Well technically yes, but I could counter argue that we have 'living memories' that we can not only replay at any time (any of them, without any buffering or delay), but also change and combine with other memories to create new memories. Additionally if someone tells you something the brain can search all your memories in what seems to be a microsecond and pull up the relevant ones (file search on steroids, that can even search every single frame in all your recorded movies). Much more useful than static data on a hard drive.
