By laying the foundation for a seamless data center, Western Digital provides the ability to conquer the data explosion with the Ultrastar DC HC500 series of hard disk drives (HDDs). The DC HC500 series is designed for private and public cloud environments where storage density and cost-effective infrastructure are critical. Ultrastar HC550 hard drives represent the commercial implementation of power assisted magnetic recording technology and use the triple stage actuator.Data center decisions are driven by TCO. The Ultrastar DC HC550, with 16 and 18 TB 1 , plays a key role in lowering TCO.Total Cost Of Ownership (TCO) Is The Driver Of Data Center ArchitectureData center decisions are driven by TCO. Higher capacity hard drives play a critical role in lowering TCO. An 18TB hard drive for a data center offers 29% more capacity than a 14TB hard drive in the same form factor. Compared to smaller capacity drives, higher capacity hard drives enable data centers to have lower capital expenditures by reducing system level and hardware support costs. High-reliability, low-power, helium-sealed disks reduce energy and maintenance costs, while promoting savings in operating expenses. For example, a data center using 18TB hard drives instead of 14TB can reduce the number of racks required by 22%,Raise The Bar On Capacity Thanks To New Technologies:- Ultrastar DC HC550 integrates a suite of technologies into a 9-drive platform to create hard drives like never before. The 18TB capacity is achieved by combining technologies that improve areal density and integrating with technologies that boost performance and reduce power consumption.- It is the first hard drive in the industry to master Energy Assisted Magnetic Recording (EAMR) technology, which improves writeability and thus increases areal density.- Features the industry´s first Triple Stage Actuator (TSA) which improves head placement accuracy and offers superior performance plus higher areal density.- HelioSeal ® technologyit is the basis for Western Digital´s high-capacity hard drives, spanning 6 generations of HelioSeal products. To date, Western Digital has shipped more than 65 million HelioSeal products.Features:- Magnetic recording technology- The triple stage actuator- HelioSeal Technology- Reliable design- HelioSeal design provides energy savingsSpecifications:General:- Type of device: Internal hard-drive- Ability: 18 TB- Form factor: 3.5´´- Interface: SAS 12Gb/s- Buffer size: 512 MB- Features: Rotational Vibration Protection (RVS), HelioSeal, Conventional Magnetic Recording (CMR), Sanitize Cryptographic Erase support, Media Cache Plus, Sanitize Cyptographic Scramble support, Two-Dimensional Magnetic Recording (TDMR), Energy-Assisted Magnetic Recording (EAMR) ,Triple State Actuator (TSA)- Width: 101.6 mm- Depth: 147 mm- Height: 26.1 mm- Weight: 690 Tradeinn.com Delivery: in United Kingdom Report	£357.99 Buy in shop
