As already mentioned, the VelociRaptor interface was upgraded to SATA/300 to sustain the drive’s high throughput of almost 125 MB/s and the interface bandwidth of close to 200 MB/s. This is the highest throughput we’ve measured in our storage test lab. However, the VelociRaptor not only provides excellent throughput, but is also capable of sustaining higher minimum transfer rates than most other drives. The minimum transfer performance is crucial for applications that rely on constant data streams and it becomes important once you fill the entire 300 GB. Here, the new Raptor doesn’t drop below 77 MB/s with the exception of a spike during our test (which can happen for various reasons). This is clearly more than most of the high-performance Flash-based Solid State drives can provide - and those aren’t available at more than 128 GB per drive yet.
Application benchmark results are excellent, though the VelociRaptor is beaten by Fujitsu’s and Seagate’s SAS drives in the Windows XP startup benchmark. A look at the I/O benchmark results makes very clear that those SAS drives still are the crème de la crème when it comes to I/O intensive server workloads such as file servers or web servers (10-50% more performance for the 2.5" SAS drives), databases or workstation applications (up to 100% more performance with 2.5" SAS drives). However, these differences are only important in server scenarios, where lots of concurrent commands are pending.
If you look at the benchmark section it becomes obvious that it was time for WD to move, because many 7,200 RPM drives had outperformed the old Raptors by a significant margin. Although this is only important for desktop applications, the old Raptor was about to pass into obsolescence, since 7,200 RPM drives today offer up to 6x the capacity and at least equal performance at more attractive price points per gigabyte. The VelociRaptor returns the Raptor line back to its previous dominance in the desktop world. For desktop applications, the Western Digital VelociRaptor is the fastest SATA drive available. But there is more to consider with the new drive thanks to the 2.5" form factor.

Athauglas......on page 5 is the drive with the top plate removed..not with a clear window.
*drools*
Very nice and about time. Now, who has $300 to lend me.
LAME as all hell...mant new 320gb/platter drives are almost as fast with a lot better capacity and surely price.. ! This is like a raptor ME edition...zzzz
#1 - Finally! Tom's Seems to have gotten a scoop. It's been a while but it's nice to See Tom's have a major hardware review out before the others.
#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.

Oh really, which ones?

Seagate 7200.11 (if they can work out their doa prob):
http://www.newegg.com/Product/Prod [...] 6822148316
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.
My bad, 300 gb does make it look beter ! but still those other drives are way to close considering this is the raptor series.
Well you answered it yourself i.e., seek and IO. You can't take read / write as the total picture. The drives you posted aren't really that close in read / write either. I'm sure you know the last bit of performance costs the most money.
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.
Seriously. Just what about this drive isn't impressive?
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.
Honestly, who was expecting the next Raptor to be a 2.5 inch drive? I know it's in a 3.5 inch enclosure, but you just know the guys at Alienware are trying to figure out how one of these is going to work in a laptop.
About time they updated the raptors, they've been doing pretty poorly for quite a while. It's cool to see over 120MB/s read/write on a desktop drive.
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?
They look like a really nice answer to SSDs. I'm really considering getting one but $300 for a hard drive is a lot of money.
Hell, it'd be the most expensive component in my rig...

Notebook HDs only need 5V and the velociRaptor needs both 12V and 5V. I'm not saying it can't be done.
It's not sour grapes...it's spoon feeding us tiny bumps and calling it amazing that gets me...it's better, but amazing or wow or making a big deal about an incremental increase is just hyping it up, when it's not that big of a step up.
Lets see how it looks to me:
- 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
^My wallet says I have to live with my Raptor, you know bills and stuff.

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.
This drive looks good to me. If I hadn't just built a new computer, I'd like one of these in it. One might end up in the new computer anyway. Don't know, will see.
Hey wait, that government rebate check could pay for one of these and not hurt the wallet at all.
look up a hard drive from back in the day called a Chinook. How about some real innovation...I'll gladly pay out the nose for some.
2 actuators is better than one and not at all infeasible today.
