I saw a port on my laptop which was an eSata port. I was wondering what it was and then I found out that there are different connections for the hard drive. What are the sata and ata hard drives difference?
You got it right. Both SATA and ATA are connection interfaces for hard drives. Right off the bat, ATA is older than SATA and therefore slower and technologically backward. Let’s get into the particulars.
ATA stands for Advanced Technology Attachment. It is basically an 80 pin connector. As of now, both ATA and SATA are out of date. SATA is a technological advancement over ATA. SATA offers faster data transfer speeds and higher data rates in addition to being physically smaller. SATA replaced ATA and then eSATA became the successor of SATA. The world has now moved on to NVME and M.2.
