As we all know, SCSI interface hard disk in many ways is much stronger than the IDE interface hard disk. However, good goods are not cheap, and the price of hard disk of SCSI interface is much higher than that of ordinary IDE interface. In order to find a balance between price and performance, IDE RAID cards have emerged. But its performance improvement is limited, and its architecture is still only in the scope of the IDE. In order to better compensate for the lack of IDE interface, in order to make SCSI more popular, IDE-to-SCSI card was born.
Is it SCSI or IDE?
This is not a problem for home computer users to consider. This is not a matter of DIY's taste when it is down. SCSI is the standard interface used by workstations and server hard drives. Although both IDE and SCSI are parallel interface technologies, SCSI can support more bandwidth, more connected devices and longer transmission distance (maximum effective transmission distance of ordinary SCSI can reach 12 meters). In addition, SCSI can also support multitasking operations. Each IDE cable can only support two devices, and each SCSI cable can connect 15 devices. SCSI interface data transmission rate in the range of 20MB/s to 320MB/s. Can cope with data transfer tasks in a variety of environments.
