Introduction
Western Digital have just released the 500GB 2.5” WD5000BEVT and Overclockers.co.uk were one of the first suppliers in UK to get stocks. This is the first 250GB per platter 2.5” HDD to reach the customers. Other manufacturers have released 500GB 2.5” drives, but they have used 3 platters. How does this new HDD perform? WD is also claiming new features such as WhisperDrive and Intelliseek, which claim to reduce power consumption and noise.
I first tested the WD5000BEVT in an Icybox enclosure with eSATA port so I could also measure the power consumption (after making allowance for the power consumed by the enclosure). Other tests were carried out after installation.

The WD specifications do not include the disk-to-buffer transfer rate which is one of the key performance indicators.
HD Tune
I used the HD Tune Pro trial so that I could get both read and write test results.

After installation in the computer I reran the normal HD Tune test, this time setting the CPU to maximal performance in RMClock (which sorted out the apparently high CPU utilisation - evidently calculated relative to current CPU speed)

HD Tach
Another popular hard disk benchmark. See how the WD5000BEVT compares with my current Fujitsu MHZ2320BH. This test using the enclosure.

Power and Temperature
What doesn't show in those results is the power consumption. My meter was reading no more than 0.61A during the benchmarking. The enclosure without the HDD uses 0.09A which means the HDD is pulling 0.52A. At 5V, that means 2.6W (which is consistent with the specifications). In contrast the Fujitsu MHZ2320BH uses at least 0.15A (0.75W) more power under the same conditions. The lowest power consumption I have observed for the WD5000BEVT is around 0.1A (=0.5W) which is similar to the other HDDs I have measured.
The other indicator of lower power consumption is the actually drive operating temperature. Now it is installed in my Dell E6400 I am observing a temperature of 37 to 38°C, which is 2°C lower than I was seeing yesterday with the Fujitsu MHZ2320BH.

Conclusions
Western Digital have provided an excellent combination of increased capacity, better performance and excellent power consumption. While the transfer rates do not beat those provided by the 320GB 7200rpm HDDs, they are comfortably ahead of the other 5400rpm HDDs. The access times are also good and power consumption excellent.

Very interesting read John. Good work by WD, the acces times are lower than the WD3200BEVT.
The transferrates are not as high as posted here: http://forum.notebookreview.com/showthread.php?t=305890&page=3
Maybe something to do with the CPU utilization?
If you could run PC Mark 05 in XP I would appreciate it. -
Pretty good scores, but the HD tune score is kinda low. Wasn't what I expected.
Thanks for the review John. -
awesome!
where did you get the hard drive from? -
Han check out the scores posted by kaltmond here.

John, thanks this is great stuff. I never really knew hard disks could be tested this way.

Awesome drive, I think one of these will find its way into my EEE when they become cheap.
May find some of the black editions in my G50VI love WD drives.
Id assume with only 2 platter its the same size as the standard 2.5" drive and thus no compatibility issues like other larger drives suffer in some notebooks. -
Nice HDD. Waiting for the faster 7200RPMs.
-
John Ratsey Moderately inquisitive Super Moderator
I'll be running the PCMark05 tests once I get the HDD installed internally (I'm planning to clone my present HDD overnight).
For a change, the UK seems to have got a share of the product launch, rather than several months later (that HDD is less than two weeks old).

Wow, the benchmarks are nice. Its not outperforming the 7200 320gb drives, but for the capacity its really impressive.
Kamin likey
Thanks for the review. I cant wait until they are more readily available -
John Ratsey Moderately inquisitive Super Moderator
I have updated the original post with more information.
I have also moved the graphics to another server. I am having trouble today seeing the images I posted using FreeImageHosting.net yesterday.
The fix for the apparently high CPU utilisation in HD Tune is to set the CPU to maximum performance. It appears that the program calculates the utilisation based on the current CPU speed which, by default, is in the SFFM mode.
John -
Thanks for the PC Mark results.
-
I guess I don't have to goto the trouble of benchmarking my drive now, you beat me too it, nice results.
Mine does feel as fast as the 7200rpm scorpio black in my wind, although in reality it probably isn't, but not by much though. -
I guess the 500GB comes with a 3year guarantee compared to the 5years of the 320GB bekt, right?
That's a problem, along with the price.
In my country the 320GB bekt costs 80euros now.
The 500GB bevt hasn't appeared yet, but I really doubt it will cost less than 140euros -
There have been 2 now. One showing a maximum transferrate of 86 mb/sec, the other 79,6 mb/sec.
-
Question if you had three of them in RAID 0 would it the AVG read/write be
61 * 3 = 183 AVG read/write for the RAID? -
I wonder if the new WD 400GB drives use the same platters, just limited to 200GB?

