![]() ![]() SCSI interface is an upgrade over SATA and PATA interfaces for many reasons such as round-the-clock operations, speed, storage, and several others.įor connection, SCSI hard drives use a small computer system interface – which is a standard for connecting peripheral devices such as printers, scanners, and others.īest of all, they allow the connection of peripheral devices such as printers, scanners, and other hard drives. In addition, they have thinner cables and a cable limit of 1 meter. This means that they transfer data one bit at a time.Ī notable advantage SATA interfaces have over PATA interfaces is the transmission of data at a rate of 150 – 300 MB/S. The mode of connection to a computer remains the same as PATA, but instead of parallel signaling technology for data transmission, they use serial signaling technology. In recent times, a lot of desktop and laptop computers have gotten SATA interfaces because they have superseded PATA interfaces in size, power consumption, and even better pricing. Serial Advanced Technology Attachment (SATA) PATA interfaces are made of mechanical moving parts and are based on parallel signaling technology – meaning they transmit multiple bits of data simultaneously. Apart from PATA, they are also called Integrated Drive Electronics (IDE) and Enhanced Integrated Drive Electronics (EIDE). They were named Parallel Advanced Technology Attachment because they use a parallel ATA interface to connect to the computer. They can have up to 80GB capacity and transfer data as fast as 133 MB/S. The PATA interfaces were first introduced to the market by Compaq and Western Digital in 1986. Parallel Advanced Technology Attachment (PATA) In this article, I’m now going to elaborate on each of these interfaces and types of hard drives as concisely as possible. So, there are PATA hard drives, SATA hard drives, SCSI hard drives, and NVMe drives. These names come from the way they connect to the computer. Serial Advanced Technology Attachment (SATA).Parallel Advanced Technology Attachment (PATA).In this article, I will cover the different types of hard drives so you can choose the best for your computer.īut firstly, let's look at interfaces – the connecting part between the computer and the hard drive. Since the first release of hard drives by IBM in 1956, hard drives have evolved from being the size of a refrigerator and having a storage capacity of just 5MB to ones that are pocket-sized and have up to 4 TB of storage capacity. Due to this, they help computers store files and other data for a long time – as long as they don’t get damaged or corrupted. The non-volatile nature of hard drives means they don’t lose data, even if power is lost. ![]() It holds program files, documents, pictures, videos, music, and more. ![]() A hard drive is a non-volatile hardware component on a computer that acts as the storage for all digital content. ![]()
