Not exactly what you asked for, but -- I think very highly of
the HP P800 SAS/SATA card. You can get a 1U box with four 3.5"
drives -- don't buy HP drives, the price is astoundingly high --
and later plug in a 2U 12x3.5" chassis or a 2U 25x2.5" chassis.
These can be cascaded, too -- 96 3.5" disks (up to 2TB SATA) or 
50 2.5" disks (500GB SATA or 300GB SAS) depending on whether you
need more speed or space.

Alternatively, any decent 4 disk 1U box can do 4TB (usable) in
RAID10 for you. 

IMHO, small NAS appliances are primarily for people who can't be
bothered to set up things that you've already set up.
