MSDE -v- JET4 and SQL2000

Is it correct that MSDE is much faster than JET4 ?
I've got an application we have written using JET4.
We are producing a SQL2000 version and want to decide if to convert the JET4 into MSDE and abandon JET4 all together.

Where do I get MSDE from ? I can't find anything about it on Microsoft product pages. Does it come bundled with something else ?

MSDE is the free limited version of SQL server which comes with Office Professional and Visual Basic/Studio Professional.

You can download it on the Microsoft website (

Jet 4.0 is the ADO driver for using Access 2000 and up files and has nothing to do with SQL server or any other database server.

As Arnout pointed out, when you use Jet, there is no actual
database server. This makes multiuser concurency problems
much harder to deal with. MSDE is ideal for a small setup because
it exactly duplicates SQL Server, so upgrading to SQL Server is
totally painless. You can even disconnect a database from MSDE,
and reconnect it to SQL Server, and use Enterprise Manager in
SQL Server to maintenance a linked MSDE server.

About the only differences between MSDE and SQL Server 2K is that MSDE is limited in the number of concurrent users, and the database size is limited to 2 GByte. Also, MSDE doesn't come with any any front-end administration tools. If you are interested, I posted a simple Admin Tool ( for MDSE in the Code Library a while back.

The downloadable version of MSDE doesn't come with the Enterprise tools. However, the version you can order from MS (not free, but quite cheap, about 8 USD) does come with them.
