We recently looked at the impact of a hard drive upgrade on a desktop PC to find out whether or not it's worth replacing a three-year-old disk with a brand new one. Our scenario involved the now-common choice of upgrading from Windows XP or Vista to Windows 7, and starting over with new storage at the same time. We found small benefits on the power consumption side and more noticeable increases on the performance side.
In short, if you intend to make major modifications to your system, then it makes a lot of sense to question your hard drive. Capacity, performance, and power consumption have reached new levels. But what are the results on a mobile machine, where many of those factors end up being multiplied? Can you get noticeably more performance or increase the battery life if you exchange the hard drive?
Desktop drives have marched straight up to 2TB capacities, but progress has been even more extensive on the mobile side. While 2.5” hard drives remain much slower than desktop hard drives, capacities have reached 640GB, and the drives have been more finely tuned for power consumption and efficiency. Additionally, growth in the mobile space has been more substantial than in the desktop segment.
Mobile HDDs typically fall into two markets: mainstream and high-performance. Mainstream drives often provide the highest capacities at a 5,400 RPM spindle speed while performance models rotate at a faster 7,200 RPM speed, albeit at smaller capacity points. Mainstream hard drives are available at up to 640GB capacity (9.5mm z-height) while the high-performance segment has reached 500GB.
We took a Dell Latitude D630 laptop running a 160B Hitachi Travelstar 7K200. This was one of the first mobile 7,200 RPM SATA hard drives. Hitachi recently released its Travelstar 7K500, which is two generations newer than the 7K200. What’s the 7K500's impact on performance for our Core 2 notebook? Will the new drive be efficient enough to increase battery life? Let’s check it out.

stick an SSD in there, whadda you NUTS?!
less weight, less noise, less heat, less power draw (uh-huh!), 10 times the shock resistance, double the read bandwidth of normal HD's..
cheers!

You forgot 10 times the price. I hope they manage to perfect racetrack memory soon, if you'll excuse the cliche that would give us the best of both worlds.
certainly numbers speak for the new drive but i wonder if the recorded performance improvements could be (at least in part) due to better organization of files (not fragmented and possible some redundant junk not included). i would not mind to see same setup restored back onto original hdd (maybe after format).
What about us guys out there with old 2.5" IDE laptop drives? Is it worth splashing out on a new drive and more RAM for Windows 7? We can,t all afford SSD,s. It would be pointless anyway with an IDE interface, right?
I'd be a lot more interested to see an article about benefits of stepping up from 5400rpm to 7200 rather than this. Seriously, who in their right mind would want to spend money on a similar (read "same") drive for such little gains? On the flip side, I'm sure there are many people with 320 and 500GB 5400rpm drives who would like to know exactly what the benefits are and whether it worth the money or not...
