I just got one yesterday. It should arrive by Monday. I had a bunch of 
special instructions for shipping and the cat from Interialcomputing was 
cool about it, and responded right away. 

I'll test it against the ACARD unit using my fastest Indy (R5k/180). I 
also own an Adaptec AHA-2940. It's a fast-scsi2 PCI adapter and is 
probably one of the most well supported SCSI adapters I've known. It has a 
50-pin internal adapter I can connect to the SCSI2SD unit. This way, I can 
benchmark using BSD & Linux, too with all kinds of fancy modes, 
schedulers, filesystems, and benchmarking tools. I'm partial to 'fio' and 
'iozone' for benchmarking, but I often also use 'dbench' to hammer 
concurrency tests. Of course, it won't be very fair from the standpoint 
that I'll be using a SanDisk UHS class-10/u3 card in the SCSI2SD versus a 
Samsung 850 Pro SATA SSD in the ACARD ARS-2000SUP. It should be an easy 
sweep for the ACARD, but we'll see.

I'll blog it up and post it once I'm done.
