The Taiwanese company Qnap does that NAS system TS-431 KX also on the German market. It is a system in the lower price segment. Qnap had already announced all products in the series at CES 2020 earlier this year. The feature is 10 Gigabit Ethernet, which is possible via SFP + fiber optic connection. Alternatively, a network connection can be implemented via two RJ-45 sockets on the back.
The TS-431 KX has four 3.5-inch drive bays for various SATA-3 hard drives. However, it is also compatible with 2.5-inch SSDs and HDDs. The bays have easily accessible brackets with which drives can be hot-swapped during operation. The Annarpurnalabs Alpine AL-214 is also installed in the housing. This CPU has four cores at a clock speed of 1.7 GHz, but uses older 32-bit architecture.
2 GB of DDR3L RAM are preinstalled on the single-channel SODIMM slot. A maximum of 8 GB RAM is supported. The operating system QTS 4.4.2 is preinstalled on the 512 Mbyte flash memory, which is in principle an embedded Linux. The NAS has three USB 3.2 Gen1 ports installed, but USB-C is missing.
RAID and AES encryption
The product supports various file systems for externally connected drives: Ext3, Ext4, NTFS, FAT32, HFS + and – with the appropriate license driver – Exfat. However, the internal drives are formatted in Ext4. RAID configurations 0, 1, 5, 6, 10 or just JBOD are supported. Data can be encrypted with the NAS using 256-bit AES. Two-factor authentication can also be set up for the system.
