Hi

The model name of the latest WD Green 3TB drives which use 1TB platters is WD30EZRX-00DC0B0.

Does anyone know the equivalent for the Green 2TB drive?

Thanks.

Archive of platter densities
This site is excellent, the guy keeps it updated with various drives and their known platter/head count.

3TB EZRX appears to be 750GB/platter
WD has been slow to move to 1TB/platter
the red series are all 1TB/platter however

Is there even any evidence that 1tb platter drives are any more reliable?

I don't think the WD Black 1tb and 2tb's have this, and they have the best track record and longest offered warranty of all consumer hard drives on the market.

If anything higher density platters could be less reliable(maybe somebody can quantify this for us). Higher performance and total capacity is what interests me most assuming the reliability is atleast similar.

in a perfect world 1TB platters would be more reliable since it's the max platter size being made and therefore the drive would have to pass testing all the way through to sold. i remember hearing smaller sized drives can used binned platters from larger drives and in my mind those drives would be less reliable.

I wonder why we dont see any 4T or even 4,5T or 5T drives from WD yet.
They should have the technology to produce them. Maybe to make more money of the existing series..

Anything else on there useful?

I think the manufacturers have run into a wall on track seeking. The 1T platters have tracks so narrow the heads have trouble homing in on them. WD's forte has been multi-threaded IO performance and small random reads and writes. These suffer greatly from slow seeks and WD is thus, loathe to release a "performance" drive made with 1T platters.

Hitachi is talking about a hermetically sealed drive filled with helium to reduce the buffeting that heads take. This should make track seeking easier and greatly reduce power demands. I have no idea when they'll release it, but they're talking about a 7T seven platter performance drive.

Yee hah :biggrin:
