What is the difference between sata&pata hard drives?
From a user’s point of view, there isn’t much difference between a SATA (Serial ATA) and a PATA (Parallel ATA) hard drive. They both store data on a series of magnetically charged metal platters. The real differences are internal.A Short History of ATAThe ATA in SATA and PATA stands for “Advanced Technology Attachment.” ATA is a standard with a long history, with many revisions over the years. It was originally created as a standard for attaching hard drives to IBM’s “AT” series of computers.Serial vs. ParallelA parallel data connection uses multiple data lines to transmit multiple signals at once. Serial connections use a single data line, along with some control leads and a ground lead. Parallel connections were used to compensate for the relatively low (by modern standards) speeds at which a single lead could transmit data.PATAParallel ATA is actually a “retronym,” an acronym created long after the fact, mainly to differentiate from the newer SATA standard.
