How Large, How Fast? Choosing The Right Hard Drive Size And RPM

One necessary and extremely important component of computers is the hard drive. The hard drive stores your games, applications, music, pictures, videos, and documents. As such, you should be sure the notebook computer you’re thinking of buying has a hard drive that can give you the storage and performance that you need.

There are two important considerations when looking at hard drive specifications for your computer notebook: hard drive size and hard drive RPM.

Hard Drive Size

Hard drive size simply refers to the data storage capacity of a hard disk drive. Desktop computer hard drives offer sizes of up to 500 gigabytes (GB), while notebook computer hard dives offer sizes of up to 160 GB. Notebook computer hard drives are more expensive than desktop computer hard drives with more than twice the capacity of the notebook hard drive. This is due to the engineering difficulties inherent in making high-capacity hard drives for the smaller notebook computers form-factor.

A notebook computer’s hard drive size indicates how much data a notebook computer can store. If you are interested in storing large amounts of movies, pictures, or music, you want to go with a larger hard drive to avoid running out of space.

A hard drive’s size has very little to do with its performance, unless the drive is almost full. The Windows NTFS File System requires a minimum of 10% of the hard drive to be free space for optimum performance, and it frequently requests as much as 15%. This means that, on a 40 GB drive, Windows prefers that you use a maximum of 34-36 GB, leaving 4-6 GB of space unused. On a 160 GB drive, Windows prefers that you use a maximum of 136-144 GB, leaving a massive 16-24 GB unused. If you start to go over these Windows storage limits, you may notice your computer’s performance taking drastic hits.

Hard Drive RPM

Hard drive RPM is a hard drive’s rotational speed, measured in revolutions per minute (RPM). Desktop hard drives now have speeds as high as 15,000 RPM. Notebook hard drives, on the other hand, currently have an RPM ceiling of 7200 RPM.

A hard drive’s RPM indicates how fast the drive’s spindle will move or how fast the hard drive platters will spin. The higher the spin rate is, the shorter the seek time and latency will be. This translates to quicker data access and transfer.

How Large and How Fast

The greater the free space and the higher the RPM, the better your notebook computer’s performance will be, so go for a slightly-more-than-comfortable size and the highest RPM for your notebook computer’s hard drive. A large hard drive gives you the option to expand in the future, and you can never go wrong with a notebook computer that can give you fast access to your stored data.

It is even more crucial that you go with the top-of-the-line hard drive size and RPM for your notebook computer if you are fond of computer games, you have a lot of multimedia files, or you want to be able to easily upgrade your programs. These games, content and programs take up a lot of space. A high RPM hard drive can also cut down on game load times, giving you more time enjoying your games and less time staring at loading screens.

Panasonic Digital Camera - Get Animated About The Digital DMC-FZ5!

When Panasonic Digital Cameras introduced their Lumix DMC-FZ5 they brought some real color competition into play for this class of camera!

On the one hand this Panasonic digital camera is a real step up from its predecessor - the DMC-FZ3 - in terms of color accuracy. On the other hand it also outperforms many cameras in its type and price group when it comes to true color rendition.

As such - and incorporating the same Leica-branded DC Vario-Elmarit zoom with its 12x optical range as the DMC-FZ3 - this digital camera is a serious contender in the higher-end prosumer market, as Panasonic digital camera reviews point out. This lens system contributes to a very good image resolution.

Having said that, expert consumer photographers might very well expect to be able to manipulate those colorful image files in RAW format, whereas the DMC-FZ5 only supports TIFF.

One of the most appreciated features of the Panasonic Digital Camera DMC-FZ5 is its highly effective Mega Optical Image Stabilization system. It comes with two modes of which the first offers continuous image stabilization, which is said to assist during image composition.

The second mode - which reportedly is even more effective, only comes into play during the actual release of the shutter.

This Panasonic digital camera also features a real-time histogram, which is always welcome on a digital camera. This ensures that you get a balanced exposure and not blow away the highlights! It is a challenge to learn how to interpret a histogram instinctively in the field, but worth the effort for the improved results you will be getting.

