Part Information - Hard Drive

Along with the many types of different parts, there are many types of hard drives. These hard drives come in different speeds and capacities. The prices fluctuate accordingly with each of the types of drives. You can get different types of hard drives too, internal and external. External hard drives are usually really large, like in present days they would consist of multiple terabytes, which in case you didn’t know, 1 terabyte equals 1000 gigabytes. The external hard drives usually hold a database or something for companies. Some people use them to hold their media collection, such as movies and music. An internal hard drive is usually half a terabyte, or 500 gigabytes, in present time. Before they were as little as 50 gigabytes, and even 10 gigabytes. Along with the amount of space present in the internal hard drive, you need to pay attention to the RPM. The RPM, stands for rotations per minute, determines the access time on the hard drive of the computer. Common RPM’s are 5400 RPM and 7200 RPM. Basically, the higher the RPM, the better the hard drive it is. You can find decent deals on www.newegg.com for 500 GB to 1 TB hard drives with 7200 RPM for around $60. That’s a really good deal now a days. Also, you will note that there are Cache’s marked with the hard drives. The cache pretty much lets the computer multi task better. It can do things faster with a bigger cache, so you want to aim for a larger cache when looking at hard drives. Along with the capacity and speed, you have to make sure that the connection cord matches your motherboard. The most common connection type in present day is the SATA 3.0Gb/s connection. There are other connections available such as the SATA 1.5 Gb/s and the IDE connections.
