- 1). *Compatibility*
When replacing a laptop hard drive, the first thing that should be done is to get your computer's specifications. A great place where you can narrow down your search for your hard drive and get your computer's specs is DriveSolutions.com. - 2
The Faster, the Better
*RPM*
Now that you have the information you need, you will probably be flooded with a lot of different choices. Depending on your budget, you may just want to go for the drive with the most space. Just because a hard drive has 250GB of space doesn't mean it will be a good one. You will need to look at the drives run speed, anything under 5400RPM should just be ignored. The higher the speed, the better it will run. - 3). *CACHE*
Determine the size of the drive's cache, again bigger is better. You really shouldn't consider anything under 8MB. - 4). *Caddie*
Determine whether you have to buy a caddie (the device that holds the hard drive), or if you can re-use your old one. If your old one is damaged then you may need to inspect the rest of the computer to make sure that there is no damage there. They are very delicate instruments. - 5
*Bargain Shop*
Once you have determined exactly what you want in a hard drive, start to bargain shop. Just because you did all of your research on one site doesn't mean you have to buy from them. Pricegrabber.com will compare many different prices for you and Newegg.com is a great place to look to replace a hard drive as well.
