE interfaces and Link Aggregation provides a network bandwidth up to 5 Gb/s. The built-in M.2 NVMe slots realizes SSD cache acceleration and significantly increases the storage efficiency of the disk array. To meet performance enhancement expansion requirements, the memory can be upgraded to a max of 32GB.

Structural optimization has remarkably reduced the space occupied by the T6-423, thus realizing product miniaturization. By adopting both vertical and horizontal designs, the T6-423 better satisfies the usage requirements of small-sized business users with limited space.

It is essential that a desktop NAS is very quiet. The T6-423 has a high-quality silent fan and optimized internal structure, which increases the equipment's internal wind pressure and reduces the working temperature of the hard disk. This remarkably reduces resonance between the equipment components and the hard disk, so even in a full-load working environment, the T6-423 maintains a low-noise performance.

The T6-423 supports rich RAID types, which can be selected based on your data access and data protection level requirements. Hot Spare can be configured for the disk array and any of the following array types can be chosen according to the number of hard disks: Single, RAID 0, 1, 5, 6, or 10. To reduce the risk of material loss and ensure important materials are kept, the T6-423 supports online capacity expansion and online migration of RAID array.

Supporting most file services (SMB, AFP, SFTP/FTP, iSCSI, NFS, and WebDAV), the T6-423 can fully satisfy file management requirements in different network environments. TerraMaster's web file management tool, File Manager, is easily operated with visualized interfaces, while its classification and search functions can make it simple to organize and share data.

Superior storage technology and optimized snapshot technology are the cornerstones of the BTRFS file system, which is what TerraMaster's T6-423 relies on for advanced data protection, the prevention of data corruption, and minimal maintenance expenses. This file system promotes high data integrity while promoting flexibility and efficiency in the areas of data protection and recovery. The Btrfs file system features data recovery capabilities at the file or folder level for faster data recovery and greater flexibility for businesses.

TerraMaster iSCSI supports VMware vSphere and Windows Hyper-V virtualization storage solutions. The simple management interface enhances working efficiency and optimizes calculation efficiency, as well as facilitating the shunt of storage operations.

Integrated with multiple backup applications, the T6-423 uses visual user interfaces and reliable storage technologies to protect your precious data.

Centralized Backup

Backups for virtual machines, employees' PCs, and file servers are managed centrally, facilitating the rapid restoration of data after an incident.

Duple Backup

To provide several offsite backup versions, Duple Backup offers advanced data protection by backing up files to another remote TNAS, file server, or cloud drive.

Snapshot

Take continuous snapshots of your folders or iSCSI LUNs by enabling snapshot schedule. When a disaster occurs, it can roll back to points-in-time and restore to the last backup, ensuring your data is well protected.

CloudSync

Back up your data to a mainstream cloud drive to provide remote backup versions, making your data more secure.

Business users can easily build file storage servers, mail servers, web servers, FTP servers, MySQL databases, CRM systems, Node.js, and Java virtual machines, as well as a host of other commercial applications.
