Product Description
TerraMaster F5-221 5-Bay NAS
for Small Business and Personal Cloud Storage
Powerful Configuration, Excellent Performance
TerraMaster’s F5-221 5-bay NAS unit comes with an Intel dual-core processor, a frequency of up to 2.0 GHz, a read speed reaching 119 MB/s, and a write speed reaching up to 118 MB/s. These devices are compatible with both AES hardware encryption and 4K HD video transcoding, making the F5-221 an ideal candidate for home multimedia entertainment and small office applications.
Multiple Layers of Data Security
The F5-221 device relies on the following five data security layers:
Automatic scheduled backup
Btrfs file system and snapshot
RAID 1,5,6 array security
AES hardware folder encryption and network transport encryption
Cloud drive data backup
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 F5-221 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 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.
4K Ultra HD Video Transcoding
Compatible with the DLNA protocol, third-party’s multimedia servers enable users to stream 4K media content from TNAS to multimedia playback devices. The device offers 4K H.264 live transcoding（Max size: 4K H.264/H.265 8-bit 30fps）, along with the opportunity to convert and playback 4K video on computers, smartphones, and media players that lack native support for HD formats.
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
TNAS.online spares you from setting up DDNS, complicated network settings, 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 with other work files, on your Internet-enabled device.
Striving to Satisfy Small Businesses
Small businesses benefit from the opportunity to conveniently 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.
