Replace the hard drive on his laptop: interest?

There are few, we have tried to determine if it was worth to replace the hard disk on a desktop computer, specifically in a passage from Windows XP or Vista to Windows 7, an update which believe many of you at this time. We noted a slight decrease in consumption and a small increase in performance, which did us say that if you intend to make major changes to your system, it could worth thinking to change disk hard if you had the budget, the new models are actually slightly higher than the old.But is it the same for a laptop? Is it possible to achieve a significant improvement in performance or autonomy by replacing the hard drive?

While the largest hard drives for desktop today reached a capacity of 2 TB, it must be said that progress was clearly less dramatic on laptops: as a general rule, the 2.5-inch hard drives are slower and smaller size (640 GB maximum) than their counterparts to desktop. This that does not mean that there was no evolution in this sector: indeed, the strong growth in sales of laptops in recent years, needs are well there, both in terms of reduction in consumption to increase capacity. It was therefore normal that the market follow.There are two broad categories of hard drives format 2.5 inches: general public and high performance. The first were generally larger but reduced to 5400 RPM rotational speed while the latter are more Rapids (7200 RPM) but also more small capacity: for example, it is now public models 640 GB (and 9.5 mm thick) and drives high-performance 500 GB.

For this article, we have taken as a basis a Dell Latitude D630, a laptop equipped with a disk hard Hitachi Travelstar 7 K 200 160 GB (which was one of the first 7200 RPM SATA models), and we have replaced this latter by a Travelstar 7 K 500, the last born of Japanese and most recent of two generations manufacturer plants. What is the impact of this change on the performance of our Core 2-based notebook? The new hard disk is sufficiently effective to affect its independence? This is what we will attempt to discover.
