Global Drive Shortages – We are constantly receiving drives and allocation is strictly
based on orders received and captured payments only. Our priority will be NAS integration orders. Drive only orders will not be accepted if we have no allocation. We will not accept and calls or emails for any drive only queries, as we are prioritized for NAS based orders only. Thank you for your understanding.
WD/HGST Ultrastar DC HC310 HUS726T4TALE6L4 (0B36040) Enterprise hard drive, 4TB, SATA 6Gb/s, 7200RPM, 256MB Cache. MTBF (hours) 2,000,000, annualized failure rate 0.44, load/unload cycles 600,000, error rate <1 in 10, 5 year limited warranty.
The Ultrastar family delivers a long-standing tradition of reliability leadership with MTBF ratings of at least 2M hours and a 5-year limited warranty. Ultrastar capacity, power efficiency and reliability provide customers with a lower total cost of ownership.
Ultrastar hard drives feature up to 10 times the workload rating of desktop drives and employ advanced technologies for enterprise-class reliability, power efficiency and performance. Designed from the ground up to be an ultra-robust storage device, Ultrastar drives are the perfect solution for your business.
High Workload Rating
Delivering dependable performance to any storage environment, Ultrastar hard drives are designed with a workload rating up to 550TB per year*, among the highest of any 3.5-inch hard drive.
Enterprise-class Storage to Rely On
Ultrastar is our top-end drive for data centers. With up to 2.5 million hours MTBF, Ultrastar hard drives deliver reliability and durability, are built for yearly operation (24x7x365) within the most demanding storage environments, and are backed with a 5-year limited warranty.
Featured in over 30 million Western Digital hard drives shipped**, HelioSeal technology allows for higher capacities and lower power on large storage arrays. And now on its 5th generation design, HelioSeal technology is field-tested and proven to deliver high capacity, reliability, and power efficiency you can trust. HelioSeal is a key technology on 10TB capacities and above.
Enhanced Rotational Vibration Safeguard (RVS) technology uses sophisticated electronics to monitor the drive and correct linear and rotational vibrations in real time for improved performance versus traditional desktop drives in high-vibration environments.
Dynamic Fly-height Technology
Each read-write head's fly height is adjusted in real time to ensure consistent performance for reduced errors and optimized reliability.
Dual-stage Actuator Technology
Ultrastar drives feature a dual-stage actuator head positioning system for a high degree of accuracy. The primary stage provides course displacement while the secondary stage uses piezoelectric motion to fine tune the head positioning to a higher degree of precision.
All Ultrastar hard drives are extensively tested across a variety of popular OEM storage systems, SATA controllers, and host bus adapters to ensure ease of integration for a plug and play solution.
This family of 7200RPM-class hard drives delivers the fastest performance with the highest workload rating of any drive in Western Digital's hard drive lineup. Ensure you have the most capable hard drive regardless of the application with Ultrastar hard drives.

The selected drives are batch controlled and tested using our HDD and SSD servers. Passed drives are then installed in the NAS with Volume and RAID set. Our pre-burn testing prepares the NAS with an initial system and drive testing cycle to ensure that the integrity of the entire system is tested and passed with no issues at all.
Our stress testing (burn-test) cycle commences for a minimum of 24 hours and extends to 48 hours if requested or required. This is undertaken in order to ensure stability when used in a normal environment. These tests can include extremes of workload (constant I/O's), CPU and memory use, thermal load (heat), clock speed, or voltages, bus and connectivity components, with the primary stress testing software aiming to test stability by trying to force a system to fail. Our tests put a greater emphasis on robustness, availability and error handling heavy loads.
Once the tests are complete we QA and pack the system back into it's retail box. Then it's double boxed to protect the unit during shipping. You receive your QNAP NAS Ready To Plug 'N' Store. It doesn't get any easier. Buy your NAS from the QNAP EXPERTS at QNAP DIRECT.
