02/02/2023 at 18:41 from Maurice Riebling – Western Digital is also offering a dual-actor HDD with the Ultrastar DC HS760 after Seagate. Compared to the competition, it offers more storage space and apparently also slightly better performance.
Western Digital will also be offering an HDD with a dual actuator for sale in the future. The Ultrastar DC HS760 is in direct competition with Seagate, which has been offering hard drives with this technology for a long time.
So there was Seagate’s first dual-actor HDD 2021 with the Exos 2X14 to buy, while the successor model with the Exos 2X18 was presented in November last year. Western Digital can surpass the 18 TB offered there with the Ultrastar DC HS760 by 2 TB – there is a total of 20 TB – and also points to somewhat faster transfer rates, although no specific figures are given on this point. They can only be written between the lines read out.
Direct Storage in the video test: no more loading times?
The product description advertises a sequential data throughput that is up to twice as high. As a comparison product 20TB Ultrastar DC HC560 HDD, as can be seen from the footnotes on the product page. It offers up to 291 MB/s here, which, conversely, indicates sequential transfer rates of up to 582 MB/s for the Ultrastar DC HS760. With random access, the performance improves by a factor of 1.7 (RW 50/50), while the energy efficiency, measured in IOPS per watt, is 37 percent better here in the scenario of 70 percent reads and 30 percent writes.
A total of 9 platters are housed in the housing, which rotate at 7,200 revolutions per minute. Western Digital uses helium for filling. Ultimately, the use of the 3.5-inch hard drive in the context of data centers is being considered. Accordingly, there is also no exact price information, while the only interface to choose from is SAS. Seagate’s Exos 2X18 is also available with SATA in comparison.
