Seagate has been engaged on dual-actuator arduous drives—drives with two arms and browse/write heads per platter—for a number of years. Its first manufacturing dual-actuator drive, the Mach.2, is now “obtainable to pick prospects,” which means that enterprises can purchase it straight from Seagate, however end-users are out of luck for now.
Seagate lists the sustained, sequential switch charge of the Mach.2 as as much as 524MBps—simply double that of a quick “regular” rust disk and edging into SATA SSD territory. The efficiency positive factors lengthen into random I/O territory as nicely, with 304 IOPS learn / 384 IOPS write and solely 4.16 ms common latency. (Regular arduous drives are typically 100/150 IOPS and about the identical common latency.)
The added efficiency requires further energy; Mach.2 drives are rated for 7.2 W idle, whereas Seagate’s normal Ironwolf line is rated at 5 W idle. It will get harder to check loaded energy consumption as a result of Seagate specs the Mach.2 in a different way than the Ironwolf. The Mach.2’s energy consumption is explicitly rated for a number of random I/O eventualities, whereas the Ironwolf line is rated for an unhelpful “common working energy,” which is not outlined within the data sheet.
Nonetheless, if we assume—in all probability not unreasonably—an identical enlargement of energy consumption whereas beneath load, the Mach.2 represents a superb selection for energy effectivity because it provides roughly 200% of the efficiency of competing conventional drives at roughly 144% of the ability funds. Notably power-conscious customers also can use Seagate’s PowerBalance mode—though that characteristic decreases sequential efficiency by 50% and random efficiency by 10%.
In keeping with Seagate Senior VP of Enterprise and Advertising Jeff Fochtman, the corporate has been delivery Mach.2 HDDs in quantity since 2019, supplying them to over a dozen main enterprise prospects with dual-actuator packages. At present’s wider launch expands the potential buyer base to incorporate the remainder of Seagate’s “choose” prospects.
