Replcing failed diisk
I've had my readynas nv+ (sparc) for about six years now. Couple of years ago replaced the original 500GB drives with Seagate 2TB.
Although they seem to be the same make/model as those causing http://www.readynas.com/forum/viewtopic.php?f=24&t=63698 I don't think that's the problem I'm having.
My problem manifested itself when the music I was playing (squeezebox, although I don't run the server on the readynas+ as it's simpy too slow) and I discovered the box was virtually seized - I say virtually because it would respond to a ping, but the web server didn't respond and no attempt to get at the data succeeded.
I had to power it off. After the restart and resync I got email telling me that there had been 365 ATA+ errors on drive 3 (I'm assuming they're numbered from left to right).
When I tried to play the same file again, at around the same point - same symptoms.
This time after the reboot/resync the email told me there had been 8751 ATA+ errors on drive 3.
So, I'm thinking drive 3's time has come.
From reading around the forums it seems that the WD Red drives are a pretty good bet.
So forgive me for asking basic questions: I know there is no problem installing larger drives (I'm using X-RAID); I'm thinking I might as well put in a 3TB drive.
Do people have good experiences with the WD Red (3TB) and is there any downside to mixing disks from different manufacturers?
thanks.

- Oh, I see the compatibility list doesn't mention the WD Red 3TB, only the 2TB.
And I suspect the old disks are 3GB/S and the WD Red is 6GB/S.
Is this likely to be a problem?
The sparc products are limited to 2 TB. They don't support GPT formatting, so 3 TB cannot be used.dgrb wrote: Oh, I see the compatibility list doesn't mention the WD Red 3TB, only the 2TB.
No. The SATA hardware in the controller and the disk will properly negotiate the speed. And in any event, only SSDs can saturate a 3 GB/s interface.dgrb wrote: And I suspect the old disks are 3GB/S and the WD Red is 6GB/S.
Is this likely to be a problem?- Thanks, 2TB it will have to be.
- Yes.
Note I revised my previous answer - I edited too much of your second question. 6 GB/s SATA specs are fine - my "No" was in response to "is this likely to be a problem?"
