Product Features
Technical Overview
At the core of the TS-433EU is an ARM Cortex A55 quad-core processor running at 2 GHz, delivering efficient performance for storage operations while maintaining low power consumption. The system includes 4 GB of standard memory and 4 GB of flash memory for the operating system, ensuring responsive performance even under moderate loads.
Storage management is handled through Serial ATA/600 controllers supporting eight RAID levels including 0, 1, 5, 6, 10, 50, 60, and JBOD configurations. This flexibility allows administrators to optimize for performance, redundancy, or capacity based on specific business requirements. The system supports up to four 3.5" drives or 2.5" drives through the included mounting hardware.
