There is a maximum number of main partitions that may be established on a hard disc because of this limitatio

On succeeding drives, attempts are made to store concurrent sections of a file. Is there a justification for why this is so important for magnetic disks? If SSDs are accessible, is it still essential to use them, or is it a waste of time? What causes this?

It is common practice for operating systems to attempt to store files sequentially on the same block of storage media. Why is this so critical in the case of magnetic disks?

Operating systems make an effort to save individual pieces of a file in a sequential fashion on disk. So what if we use magnetic disks for it?SSDs: necessary even if you don't use them? Is this anything that we can figure out?
