I'll let everyone know how they work with my setup when it arrives (Adaptec 5805 and Chenbro CK13601 expanders)

Turned down my offer of 150 with free shipping. He want 160 to ship to Canada or 35 to ship an hour away from me at the border. Still deciding.
Mine was delivered today from digitalmind2000 FedEx Ground (only took 1 day!) and they left it at my front door. I can't test it yet, but I'm impressed with the build quality. There is zero dust in mine or any sign of wear besides a couple scratches in the top when it was slide out of the rack.
Wish I had some cash right now. I'd order a couple of em. Waiting for packetboy to get his and see what compatibility is with LSI cards.
They shipped yesterday...should arrive on Feb 10th. I've got enough spindles to populate 3 of these enclosures so should be able to put this through it's paces.
What I am really curious about is if the expander included with these supports SAS Multiplexing....that's what enables you to put 3Gbps drives in the enclosure but still make full use of the 6Gbps linkup from the enclosure to the HBA.
In other words 16 3Gbps SATA drives would be about 1600MB/s. If enclosure upload is limited to 3Gbps * 4 (SAS wide port) upload would be limited to about 1200MB/s...thus you wouldn't be able to achieve the full potential of the enclosure.
OTOH, if the enclosure will function at 6Gbps, then you've got 2400MB/s to play with and thus no bottleneck.
We'll see.
Anyone who tests these on an ARC-1882/1880 can check this.
Go to Information -> SAS Chip Information in the web interface and it will list under attached expander the number of lanes and what speed. I had two SFF-8087 cables hooked up to this expander and it was 6 gig SAS drives so it lists 8x6 G for 8 lanes (4 per cable) of 6 gigabit:

Thanks, I was curious what expander chip was in this thing and it looks like a LSI SAS2X38
Ah sorry for the confusion this is not the cheap JBOD thing I was just showing examples of areca controllers showing the sas chip info =P
That screenshot is from an ARC-1882 hooked up to a supermicro chasis with built-in 6GB SAS expander (24 slot 4u chasis) not the chasis in this thread.

Any updates?
Generally if people are happy with theirs and the speed is adequate. I know one poster from Canada was not.
I'm still waiting on some more hardware so I can test it in another system but I doubt the enclosure is causing the low speeds, I'm thinking the motherboard is being wonky with the PCI-e speeds or there's something funky going on with my Adaptec. If anyone else could post some HD Tune results that would be awesome though. Since I'm limited by gigabit ethernet I'm not overly concerned about the speeds but I'll definitely make sure to post my results on my other motherboard.Check out post #40
Also, I just want to make sure if i try to source them locally (hardware store or such) that these are 6-32 x 1/4" countersunk head machine screws... i think.
Check out post #40
Got my stuff a few days ago and installed them last night with 2 Seagate drives. As soon as I get the screws to install more drives, I will put them through some testings. Here is what it shows for my ARC-1880x for those interested (so it's doesn't have SAS mux):
Host Interfaces Two external 6Gb/s SAS 2x wide ports via two SFF-8088 mini-SAS interfaces (front cabled)
I would tend to think it is possible that the expander boards are different between units, though most of the ones purchased from the same supplier (likely same batch installed then decommissioned at the same time) should have the same board installed. I will collect what information i can from the one i received when i get everything connected and have time to poke around.
I think this maybe true. It may very well be that OMNISTOR SE3016 is different than SGI InfiniteStorage 1116 because the ones we got from digitalmind2000 have firmware version 0102 while OP has a different firmware version (0227).
Hey, You mean he wanted $160 total, including shipping, to ship to Canada? or $160 on top of the $150?
