 How to Copy a Primary Harddrive- Copying Data to SSD Drive

 Picking  a New Solid State Hard Drive.

Why Write This?
Most people I know have heard about SSHDs and wonder what it might do for their own system, thats as far as interest travels. There is interest, muted by concerns about cost and reliability, stopped dead by lack of knowledge. I wanted to find out what was possible, in my own network and for others, at as low an experimemnt cost as possible considering the technology is fairly new.
I have friends who have SSHDs installed with good results. Their reports are glowing, so much so that I tend to take them with salt – more than the traditional grain!
So I set myself a very basic project: learn more and test that knowledge. This was done without highly technical involvement for personal information, in a rather unscientific process.
Getting Started.
I started by reviewing what was available. I found about ten possible brands and that all of the had two generations of device on offer. Based on this research I acquired some perfomance understanding and comparison.

Seeing some “sale” pricing, I set myself a very low budget of C$300 to purchase 2.5” devices (hopefully two) and dived in.

Informing Oneself: a very important step. This not just making a performance evaluation. I needed to find brands which I could comfortably expect to perform to my satisfaction. I found that brands available included both the traditional rotating drive maufacturers and well known memory sources.
There are, for sure, differences in quality, presentation and performance. These differences seemed small when compared with the more extreme difference between the spinners and solid state.

Setting Parameters: a rather difficult process if you want to be precise. In the interests of time I abandoned real precision in comparison. I set only two parameters: Price and Comfort Factor. I decided I was not testing the device, I would accept whatever performanc I could get at my price, this was going to be substantially better than a spinning drive. Comfort factor was more important in this exercise than comparison between suppliers.

Getting to Know Suppliers: I chose to watch the sales over the Christmas season. I found a retail supplier that provided me with what I wanted at a price close to my budget. This was more good luck than good management.

Getting to Know Brands: most of the available brands I already knew, two were entirely new to me. The specs for all these brands were similar enough that I eliminated that as a factor. My Comfort Factor was to hope that I could try out brands I knew. I was able to purchase two drives in November and late December from known makers. Fortuitously, the first I bought (500GB) came from a memory company, the second (1TB) from a well known hard drive maker. Both on sale at my budget range. Both my acquisitions are in what I regard as the slightly older technology.


The Testing Process

I had my test subjects, laptops in which to do the trials. At this pont I should add that I am a dedicated Linux fan. The operating system I prefer has performed well for me as my main system.
I am a very long time user of Slackware, also I have a Mint Linux laptop in use having switched from Ubuntu which I personally do not like. My dektop system is KDE which I love, that inspite of some recent “upgrades” which have effectively destroyed much of its flexibility. Shame on you KDE!

I have used both opeating systems to see perfomance differences between my spinning disks and the SSHDs being tested. I have also tried three other distributions in the process, Arch, Manjaro (in development) and Kubuntu (because I already had the DVD).

The Performance: there is a marked difference is speed of operation in anything depednat on disk accesses. I could see no difference between the 500GB drive and the 1TB drive in any of my tests. There is no doubt in my mind that the performance improvement over spinning drives is well worth the effort. Boot times are cut in half, applications generally run much faster (faster load, faster operation with data), netwok transfers and internet downloads obviously faster. Applications for me include Linre Office, digiKam and other related imaging applications. All are faster with the SSHD. I am ecstatic with my new found power!

Final Selection


In this experience I have no hesitation is recommending an SSHD as a choice if a laptop drive is to be replaced. I do not endorse a particular manufacturer.

Purchasing a new system may involve different considerations, such as preloaded software and operating system. If there is an option to purchase a laptop with an SSHD already installed – do it even at a reasonable difference in price! However, price is a killer at the moment as few units are available with the SSHD as standard. Given the retail price of a 500GB SSHD is now getting lower it is close to reasonable to convert provided there is no pre-installed restriction by the OS or the software you desire. For me as a Linux user it could be “no contest”.

The Comfort Factor should not be a concern. As I said the SSHDs I tested were made by firms I trust, either as memory makers or well established hard drive makers. I would suggest following that advice unless you get a really good sale price.

The Bottom Line


If you want to boost the performance of a laptop. Mine are five years old, an SSHD can do wonders. If the price is good even better. However, there is still a price difference making SSHD acquisition a difficult choice for most. I suspect this difference will narrow or disappear in the next ewo or three years.
I believe the device is reliable and has exceptional performance. Costs are coming down, in my opinion it is a wave of the immediate future.

What is a Network Attached Storage

 

Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. NAS [1] is specialized for serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance – a purpose-built specialized computer.[nb 1] NAS systems are networked appliances which contain one or more storage drives, often arranged into logical, redundant storage containers or RAID.

Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols such as NFS, SMB/CIFS, or AFP. From the mid-1990s, NAS devices began gaining popularity as a convenient method of sharing files among multiple computers. Potential benefits of dedicated network-attached storage, compared to general-purpose servers also serving files, include faster data access, easier administration, and simple configuration.[2]

Digital Marketing- Strategy,  Tactics and Value Mapping

 

Digital Marketing: Frameworks and References

Digital Marketing is about using websites and e-commerce portal to market your product and services.  Nowadays content management systems like WordPress, Joomla, DNN and Liferay are used for such purposes. These frameworks are open source and widely used as a  Digital Marketing platforms.

 

In implementing a digital marketing  a Competitive strategy, value proposition and tactics are very Important. The strategy, value chain and tactics are very similar to  traditional business marketing and sales only they are now implemented on a digital platforms.

