I asked this question over in the DNS-323 forum because there was a topic over there specifically about 4k sector drives.  So if you saw this questions over there, it's a duplicate...

Anyway, I have just installed 2 Samsung HD204UI (2TB drives with 4k sectors) in my DNS-321 with RAID1.  I went ahead and used the web formatting to install the drives, and it didn't seem to have a problem.  However, I knew there were some issues with 4k sectors, so I did a little more research, and came across the post in the DNS-323 forum, so I thought I'd ask.  So far, I'm getting 133Mbps writes and 75Mbps reads, and I'm wondering if this will degrade due to the 4k sectors.  It's a new install, so I'm not worried about the data at this point.

This is what my drives look like as they are currently installed.  Can anyone interpret this and see if I should try to do a special, manual format to get the drives to work properly?  Or does this look good?  Does the start sector need to be 64 instead of 63?

Thanks for any pointers!

What problems were you seeing that caused you to look at the stats to begin with?  I have the same drives installed and have not seen any problems.
