I posted on the compatibility thread asking if there was official compatibility before I found this thread. Wondering if anyone has had any problems with these drives? FYI, ZipZoomFly.com has them for $179.99. Was going to order 4 and upgrade all my 750GB drives.

I'm still awaiting an official answer myself...

I think so far, we're all waiting for an official answer....I have 2 drives...was going to put one in my Drobo and one in my ReadyNAS and see what happens

I don't know about offical compatability, but the 3 Seagate 1.5tb drives in my system didn't work until I upgraded to the latest firmware, and now I have three 1.5tb drives that work perfectly. Have written and erased a tb of data a couple of times with no issues. getting a 4th drive tomorrow and will see how the expansion goes.

Kudos for getting an updated firmware out so quickly to support these drives!

Anyone yet successfully loaded four ST31500341AS 1.5TB drives into a Readynas NV+ and obtained a fully operational ~4.5TB xraid drive?

Does not look like it yet... Any capacity "screenshots"? I'm curious to see what the max capacity and (typical/max) drive temps are under xraid! Hopefully these drives are faster than the green power drives which seemingly cannot suspend-but it's no big deal really to me.
Currently weighing whether to go with 1TB GP drives or try these new 1.5TB drives...

Dare I ask if the 4 disk array can sleep and resume on demand <ducking> as those drives must suck down the juice to all spin 24x7

the race is on....thx!

We just placed them on our compatibility list. We still however need to place a note indicating that firmware 4.1.4 or newer is required to use these drives.

I purchased a new ReadyNAS NV+ a couple of weeks ago with 2 750GB drives. I kept it in X-RAID and loaded ~100GB of data onto it.

Then I purchased 3 of the Seagate 1.5TB drives. I added two in the two empty slots and it went for hours to initialize them. I then took out one of the 750GB drives and replaced it with my third 1.5TB. All was according to what I expected. The Volume Settings page showed 1 698 GB Seagate with 694 GB allocated and 3 1397GB Seagates with 694 GB allocated. All my data was there.

I then removed the 1 smaller drive (in slot 1) and after rebooting several times it's still not understanding that it's supposed to expand. It shows:

Disk space: 101 GB (4%) of 2076 GB used
Additional 5 GB reserved for snapshots

Configuration: X-RAID (Expandable RAID), 4 disks
Status: Not redundant. A disk failure will render this volume dead.
RAID Disks:
Ch. 1: UNKNOWN [698 GB]
Ch. 2: Seagate ST31500341AS [1397 GB] 694 GB allocated
Ch. 3: Seagate ST31500341AS [1397 GB] 694 GB allocated
Ch. 4: Seagate ST31500341AS [1397 GB] 694 GB allocated


Does anyone know how to make it forget about the fourth drive and give me 3 1.5 X-RAID drives for ~2700 GB?

Thank you.

I have.

I was having a problem about a day after the installation where I couldn't delete a file. I decided to reboot with a file/quote check and that failed with a kernel panic. I restarted and it proceeded to do a resync and has been fine since. I did notice a sector reallocation on one of the drives, which I presume was the cause of the problem.

What you've done is broken the array. You've expanded to 4 drives by placing the additional 2 drives in the two empty slots. You should have replaced the 750GB drives 1 at a time.

You cannot move from 4 drives to 3.

You have two options:

1) leave the 750GB in and do without the additional space the 1.5TB drives give you.
2) buy an extra 1.5TB to replace the 750GB you've taken out.

Actually, there's a 3rd option which you probably won't want to do - blast it and start over, losing all your data on the drives. Backup first, reconfigure, restore.

Wow! bollar you have given me the new drive to stash away $800 for these four drives, and then swap them in one at a time into my existing 4TB WD Greenpower array.

4.163 redundant Tb.. sweet. Thanks for the thorough report...

Is that normal to see te 4Gb discrepancy per drive -- [1397 GB]vs. 1393 GB allocated ?

What kind of drive temperatures do you see at idle and under higher load? That was my (and dare I say others') last basic curiousity...
