About Cisco
Cisco's approach to quality can be condensed down to one phrase: "ensuring our customer success". The information contained in this section will help you to gain a better understanding of Cisco's Business Management System, which allows us to accomplish that success. Cisco's Business Management System is made up of two parts; the Quality Management System and the Environmental Management System.
Cisco Fun Facts
Cisco Systems, Inc. is an American multinational technology conglomerate headquartered in San Jose, California, in the center of Silicon Valley, that develops, manufactures and sells networking hardware, telecommunications equipment and other high-technology services and products. Through its numerous acquired subsidiaries, such as OpenDNS, WebEx, Jabber and Jasper, Cisco specializes into specific tech markets, such as Internet of Things (IoT), domain security and energy management.
Cisco is the largest networking company in the world. The stock was added to the Dow Jones Industrial Average on June 8, 2009, and is also included in the S&P 500 Index, the Russell 1000 Index, NASDAQ-100 Index and the Russell 1000 Growth Stock Index.
Cisco Systems was founded in December 1984 by Leonard Bosack and Sandy Lerner, two Stanford University computer scientists, who pioneered the concept of a local area network (LAN) being used to connect geographically disparate computers over a multiprotocol router system. By the time the company went public in 1990, when it was listed on the NASDAQ, Cisco had a market capitalization of $224 million. Cisco was the most valuable company in the world by 2000, with a more than $500 billion market capitalization

Learn more about Hard Drives
Everything You Want to Know About Hard Drives.
Understanding hard drive basics will help you make better storage decisions.What's a Hard Drive Do?
A hard drive is the hardware component that stores all of your digital content. Your documents, pictures, music, videos, programs, application preferences, and operating system represent digital content stored on a hard drive. Hard drives can be external or internal.
Everything stored on a hard drive is measured in terms of its file size. Documents (text) are generally very small whereas pictures are large, music is even larger, and videos are by far the biggest. A hard drive determines the size of digital files in terms of megabytes (MB), gigabytes (GB), and terabytes (TB).
There are 3 major versions of hard drive technologies. All of them have pros and cons and reasons for owning each versions;
Standard Hard Drives
- This is an older technology but has continued to evolve in speed and reliability. Basically the technology is like a record player except the platters are metal instead of vinyl and the needle is magnetic allowing you to read, write and erase. The faster the hard drive spins, or RPM, the faster the read and write happens.
Pros -- Cheapest per GB, very reliable and easily replaceable.
Cons -- Much slower than newer technologies.
Solid State or SSD Drives
- Solid State is basically a form of memory that can be written to and the data will stay saved even with the power off!
Pros -- Very Fast read/write, no moving parts so it is quiet and in theory should last longer, less heat and energy.
Cons -- Price per GB is more expensive than Standard HDD.
M.2 Drives
- An M.2 SSD is a solid-state drive (SSD) that conforms to a computer industry specification written for internally mounted storage expansion cards of a small form factor. Shaped like a stick of gum. Most M.2 SSDs are 80 x 22mm (L x W), but they can be shorter or longer. You can tell what size an M.2 SSD is by reading the four or five-digit number in its name: the first two numbers are its width, while the others are its length (example: M.2 Type-2280).
Pros -- Small for factor and SPEED,!!! M.2 card can use either the existing SATA 3.0 specifications and be restricted to the 600MB/s or it could instead elect to use PCI-Express that provides a bandwidth of 1GB/s under the current PCI-Express 3.0 standards.
Cons -- Compatibility, since this is an internal storage device your motherboard must be newer and include the proper slot(s) to accommodate this storage technology.
Hybrid Hard Drives
- A Hybrid Hard Drive may be the best of both worlds. In a Hybrid Drive you have both SSD and Platter or Standard Hard Drives included in one device. Typically you have a smaller SSD Drive coupled with a larger HDD. You have the low price per GB of an HDD and the speed of an SSD. This type of drive is a great choice for SMB workstations all the way to gaming machines.
Pros -- Best overall value for the dollar as well as speed ratio.
Cons -- Can add a level of complexity to some users as you basically have 2 drives in one and will have to be aware of what drive you will save data vs programs to.
If you have an older Computer or notebook consider the SSD option as it will make your system feel new again with this faster storage technology.
Internal vs. External or Portable Hard Drives
External desktop hard drives are built using a drive and require an AC adapter plugged into a power outlet. These drives are a good choice for supplementing a desktop computer or plugging into a laptop's home base, and typically can extend your need to upgrade your hard drive or more importantly it can be used as a backup drive. As the saying goes "It's not if, but when something fails!" Please Backup...CompSource wants this to be as easy and stress-free as possible.

I've been an IT consultant for most of my life and one of our mantras is -fast, good, and cheap. you never get all three!- Somehow CompSource does it. I'd ordered a portable air conditioner from two other vendors and both strung me along and finally cancelled my order *after* charging me since they apparently couldn't either manage stock or suppliers properly. I eventually got my money back but I was worried up getting gouged with summer "on season" pricing. I found CompSource had a unit almost identical (different branding) and thought I'd give it one more try. To be honest it looked too good to be true. Price with shipping was over $100 less than the competition. I was shocked that it arrived almost as fast as I got the *tracking number*. I ordered on a Friday and got the FedEx tracking number on Monday from Rich Burson and had the unit Tuesday evening. This is a nearly 100lb 12K BTU beast that I would have expected to take at least a couple weeks to get. I sent a quick thank you email and who replies? The President of the company. Personally. Smart guy. I used to check Newegg first. Not anymore. Thanks! MikeMore Reviews
