Difference between IDE and SATA
  • Last Updated : 20 Oct, 2020

1. Integrated Drive Electronics (IDE) :
IDE is an interface standard introduced in the year 1986. It is for connection of storages devices such as Hard Disk Drives (HDD), Solid State Drives (SSD) and CD/DVD drives to the computer. In IDE data transfer speed ranges from 100 MB/s to 133 MB/s. It is a parallel connector. It gives a slower performance and does not support of hot plugging. It is an older concept.

2. Serial Advanced Technology Attachment (SATA) :
SATA is a computer bus interface or standard hardware interface introduced in the year 2003. It connects hard drives, Solid State Drives (SSD) and CD/DVD drives to the computer. In SATA data transfer speed ranges from 150 MB/s for SATA I and 300 MB/s for SATA II. It is a serial connector. It gives a faster performance with support of hot plugging. It is a newer concept. SATA cables are better than IDE.
