Haven't done much with 2.5" drives but looks as if I will be doing an upgrade to a Dell Vostro soon.

I see that these 2.5" drives are available with 7200rpm. Are there any ramifications (apart from extra cost!) to subbing a 7200 when the original is 5400? More Heat??, greater current draw?? for example.

I intend to image the original and restore it to the new drive attached to my PC via USB cable.

Do you guys ignore the recovery partition? I am thinking I will and rely on just the C: image for restores.

Comments welcomed.

More heat, noise too probably but I find modern HDDs aren't as noisy as older ones. More power consumption. If you have the money, I'd suggest an SSD.

I got one in my laptop.

Heat wise its about the same, hard drives don't really run that hot anyway (WD ones don't anyway).
As for power consumption, there is very little difference, the main reason it because the power draw is so insignificant compared to other components, a 7200rpm laptop hard drives uses about 2Watts when running, compared to your typical CPU which is 30-60Watts (depending on load) and then the screen which is probably around the same (depending on brightness) so the hard drive represents around 1% of the total power consumption, so going from 5200 rpm to 7200 rpm will reduce your pattery life by about 0.25% to 0.5%.

Oh yeah, as for noise, I actually find the WD 7200rpm drive WAY quieter than the 60GB 5400RPM drive that was in there before it, and performance is a lot better.

Getting a 7200RPM drive is well worth it - these days noise/heat/power consumption are so similar that it's not even worth thinking about.

A recent 7200 RPM drive will most likely be based on newer technology so will probably be quieter, cooler and better than the older drive anyway, even if it does spin faster.

Thanks, guys, good advice.

I mainly use Seagates disk wizard, or paragon Drive copy, both from a bootable CD.

Best upgrade possible for a laptop is indeed a SSD if you dont need the space!

Thanks, WT. Actually, macrium will do all partitions on a drive so may do that. Can't still help wondering about it though. MUCH rather restore to a newish C: image than the Dell original.

SolMiester, this is not my machine and its owner doesn't have much spare cash! A 500GB SSD would SERIOUSLY stretch him!

Who needs or has a 500gb laptop?, use external storage!

My step son has 500Gb in his lappie just put it in as the 250Gb drive he had in it died and that was just about full. Yes he could use ext but at 15 its hard enough to convince him to back it up occasionally

Better to have more storage than not have enough, more to the point a laptop is for portability, I would much rather have a huge hard drive in my laptop than run around with an external drive as well