Content Marketing is Important

Modern Digital Marketing  uses education based marketing and it is called content marketing. The objective is to use education and Information as the first class citizen in  the market place. The good old method of sale, sale sale is to be avoided in the modern Digital Marketing. Content Strategy is well suited in  complex product and solutions industry. An example will be Digital Marketing of software solutions.

 

 

Defining the Problem:

  Computerization and digital transformation of workplace is common in Canadian & US workplaces.  This means more and more computers, servers and cloud computing is injected in our dally life. Yet the basic questions remains to be asked, have we paid attention to the issue of maintenance and repair of modern computer infrastructure. The manual mode of IT support is not feasible and is economically constraining to be the least.

 

 As the digital transformation affects every part of business operation, IT maintenance and trouble shooting has remained stuck in the   1990s. Typical IT person can handle 10 computers and server and network, yet organization now has 200-500 PCs, Cloud and Servers. Does this means we must have an IT department of 50 people to handle 500 computers.   A strategic analysis of the maintainability  and scalability of Information Technology is necessary [10].

 

 

How A Real-Estate Development  Company  Avoided Cost and Time Overrun with Cloud Based Alfresco Collaboration Server

 

A Real Estate Developer save $10 million and more by avoiding Cost Overrun and avoiding Deadline Penalty

A Real  Estate  Developer in Canada was in the process of developing  a shopping mall  complex in Canada.  The shopping mall was  a complex development and communication and coordination was  of key importance. The list of departments that was involved in the project  approval are large and diverse. The list below is a partial summary:

 Customer Stories- Kerio Mail  Server Improves Customer Satisfaction

Customer Stories- Kerio Mail  Server Improves Customer Satisfaction

 

A   large municipal organization was in Email crisis. Its taxpayers were demanding immediate answer to questions they were asking  using smart phone  email.  In many instances, the conversation started over multiple years ago. Answering these questions required looking at the emails over multiple years and in particular searching the email database over multiple user computers.

 

To make the matter worse- many times emails were dispersed over 50 different computer mailboxes in multiple buildings.

 

Over the years the volume of email grew so much that it was not possible to store all the emails on the email client databases  like  Microsoft outlook and Microsoft outlook express. The volume of the email was far in excess over the max size limit of the email client. Switching to other email client like Mozilla Firebird was not a solution, since they  also have a hard size limit. As the size of email grew the email client startup time also become a problem. The central problem was of storing all the emails of every employee for at last 10 years so that accurate answers to taxpayer  questions could be returned.

 

It was at this point Keen Computer got involved with the customer. We examined the customer requirement and realized the customer needed a cloud based email server. For cost consideration Kerio mail server was chosen for the solution. Kerio Mail server provides continuous virus and spam protection. In fact, its virus and spam database is updated every 2 hours. The virus protection is significant, since many of the taxpayers personal computers were infected with virus and this was causing spread of virus through emails. By centrally removing and scanning all the outgoing and incoming email we were able to reduce the incidence of the virus infection by 99.95 percent. This was a tremendous achievement for the municipal operation.

 

Also, by storing all the user emails in a central mail server database, any person could use  the database for searching relevant communication that happened in last 10 years. There was no more missing emails over multiple building and multiple computers. Accurate answers could be given to taxpayers within minutes. This improved operational accuracy and customer satisfaction.

 

Also the hosted email server  provided mobile email access to the office email, This feature was considered mandatory for emergency personnel and bylaw officers. In short Kerio mail server was able to solve the  central issues of the business email. Kerio mail server  virtually eliminated the spam and virus from the corporate email. Each year the organization only had to purchase the antivirus and spam filter subscription at a fraction of the Initial cost.

 

 Email is vital for business today. A commercial grade email server is essential for business operation. In case you are experiencing email problems and want to discuss improvements in your business email, please contact us for details. Initial consultation if free , of course.

Disaster Management and Contingency

 

Summary and Value Proposition

 

Business continuity and disaster recovery (BC/DR) planning begins with a thorough risk assessment. Risk assessment is part of a larger risk management process found in most businesses. The four major components of the BC/DR risk assessment are threat assessment, vulnerability assessment, impact assessment, and risk mitigation strategy development.

 

In this article , we focus on threat and vulnerability assessment. In order to perform a thorough threat assessment, you need to look at threats and threat sources both internal and external to the company. It is often helpful to assess risk based on the potential risks to people, process, technology, and infrastructure.

People are not only the company’s employees but also its vendors, partners, customers,

and the larger community in which it operates. Processes are all the business

and IT processes used in the business. Processes are used to generate revenue, track

expenses, and manage operations from facilities management to human resources

and beyond.

 

 

Cost  Management as a Strategy in Enterprise IT Solutions

 

According to Macroeconomic analysis [1] of the Canadian SMB sector, 

a couple of interesting observation were made by  Bank of Canada:

 

1.0 Business  efficiency is unacceptably low

2.0 Operating costs are very high

3.0 Resistance to embrace Information technology and subsequent changes that it requires.

4.0  Lack of  Research and Innovation within general business  sector.

5.0  Monopoly in various sector makes Canada  noncompetitive.

6.0  An attitude of entitlement exists in various sectors.

7.0 Service sector has an attitude of getting away with fleecing customer.

8.0  Low accountability in salary and real output of an employee and an organization.

9.0 Non existing training facility for existing employees in SMB sector.
