An Analysis of Commonly Used Computer Drive Adapters and Computer Storage Cables

A computer has a lot of internal cables that connect different portions of the hardware. There are power cables, data transfer cables, accessibility cables and many more. The same goes for hard drives; there are many types of hard drives, signifying the need for appropriate computer drive connector cables that are suited for these.

Computer Storage Mini-SAS HD SFF-8644 to Mini-SAS SFF-8088 Cable
No matter the make and model of the internal or external hard drive, the appropriate cables for each model used to be made independently by the manufacturer, which had flooded the market with various incompatible computer storage cables. Slowly, standardized storage cables took over, and as more and more manufacturers started using standardized computer drive connectors, the number of incompatible cables too disappeared from the market.

Today, there are mainly 4 types of computer storage cables that are universally used, and computer drive adapters are available for allowing connections between different connectors.

IDE/PATA Cables


This is a multi-use cable that can connect different configurations, with similar connectors. IDE stands for integrated drive electronics, and its main purpose is to connect the hard drive with other components of the computer such as disk drive. They come in 34-pin and 40-pin variants, with the 40-pin variant being more common than 34-pin ones. They can transfer data up to speeds of 33 MB/s to 133 MB/s.

SATA Cables


SATA cables are smaller than IDE cables and usually come with 7 pins. SATA is short for Serial Advanced Technology Attachment and was first introduced as an IDE standard. Because they are much smaller than PATA ribbon cables, they are easier to accommodate, making them perfect for connecting hard drives to motherboards. Adapters are available for connecting SATA devices to non-SATA cables and vice versa.

SCSI Cables

 
SCSI stands for a small computer system interface, and they are bulkier than the other two variants mentioned above. They are commonly used for server storage connections in mainframe and server systems and are not seen in personal computers. They come in 50-pin and 68-pin variants depending on their use and function, and multiple SCSI devices can be connected to a single channel, up to 10-15 devices at maximum. SCSI cables can be incredibly long and twisty, hence they require decent cable management in order to keep the connectors tangle-free and easily accessible in case a repair job is needed. SCSI cables have been around since 1981, and have been used in mainframe computers ever since due to their high data transfer capacity.

What does all Intel NUC SATA cable provide?

Image
The problem for many of us is that desktops traditionally take up a lot of valuable space, and can be difficult to justify in small offices. And who doesn't love a good desktop setup? With the increasing popularity of laptops and tablets, still, these are not able to perform as good as a solid desktop. As a result, it has become challenging for the computers to take up as little room as possible, while maintaining power comparable or even sometimes offering greater functionality than their counterparts. Intel’s NUC is one such system.    What is Intel NUC? Intel has been into NUCs for years, with many variants. The NUC processors aren’t intended to be installed, uninstalled nor swapped out by the end-user. These fully operational NUC systems come with a variety of differences in specifications. There are also NUC kits, again offering different configurations and features. Intel NUC Kits universally come without RAM, storage, SATA cable, or a preinstalled operating

Guide to using RS232 to RS485 Converter

You probably have heard of RS232 which is a serial communication method between computers and devices , but have you heard of the RS485 communication? The great thing about standards is there are so many to choose from. It holds true for electrical interface standards as well. As serial-data standards tend to evolve separately within particular industries, we thus have more standards than we should. Perhaps the most successful serial-data standard for PC and telecom applications is the RS-232. Similarly, the RS-485 and RS-422 are among the most successful standards for industrial applications, however, it is often necessary to communicate between the standards.  What is RS485? ● The RS485 is also known as TIA-485 (-A) or EIA-485 is a serial communication method for computers and devices similar to the RS232. ● Not only is RS485 a single device-to-device interface, but it is also a communication bus that is used to form a simple network of multiple de

Everything You Need to Know About SATA Connection Standards and SATA Power Cables

Introduction Whenever you need to connect a storage device to a computer motherboard, you must have seen a bunch of ribbon or flat like cables being used for the purpose. Different kinds of peripherals and motherboards require a different kind of cables, but all these falls under one major classification: SATA cables. They come up in various types such as AWM 20624 ribbon flex cable, micro SATA cables, Intel NUC SATA cables and so on. But before we dive deep into those SATA cable classifications, we need to have a look at what SATA actually means. SATA Cables: The Industry Standard for Connecting Storage Devices SATA stands for Serial Advanced Technology Attachment and is a standard attachment standard that is widely used for connecting various peripherals such as hard disks, optical drives and solid-state drives to a computer motherboard. What makes them perfect for mass storage devices is the fact that SATA cables and connectors can transmit both data at high speeds
