Why this HD is so cheap?... overheat concern

I am going to upgrate my Acer 5672.

On tigerdirect I found 2 nice Hds

Seagate Momentus 7200.3 ST9250421AS 250GB Mobile Hard Drive - 2.5", 7200RPM, 16MB, SATA-300 for $74
and
Hitachi / TravelStar 7K200 / 200GB / 7200 / 16MB / 2.5" Mobile / SATA-150 / Hard Drive for $90

It seems to me first one is much better, more size , more speed, but I don't understand why it is cheaper.

One guy told me Segate's disks overheat laptops. Is it true ?....

So... why is it cheaper? I everything ok with this brand ?

I am also planning to add more memory, 4GB instead 1GB.

Should I be concern about overheat ?

Thank you

 

Seagate 7200.3 have no more a tendency to overheat then hitachi's or western digitals.

As for being faster, it is the same physical size as the Hitachi as well as being the same speed (7200). It does however have more space. (200 GB vs. 250 GB)

The Hard drive market frequently fluctuates in prices. That Hitachi seems unusually expensive however. I am sure if you look around you can find that Travelstar for much cheaper.

As for brands Seagate is the largest manufacturer of HDD's in the world.

Personally, I love Seagates, never have had an issue with them. I have had issues with Toshiba's. WD's are also great hard drives!

As for your RAM situation.

You will not benefit from 4GB of RAM unless you are running a 64 Bit OS. Ex. Vista 64 Bit or XP 64 Bit although the previous is much more likely.

A 32 Bit OS, which is most likely what you have, is only compatible with about 3.2ish of RAM. So why waste $ on an extra GB. Get 3 Gb of RAM. One 1 GB Stick and one 2 GB stick and you will be all set.

Hope this helps!

I meant
Data Transfer Rate on Serial ATA: Up to 3000 Mb/sec for Seagate and
Data Transfer Rate on Serial ATA: Up to 1500 Mb/sec for Hitachi

I read on the Internet that 2GB*2 is better than 1GB+2GB, even for 32 Bit OS, because 2GB*2 will be "dual-channel configuration". I don't know it is true or not. But anyway if I don't get problems with 2GB*2 configuration,
OCZ 4096MB PC5400 DDR2 667MHZ SODIMM Memory (2 x 2048MB) for $34 is not big deal...

 

The dual channel benefits are hardly something you will be able to notice performance-wise.

 

those are interface speeds, and your drive would only see those for extremely short periods (bursts).

The Seagate has higher areal density so it should have a faster data transfer speeds, all things being equal (which they are not).

The Seagate might be going cheap because of the impending release of 7200.4 model. I know I picked up the 320GB 7200.3 last month for around $80.

2+1GB in dual channel will run the first 2GB in dual channel and remaining 1GB in single channel mode.

 

I have always found Seagates to be reliable HDD. No problems here.

Have had WD and Fujitsu fail though.

Always bear in mind your Acer 5672 was always(is) a "hot lappie". Shoving a 7200 RPM drive in there is going to warm things up even more. Personally, I would rather buy the biggest 5400 RPM you can afford as a 5400 RPM drive runs cooler than a 7200 RPM drive.

Just something for you to think about.

 

Dual Channel is truly a thing of the past. Perfomance increases are NEGLIGIBLE and in synthetic benchmarks will come out to around 5%+.

I agree ^^

Been thoroughly discussed before. Dual channel is not a thing of the past, dual channel has 10-30% improvement over single channel. What you probably mean (as the OP is interested in) is synchronous vs. asynchronous dual channel. This gives differences less than 5%.
