HDD replace by SDD in old Dell 5520 laptop

Last year I have installed SSD in my old laptop Dell 5520. Idea was to get better performance, especially after upgrade to Windows 10. Even they say Windows 10 runs faster, but I don’t agree with that statement.

I started by comparing SSD models and prices. My final choice was between “Crucial MX200 2,5″ 250GB” and “Samsung 850 EVO 250GB”. Both hard drives cost (at date 2015-07-..) around 100 eur. Will 250 GB will be enough? For standard home user it is more than enough and I personally have bunch of external hard drives and one NAS running on my LAN.

Below is a video how to do the replacement of HDD in a laptop. If video will be not shown in the future, all Dell laptops are similar, so look for similar model. All replacement is pretty easy, even doing it for the first time.

If you are upgrading to Windows 10, like I am, at first do Windows upgrade and activate your Windows license. After that you will be safe to change your HDD and Windows license remains. As you maybe already have heard Windows 10 license is coupled with computer hardware configuration. So if too much hardware will change (like motherboard on a laptop), your license can stop working.

I also used some disk partition cloning tool, to copy all my data from HDD to SDD, so I didn’t need to reinstall Windows at all. System booted like a charm. All programs and files there in their places and Windows was up and running. It has saved me a lot of time, so my recommendation goes to “EaseUS Disk Copy Home”, because it is also free. Note: make sure you have less data in HDD than total SSD size, otherwise copying all data not fit. It is possible to copy single partition (for example, only C drive).

What does it feel running old laptop with SSD? I really felt boost of performance: Windows was starting and reacting faster, all software, apps and games were running faster, copying huge and small files was super super fast. Appreciable speed increase from laptop for me was at least 2x-3x times.

I have run benchmark tests before and after hard drive replacement, so I could show difference between old HDD and the new Samsung 850 EVO 250GB performance. By the way, the Dell 5520 has SATA II connection, which is still enough to reach maximum of SSD performance (540 MB/s sequential read and 520 MB/s sequential write).

If you look only at plain numbers, hard drive read\write speed increase varies from 6-398 times for read operations and 6-290 times for write operations. The biggest increase is for small size chunks copying. Even these numbers are already amazing, additionally SSD performs a lot more IOPS (Input/Output Operations Per Second) than HDD.

It is really worth do such replacement if you only want faster computer, but you are satisfied with everything else on the machine. I have now already changed all my laptops to run with SSD and I am planning  to help my non-technical relatives to do the same. I don’t see a reason why I should spend money by buying new machine, while I can replace single part to extend computers lifetime.

Facebook shares insights from their development process

Facebook growth speed and development scale is enormous. Even you can’t work at Facebook you still can learn how they do coding, releasing, monitoring and what tools can be useful to you too.

Facebook qualities:

  • delivering fast, to be the first a market
  • delivering high quality software (reliability, performance, user experience)

I find 26-30 (hacker series) the most interesting talks as a developer. Good source for new ideas.

Fix Resharper Go to everything in Visual Studio 2013

Some time ago I got a new dev machine. So I needed to install again all my development tools, Visual studio, MS SQL, etc. Luckily with help of Boxstarter and Chocolately this time consuming and not so interesting work (bigger part) can be automated. But usually were some annoying tweak and tune settings which are not or can’t migrated or forgotten to migrate.

Somehow I had not backup of my Resharper settings file, so I needed to change few settings from defaults. The most difficult one was get get rid of navigation to object explorer (default VS behaviour for external assemblies when using CLTR+click). I wanted to see decompiled sources of external code. Here is the setting you need to set in Resharper Options:

Domain buying fraud\scam

Recently I decide to sell one of my domains. After a few days I was contacted by someone via email. Probably he got my email from checking domain’s whois information.

From (1):


I’m a broker of an investor who would like to buy

My investor has six figure budget for 75-80 domains.

Please email me your desired price.

How can we transfer money to you (wire transfer, escrow)?

If you have other names please email me the list. I may help you to sell them.

My answer was simple. You can buy the domain via Sedo and I have provided the link. Next day I got an email back.

From (2):

 I’m not interested in transactions under $1000. My client pays me 10%-15% on every sale.

May I suggest to change your price to $5000? In this case I will earn a better commission.

I hope you understand my business model better now.

I started to smell something, so for an experiment I have increased the domain price from few hundred Euro to several thousand. After that I notified “the buyer”.

From (3):

4499 eur –  Ok.

Before my client buys he will need one thing from you:

To be sure in legitimacy of this sale and to avoid possible trademark problems my client buys domains certified by an official certification authority.

The certificate my client needs must include two things:

1. Independent manual valuation of the market price. My client does not trust automated valuations. It must be a manual valuation. The expert evaluation will help to determine the true value of your domain’s worth so you can maximize profits during the sale. On the other hand, it minimizes risks of my buyer.

2. Trademark infringement verification. It proves your domain has no trademark problems.

If your domain has been certified please email me the certificate and we will proceed with the sale. If you don’t have a certificate I may send you a link where you can obtain it. Please don’t worry. It won’t take much time and money. It takes 1-2 minutes to order it. The results will be sent to you within 24 hours. Then you send me the certificate via email and we’ll proceed with the sale.

As a broker I’m very interested in a good valuation part of this certificate because my client pays me a commission (10-15% of the sale price) on every domain purchase.  You can read suggestions about choosing a right certificate agency at (“Domain Broker” is my nickname).

The process is very easy:

1. Go to the Certification authority site ( and order a certificate for your domain. Just enter your domains in the “Domain List” field at Certificate Order Form ( and specify in the “Comments” field you have a buyer with $X,XXX offer so you need an evaluation near this value.

After 24 hours you will get the results. If the appraised value in your certificate comes higher he will increase the offer accordingly.

2. Then send these results via email and we’ll proceed with the sale.

What a surprise. I need to spend a small amount of money to get a big amount of money. 100 % scam\fraud\phishing schema. I started checking everything what I know about this guy:

  • Email of the “serious” buyer is a free email box, not a company email. After I asked him about it, he explained me that he doesn’t need such “brand” email.
  • Provided address points to an empty building. Thanks to Google street view you can be a detective very easily.
  • Domain is fake one, to make you believe it is found via Google or something similar. Only one page is available and the domain is registered only few months ago: I even saved discussion page to pdf for the future readers Google Answers_ Can someone recommend a good appraisal service with a trademark verification_
  • The same applies to “Certification site”. Very young site (few months old) with a style of year 2000:

What I did next, I have “placed an order” for evaluating my domain.

From (3):

Dear Customer,

You have submitted your domain for the certification. We will help you to certify your domain in 4499 euro range.

Please pay for the service at
After we receive your payment we will certify your domain. It will also include the TM verification. The results will be sent to you within 24 hours.

Here you see a new scam domain (, which points to the same site as Payments site ( probably has nothing to do with this fraud, but I am not sure.

I hope I have helped all the people who will be looking for information about this domain buying fraud. In general, be smart, think at first and don’t forget to check on the internet.

Google “frauds list” to see how many deceptions there can be . If it is too good to be true – then it probably is not real.

p.s. The funny thing is, that all domains are hosted in the Netherlands (NL), where I currently live. I hope the bad guys are not my neighbours 🙂
