Mobile Hard Drives comparison?

So, I'm considering upgrading my laptop's hard drive... but I'm not sure what's most ideal or what I'm looking for in a HDD. (In desktops... I just check for the one that fails the least. XD)

So... now I need to consider things like power consumption, heat generation, capacity, etc...

I'm not overly concered about capacity, however, I do care about battery life and access speeds, and I hear that capacity and access speeds do go hand in hand somewhat.

If I were to buy a mobile HDD to upgrade the drive in my Z, which would be best for optimizing speed while minimalizing heat and battery drain?

Also... what's the best 7200 RPM 2.5" HDD? I'm looking for something with very low heat generation ideally to stick into my PS3 (1st gen, yay backwards compatability, but it gets pretty warm... don't want to make it any worse).

Many thanks in advance for any help.

 

Here's a big test of the most new 2.5" HDD's out there.

About losing batterylife, i don't think you'll have to worry about that with a new drive as they draw less power than the older 2.5" drives, though it won't make a noticeable difference if you don't have a batterytime of like 6hrs+. And keep in mind, with a faster HDD you can access things faster and do things faster = saving time.

 

Hmm... that was pretty useful in terms of 7200 RPM drives... but sadly didn't have anything about operating temperatures. T_T

Now to find 5400 RPM comparison articles to compare those 7200 RPM drives to 5400 RPM drives.

 

You said 7200rpm so i gave you a 7200rpm review
Temperatures are normally around 40 to 48-50C with all those as i've seen. New HDD's aren't likely to get overheated or such.

5400rpm drives are about 25% slower and power consumption is negligable, really.

 

A bit of real life info.

I updated the 250GB 5400 SATA1 WD drive that came in my Asus G71V to a WD 320GB 7200 drive and it netted me about 10 mins extra run time and slightly lower temps. Seems weird but the newer 7200 drive is more power efficient (newer bearing styles to reduce friction, better IC's and head positioning logic etc) than the old 5400 it came with.

 

I see you are concerned with heat and noise. WD5000BEVT is probably your best choice.

Seagate 7200.3 is a bit faster but also more prone to cause heat, vibration and noise.
