One necessary and extremely important component of computers is the hard drive.  The hard drive stores your games, applications, music, pictures, videos, and documents.  As such, you should be sure the notebook PC you’re thinking of buying has a hard drive that can give you the storage and performance that you need.

There are two important considerations when looking at hard drive specifications for your PC notebook

: hard drive size and hard drive revolutions per minute.

Hard Drive Size

Hard drive size simply refers to the data storage capacity of a hard disk drive.  Desktop PC hard drives offer sizes of up to 500 gigabytes (GB), while notebook PC hard dives offer sizes of up to 160 GB.  Notebook PC hard drives are more expensive than desktop PC hard drives with more than twice the capacity of the notebook hard drive.  This is due to the engineering difficulties inherent in making high-capacity hard drives for the smaller notebook computers form-factor.

A notebook PC’s hard drive size indicates how much data a notebook PC can store.  If you are interested in storing large amounts of movies, pictures, or music, you want to go with a larger hard drive to avoid running out of space.

A hard drive’s size has very little to do with its performance, unless the drive is almost Software.  The Windows NTFS File System requires a minimum of 10% of the hard drive to be free space for optimum performance, and it frequently requests as much as 15%.  This means that, on a 40 GB drive, Windows prefers that you use a maximum of 34-36 GB, leaving 4-6 GB of space unused.  On a 160 GB drive, Windows prefers that you use a maximum of 136-144 GB, leaving a massive 16-24 GB unused.  If you start to go over these Windows storage limits, you may notice your PC’s performance taking drastic hits.

Hard Drive revolutions per minute

Hard drive revolutions per minute is a hard drive’s rotational speed, measured in revolutions per minute (RPM).  Desktop hard drives now have speeds as high as 15,000 revolutions per minute.  Notebook hard drives, on the other hand, currently have an revolutions per minute ceiling of 7200 revolutions per minute.

A hard drive’s revolutions per minute indicates how oem the drive’s spindle will move or how oem the hard drive platters will spin.  The higher the spin rate is, the shorter the seek time and latency will be.  This translates to quicker data access and transfer.  

How Large and How oem

The greater the free space and the higher the revolutions per minute, the better your notebook PC’s performance will be, so go for a slightly-more-than-comfortable size and the highest revolutions per minute for your notebook PC’s hard drive.  A large hard drive gives you the option to expand in the future, and you can never go wrong with a notebook PC that can give you oem access to your stored data.

It is even more crucial that you go with the top-of-the-line hard drive size and revolutions per minute for your notebook PC if you are fond of PC games, you have a lot of multimedia files, or you want to be able to easily upgrade your programs.  These games, content and programs take up a lot of space.  A high revolutions per minute hard drive can also cut down on game load times, giving you more time enjoying your games and less time staring at loading screens.
