F5-421 - PRODUCTS
F5-421 : 5-Bay NAS for Small/medium Business
Powerful Configuration, Excellent Performance
With an Intel quad-core processor, the device’s main frequency reaches up to 1.5 GHz (max turbo to 2.3 GHz). It achieves read speeds of 119 MB/s and write speeds up to 118 MB/s, supports AES NI hardware encryption, and is ideal for small to medium commercial storage servers with 4GB DDR3 memory and four 1000Mbps network interfaces.
6-layer data security protection
The F5-421 device relies on the following six data security layers:
Automatic scheduled backup
Btrfs file system and snapshot
Multi RAID array security
AES hardware folder encryption and network transport encryption
Cloud drive data backup
File system Cluster
Enhance the Safety of your Data with a Next-Generation File System
Superior storage technology and optimised snapshot technology are the cornerstones of the Btrfs file system, which is what TerraMaster’s F5-421 5-bay NAS unit relies on for advanced data protection, prevention of data corruption, and minimal maintenance expenses. Use of this file system promotes high data integrity, all the while promoting flexibility and efficiency in the areas of data protection and data recovery.
Optimised snapshot technology generates 1024 snapshots for every shared folder, and up to 8,192 overall system snapshots. In this way, users can benefit from flexible, storage-saving data protection.
Since data recovery takes place at the file or folder level, businesses can also benefit from enhanced flexibility and efficient data recovery.
Faster and Safer
The device is equipped with four Gigabit network interfaces to support network aggregation and failover. If one network interface fails, the Internet connection can be maintained, helping to reduce the possibility of service interruption and the inconvenience of downtime operation. In addition, network aggregation can give full play to the advantages of the four network interfaces, which several times faster the connection speed and breaks the speed limit of a single network interface.
Large-Scale User Access
Support concurrent access for up to 1,000 users. You can also share storage space across multiple users, apply RBAC rights management and Windows ACL, and set access rights according to users, user groups, and folders.
Using SSD acceleration technology, transmission efficiency can be enhanced with a read-write optimised combination of hard disk and SSD cache. Effective SSD acceleration technology dramatically reduces I/O latency and improves storage efficiency by more than 20%.
Multiple RAID Modes
Support a variety of disk array modes, including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, JBOD, and SINGLE, to meet the needs of various users and levels of data security.
