What is the most important factors to look at when buying hard drive?

I am looking to purchase a new hard drive for notebook upgrade and was wondering what I should be looking at? Like are io operations all that important?

thanks

Varies.

Random write/read speed for day to day performance and sequental write/read if you deal with a lot of space. SSD's pretty much win in this category.

Size is another factor if you're going to be storing lots of files on it

I'm sure someone else else will chime in with other things too.

1.) Warranty/Reliability - I've only had one hard drive fail, but they seem to be getting slightly less reliable. I stick to brands I know and don't cut corners for a good deal.

2.) Performance - seek times, read/write, etc.

3.) Noise issues or vibrations, heat issues (laptop drives only)

RRP can be factor effecting performance. Standard is 5200 rrp and 7200 rrp is performance standard.
