How to chose hard drive for PC and laptop

Published

on

Dealing with computers, advanced users often faced with the need to change the hard drive or to acquire external one. But how to find the proper type for your needs and computer facilities?

1a

HDD (Hard disk drive) – performs the function of storing all your information on your computer. It is better to take into account the volume you need. Although there is also a double edged sword, because if the volume is too large, it will detriment of speed.

So, not much delving into the history of hard drives remember that today there are two main connector interfaces of hard drives connection (varieties differ in data rate).

2

1) IDE (Integrated Drive Electronics)

This is an older type of connection of hard drives, they are also called ATA – devices. Characterized by a lower data rate on its advanced brother (SATA).

2) SATA (Serial ATA)

This interface is most common today. There are varieties of SATA by bandwidth. After defining the connection type (ATA or SATA) you can move on to the next step, to define the optimal volume and HDD speed.

When selecting HDD is important to take into account parameters such as the spindle speed and the amount of cache memory.

3

Rotation speed (RPM) determines the rate of data reading from the disk. It is also necessary to pay attention to the amount of HDD cache memory – the more the amount of cache memory, the faster the speed of processing of small files. The most important for those who often work with a large number of small files sizes. To date, the most relevant in terms of price / performance is the volume of 1-1.5 TB hard drives.

Manufacturer

Many argue which manufacturer is better, but in fact, today there are only two of them – a Seagate and WD. Someone prefers the first and someone, on the contrary, the second manufacturer. But more important are the characteristics of the hard drive.

In addition to standard HDD, there are SSD.

SSD drives consist of a controller and memory chips and contain no moving parts. It is, by the way, one of the most important advantages of SSD over HDD. Exist two types of SSD drives – SSD drive using flash memory and RAM memory. Speaking in a nutshell the SSD drives using RAM memory are the fastest and most expensive storage devices in the world.

The advantages of SSD:

  • No moving mechanical parts, SSD is not “crumble” as the HDD.
  • SSD are more compact and are generally in accordance with the form factor of 2.5. While desktop HDD is 3.5.
  • No noise – any HDD at high load on begins to show signs of life in the form of noise and crackle.
  • SSD are more resistant to mechanical stress and have a wide operating temperature range, including very high, in which the HDD just can not get to work.

Disadvantages

Dubbing

This is the biggest drawback of SSD. SSD drives have a limited number of write and rewrite, no more than 100000 times.

Most of SSD users are familiar with this shortcoming, so they use a hybrid  bunch of SSD + HDD. The HDD is mainly used to overwrite, while SSD is used to speed up boot and run Windows and all programs installed on the drive.

5

Price

The price of SSD drives is much higher than conventional HDD. When this value to SSD itself formed depending on the number of gigabytes. Every year the price of the 1 GB SSD drive falls, and with it, the price falls significantly to the HDD.

Agency Seeks Collaboration For IoT Unlock

Published

on

The National Information Technology Development Agency (NITDA) has emphasised the need for collaboration to unlock Nigeria’s potential in Internet of Things (IoT) and its revolutionary impact on the countrys digital ecosystem.
Director General of NITDA, Kashifu Inuwa, who disclosed this is in a bid to implement the Digital Transformation pillar of Strategic Road Map and Action Plan (SRAP 2021-2024) of the agency.
Inuwa made this plea while delivering his keynote address at the IoT West Africa Conference and Exhibition 2023 in Lagos State, recently.
The DG noted some challenges that need unlocking in order to access the potentials of IoT, especially infrastructure, cyber security, and data protection, stating  that most IoT use cloud-based solutions  Alexa, Google, and others.
According to him, todays computer systems are outperforming humans in many endeavours, especially the rise of generative Artificial Intelligence (AI), chat GPT, etc.
He said that is the fabric of the shift humanity is witnessing in accelerating the convergence between physical, biological, and digital world.
“Looking at the areas you can apply them, such s in agriculture, we need to increase our agri-products, and IoT can help us to do that with lesser human efforts”, he said.
He explained further that there are wearable plant sensors at the moment, which is one of the top technologies in 2023.
The NITDA boss hinted that farmers can have a sensor attached to their plant to manage its health, watering, fertilizer, pesticides, and this would invariably enhance the increase of food produce.
He asserted that by 2050, Nigeria will be the third largest population in the world, therefore, there is need to explore how we can use IoT to increase the countrys food production.
In addition to agriculture, the NITDA Director General discussed the role of IoT in addressing security challenges, saying that IoT devices can monitor activities.

The DG emphasised that IoT could be utilised to enhance oil theft prevention by monitoring pipelines and sending alerts for quick security response.

He advised that there is also the need to develop the talent within the country.

ALTON Hails NCC Boss Over Quality Regulation

Published

on

The Chairman of the Association of Licensed Telecoms Operators of Nigeria (ALTON), Mr. Gbenga Adebayo, has praised the leadership of the Executive Vice Chairman/Chief Executive Officer of the Nigerian Communications Commission (NCC), Prof. Umar Garba Danbatta.
He also commended the NCC’s commitment to quality regulation, attributing the success of the telecom industry in the country to the regulatory environment it enjoys.
Speaking at a meeting with mobile network operators on the implementation of the Expanded Revenue Assurance Solution (ERAS) in the telecommunications industry, held at the NCC’s office in Lagos recently, Adebayo expressed his pleasure in what he called Danbatta’s remarkable administrative skills, challenging the notion that engineers are not good administrators.
He described Danbatta as an excellent administrator, highlighting his instrumental role in the growth and development of the telecom industry.
Addressing the audience, Danbatta shared details about the implementation of the ERAS project.
He emphasized the collaboration between the NCC and the Infrastructure Concession and Regulatory Commission (ICRC), saying the ERAS project is being carried out through a Public-Private Partnership (PPP) arrangement, following the  Design, Finance, Develop, Deploy, Operate, and Transfer (DFDDOT) model, as recommended by the ICRC.
Danbatta acknowledged the efforts of the NCC in transforming the dream of the ERAS project, conceived in 2007, and nurtured to reality.
He also underscored the project’s alignment with the Federal Government’s directive to enhance revenue collection and prevent leakages within ministries, departments, and agencies (MDAs).
By deploying the Revenue Assurance Solution, Danbatta said the NCC aims to optimize the revenue payable by licensed telecommunications service providers, thereby bolstering revenue generation for the government.
Initially designed to focus on telecom operators, who have not only become major industry players, but have also expanded their services to to the digital services ecosystem, the ERAS project underwent a significant expansion.
In June 2022, following a presidential approval, the NCC was directed to broaden the scope of the project to encompass the activities of Digital Economy stakeholders. Consequently, the project was renamed the Expanded Revenue Assurance Solution (ERAS).
The implementation of the ERAS demonstrates the NCC’s commitment to fostering transparency, accountability, and financial efficiency within the Nigerian telecom and digital services sectors.

Through the utilisation of accurate data and information, the ERAS aims to eradicate wrong computations, faulty data, and information leakages.

With the telecom industry playing a critical role in driving economic growth and enabling digital transformation, the ALTON Chairman’s commendation and the ongoing efforts of the NCC under Danbatta’s leadership highlight the commitment to creating an enabling regulatory environment that fosters innovation and sustainable development.

As the implementation of the Expanded Revenue Assurance Solution progresses, stakeholders within the telecom and digital services sectors eagerly anticipate its positive impact on revenue generation and the overall growth of the Nigerian economy.
