It's HAMR time.

It's HAMR time.

I see what you did there...

And to think that some people were saying that the HDD is dead. I knew very well that it wasn't because sure, SSDs far WAY faster but they don't have the same capacity as the HDD while still being somewhat affordable. Also, if you accidentally delete something from an SSD, there's no getting it back. With an HDD, you can use a program like recuva to bring it back (if you move quickly enough).

Magnetic drives will always be useful for things that don't require insane speeds like documents, audio, video, mass data storage and system backups. Hell, you can get 8TB EXTERNAL drives from Costco for under $200. They're not high-speed drives but these days, even a 7200RPM drive gets toasted by a cheap SSD so there's not much point in getting them anymore. The biggest benefit from magnetic storage is no longer speed, it's capacity so forget about the speed and just get the capacity.

We need to demand Multi-Actuator technology from ALL the HDD companies.

Imagine 2x, 3x, 4x, actuators running in parallel, reading data at super high speeds like a mini internalized RAID per drive.

You'd actually multiply the Sequential R/W throughput and improve Random IO over night for very little cost.

Seagate even stated that Dual/Multi-Actuator had only 1 platter penalty to implement, but it doubled the speed.

That's a big deal when Single Actuator HDD's have barely touched the 300 MBps Throughput of SATA 2.0 at peak burst speeds.

I can envision a day when we have 11 Platters and 2x-4x actuators hitting 600-1200 MBps. That's going to be glorious for Sequential R/W throughput.

How reliable these Are in the long run compared to conventiona harddrives?

The chances are high they may develop bad sectors much sooner than later. Twice the actuators, 2 times the chances by head accidentaly touching the disk surface?
