partitioning - what's the changed situation with partitions on ssd?

i've heard it said- why partition with ssds

i'm wondering why they would say that. Is the situation different from with spinning disk style hard drives.

The reasons with spinning disk drives, were

-smaller partitions are quicker to defragment

-could be quicker to format (though there is quickformat!)

-organization separating data and system onto separate partitions, and can wipe the system partition.

I know somebody may look at those reasons and still not partition a drive. But I am interested in what the reasons are, with partitioning an SSD drive, how the situation differs if at all?

Somebody suggested why not buy a few small SSDs. Though surely the same logic would apply to partitioning non-SSD drives? And surely with either, one is limited by the number of SATA ports.

And is the issue of partition alignment something that is relevant to both SSD and non-SSD? i've only heard of it recently, in SSD times.

Answer

The reason for using a partitioning scheme would be to allow for the presence of a Master Boot Record. Since one is only needed on the first hard drive, subsequent hard drives can have only a single volume taking up the full disk.

Partition alignment isn't a big deal in platter drives since they're so slow regardless that it really won't make that much difference.
