Seagate ST4000DX000-1C5160 [3726 GB] 4TB
firmware cc42 date 12047 dom 7/2011
bare drive pulled from usb3 external @ http://www.amazon.com/Seagate-FreeAgent ... 914&sr=8-1
single drive, boot menu factory defaulted, all frontview defaults.

drag/drop 15g from ssd via cifs gbit to default backup share
peaks of ~115mibs
windows dialog reported speed ~79 mibs
reading same 15g file back to ssd showed 110 on windows copy dialog, constant 115-118 on netmeter
other notes;
only 1 drive at this time, so unable to test raid/expansion
drive seems to be pretty quiet, can't really hear it over the device fans
spent about 30 minutes on each device, so no extended testing, just setup and a few drag/drop transfers
Can't wait for tax return time or saving up for 5 more drives, I'm looking forward to 6x 4tb in dual redundancy.

- well I bit the bullet and did the offline expansion documented here, and while the expansion seemed to go ok with no errors, the fsck after the expansion had a bunch of errors that I let it fix which was worrisome, but from what I can tell all data is ok.
While trying to install lsof, I screwed up my sickbeard install so now that seems to be the only thing not working right.sauron:/c# df -h

I had thought I had last defaulted with all 6 drives, but now maybe I am not so sure.
I am using dual redundancy, so if I am hitting a limit, it would be the 8tb expansion limit, volume size should be nearly 15tb instead of 12.
It would have been really great if the error message actually explained more details about what the problem is, instead of just saying expansion failed. But I suppose we won't be seeing any improvement there now. - There are two expansion limits. One of them is that you can't expand your volume by more than 8TB over the life of the volume. What was the capacity of the volume when you last did a factory reset?
If your volume is using single-redundancy then you would be running into the limit that you can't expand past 16TB - 5th disk replacement and expansion went fine, however after the 6th...
Incompleted file system expansion detected. Resuming... Volume expansion failed
Even after a reboot cycle. Ugh. - could be, my plan is to initially add them to my probus, but eventually I want to swap them out to drives matching the existing 4tb hitatchi's, and move the seagates over to my ultra4.
- I added one of these recently for dual redundancy. I think it's an odd 5900Mhz drive. It is slower than the original ones that came in these seagate enclosures, but even with 1GB/s networking the network is the bottleneck so I like the slower cooler drives anyhow.
- I assume this is a newer revision of the drive in the original post, I will be finding out in a couple days. Buying 2 of them to max out my probusiness with 6x 4tb.

It's 4TB not 4GB. Similarly 3TB not 3GB.
Yeah I could split it up I guess until my movies folder exceeds 4TB which its getting close. If I loose the volume i will replace the disk, re-create the volume, and copy all the data back on next backup run.
Yeah typo have been fixed from GB to TB :)- Two or three 6-bay ReadyNAS units is a much better option than a 3200/4200 for the home. Cheaper and probably less power usage too. Certainly less noisy.
It would be nice to see an 8 or 10 bay unit. I'd be interested in getting one of those. - Yes it does. But this is not a critical data. If you lose the entire array you simply re-download a few gigs of data (for the TV shows you didn't get to watch and would like to watch soon...) and queue the rest. Most of us have a 40mbps (or more) line and with a decent Usenet provider it should take about a month or so to re-download everything.
As a side note: The truth is that the 3200/4200 is a total overkill for people who just want to have a large array of disks to store their media files as it sits idle most of the time. I wish Netgear would release an 8 or 10 drive array for people who just need large storage without the CPU power and amount of ram of the larger units.
