Okay.

So, one RAID card, eight SAS channels, and one 2 TB and one 1 TB drive
per channel (?).


Are you using any hardware RAID or JBOD capabilities under Wheezy?

External enclosure?  That card is for drives within in the same
enclosure as the card.


Where do the drives get power?

What is the make/ model of the drives?

Try disconnecting the RAID card and drives, and benchmarking just the SSD's.

Do you know if your amount of RAM is too much, too little, or just right?

Since you are not running encrypted drives, AES-NI won't help you there. 
  But, it should help with SSL.

Okay, so long as you understand each.

What does ZFS report for the size of the pool?

Okay.

When you ran Windows:

1.  Which version of Windows?

2.  Were the hardware and and CMOS settings identical to what they are
with Wheezy?

3.  Did you use the AOC-USASLP-L8i RAID hardware capabilities?  If so,
how did you configure it?

4.  Did you use any software RAID, Windows dynamic disks, etc.?  If so,
what software and how did you configure it?
