Expert Features ~ USED HDD 4TB Enterprise Capacity : Provides substantial storage for server data, backups, archives, business files, surveillance recordings, and high-capacity workstation use. 7200RPM Performance : Enterprise-grade 7200RPM spindle speed delivers quicker access and stronger sustained performance than slower archive-focused mechanical drives. SATA 6Gb/s Connectivity : Uses a standard SATA interface for compatible servers, workstations, NAS systems, storage enclosures, and desktop computers. Native 512-Byte Sectors : The 512n sector format supports legacy servers, operating systems, controllers, and applications requiring native 512-byte sectors. 128MB Data Buffer : The segmented 128MB cache helps maintain smoother read and write activity during demanding storage workloads. Up To 201MB/s Sustained Transfer : The underlying HGST Ultrastar platform is rated for typical sustained transfers of approximately 201MB/s under suitable conditions. Enterprise Ultrastar Platform : Manufactured by HGST for Hewlett Packard Enterprise and based on the Ultrastar 7K6000 enterprise-storage family. Native Command Queuing : NCQ intelligently organizes multiple storage commands to improve efficiency during simultaneous read and write activity. Rotational Vibration Safeguard : Enterprise vibration-control technology helps maintain head positioning and performance in systems containing multiple operating drives. SMART Monitoring : Self-Monitoring, Analysis and Reporting Technology allows compatible software to inspect drive-health indicators and recorded operating data. Secure-Erase Support : The HUS726040ALA614 variant supports overwrite-based Secure Erase with bulk-data encryption disabled. Power-Saving Modes : Advanced power-management modes include active idle, low-power idle, low-RPM idle, standby, and sleep states. 3.5-Inch LFF Design : Fits compatible 3.5-inch Large Form Factor drive bays and desktop-style SATA mounting locations. HPE Firmware Identity : Identified as HPE model MB4000GEFMK with HPE part number 820193-002 and HPE general part number 657753-008. Bare-Drive Configuration : The photographed product is a standalone hard drive without a visible HPE smart carrier, mounting tray, SATA cable, or power cable. Used-Product Value : Delivers enterprise-level capacity at a lower cost than a new enterprise HDD—maximum terabytes, minimum wallet drama. Compatibility Check Required : The host system must support SATA drives, 4TB capacity, native 512-byte sectors, and a 3.5-inch mounting location. Individual Health Varies : Because this is a used product, SMART status, power-on hours, bad sectors, noise, remaining lifespan, and actual transfer performance must be verified for each unit.
