Yes, the global write lock essentially means that you can't parallelize your write, though I hear that collection level locking is on the horizon. Unverified writes are generally bad for transaction data.

If you _really_ think you need 1,000 writes, only a complete in-memory DB like Redis can offer that... My suggestion would be to go with a simple set-up and consider scaling issues when the need arises - they are always a good headache to have.

Good info, thanks.

MySQL it is then. :)

Just keep in mind that MySQL doesn't scale easily. Master/Slave relationships get tricky to manage. I've only had minor experience with this, but it was enough to know to avoid it.
