WD has launched a brand new line of Ultrastar onerous drives. The Ultrastar DC HC580 and WD Gold each supply 24TB, whereas the DC HC680 SMR encompasses a mammoth 28TB of storage. WD additionally guarantees improved velocity, because of its energy-assisted perpendicular magnetic recording know-how.
Relating to datacenter functions, high-capacity storage is king. In different phrases, HDDs aren’t essentially identified for his or her velocity. WD seeks to handle this concern. These merchandise leverage quite a few proprietary improvements – together with ePMR, OptiNAND, UltraSMR, and extra – to ship excessive density, environment friendly, and sooner drives to market.
How briskly precisely? Properly, very quick, not less than by HDD requirements. In response to the model, the WD Gold and DC HC580 promise a most information switch price of as much as 298MB/s. In the meantime its DC HC680 can handle a sustained information switch price of as much as 265MB/s. As a comparability, a normal HDD will learn and write at sometimes 80MB/s to 160MB/s. SATA111-rated SSDs learn and write between 200MB/s to 550MB/s.
Effiency can also be a significant factor. Relating to energy consumption, the drives have a ranking of 5.5W idle and 6.8W as much as 9.8W operational primarily based on 50/50 learn and write eventualities. Extra importantly, WD claims that resulting from its OptiNAND know-how, these three drives supply larger per-terabyte energy effectivity. To be actual, their terabyte-per-Watt energy effectivity is rated between 10% and 12% larger in comparison with earlier technology HDDs. Supreme for power-limited datacenters.
Lastly, at 24TB per unit, the Ultrastar DC HC580 and WD Gold every permit for as much as 612TB of uncooked storage per rack in a 102-bay 4U chassis. Moreover, WD’s Ultrastar DC HC and WD Gold have the additional benefit of a 550TB annual workload. A plus for reliability.
You may seize the WD Gold 24TB now with a $629.99 price ticket. In the meantime, the Ultrastar DC HC680 and HC580 HDDs are actually within the qualification section with choose CSPs, hyperscalers, and OEMs. Pricing for these will not be but out there. Discover out extra, right here. After all, there are numerous different WD HDD options out there for those who don’t fancy ready round.
