Thats annoying.

If you want noiseless then you want WD green drive if you want performance then get Caviar Black.
 
I'd also like to mention that a 1TB drive is probably better price/GB right now depending on which line of hard drives you are looking at.
 
^ agreed. Last night i discovered that i can get a 1.5TB Seagate at 10GB/$1 CAD vs 8.33 for a 1TB. ;)
 
You can't kill 2 birds with one stone.

Noiseless - Western Digital Green drives
Speed - Western Digital Black
 
im in the same boat. staying away from seagate so i guess its either WD or samsung.
 
Bad time to choose 7200.11 Seagates, steer clear for the moment cause it seems even the updates on the major issues are causing problems.

I bought a Caviar Black myself for sheer performance (WD6401AALS).

Depends on your definition of "noisy." I haven't heard a noisy 7200RPM drive since I had a crappy HP computer back in 2001. Compared to the Raptors, any 7200RPM drive is quiet in my opinion.
 
And what about WD RE3 , is it noiseless?
is many difference between RE3 & Black Caviar? (Price,noise,speed,...)
 
The RE drives are only meant to go in a fault tolerant Raid array. Hence the Raid Edition naming. They should not be used in a stand alone or RAID 0 situation. The reason is that they have a system on board called TLER. Basically what TLER does is limit the onboard error correction to 7 seconds. Any serious errors are then handled by the RAID array.

You can read up more on it here.

Single drive not needed, but I'm gonna have to disagree on the R0 point Don.

For me my controller was dropping my 2x640 R0 array because I had TLER disabled....when I enabled it, it works much better.
 
Read the Wiki article.

If you run an array without data parity like R0 with TLER enabled, you risk corrupting your data.

TLER limits the on board error recovery of your hard drive to 7 seconds. It then reports the error to the controller and the controller takes care of mapping the error. If the Raid does not have data parity, it cannot correct the error.

When I got my Thecus N5200 last year, I stocked it with 3 WD 1TB GP desktop drives. TLER was off. During the initial building of the RAID 5 it dropped one of the drives as unreliable. I ran the drive diagnostics and the HD Tune error scan and everything checked out fine. I started to build the array again and the same thing happened.

It tested fine again, but I RMAd the drive anyway. When I got the new drive in, I enabled TLER for all 3 drives since it was in a RAID 5 array, and they have worked fine since, about 6 months now.

Here is the WD data sheet on TLER. TLER Data Sheet While they do not specifically mention RAID levels, they constantly mention the parity and error recovery of the RAID. RAID 0 had no parity or ability to recover from a data error.

By all means, run your drives any way you want. But TLER without parity is asking for trouble.
