Why upgrade your hard drive?

Simple explanation is that today it is the bottleneck of most computer systems. It is the slowest link.

While other components such as RAM and CPU work in hundreds, even thousands of megabytes per second, when it comes to hard drives transfer rates begin as low as single digit numbers for a random access.

Reasons to upgrade the hard drive:

• to expand storage space
• improve computer performance
• as a proactive action to prevent possible failure because of constant wear and tear
• as a neccessary action when the drive fails

One of the most common upgrade is when there is a need for an additional storage space for music, videos and other large media files. In order to upgrade first requirement is to determine which type of drive a particular computer can see. Examples are IDE, SATA, SCSI. Afterwords that drive would be physically added as long as there are enough bays within the computer system. There could be an additional configuration in BIOS before that drive become visible to an operating system such as Microsoft Windows or Mac OS X.

There are people who will try to get every tiny bit of performance out of their system. Everything from overclocking to upgrading a Solid State Drive. An average users will want the balance of performance, size and price. In that case there are a few things to look for in a regular IDE or SATA drive, which is the cache size and RPM, the higher the better anything that's above 7,200 RPM would be OK. There is one other important variable which is the latency to access files either randomly or sequentially. Normally any hard drive that spins will have latency measured in milliseconds, those who seek the ultimate performance will go for the latest technology which is SSD (Solid State Disks) that find and access file in nanoseconds, virtually in real time without any delay.
