IDE is the oldest technology, designed for desktop applications only.

And not to mention, it is the cheapest of them all.

SATA is designed to replace IDE. It is best for desktop application.

It also has good performance in server but not as good as SCSI when it comes to heavy usage. That is because SATA driver only has a single processor for executing commands and other tasks.

SCSI is designed for server. It is very expensive. The driver has dual processor and is specially built to perform well for heavy database usage, multi-user systems, and even in gaming.

USB is for external hard drive use only.

From your question, if it is for desktop use, SATA is better than IDE. If it is for server use, SCSI is best.

 If for external hard drive, USB is not the best to use. You can choose among SCSI, Fire Wire, or e-SATA.

The most suitable connecting method for a computer really depends on the user because most of the motherboards today support both SATA and IDE. I’m not sure if IDE will become obsolete since CD/DVD drives rely on this method. SATA drives are thinner than IDEs which on the other hand, are bulky. But when it comes to speed, I think they are just the same.

SATA stands for Serial Advanced Technology Attachment or simply Serial ATA. This is now the new standard for connecting or attaching the hard drive to the computer and the successor to the old and original IDE. The Serial ATA is based on the serial signaling technology while in IDE, it uses parallel signaling. SATA is for SATA drives and PATA for IDE drives or Parallel ATA. SATA has quite a few practical advantages over PATA which has been used since the 1980s on hard drives.

The SATA cables used on SATA hard drives are thinner, flexible, and less massive compared to the ribbon cables required for connecting regular PATA hard drives. It is also a lot longer than PATA ribbon cables which allow the designer added space in the physical layout of a system.

IDE stands for Integrated Drive Electronics. It is the standard electronic interface between a computer’s storage devices and its motherboard. The IDE is based on the IBM PC Industry Standard Architecture [ISA] 16-bit bus standard. Other computers that use different bus standards also use this.

SCSI stands for Small Computer System Interface. This is a group of ANSI standard electronic interfaces which permit personal computers to communicate faster and more flexibly with peripheral hardware devices like CD-ROM drives, tape drives, scanners, disk drives, and printers than previous interfaces. It was created at Apple Computer and still being used in the Macintosh. The current set of SCSIs are parallel interfaces. SCSI ports are still being built on many computers today and are supported by major operating systems.

USB stands for Universal Serial Bus. It is the industry standard that identifies the connectors, cables, and communications protocols used in a bus for communication, connection, and power supply between electronic devices and computers. It was created in the mid-1990s.
