Re: SSDs

But the delete still requires the "deleted" flag to be updated in the
DB and thus still requires a write to the drive.  And since data is
read/written in blocks instead of individual bytes, the whole block is
written....Perhaps SSDs have the intelligence to only actually write
the bytes that changed, I don't know.

Still, as I understand it, most enterprise SSD's have basically double
the flash memory required for their rated capacity; giving them plenty
of extra space to use for wear-leveling.
