Nothing unique about the -8E; any lsi2008-based HBA (with real/up-to-date LSI fw) is a valid testbed.

If your host is PCIe Gen3, just get a 2308-based HBA; that'll raise your ceiling to ~4.5GB/s.
edit: found some youtube benchmarks from artofserver, and a post on STH from Patrick himself...they seemed to max out around 2.2 GB/s
Either you misinterpreted, or their methodologies are flawed.

After all, your own test, while not ideal, still reached 2.8

Best to eliminate extraneous cruft.
Just do:
Code:
for i in DrvLtr1 DrvLtr2 ...
do
    hdparm -t /dev/sd$i &
done
and add up the speeds. Then multiply by 1.048 (hdparm does MiB).

I'm curious if you have added more drives since and what power consumption you are seeing. Right now I have a r720xd, r710xd, and a r530 all of which are fully populated.

Am using unraid and the r710 is running like 130w avg. So reading in another post that this 424x run around 250w idle it scared me a bit.

But it appears with the right psu's these idle pretty low actually.
Idle the empty chassis pulls ~32.2W with 2X Deltas and a IOM6 Controller.
Fully populated shelf of 24x 10TB SAS3 drives -Start Up, disk startup is staggered with 2x psus running - 100w-300W Peak when all were spun up
Settled Down and Idling, no HBA attached - 200W
Unraid Startup / Array start up - 200 - 235W
unraid Array Idle - 200-230W

I'm pleased to announce that with the 9207-8e I'm able to reach 3.7GB/s, which is the limitation of the current disks I have, and not the ds4246 or HBA!

Anybody want a 9200-8e? :)
