Please advice me a RAID-5 controller

[thor]

Hello!

I need a hardware PCIe SATA/SAS RAID controller. Requirements:

1) RAID-5

2) Supported in FreeBSD AMD 64

3) Supporting more than 2TB per drive

4) Old enough to be bought cheaply on EBay.

5) Speed is not critical; problem is the maximal volume per installation.

6) Tape support is welcome.

Previously I tried P-800 and Dell PERC 6/i. Unfortunately P-800 control 
utility is proprietary and both have a hardware limit of 2TB per drive 
so only 12TB+parity per controller.

Could you advice me something similar to PERC 6/i but more than 2TB per 
drive?

Thanks.
