The Future of Computer Storage
Posted on November 1st, 2009 No commentsMost computers today might have what has traditionally been a mechanical hard drive; a noisy metal rectangle shaped box about 3.5 inches wide that generates a lot of heat and has little metal platters inside that spin about several thousand times a minute and holds your data and computer programs. But there is a new challenger on the block that is taking the computing world by storm, and for very good reason: it is so much better.
Mechanical hard drives are very, very common. Trouble is, they are very susceptible to damage and wear. Yes you may have one that lasts years, but many a hard drive has been found that has “crashed”, that is, the little “arm” inside the drive that sweeps over the metal plates to read your data has either scrapped or seriously damaged the metal platters, taking all of your data with it. In most instances, your data is irrecoverable. They are also incredibly sensitive to movement and a simple accidental drop or bump (even if the computer is off) could potentially kill the drive pretty quickly. A painful lesson for those who do not have a recent (or any) backup of their data.
The new drives, called SSD drives (the SSD stands for Solid State Device), use a special computer chip for storing your data, and these gems bring with them many, many benefits. Some of these are; [1] Using less than a tenth of the power that traditional hard drives use (save on your power bill!), [2] Have absolutely no moving parts that can wear out, which eliminates any chance of mechanical problems, [3] They produce very, very little heat, whereas a mechanical drive can get so warm they are too hot to touch! [4] They can be bumped, dropped, prodded and left in extreme temperature conditions and still be fully functional. In fact, you can do all of the above to an SSD drive while it is turned on and it still won’t be affected, [5] they are really fast. SSD drives can read your data over 1000 times faster than mechanical drives. Yes, that fast.
The only disadvantage with SSD drives is the same for every introduction of a new technology; they can be expensive and offer lower storage capacity than current desktop systems might have. However, all that was months ago, and today, they are more affordable, offer more capacity and they are more popular than ever.
A drive that is ultra reliable (even when the drive eventually goes bad, data rescue is much easier), ultra fast, produces very little to no heat, uses practically no electricity to run and is completely silent. That sounds like the perfect device for your computer. Fast, Reliable and Affordable. Mechanical drives used to make us choose two out of those three options with a compromise on a third option. Today SSD drives offer all three. They work just fine with the new Windows 7 too.

What exactly is computer memory?
Posted on April 30th, 2009 No commentsMost computer users are confused between the two types of computer memory. There is the one type of memory that if you increase it’s capacity, you get a dramatic performance boost. Then there is the other type of
memory where if you increase that capacity, you get to store a lot more music, photos, videos, and the like. I sometimes get questions like “Will adding all of my photos from my camera onto my computer slow it down?” The answer to that question is no and I will explain why below.There are two types of computer “memory”. There is RAM (or Random Access Memory) of which the operating system and programs you see on your computer’s screen resides in and there is hard disk drive storage memory. RAM is the “fast” type of memory. This memory works so fast that its speed is measured in nanoseconds. Hard disk drives are the “slow” type of memory. This memory is so slow that its speed is measured in milliseconds. Hard disk drive storage is in the hundreds of gigabytes and it is a permanent storage medium for all your computer’s data (operating system, pictures, music, documents, etc). This type of memory should be thought of as “storage” rather than “memory” because that’s where the terminology can get confusing for some users. The real type of computer “memory” is RAM and it’s the kind that runs all of your programs in real-time until you turn off your computer. That’s why computers take a long time to boot up because it has to pull all the programs off the slow hard disk drive back into fast RAM before you’re able to work on the computer. RAM is volatile memory – all your stuff disappears as soon as the power is turned off.
Now here’s where things get interesting. If you try to load so many programs at once to multitask in, or play a very resource intensive game, database application, or CAD type of program, your computer might actually run out of its fast RAM type of memory. Then guess what happens? It has to use the slower hard drive for additional memory! This is called paging or swapping. It will take those unused running applications that are usually in the background or minimized on your task bar and put those onto the hard disk drive in order to free up RAM for the newly launched application. This is why one of the BEST things you can do to speed up your computer is to add more RAM. For Windows XP, I recommend no less than 2 gigabytes of RAM for today’s common applications. For Windows Vista, I recommend no less than 4 gigabytes of RAM. For the upcoming Windows 7, we will be able to run a very efficient computer with only 2 gigabytes of memory again, just like Windows XP, because Microsoft has really scaled back all the “bloat” that plagues Vista.So, if you find that launching multiple windows on your screen is very slow, then you just might need a RAM upgrade. Feel free to contact me for a free evaluation of your computer and its RAM upgradeability.
