The main difference between the IDE and SATA storage connectors is that SATA has a much faster data transfer rate, compared to IDE. SATA connectors usually support transfer rates of up to 6 gigabytes per second compared to only 133 megabytes per second for the IDE.
IDE stands for integrated drive electronics and it has a ribbon like cable with either a 40-pin or 80-pin connector. It was created, in 1986 and was the standard cable connector for mass storage devices until SATA was introduced, in 2003.
SATA, which stands for standard advanced technology attachment, has a narrower cable with a split data and power connections. It has a 7-pin cable and unlike the IDE that has one or more 40- or 80-pin connectors in once cable, SATA has only one connector per cable. The SATA was designed to simplify cabling and overcome the limitations of IDE connectors.
The IDE data transfer interface runs in parallel. This means that in order for a transferred data to be processed, it must be completely streamed into the receiving end. SATA serial connections, on the other hand, transfer the data using a single connection, which significantly cuts the delay in streaming. This is the reason why SATA cables transfer data much faster. Almost all recent computer motherboards and computer hard drives are manufactured with SATA connections.Learn More
Serial advanced technology attachments (SATA) work by transmitting data between a motherboard and hard drives through a seven-pin cable that sends information twice as fast as previous technology, according to About.com. A single high-speed serial wire now inhabits most computer systems instead of a parallel bus system that incorporated 40-pin wires or 80-pin wires.Full Answer >
Storage devices are any type of hardware that is capable of storing and retrieving data. Most often these devices come in the form of hard drives or optical discs.Full Answer >
Optical storage devices are any storage methods that use a laser to store and retrieve data from optical media. Optical storage media includes CD-ROM, DVD-ROM, DVD-RAM, WORM cartridges, erasable optical cartridges and removable mass storage media, which includes flash drives and removable disk, or RDX.Full Answer >
Primary memory is the internal working memory of a computer, and it includes RAM and the cache. Secondary storage is also called external memory, and it includes the computer’s hard drive.Full Answer >
