Now that I'm reading things right, I'm guessing md1 and md0 are both fully utilizing the ESATA connection with 4 drives connected to each channel.
but md0 is nearly 7 times faster. Just because RAID10 vs RAID1? I would understand if the RAID10 is twice as fast, but 7 times is a bit much.
Well, that is 6 drives compared to only 2... still, 7 times as fast is odd.
You said you had 5400RPM drives? That would account for the slowness.

The 6 disk RAID 10 should be 3 times faster, but I'm not sure about this. Don't know how up to date this http://wintelguy.com/raidperf2.pl is

The expanders are 4 drives each, and the RAID 10 is 6 drives of one of the two channels and the RAID1 is two drives on one.

Ah ok

So this looks like an MD array, is this running on XenServer?
-
Also you've got approx 8TB of space there, correct?

Yes.

It is. Hopefully I won't have any oddness formatting these as ext3 when that completes.

Any reason for not using ext4?

I was going to ask the same question that @thwr asked, along with what is the hardware set?

WD RED and Seagate NAS drives for the RAID 10, whatever 1TB drives happened to be lying around for the two RAID1 sets. (I prefer HGST drives when buying drives today.)
ext3, because XenServer
Apparently, XenServer is one of those "we don't get storage" vendors.