A handy feature highlighted in Panasonic digital camera reviews, is the ability of the DMC-FZ5 to record sound with still images. If you have a number of similar objects to record, the 5 second sound input can help you make sense of your pictures afterwards!

As far as power consumption is concerned, the Panasonic Digital Camera DMC-FZ5 has a sleep mode to conserve power, and will then retract the zoom lens. It can be set to come into action after 1-10 minutes, or when you press any button. It uses a proprietary rechargeable battery, with a charger included. Battery life is longer than with its DMC-FZ3 predecessor.

If you’re tired of serious photography and want to play around a bit, this Panasonic digital camera offers you an animation feature. It lets you take a number of sequential-movement stills which you can then transform automatically into a movie sequence.

So if you or the kids have some clay lying around, this feature could keep everyone suitably amused for an afternoon…

If not, it will be just as easy to enjoy hours of entertainment discovering all the superb features of the DMC-FZ5 Panasonic Digital Camera.

Military Laser Pointers - Dangerous Military Grade High Power Laser Technology In The Wrong Hands

Its no mystery that many military organizations throughout the globe incorporate the use of various laser devices into their entourage of weapon systems. It seems the value and versatility of high power lasers has worked its way beyond contemporary science and astronomy, we now see laser pointers and other powerful laser devices at the forefront of the modern day battle field. There are many clear combat advantages military laser pointers provide to today’s foot soldier. Whether mounting the laser diode as a laser sight, or a high power laser pointer for pointing out enemy locations, or even underwater reconnaissance, there is no more useful tool than a military laser pointer.

It makes good sense to provide funding to military personnel for standard issue military lasers, not only as a weapon, but also as a life saving device. Many times a high power laser pointer is the only “homing beacon” a platoon or squadron can rely on to be retrieved during a gunfight or a failed operation. A high power laser beam is clearly visible through daylight and the night sky, and the most popular military laser pointer in production produces a powerful green laser beam at a light frequency of 532nm. This is because the military finds the greatest use in the brightest laser color possible to the human eye, the green laser beam. Many military lasers are so powerful that they can actual light a fuse, temporarily blind an enemy, burn, and ignite, making them great for protection and intimidation.

There is, however, a bit of controversy surrounding the availability of military laser pointers on the open market through online shopping sources. The debate is that extremely powerful laser pens, which can be considered dangerous, are too easy to purchase and use despite clear health and safety hazards that they create for un-trained users. The problem is that many people were taking advantage of military grade technology from the comfort of their own home, receiving wonderfully packaged powerful laser pointers to their front doors. To some, this may seem harmless, but the media has created a shroud of fear surrounding the concept of laser pointers, most especially, high power military lasers. When news hit the nation that a laser pointer had been used to blind a pilot on his descent to land his filled aircraft on an international air strip, immediate action was demanded by the public from both the FDA and Home Land Security. The unfortunate truth was that the laser pointer that was actually used was a low power 5mw green laser pen, not your average high power military laser pointer. Despite this knowledge, leaps and bounds were made extremely quickly to keep powerful military lasers out of the homes of your average civilian.

But laser hobbyists around the world have not backed down at all, in fact, laser sales worldwide have steadily increased year to year since the wide scale release of the green laser pointer at the dawn of the millennium. More powerful military laser pointers are being sold today than ever before. But there is some difference surrounding the laser pointer scenario currently. It seems that your average laser pointer enthusiast has gotten smarter and is now taking standard safety precautions when using their powerful lasers. Simple things really, such as not aiming the laser at any person, animal, vehicle, or building. Things that really anyone with a little common sense should be able to grasp, but when you are holding a powerful laser pointer capable of blazing a beam of light over 65 miles, its easy to get carried away. The military will continue to use laser pointers, and laser providers around the globe will continue to provide military laser pointers to laser users as long as the desire for more power exists.

James has been involved with testing and designing of military laser pointer for over three decades. He has written extensively about positive use of military lasers in global armed services. His preferred provider of military laser pointers is United States based ThinkLasers.com
