IDE Vs SCSI

In the past SCSI disks are the ones we used side in the enclosure and can configure them as RAIDs.
Nowdays, I have seen the word SCSI used for regular disks similar to IDE or maybe even they  are IDEs disks.

what is really the difference

SCSI disks are really used in server hardware or workstation hardware that needs fast access times for data on an hard drive. SCSI is very different from IDE. Now there is newer technology like SAS which is Serial Attached SCSI.

SCSI and IDE really have nothing in common. Different drivers, different bus, different speeds.

IDE is consumer, and old consumer at that. Parrellel is what is generally called IDE, or PATA. SATA replaced EIDE /  IDE a few years back now.

SCSI has been a mostly enterprise solution for many years now, offering 15k RPM drives and great support in hardware RAID.

SCSI is type of cards "SCSI CARD" this card has connections from the hard disks ... so SCSI card is the media between the HDDs and the motherboard

the IDE it is chip on the Motherboard it can take direct connection from the HDD and the connection & cable type called IDE

sure u know that u can control the SCSI Disks with setup RAID ... still with IDE u can can setup RAID by windows server by changing the disks to dynamic disk then setup the RAID

All the best
