Seagate Exos 2X14 HDD Delivers 524MB/s
At the company’s analyst event in February of this year, Seagate discussed their lineup of dual-actuator hard drives, a technology dubbed MACH.2. These drives have been shipping since 2019 and Seagate now has over a dozen customers using or trialing the technology. When combined with HAMR, these drives have the potential to both be very fast thanks to the twin actuators, but also very large. HAMR drives can grow much faster than PMR drives. Seagate has now shed some light on the capabilities of MACH.2 drives, releasing a data sheet for the Seagate Exos 2X14 that offers reads of 524MB/s.

Two sets of drive heads sounds a lot like double the chance for a physical failure to me. I'll be interested to get the Backblaze report on these in a year or so.

Is it right that any RAID would have to be done through a dual-ported SAS controller and OS?

The drive would present itself as a single logical unit, managing the two heads internally.

So it works like that with any SAS controller, like my old LSI? I might get one out of curiosity.
