Western Digital Velociraptor 300GB SATA HD

Article Index:   

Western Digital's Raptor line of high performance hard drives has been a long-time favorite of PC enthusiasts since its introduction several years ago.  When WD's Raptors first hit, their 10K RPM spindle speeds allowed for much lower access times than the more common 7200 RPM desktop drives of the time, and overall relative performance was strong.  Many users were put off by the relatively low capacities of the Raptor, which debuted at 36GB and topped out at 150GB, but they were still wildly successful amongst enthusiasts regardless.

As time wore on though, Western Digital's competitors introduced faster and faster, high capacity drives, that began to out-perform the Raptor in a number of key metrics.  WD too released some fast, high-capacity drives that out-performed even the fastest Raptor in many scenarios.  WD released a number of more eco-friendly drives under their "Green Power" badge as well, which may have led some to believe WD's focus on the enthusiast sector had diminished.  However, as you'll see today, that is definitely not the case.

Today, Western Digital is unveiling the brand new Velociraptor WD3000GLFS 300GB hard drive.  Like the previous generation Raptors, the new WD Velociraptor sports a 10K RPM spindle speed, but the drives are actually quite different.  As you'll see, this new Velociraptor is simply in a league of its own, thanks to some innovative design choices.

Western Digital Velociraptor VR150 300GB Hard Drive
Specifications and Features

*Note:  MTBF now estimated at 1.4M hrs.

In a side by side feature comparison, the WD Velociraptor resembles the older Raptors. The drives share the aforementioned 10K RPM spindle speed, they have the same 16MB buffer, the same reliability ratings, and acoustic and environmental characteristics.  The WD Velociraptor's new design, however, offers significantly increased performance, both in terms of access times, IOPS, and data transfer rates.

We should also point out, that while the Raptor line and Velociraptor share the same acoustic specifications, the drives definitely do not sound alike.  With the new Velociraptor, the high-pitched whine emitted from the previous-gen Raptors has seemingly been eliminated.  However, the Velociraptor's heads can easily be heard chunking along within the drive.

 the name alone gets a +1 from me. would be nice if it had 32MB of cache as some other drives more than 2x their size do

I talked to WD about the cache size, and they said it offered little to no benefit, so they kept the buffer at 16MB. Obviously, it didn't hurt performance much!

Maybe it's not needed for 300GB hdd...

Anyways it looks sweet ;)

Wow, that thing flies.  I have a 300GB hard drive now, so I know how to work with that capacity.  But the price is pretty steep.  What I actually payed most attention to in the article was the WD6400AAKS which actually seemed to usually perform inbetween the old Raptor 150 and the new Velociraptor 300.  Considering it's great capacity and relatively low price, I may end up eventually going for that drive when I need more capacity, likely this summer.

Definately an impressive drive... its nice to finally see higher RPM drives break through that 150/160GB barrier thats been around for a few years.

nelsoncp21 6 years ago

yes very nice indeed. Wish these were out when I got my 150 raptor x's but they do just fine. 35% is a big jump though.

Nice review, Marco. That drive looks pretty crazy...a 2.5" drive in a 3.5" heatsink...very interesting.

Consider it dugg!

It's dugg. wow that article had 75 digs on it when I clicked.

I guess this unit will cost insanely much,but it does worth it since it is better than even some SAS drives

Good review. 

One additional comparison I would find interesting for these high-end hard drive reviews would be 'short stroking' a larger hard drive down to the size of the new drive being tested (300GB in this case), such as the 1TB WD included in the review.  'Short stroking' is when you only use the first part of a drive, reducing seek times and avoiding the lower performance inner tracks.  This is commonly used to 'cheat' in RAID or NAS benchmarks, though it can also be a useful tool for benchmarking when you are trying to push a RAID controller or NAS box harder.

I would expect that if you took the 1TB drive, and used only the first 300GB, you would get much better seek times and both read and write transfer speeds, and the cost can be lower than the Velociraptor drive.  I'm not sure how much performance you would gain, but when I've tested similar configurations in the past the improvement was significant.  Of course, you have to be disciplined to ignore that tempting extra 700GB since when you use it you lose the extra performance...

Interesting idea there, JSP... I know of this practice in the enterprise space but I'm not sure too many end-users have ever tried this. Sounds like a reasonable approach to performance though, taking advantage of faster access times on the inner portions of the disk.

 i just creamed my pants... ive long been a fan of the raptor and have one in my current rig. and was very sad to see current hard drives beating the raptor... now the raptor is back to being king of the castle.

imagine these in raid

one thing though, in the review you did not test raid of 2 150gb raptors (since 2 150 are somewhat the same price as the new raptor)  which would of been nice to see.

p.s. i posted this in the storage section of the forum for that thread but since the discussion is here imma copy and paste my post. hope you guys dont mind :-)

I did a tiny bit of math, and it looks like the tangential velocity (rim speed) of the 7200 RPM 3.5" drive (79170 in/sec) would actually be slightly faster than the 2.5" drive (78540 in/sec), so I would expect that a 300GB short stroked 1TB drive might be slightly faster than the 2.5" drive in data transfer (assuming the same bit density, which may be false).  Since the 3.5" drive has longer tracks, it should maintain its speed parity for the entire 300GB.  Track to track latency within the 300GB should also be slighly better (longer tracks, so fewer of them), but rotational latency would be much higher so overall latency I would expect to be higher.

This seems like a valid comparison, and a real option for some, since the 1TB drives are actually cheaper than the Velociraptor.  This points to a performance drawback of WD's choice to go with a 2.5" form factor for a performance drive (lower rim speeds).

ooo i would love to try that in raid 0, also digg lol 250+ nice

coolzonestefan 6 years ago

This drive is nice,I completely agree,it has outstanding performance,and will be a king till Seagate will launch the new series of HDDs like 7200.12.The 7200.11 was pretty close to the older version of the Raptor,much cheaper,much silent and a lot of space for storage

This drive is definatley one I would consider for my new system!
