External NAS to samba

[Merrill Oveson]

Plug:

Looking for suggestions for the following....

I need to extend the disk space of my samba server.

So I'm thinking external hard disks via eSATA.

Here's what I'd like:

External Box:
1) capacity to add drives
2) built in hardware Raid 5
3) hot swappable disks
4) eSATA connection

anybody know of anything of there like this?

I'd could even live without options 1 and 3.

Please don't suggest NetApp or EMC - way way too expensive.

I just need a system that "shows" one hard disk that's raid 5 that
allows for eSata - nothing fancy like NetApp.

Thanks

Merrill
