What Is The Best Value Computer You Can Buy?: Part 4

Continuing with the series of posts of the best value components you can buy for your computer, this section is all about RAM. RAM is a component of the PC which is essential to performance and depending on a number of factors, the ideal amount of RAM can differ from person to person. RAM also has one wonderful quality, it is dirt cheap! This gives you little excuse for skimping on it but there is a point where you will be spending a significant amount of money for very little gain in performance.

The Perfect Laptop – Impossible

Laptop keyboard

Recently, I had to come up with the task of choosing a new laptop to buy. It seems like an easy task until you actually try it. Everywhere you go, every brand, every model - nothing is perfect! You start off with a good idea of what type of laptop you want, the amount of power, the battery life and you find that this laptop you've been picturing in your head simply doesn't exist.

Personally, I wanted a laptop which had a decent graphics card, at least an i5 processor and an anti glare screen for around $1700. The problem being that no one who wanted an anti glare screen had any need for a powerful laptop so you either had to go for an under powered laptop with the screen you want or a laptop with all the power you could need but a screen you can never see unless you close all the curtains and turn off the lights. Anything which looked to be perfect ended up costing around $3000 because it had all these other features which i had no need for.

I'm sure other people have had similar dilemmas when trying to buy a computer, there is nothing which quite fits everything you require for. This means that your purchase ends up being a series of trade offs. For me, I valued power so I got something which was not very expensive, had heaps of grunt and had a full HD screen (still glary). It seemed like an almost perfect laptop, until when I brought it home. I realised it only had a 1.5 hour battery life!

New memory invented which can last a Billion years!

Invention

Scientists are reporting successful tests of a new memory device that could allow terabytes of data to be stored without corruption for millions of years

The device is an iron nanoparticle, 1/50,000 the width of a human hair, enclosed in a hollow carbon nanotube. The iron can be shuttled back and forth within the tube as an effective way to store data.[ad#Adsense]

The team says it’s achievable to build storage devices capable of carrying a terabyte of information per square inch, making it more effective than current techniques. However, the data will also be almost incorruptible and should remain available for a billion years or more.

Current memory technologies are nowhere near as long lasting. Conventional flash memory usually fails after around three to five years.

As an example Alex Zettl, one of the team behind the invention, notes that the Doomsday Book written on vellum has so far lasted over 900 years, whereas the digital version of the book, encoded in 1986, failed in less than 20 years.
