Add Records To Table In Bulk (not One Record At A Time) Via Multidimensional Array

I'd like to add 600+ records at a time to a table (or at least a lot) and do this 1200 or so times. Yes, this is a very big table, its okay and the size is not an issue.

The key here is that speed is very important. I DO NOT want to AddNew and Update a recordset 700k times (one for each new record). I want to add 600 records or so 1200 or so times.

I am open to any way of doing this in VBA and/or SQL in MS Access; however, I am thinking of building an array that has 600 rows and 16 columns, then somehow add that to the table all at once. I will size the array down if it causes problems. That isn't the issue. The issue is how to add a 2d array to a table in bulk (all at once).

Code:
Sub test()
Dim dbLocal As DAO.Database
Set dbLocal = CurrentDb()
Dim sql As String
'build my array
Dim x(0 To 1, 0 To 1) As Integer
