The last thing that I needed was another pair of these since my new build is already over budget, but this is a great price for the retail box (5 year warranty). FWIW I have 9 of these, they run cool and are low power.

It's worth a lot.  So you have 9 2TB 5900 rpm drives? 

Isn't the Seagate 5900 rpm drives a cheaper cousin of the 7200 rpm disks? Is their much of a price difference in America between the drives? Interesting, I can't recall seeing these 5900 rpm drives in Oz.

Well the Seagate 5900 rpm drives are supposed to be equiv to the WD green drives. 

I think they're supposed to be a little bit faster. Seagate went with 5900 rpm (compared to WD's 5400 rpm) to claim the performance crown in the "green drive" realm.

I do. None DOA, nice and quiet operation, solid drives all around. With 9, the last parity check speed was: "Apr  1 06:51:12 Media kernel: md: sync done. time=24671sec rate=79182K/sec", and that was with some reading and writing going on during the check. I'm not sure why they're not very popular here; perhaps it was the Seagate 1.5TB debacle turned people off Seagate entirely.

There are lots of reported DOA.  But I'm reading about them and it's possible that they are more sensitive to good psu power then the 7200 drives.

So could you post more info about your server (I'm assuming all the drives are in the one machine). 

so they run at a lower rpm to reduce noise, in competition with the Western Digital Green disks. I have one of these WD disks for my HTPC and compared to my Seagates in my unraid server it is a lot quieter. The standard Seagates running at 7200 rpm seem a little, especially when you have 8 of them powering on and off at the sane time. When their reading/writing their ok, you can't really hear them at work.

I believe the slower rpm is to reduce power, like the WD green's.

So you would have to trade speed over noise? I'd rather a slightly noiser rig and have it running at optimal speed that a quieter rig and it runs a little slower. I'd like to see benchmarks from the 7200 rpms bs the 5900 rpm seagates, running in the same circumstance and setup and see whether it would actually make a difference using one disk over another.

Noise isn't an issue with either.  And it's not the crux of the discussion.

Here is one post where the problem was identified to be the psu.  I lifted the following review from newegg.  Most unRAID builds have plenty of psu power. 

 

Pros: Big, reasonably fast

 

Cons: It seems to be sensitive to a weak 12V rail

 

Other Thoughts: Shortly after installing it, I started to hear clicking. I thought the disk was failing. Movies were slow, directories would show slowly in Windows

 

I got an RMA# from NewEgg and I was ready to return the disk. Before I did, I tried in a different computer, and surprisingly, it was working fine. No clicking, no slowdowns

 

Back to the main computer, I changed the SATA power from a shared SATA power line to molex in a different power rail. The clicking and performance problems went away

 

Later I changed the power supply, and the disk is back in a shared SATA power line, working fine

 

At least for me, the problem was not the hard disk, but weak 12v supply in the SATA power connector. Other people may be having power problems too, as they add this disk to an already loaded system
