The F4-423 4-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, AES-NI, and AES 256-bit encryption. It runs using TOS, a Linux-based operating system. This unit has four 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 F4-423 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 F4-423 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 F4-423 operates using an included external 90W power supply and also includes a power cord, an RJ45 cable, and screws. Protection is provided by a limited 2-year warranty.

Hot Spare can be configured for the disk array. It supports the creation of multiple storage spaces and, Ext 4 or BTRFS file systems can be selected in accordance with various business requirements. When used in conjunction with TerraMaster USB DAS devices, the F4-423 has the ability to flexibly expand storage capacity.

Professional Operating System

TNAS runs on TOS, a TerraMaster operating system developed based on Linux. Extensive research into the needs of various business users and the resultant continued evolution of multiple TOS generations has enabled it to integrate all-around professional storage management functions including network management, permission management, storage management, and resource monitoring via user-friendly, intuitive, and flat web interfaces. It also provides hundreds of free apps for the app market.

Across-Platform File Services

The ability of the F4-423 to support most file services (SMB, AFP, SFTP/FTP, iSCSI, NFS, and WebDAV) enables it to successfully address the cross-platform file service needs of different network environments. Moreover, the F4-423 supports Windows AD domain and LDAP, thereby facilitating the incorporation of the existing IT environments of business users and improving management efficiency. The presence of permission management at the level of users, user groups, and file directories means that the F4-423 can satisfy the comprehensive requirements of business users for inter-departmental collaboration and data security.

Rich Backup Solutions

TOS can protect valuable data using visual user interfaces and trustworthy storage solutions thanks to its integration with multiple backup applications that can address backup needs in an array of circumstances.

Centralized Backup

Backup for servers, virtual machines, employee PCs, and file servers can be initiated at the TNAS end, thus facilitating the rapid restoration of data after incidents.

Duple Backup

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

Snapshot

It is possible to take continuous snapshots of your folders or iSCSI LUNs by enabling the snapshot schedule with the advanced storage technology and optimized snapshot technology available via the BTRFS file system. When problems arise, the system can roll back to points-in-time and restore to the last backup, thereby ensuring that your data is well protected.

CloudSync

This backs up or synchronizes TNAS data with the cloud drive, which not only improves the availability of cloud data, but also provides several offsite backup versions, thus safeguarding the security of your data.

Virtualized Applications

The F4-423 satisfies virtualized application needs and provides additional functionality within one device with the use of professional virtualized apps, including VirtualBox and Docker, and by cooperating with Docker-compose and Portainer. This lowers the cost of corporate investment in IT.

System Level Security Protection

Increased cyberattacks mean that the security system of network devices must address considerable challenges. TOS enables various systematic safeguards, such as pam identity authentication, AES 256-bit encryption, automatic account lockout, anti-DoS attack, and firewall. Hence, it effectively reduces the risks of malicious attacks on your devices.
