Seagate Momentus 640GB 2.5" Hard Drive ST9640322AS

Thanks everyone. Im going to pass on this seagate. Will wait when Western digital puts on their unit which is alwayss better and faster than seagates laptop drives.

 

Someone who also has this HDD? Have a little question about that.

 

Nice, so the 7K200, which is a good 3 years old is faster than this new drive from seagate
Tisk, tisk. Seagate really needs to get back in the game with performance.

K-TRON

 

embarrassing.

 

I see WD 640GB benchmarks, similar to Seagate.

 

Another poor Seagate performer, I would wait for the Hitachi 5K640, the 5K500.B have the same speed as this 640GB model taking in fact the Seagate has more aereal density than the Hitachi.

 

Where do you see this??

 

Where is the link?

 

Here is HDTune test of my Seagate 640G in ODD Bay and WD 640G from others.

 

Incorrect by scientific standards. The WD result is not accurate.

 

And synthetic benchmarks don't tell the real story. If we're going to rely on synthetic benchmarks it should include the random and small reads like page 2 of HDTune Pro and CrystalMark.

The WD 640GB will most likely beat the Seagate 640GB in real life performance.

 

The WD's transfer rate results are disappointing compared to my above Fujitsu drive (250GB/platter, 5400RPM) Almost no improvement! I wonder if the tested WD6400BEVT was bottlenecked in some way.

 

Well obviously. Anytime you see Chinese lettering you know it is not accurate information. You simply have to wait till they go on sale and view results from real people.

 

If sequential read speeds meant a lot the Seagate 7200.4 would be way faster than a WD3200BEKT. In real life the WD3200BEKT beats the Seagate 7200.4.

Why? because of acces times, IOPS and random read speeds.

Crystal Mark and HDTune page 2 provide better benchmarks.

 

Phil,

When I bought the Seagate 7200.4 500GB model to replace my Hitachi 7K200 I thought I had screwed up the install of Vista x64. When I re-installed the Hitachi and the performance doubled, I returned the Seagate thinking I got a defective one.

I repeated this three more times until I finally gave up on the Seagates (I returned 4, Seagate 7200.4 drives). What replaced it was the 500GB Scorpio Blue 5400rpm drive. Yes there are times when the Seagate was faster, but overall the system doesn't pause (almost freeze) like it did with the Seagate - and I still have the extra GB's too!

I will not even consider the 640GB Seagate and although the benchmarked performance of the 640GB Scorpio Blue looks bad - this is the drive that I'm interested in - unless Hitachi is going to bring a 7K640 version soon (or I get an SSD, heh).

I long ago found that benchmarks meant very little to how a drive 'feels' when using it - I wish reviews would focus more on that aspect than the simple benchmarks they post.

I really believe that Seagate tweaks their firmware to 'bench' impressively, but they do that at the expense of real world performance in actual O/S's.

So, anybody else care to post their upgrade experience from their old to their new drives as to how the O/S responds (feels)?

 

Well I agree synthetic benchmarks don't mean much. But there are many real world benchmarks out there that do give an accurate impression of the HDD speed. Like the WorldBench benchmark Techreport.com uses. Or the file copy benchmarks.

 

EErrrrrrr.... there are ZERO benchmarks on the internet of the 640gb scorpio. The screenshot of the results with asian lettering are false. Anytime you see asian lettering it should be common knowledge to dismiss the results.

 

I just got this for free. It may not have the best performance, but I'm not complaining.
