original title: Western Digital released new enterprise 10TB mechanical hard disk products of ultrastar DC hc330 series

western data has just released products for storage servers, raid arrays And distributed storage ultra star DC hc330 series high-end enterprise inflatable mechanical hard disk, with a maximum capacity of 10TB per disk. In terms of performance, it introduces the company's media cache plus cache technology, which is expected to improve the write performance by up to 40% in some cases. There are also 4tb, 6tb and 8tb versions of this series of HDDs. Although it is classified as the "DC" product line, it is not the main data center, but those enterprises that pursue high-capacity storage space and high performance

all hard disk drives in the lineup are built based on the company's enterprise platform, using a durable and reliable traditional vertical magnetic recording (CMR) scheme, supplemented by bottom and top connected motors, Raff anti vibration, dual micro actuators, improved positioning, etc

ultrastar DC hc330 10TB version has six 1.66 TB CMR disks built in, which is the commercial disk with the highest storage density at present. For comparison, the helium filled ultrastar HE10 series is composed of seven 1.42 TB PMR discs

the speed of the hard disk is 7200 rpm, the cache capacity is 256MB, and the SATA 6 Gbps or SAS 12 Gbps interface is optional, as well as 4 KB and 512e sectors

with the addition of high-capacity disks, the ultra tar DC hc330 10 TB version can increase the continuous transmission rate to 273 mb/which means that it can only be sold to a limited market at a lower price, which is no less than some cheap solid state drives (SSDs)

in addition, the new hard disk introduces media cache plus technology, which can improve random write performance by 40% when the queue depth is low or the transmission length is short

theoretically, compared with ultra star HE10, reducing the number of disks should reduce the power consumption of the sensor ltrastar DC h330 caused by U. The power consumption of the new hard disk in working mode is 9.2w, higher than the previous 6.8w, but this does not mean that it is worse than the 10TB version of the former

first of all, one less disc can reduce the manufacturing cost. Secondly, it can be faster in some dense write scenarios. Therefore, it is still efficient enough for most use cases that meet the product positioning. On the other hand, even in the idle state, its power consumption is increased by 3W (8W vs 3W) compared with the previous generation products

Western Digital said that it would provide ultra star DC H2 to OEM manufacturers, cloud users and manufacturers in September this year High temperature resistant tungsten steel needle: 2 sets( φ 2mm~ φ 8mm) C330 10 TB hard disk, the specific price depends on the quantity purchased in each batch
