Integrated RV Sensors
Regular hard disk drives without RV sensors can affect the performance of a multi-bay NAS system by generating 'knock-on' vibration. This Toshiba HDWG440UZSVA drive ensures high reliability by minimising vibration effects through its advanced control and sensing technology. Multiple sensors detect the slightest shock and built-in RV sensors also compensate for rotational vibration, eliminating the possibility of 'knock-on' vibration in multi-bay NAS configuration systems.
Reliable Always-On Operation
NAS systems in small businesses or creative environments often need to be accessed by several users, at different locations, simultaneously. Therefore, today's NAS drives must deliver high data transfer rates and simultaneous upload and download 24 hours a day, 7 days a week. Offering high reliability and scalability, this HDWG440UZSVA drive achieves a maximum workload factor of 180 TB/year, up to three times more than conventional desktop hard drives.
High Durability and Heat Prevention
Use of high-endurance components is one of the reasons that the HDWG440UZSVA drive offers better durability than other conventional hard disk drives. At the same time, automatic adjustment of seek speed to reduce heat during high-temperature operation further improves endurance in demanding situations.
High Speed for Multi-Drive Environments
High performance and fast read speed is made possible under high data access loads from multiple users thanks to 256 MB data buffer. This makes this 4TB drive suitable for small businesses and creative professionals looking for solutions to handle high data volumes using multi-RAID NAS environments.
Optimised Cache Allocation
Toshiba’s Dynamic Cache Technology, a self-contained cache algorithm with on-board buffer management, optimises how the cache is allocated during read/write to provide the high-level performance demanded by real-time domains.
