Solved HDD spindle speeds ...?

Hi...I want to replace a hard drive in a netbook...Asus X101CH.

Does it matter what the spindle speed of the HDD is ? ie,5400 or 7600 ?

I am just wondering really as I intend to use the same or as near to the old one as I can but I have not taken the hard drive out yet.

Thanks...

It will pretty obviously effect both the read and write speed; if you've past sixth grade math you'll know that a spinning disk around a center point will create torque, the further away from the center you are the faster you'll move compared to the static ground, same here, there's a static "Head" (Thing that reads the magnetic values off the disk) and a spinning platter (Think of it like a CD), the edge (start of the disk) will be the fastest while the center (end of the disk) will be the slowest.

If a disk spins at 1 spin per second, you'll only be able to read the data that passes over the head once per second, while if it spins 10,000 times a second, you'll be able to read the data that passes over the head 10,000 times per second.

Personally, for a netbook, 5,400RPM is enough.

With a netbook/notebook, one of the things to bear in mind is that you will be quite likely running it on battery power - after all they are designed to be portable, and that is a likely scenario. Consequently, we need to look at saving as much power as possible. Since a faster disk RPM equates to more power drain, most modern netbooks use 5400 units. Some of the earlier units used 4200 drives.

Consequently, I would stick with a 5400 RPM drive. Alternatively, have you considered an SSD ? Drives of 256GB+ are available, although this option will come at a cost premium.

Thanks for the answer...I have to say that I thought it clear enough that what I was asking is...does it make any difference to the netbook itself...like with compatibility issues maybe...I do not know for example,if there are any limiting factors inside the workings that would mean a specific speed is the better of the two...and I still would like the original question to be answered.

re-phrased question...does it matter what spindle speed of hard drive I replace my faulty hard drive with ? ie,is there any need to consider the original or can I just replace with any speed of hard drive ?

Thanks.

Thanks for the answer "Dwarf"...I will mark as solved.

You're welcome.

If you do decide to go with an SSD, you should find that your battery life will improve considerably as there will no longer be a drive motor to keep spinning.

Frankly, Acer's aren't worth enough to justify the cost of an SSD.
