SCSI is a much less popular interface, and so production costs are higher (due to lower demand)
It is also physically more expensive for the materials to produce them, as SCSI is a much larger interface with more, larger, and higher quality cable. In the case of SAS (Serially Attached SCSI) and fiberlink SCSI, these are also expensive to produce.
IDE is the standard for desktop systems, and as such a lot more time and money has gone into making them cheaper and more available. Plus, IDE has now been discontinued in favor of SATA, making most IDE items go into clearance.

SCSI, pronounced as scuzzy, stands for Small Computer System Interface. An SCSI port is used to attach peripheral devices that use the SCSI system , mainly for data transfer.
SCSI stands for Small Computer System Interface. It is a set of standards for connection and transfer of data to peripheral devices.
SCSI interface would be what you're looking for.
SCSI (Small Computer System Interface) is a set of standards for physically connecting and transferring data between computers and peripheral devices. SCSI is most commonly used for hard disks and tape drives, but it can also be used to connect other devices, including scanners and CD drives. An SCSI drive is usually referred to a disk drive that uses the SCSI standard interface and commands to connect and transfer data to/from the computer.
A SCSI controller (pronounced 'Skuzee') - is used to enable a computer to 'talk' to peripheral devices - such as printers, flash drives, hard-disks etc.
It connects eternal device, connects power supply to analyze data.-Small computer system interface.-for peripheral devices connectivity (8 devices (0-7))-Internal and external buses like power supply and extensive peripherals.-Ultra SCSI - 32 devices (no wire is required, all with is uses is wireless).-Physical drive accession - (Single hard dish is physical drive).-Logical drive accession.-SCSI ID is available in the device.Configuration done in booting.-5MB/Sec.-SCSI: 2--Fast SCSI - 10MB/Sec.--Wide SCSI - 16bit 20MB/Sec.-SCSI: 3--Support 32 device - 40MB/Sec.Note: the above answer is in the form of points.
SCSI, Fast SCSI, Ultra SCSI, Ultra2 SCSI: 8 devices Wide SCSI, Fast Wide SCSI, Ultra Wide SCSI, Wide Ultra2 SCSI, Ultra3 SCSI, Ultra160 and 160+ and Ultra320 : 16 devices Of course, the number of devices supported depends not only on protocol limitations, but cable length, number of cables used, etc.
Ultra wide SCSI. wide SCSI buses support 16 devices, rather than the eight devices specified in regular SCSI.
