Buying Tips For a Harddrive

Hard drives and more....

If you own a PC then you (or someone) will have to change the hard drive at some point. Hard drives will fail!  Always keep a backup of your very important data because the day will come when you computer will just not boot up anymore or when you try to access the information it will be corrupt. 

Besides the failure of a hard drive, other reasons to buy a new one might be that your current hard drive is full and you need more space for those huge programs that are being developed.  You could just add a hard drive to your system and continue to use the current drive for just windows.  This is the more simple approach because you don't have to back anything up or reload any software.  But be warned if it is not a SCSI drive it will slow your computer down.  The system has to check both hard drives for information that it needs and since IDE drives need the CPU's attention while it does this then your graphics or something else may not proceed as smooth as before.  The amount it slows your PC down is CPU dependent.

The current SCSI drives are about twice the price of IDE drives that have the same capacity. In multiple drive systems SCSI is the way to go.

When buying a new HDD, many people only take in consideration its size. But HDDs may also differ in terms of speed. Since the HDD is one of the major bottlenecks as far as the computer's overall performance is concerned, it's extremely important to have a fast HDD if you want to have a fast computer. Even if the size of your current HDD fits your needs, a HDD upgrade can give you a good performance boost. When searching for a new HDD, try to look for it's access time (usually measured in ms). It's like a summary of the HDD's performance. The faster the HDD is, the smaller its access time.Also, make sure to check out how much cache it has, and how many rotations per minute it performs (RPM). In both cases, the bigger, the better. If you have some extra money to spend, SCSI HDDs are much faster than the regular IDE ones, but they're usually much more expensive as well, and require a SCSI controller card, which you have to purchase separatedly. They're definetly not the best bang for the buck, but if you're looking for top performance, then they can't be beaten.
