@ 2018/04/19On Wednesday, Western Digital introduced its highest capacity hard drive based on conventional magnetic recording to date. The HGST Ultrastar DC HC530 can store 14 TB of data and uses perpendicular magnetic recording (PMR) with two-dimensional magnetic recording (TDMR) read heads to ensure consistent read performance. Because of extremely high areal density, the new HDDs offer up to 267 MB/s sustained transfer rate, slightly higher when compared to previous-gen drives. The new hard disks will be available in high volumes later this year.
The HGST Ultrastar DC HC530 hard drive is based on Western Digital’s latest helium-filled HelioSeal platform (5th generation) featuring eight 1.75 TB PMR platters and TDMR heads with two readers to ensure predictable read performance by mitigating effects of inter-track interference. The new platform not only packs eight 3.5-inch platters and features new heads, but also uses revamped (3rd generation) dual stage microactuators to improve head positioning and rotations vibration robustness, thus, advancing reliability of the datacenter-grade HDD in general. Other ingredients of the new HelioSeal platform include a top and bottom attached motor (with a 7200 RPM spindle speed), top and bottom attached disk clamps, RVFF sensors, humidity sensors, and so on. The new datacenter-grade Ultrastar DC HC530 HDDs are rated for a 550 TB/annual workload, a 2.5 million hours MTBF, and are covered by a five-year limited warranty.
The Ultrastar DC HC530 will be available only in 14 TB capacity with 4Kn and 512e sectors. The hard drive will feature a 7200 RPM spindle speed, a 512 MB buffer, and a SATA or SAS interface. The manufacturer will offer Ultrastar DC HC530 HDDs with hardware self-encryption capability, instant secure erase feature, TCG encryption, and TCG FIPS encryption to various parties. When it comes to performance, HGST declares up to 267 MB/s sustained transfer rate, a 4.16 ms average latency, a 7.5 ms seek time.