Hmm ether seagate makes a killer 250gb drive or something is going on lol. I just ran HDTune on my EEE with a Seagate Momentus 5400.4 5400rpm drive and got really good results. I need to find valid WD Black scores now to compare too.
Cpu usage low too, and this is on a 1.2ghz single core atom. -

I'm picking up two of these bad boys for my dell 1720. Going to be upgrading my CPU soon as well.
Can I get some help finding this product? I was looking through reviews from overclockers and they all seemed to agree that they had terrible customer service and none of the buyers recommended using overclockers. So needless to say, I will not be purchasing from there. is there any other site that has this HD? -
ViciousXUSMC Master Viking NBR Reviewer
I may get the time to run some benches later, if you want I can make a separate topic, like a mini reivew of my hdd and then we can just cross reference. -

Edit: I don't know if they offer better service, but they have them in stock. -
John Ratsey Moderately inquisitive Super Moderator
However, when I ordered my WD5000BEVT late last Thursday it had not shipped that day. On Friday I saw the price had dropped so I emailed customer service who adjusted the price on my order.
Another UK source is Dabs.com. Or there's span.com.
John -
I guess I'm just going to have to wait until it's over here in the US. Those two sites didn't ship to the US unfortunately. It can't be too much longer before it comes over here so I'll just be patient.
-
vicious, run sisandra, pcmark and such on the drive.
I have similar problems. On one system, my 7K320 will read 64mb/sec and on my other system with a hardware raid controller, it reads 145mb/sec.
Both drives are identical, yet their is a problem with many benchmarks reading certain systems.
Very good review John, you have a ton of benchmarks and comparisons.
+ rep, and good luck with the drive.
K-TRON -
Yeah, I've checked everywhere I usually get stuff from, and none are in stock yet. Hoping soon though!
As a side note, the Samsung 500gb drives have come down to $149 -
The samsung drive has three platters, while the wd has two platters. This means that the WD drive has a higher data density (250gb versus 166gb per platter). The WD drive will have higher data bandwidth because of that additional data density, so it will perform much better than the Samsung Hm500LI
K-TRON -
why we even bother to run benchys for hard drives, i never notice performance or power consumtion diference between brands.
-
yep, agree on all fronts, hence why I'm waiting for the WD... but, last time I checked the Samsung was still over $200. So, depending on what the WD costs, could still be a viable option for somebody simply looking for space as opposed to best speed.
WD should be a better drive though. -

0.5W lower power consumption (my current best guess) is also significant if trying to get maximum battery time. It is 5% of 10W which translates to another 15 minutes in 5 hours.
John -
Review looks great .. the numbers look almost like what I expected.
John, can you tell something about the noise level? Since I had to turn my brand new 320BEKT into a backup drive (a real pity!) because it created too much idle noise I'm not sure what this new mammoth will doHow does it compare to the 320BEKT or the 250BEVT? For now I have to stick to my Hitachi 7k200 (100gb single platter) which is a LOT more silent than the 320BEKT even though on paper it's the other way round.
-
John Ratsey Moderately inquisitive Super Moderator
Overall, I think the measures to control power consumption also result in less noise.
John -
-
How would you change the acoustic management?
Hitachi Ftools? Or is there another method out there? I tried using Ftools but it wouldn't let me touch the power management settings. -
Though my drive did alot of noises the first week, but it aint doing it anymore.
I suggest that you send the HDD for RMA? -
I just ordered a Western Digital Scorpio Black WD3200BEKT 320GB 7200 RPM SATA 3.0Gb/s Notebook Hard from newegg and I'm now depressed after seeing some good things coming from the 500GB
-

Funny, right now I'm using a WD3200BEVT and having previously tested a MHZ2320BH G1, the former seems to sip up much more power. I mean when on battery, the power consumption went as low as 12,7W (meaning over 4h of battery life) with MHZ2320BH but with WD3200BEVT, it won't go below the lower 13W`s (4h max). When downloading something, the battery life figuratevely halves. The only difference seems to be slightly better access times.
-
John Ratsey Moderately inquisitive Super Moderator
The Tom's Hardware tables show that the WD3200BEVT has a high power consumption. They appear to have fixed this with the WD5000BEVT which I are sure uses less power than the Fujitsu MHZ2320BH. In addition to my current measurements, the WD's operating temperature inside the computer is 2 or 3C cooler than the Fujitsu.

The 100GB I have right now are simply not enough, but I don't want to trade speed and noiseless operation for more capacity. I was thinking about the Momentus 7200.3 because I read reports that especially when idle it's not as loud as the BEKT. But probably I will wait for the Momentus 7200.4 to arrive end of the year. That baby as a single platter 250gb would be ok if it's silent.
Choices, choices ...
I wonder how big the noise difference between single platter and dual/multi platter really is. -
John, nice article ! well done.
too bad I bought a 2.5" Samsung 500GB already.... -
hey, just a heads up, NewEgg has these available now, $149.99
Just ordered one -
I've got 2 on order too. Will stick my Samsung's in some eSATA enclosures. Hopefully I'll notice an improvement in general system speed and noise levels
-
And IMHO, if you can withstand the sound until the end of the year with the BEKT, you're not that picky with noise i'd sayI'd throw it out directly if i am to change the HDD anyways.
