what are the benefits of HDDs over SSDs?
In: 2
one thing that hasn’t been mentioned is it’s easier to securely erase data from a hard disk as opposed to an SSD. on SSDs there are layers of abstraction that make it very hard for your operating system to know exactly where data “lives” on the drive, so when it goes to erase it, it may only be erasing references to the data, not the data itself. so if security is a concern (like real security, not just freeing up space), hard disks may be better because you can reliably overwrite the specific sections of the hard drive where the data lives.
