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.
