TERRAMASTER U12-500 Plus - NAS file server, Grey

The TERRAMASTER U12-500 Plus 12-Bay NAS File Server, Intel Core i7-1255U, 16 GB DDR5 is a 2U rackmount network-attached storage device designed for centralised file storage, sharing, backup, and data management in small to medium-sized business environments. It ships without any drives installed, providing twelve hot-swappable bays that accept 2.5-inch or 3.5-inch SATA HDDs and SSDs, supporting a maximum raw capacity of 288 TB depending on the drives and RAID configuration chosen. An Intel Core i7-1255U processor with 10 cores and 12 threads, boosting to 4.7 GHz, handles computation alongside 16 GB of DDR5 SO-DIMM memory in a two-slot configuration expandable up to 64 GB. Two 10GbE RJ45 ports handle network traffic, and two M.2 slots are available for SSD caching. The system supports RAID 0, 1, 6, 10, and JBOD, with online RAID expansion and migration for adjusting array configurations without downtime.

Build characteristics include a grey metal 2U chassis measuring 440 by 88 by 550 mm and weighing 16 kg, with a built-in 550 W power supply drawing approximately 120 W under typical load. Cooling is handled by three active 80 mm fans, producing a stated noise level of 39 dB. The NAS runs TERRAMASTER TOS and offers web-based management accessible through Google Chrome, Mozilla Firefox, Apple Safari, or Microsoft Edge. Network protocol support covers CIFS/SMB, NFS, FTP, TFTP, HTTPS, SSH, iSCSI, SNMP, and SMTP, with link aggregation and jumbo frames available for throughput optimisation. The system accommodates up to 2,048 user accounts and 512 shared folders, with ACL-based access control for granular permissions. Supported file systems include Btrfs, FAT32, HFS+, NTFS, EXT3, and EXT4, and the device is compatible with Windows, macOS, and Linux client environments. Backup capabilities span cloud backup, USB-drive backup, centralised backup, synchronisation, and snapshots. Two USB 3.2 Gen 1 Type-A ports and one HDMI port are present for peripheral connectivity and display output. Security features include AES encryption, password authentication, SMART drive monitoring, and bad-block scanning.
