5400 vs 7200 rpm hard drive

by aliciacw / October 7, 2009 6:39 PM PDT

The Hitachi hard drive in my Dell Inspiron 1420 laptop is dead. It would often get what I believe was very hot, like 40C. Should I replace it with a 7200 RPM drive or would a 5400 RPM drive suffice? Would adding RAM compensate in anyway for a slower RPM hard drive? I don't play games or edit music or video, only high-resolution photos.

40C is not hot.

The spec I read was more like 55C at the top end.

Ok. I love 7200 RPM drives but if I want less heat and more battery time I go with the 5400 drives every time.

It spiked much higher, but I'm glad to hear that

In reply to: 40C is not hot.

I was thinking I baked my hard drive - maybe something else caused the problem. Could high RPM in itself harm the drive if it's in constant use?

Basically, I was told by someone who is very into computers that I would notice the difference. Better battery life and reduced heat are appealing, but I know I'm already impatient with loading Vista.

I'd like to note that because of your advice on this forum, I've made back-ups of my back-ups and only face losing six weeks of data. I'm going to fight to get it out of that drive, but I'm grateful it's not worse.

Well we now have 10K RPM and even 15K RPM drives.

About harm. More like WEAR. These are mechanical things with a 5 year design life (most models.) And if you get some user that runs defraggers daily you could eat into the life span. Heat doesn't help but your number was under the spec by quite a bit.

Now there are some that will be suckered into buying solid state (flash) drives but those have a life span lime as well.

The lesson is all about backup since there is no storage today that goes for decades in the hard drive category.
