Western Digital's VelociRaptor 10K RPM SATA Drive 250
MojoKid was one of a number of people to submit about WDs new 10k RPM SATA Drive. He says "Western Digital's Raptor line of Hard Drives has been very popular with
performance enthusiasts, as a desktop drive with enterprise-class performance.
Today WD has launched a new line of
high-performance desktop drives dubbed the VelociRaptor, and the product
finally scales in capacity as well. The new SATA-based VelociRaptor weighs in at
300GB with the same 10K RPM spindle speed, but with one other major
difference — it's based on 2.5" technology. Its smaller two-platter, four-head
design affords the VelociRaptor random access and data transfer rates
significantly faster than competing desktop SATA offerings. Areal density per
platter has increased significantly as well, which contributes to
solid performance gains versus the legacy WD Raptor series."

The review only compares the new drive to older models from the same manufacturer, and it turns out to be faster - duh. How does the performance compare with those expensive solid state disks that are starting to appear?

When spinning up from a cold start, the WD3000BLFS maintains its prowess with a very economical showing on its 12V rail. At just 9 watts, the VelociRaptor weighs in a full 6 watts (66%!) lower than any other drive SR has ever encountered.
I think the heatsink is mostly for show, and to make the drive fit into a normal case. Still, it would be nice if they made it easily removable.

What you want to know is idle and seek power for the VelociRaptor which is 4.2/6.9W. The 3.5" WD GP has an idle power which is lower at 3.8W and a seek power which is higher at 7.6W. What you can see from the charts is that the VelociRaptor is indeed low powered compared to most drives and should only generate marginally more heat than a 3.5 WD GP.

As it is, the 2.5" server drives do get faster access times than the closest 3.5" drives of the same RPM, I think in part because the head arm is shorter (less rotational inertia) and doesn't need to swing as far. Higher areal density helps get higher transfer rates.

I was able to find some graphs with HDD failures broken down by manufacturers. The difference between Seagate and WD is a whopping 0.48 percentage points. This might or might not be statistically significant, as no additional information is available. In any case, it's far from impressive. Here's the graph in question. [sunrise.ru] It's based on RMAs from a PC equipment stores, and the whole thing is available here. [sunrise.ru] It's in Russian, but the text doesn't say anything which isn't on the graphs.
I'm not taking this personally at all, and I have no stake in WD whatsoever, only in truth. This probably sounds way too cheesy, but that's what it is. Between the laptops, which mostly came with Hitachi drives, and a bunch of Seagate and Samsung drives in desktops, WD drives probably don't even make up the majority of all HDDs, and that's the only connection I have to WD. Do you work for Seagate, by the way? So far, I'm the only one who tried to use actual numbers and cited any sources (even if you don't like them), so the ball's in your court.

I suppose this might have been different in the past, though judging a hard drive manufacturer purely based upon anecdotal evidence is a bit flimsy. There are people who say the same thing about every single other hard drive manufacturer out there.
I'll wholeheartedly agree that there can be bad batches of drives (which is most likely what you encountered), though any faults are usually rectified quickly enough that there doesn't seem to be all that huge of a difference across manufacturers when you look at the entire population.
If you've ever managed a computer lab (eg. large number of identical machines), you'll occasionally run into a batch of machines with particularly dodgy power supplies, hard drives, etc..... More interestingly, if you've got a large sample of "identical" machines that were ordered in separate batches, you'll also likely find that the patterns of failure differ somewhat between the two batches.
The only exception to this is that server/enterprise-grade drives tend to be more reliable then their counsumer-grade counterparts. This is why they cost (a lot) more.
