Dual-actuator hard drives become available

Mach 2 available for enterprises

Seagate's dual-actuator hard drive, the Mach.2, is now "available to select customers."

Mach 2 drives have two independently controlled sets of read/write heads and can sequentially transfer up to 524MBps double that of a fast "normal" rust disk and edging into SATA SSD territory.

The performance gains extend into random I/O territory, with 304 IOPS read / 384 IOPS write and only 4.16 ms average latency. Normal hard drives tend to be 100/150 IOPS and about the same average latency.

All this requires extra juice. Mach.2 drives are rated for 7.2 W idle, while Seagate's standard Ironwolf line is rated at 5 W idle. The Mach.2's power consumption is explicitly rated for several random I/O scenarios, while the Ironwolf line is rated for an unhelpful "average operating power".
