TerraMaster F4-421 4-Bay Professional NAS
Overview
Powerful Configuration, Excellent Performance
With an Intel quad-core 1.5 GHz (turbo boost up to 2.3 GHz) processor, 4GB
DDR3 memory, two 1Gb Ethernet ports, and AES NI hardware encryption,
TerraMasters F4-421 is ideal for small and medium-sized commercial storage
servers.
Multiple Layers of Data Security
The F4-421 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 TerraMasters F4-421 4-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 512
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 two 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 two 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 500 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.
SSD Cache
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.
A Private Space in the Cloud
TNAS offers users the opportunity to establish a personal cloud drive that
satisfies their remote access needs. Rights of access can be tailored for your
colleagues, relatives, or friends, and with support for two-way sync cloud
drive, enjoying the benefits of convenient cloud life has never been
easier.
TNAS.online for Simple Remote Access

and further port forwarding rules when trying to access files on TNAS through
the Internet. At no additional expense, the service provides a secure,
modifiable URL that you can use to engage with audio and video content, along
