Laptop computer hardware and desktop hardware are almost the same in most specification, the concept of having bigger capacity of RAM will perform better in both laptop and desktop computers. So choosing your desktop computer hardware and laptop hardware will apply the same approach in most of its specification. Though in terms of portability having a laptop will be the sure winner but if you want heavier work then it would be advisable to have a desktop computer.

In most cases, Desktop computer will be more convenient when you detect computer hardware failures and it can be solved by replacing it by new computer hardware. Like if you want to replace or upgrade your CRT monitor into LCD will be much easier compare to a laptop as well as your keyboard, mouse, and etc. So if it is possible for you to have a desktop computer then it would be better but if you are a travelling businessman and need to use a computer every time and anywhere then vie for laptop. But the most feasible part of having a desktop computer is the capability of changing the part of the system unit; if you want to upgrade the speed of your desktop computer then it will be handier compare to a laptop.

It would be advisable to assemble your own desktop computer because you can limit the computer hardware to be installed, such that you can install 512mb RAM, 120gig hard disk, 256mb Video Card and a processor of 2Ghz or 1gig RAM, 80gig hard disk or 512mb Video Card and a processor of 1Ghz, it is by your own discretion then. Desktop computer hardware such like the hard disk, can be assisted by external hard drive which is widely available so you will not to problem about having a hard disk with a smaller capacity that your Operating System and important software can occupy. And also external hard drive will be convenient in terms of security of your important files, it serve as a backup storage as well.

Sometimes, hardware such like hard drive is still easy to see and locate, but nowadays computer hardware such as a hard drive will be located in the inner and not visible part of a system unit and must stay that way for your computer to do its task properly.

Finally, ask for more advice about how to protect your computer. Protecting your computer hardware will be a great aid to your computer as a whole. And if you want to have better and durable computers then invest for the branded and well – reviewed computer hardware.

To answer all of this we first have to figure out what the server is going to be used for. If we are doing heavy compilation on the server we will need a lot of RAM and a fast clocked CPU, if we are hosting a web server, the CPU clock speed is less important, but instead a server needs plenty of RAM. It’s important to know the minimum requirements for any application the server will be running.

What is a difference between a server and a desktop PC?

So you might be wondering what is the difference between a server and powerful desktop PC running an Intel i7 processor for example? Well there are two main differences, the ability of the server based system to utilize ECC memory (Error Correction Codes) and the sheer size of the memory that most server motherboards will accept compared to a desktop. Because the server usually run 24-7 while utilizing large amounts of RAM and usually operating at almost full capacity, it’s very possible memory errors can occur. To prevent a crash servers utilize ECC memory that uses Triple Modular Redundancy or Hamming Code as the primary methods of detection and elimination of errors. So if this will be a server that will remain on 24-7 and you will need more than 12 GB of rams (usually the maximum that will fit into a desktop PC), I strongly suggest going with a server level motherboard/CPU and ECC RAM.

Some good general guidelines to consider when picking the server hardware:

Is the server intended to handle multiple users, or is the server used in virtualization? If so depending on how many users are logging into the server, having lots of RAM is a good idea I recommend at least 12-16 GB depending on the server configuration and what level of virtualization the server will be performing.

Will the server perform complex calculations/compiling/rendering? If that is the case, I would recommend at least 12-24 GB of RAM and a fast multi core and even dual processes server with at least an Intel Xenon level processes or an AMD Opteron. (More to come on Intel vs AMD server CPU battle)

What is RAID and do I need it in my server? RAID or (redundant array of inexpensive disks) is crucial in a server. In case of a hard drive failure it could cost hundreds or thousands of dollars to restore the server back to its previous state, using RAID a simple drive swap and the server is back to its previous state. The most optimal array for a RAID controller in a server environment is RAID 5 or a RAID 1. A minimum of 3 drives is needed for RAID 5, and at least 2 drives in a RAID 1 configuration is required. I would recommend a hardware based RAID controller instead of a cheaper software based one. Having hardware based controller card removes the burden away from the CPU especially in case of a hard drive failure, having to rebuild the array would can cause significant system slow down if done without a physical hardware controller.

What hard drives should I pick for my server? Usually not only will the larger drives perform better because they have less number of disks so the access times will be faster, but they will guarantee you ample storage for the future. Depending on what your server is used for.

File Server or on a budget

I would recommend going with large SATA 7200RPM or 5400RPM 1TB+ drives with at least 32MB of cache. I recommend brands such as Western Digital, Seagate and there has been a lot of positive rave about the new Samsung Spinpoint F1 drives as well. Due to larger disk capacity, the dencity of each disk on the drive spindle is greater, this means that the reading head of the drive only has to travel small distance while reading data, this decreases seek times in drives and significantly improves performance.

High Performance Server:

I would recommend SAS 10,000RPM or 15,000RPM drives and if money is not an object SSD drives are becoming readily available and the price has come down since their first introduction. SAS drives are hot swapable, meaning you don’t need to shut your server down in case of a drive failure, simple pull the drive and the replace and the RAID controller will rebuild the data.

Picking the right server hardware is crucial in achieving smooth operations. I recommend to start by write down everything you want your server to be able to perform today and everything you MIGHT want it to do in the future. Now write down a number with a $ in front of it that will be the most you are willing to spend on this server. This will give you an idea of what type of server this will be and what hardware suites your needs the most, it becomes a balancing act between performance and budget but ultimately you are the only one that can make that decision.
