why SCSI HDD is more expensive than IDE HDD? The capacity and spinning speed are the same, but price varies.
SCSI (Small Computer System Interface) and IDE (Integrated Drive Electronics) are two different types of hard drives. SCSI drives are typically used in servers and high-performance computers, while IDE drives are commonly found in personal computers. The main difference between the two is their interface - SCSI drives use a parallel interface, while IDE drives use a serial interface.
There are a few reasons why SCSI HDDs tend to cost more than IDE HDDs. One reason is that SCSI drives are designed for high-performance and reliability, making them more expensive to manufacture. Additionally, SCSI drives often have more advanced features such as hot-swapping and error correction, which contribute to their higher cost.
It depends on the specific needs and usage of the user. SCSI drives are generally better for high-performance and server applications, as they have faster data transfer rates and better error handling. However, for basic personal computer usage, IDE drives are a more cost-effective option.
Yes, it is possible to use both SCSI and IDE drives in the same computer. However, they cannot be connected to the same interface and require separate controllers. This means that special hardware and configurations may be needed to use both types of drives in one system.
Aside from their higher performance and reliability, SCSI drives also have a greater capacity for expansion. IDE drives typically have a limit of two drives per controller, while SCSI drives can support up to 16 drives per controller. This makes SCSI drives a better choice for large storage systems or servers that require multiple hard drives.
