Hard Drive Interface Type

Generally speaking, computer hard drive mainly has IDE and SATA two kinds of interface types. The following part will show you these two types of interfaces in detail. 

SATA(Serial ATA): It is abbreviated from Serial AT Attachment. Today’s new computers mostly use a SATA hard drive interface, but on some older computers, you can still see the IDE interface. SATA hard drive interface adopts serial connection mode and SATA bus uses embedded clock signal, with stronger error correction ability. 

The biggest difference from the past is that SATA can check the transmission instructions (not just the data) and automatically correct errors if found. This greatly improves the reliability of data transfer. The SATA interface also has the advantages of simple structure and hot plug support.

IDE(ATA): The IDE interface is also known as the ATA (Advanced Technology Attachment) interface. Most hard drives used by PCs today are IDE compatible. Old computers use an IDE hard drive interface, but this interface due to slow transmission speed, has been obsolete.
