Data Transfer Rates
Read Data Transfer Rates

Look at this! The new VelociRaptor even outperforms the Seagate Savvio 15K.1, which is a 2.5" enterprise hard drive, but based on SAS and 15,000 RPM.
Write Data Transfer Rates

Write performance is mostly similar to read throughput. Minimum write throughput is better than the results we received for the read benchmarks because the benchmark run didn’t suffer from the spikes we found after doing the read benchmarks, which can happen due to drive recalibration, physical interference or due to firmware intervention.

#2 - A very well written article. I've noticed an uptick in the quality of articles of late. Kudos again.
#3 - A very nice HDD. Something I may definitely look at adding to my system.

Seagate 7200.11 (if they can work out their doa prob):

A few of samsung's F1 spinpoints...
they are all pretty close, especially seagate at 114mb STR, 60 low and around 100 average across 320 gigs.
A 150 gig drive that is just a bit higher is not so awesome, and yes I know seek times, IO and all that matter too. Do you really thonk the new raptor is gonna be 90 bucks like these, I sure don't.
If they at least have a 320 same performance, or the performance was closer to 150 (as in a larger 3.5 platter), then sure, but it's sad considering a 7200 is almost passing them ALREADY.
You could say you don't think it's worth the cash, I have no problem with that, but it sounds a lot like sour grapes to me.
It has twice the storage space of the previous top model.
It has better benchmark results.
It runs cooler way cooler.
That IcePack is perfect for mounting behind front intake fans(improved airflow).
I'd want 1 over any 1TB drive. The price is also quite reasonable for a Raptor.
I'd call that progress in every way.
There's just no pleasing some people.
I wonder why I/O performance isn't as good as the SAS drives even though it has faster read/write speeds and latency. Could this be fixed with firmware?

Notebook HDs only need 5V and the velociRaptor needs both 12V and 5V. I'm not saying it can't be done.
- I get 30%+ of performance increase compared to my 1TB drive (yah, 10EACS)
- I get 300gb for $300, I already have 1000gb for $300
- I can get 640gb instead of 300gb with little speed decrease but it will cost $130.
So 30%+ speed increase equals almost 5x price increase? My wallet thinks otherwise... But thats my wallet, if your wallet says otherwise, I think you'll be happy with the new HDD from WD

Hard drives have to live within the laws of physics and current technology. Maybe you know of some way to get a 200% improvement. By all means share it with us.
