Does the DNS-321 Support 3.0 Gbps SATA or only 1.5 Gbps?
« on: February 11, 2009, 08:32:35 AM »

Does the DNS-321 Support 3.0 Gbps SATA or only 1.5 Gbps?  I have drives that require me to remove a jumper to go to 3.0 Gbps and if the device supports it, I'll go ahead and do that.  I don't anticipate a huge gain in speed, but possibly a little reduction in latency might be nice :-)  Just trying to make sure it is running at its best as I know it isn't a speed demon by any stretch.

I'm impatient...  I removed the jumpers to the Seagate 500GB drives I have to put them in 3.0 Gbps mode and the device came up just fine.

And was there any improvement in performance, any gain in speed, any reduction in latency?

RAID1 is for disk redundancy - NOT data backup - don't confuse the two.

I haven't measured it yet.  I was just making sure it recognized the drives and booted properly at first.  It seems snappy.  I'm on a 100mbit LAN, so I'm not sure if I'll see anything huge or not.

should work fine. The device supports SATAII 1.5 and 3.0 Gbps but your transfer rates bottleneck at the network.
