Data storage technology has been among the very important fields of tech development in the last few decades. In only a few years, we’ve been able to lower the size of 1TB of storage data from large, standalone drives which had to be powered independently to small microSD cards.
It is easy for people to look out for a refurbished hard drive to save money. These days, there are an increasing number of storage options available to the ordinary consumer which are cheaper, more portable, and more reliable.

MicroSD Cards
Although microSD cards and thumb drives are all the rage now, our laptops and computers still rely heavily on the tried and test hard drives. There is nothing old-fashioned about today’s hard drives, however, as there are now different types that you can choose from. What are the different types of hard drives and one should you choose?
Small Computer System Interface It utilized a 50-pin flat ribbon connector to connect hard drives and other peripheral devices to computers. More popularly known as”scuzzy,” the SCSI standard was adopted by the majority of the tech and hardware leaders of the time.
With normal interfacing technologies, SCSI permitted between 7 to 15 devices to be attached to one motherboard. This assisted computers at the time embrace a simpler, less cluttered, and cheaper form element. Earlier versions of SCSI connections utilized only parallel interfaces, but after iterations allowed serial relations which offered faster data transmission.
Although SCSI is considered mostly obsolete, SCSI interfaces can nevertheless be found in certain low-end computers. Nowadays, working with SCSI devices could be particularly troublesome considering that about a dozen types of SCSI connections are developed over time. Discovering the right cable to the interface of the device you’re using can be quite a headache. Produced by Western Digital in 1986, the introduction of PATA drives supplied a driveway with a common interface that can be used across the different devices commonly used at that time.
PATA Drive
The first versions of the PATA drive utilized a 40-wire cable which terminated in a wide 40-pin connector. Later models had 80 wires, which effectively improved data transmission rates. If you’ve worked with computers for a long time, then you’re likely familiar with the different appearance of the ribbon cables that are used to join PATA or IDE drives.
PATA drives are capable of data transmission speeds of around 133 MB/s. 2 PATA drives can be connected using a single cable in master/slave configuration. Because most motherboards may have two channels for IDE connections, up to four PATA drives may be connected to one motherboard.
Data is kept in a PATA drive onto a rotating disk with magnetism. After the drive is engaged, a read-write head goes very close to the surface of the disk while the disk rotates. Changes at the magnetization of this substance are detected by the read-write mind and converted into information. Conversely, the read-write head may also make changes to the magnetic properties of the disc to store additional data. Though magnetic storage technology has evolved through the years, this exact same basic principle remains greatly used until today.
Here is what about PATA drives: they are obsolete, but you may still find them in any of the refurbished hard drive marketplace. If you walk into any computer store nowadays, it will probably be very unlikely that you find any PATA drives. The most important reason behind the obsolescence was the development of its successor — that the SATA drive.
