Buying Tips Internal and External Hard Drive

My article will discuss about HARDDISK both internally and externally. Of experience I've had when buying a hard drive there are many factors and parameters that can make your selection switch. And most importantly, your interest in choosing a data storage media, here are some factors that might be a little help you in choosing and buying a hard drive either internal or external hard drive.


:: Internal hard drive ::

Internal hard drives are typically used for hard disk storage media devices in the CPU box, although there are sometimes used as a mobile hard disk / portable external hard drive with an additional connector. There are several parameters that must be considered in selecting the internal hard drive, among others, are:
1. Price
HDD which is produced by the official distrobutor accompanied by a warranty, then the price tends to be slightly more expensive. You can not claim warranty or service if there is damage to the distributor who bersngkutan, because of the serial number will terdeksi.

2. Brand (Brand sale)
There is still a company or vendor disk that already bankrupt, but its products are still circulating freely and commercially-belika. For example; Conner is not there anymore, but the brand is still on the market. If you want to increase the amount of your hard drive, try to buy the same brand with a long or hard drive before, so kecepatankinerja hard drive is not reduced quickly and remain visible.

3. Condition and age
For small-capacity hard drive {1.7G, 2.1G hard drive, etc.} can be used. But that should be considered when you buy a used hard drive, do not ever buy a hard drive that has been repaired {you would not know the extent of the damage on the disk itself}, it is clearly visible from seals that have been damaged or lost.

4. HDD Capacity
Before you buy a hard drive, first determine how much capacity is needed by the operating system you will use. It greatly affects the remaining hard drive capacity that will be used as data storage, etc.. Do not ever take into account the difference in the nominal price of hard drive you want to buy. Remember, the seller just trying to spend a stock, but you buy a particular purpose.

5. Speed
Maximum transfer rate, do not take on this slogan. Speed ​​figures usually obtained
of the transfer speed between the computer memory cache disk, while to figure out a better figure is the sustained transfer rate, because it shows the real transfer speed between the drive and computer memory. The best way to find out is to try to speed read and write commands are actually.

6. Rotation or rotation
Quick data loading, meruapakan one proof that your hard drive has a number Rpm (rotations per minute) high or greater. For example; harddsik 7200 Rpm premises will be much demand for a fast processor or for gaming or graphics application.

7. Controller
Note the speed of the hard drive and controller, especially for SCSI hard drive. Hard drive faster but has a slow controller, the disk speed is only equal to the speed controller, and vice versa. A system operating at its slowest component. This should be considered compatible between the two.

8. Check with Utility HDD
Would have been very urgent if we are discussing is about the examination with the utility of the condition of the actual hard drive, which is hard to know whether or not there is a bad sector. First, it must first use the Fdisk, then you format the hard drive, then do check the cylinder area using Scandisk command. However, you can also use a utility better, using Disk Manager.

:: External Hard Drive ::


External Hard Drive mobile storage media that can be used and taken everywhere that it is usually a portable. There are several classifications which may be a consideration in choosing and buying this external hard drive. Parameters and classification of them is:

1. Capacity (maximum file)
Portable hard drive storage capacity varies, starting from 40GB to 500GB. But now also appears that a portable hard drive reaches maximum capacity 1.5 TB (terabytes). If you are a lot of work with video and graphics files, we recommend choosing a portable hard drive with the largest capacity you can buy.

Intended as a supplement in addition to the hard drive in a desktop computer, portable hard drive is now just mostly targeting users of notebooks and netbook markets (mini notebook). Portable hard drive which is aimed at notebook / mini notebook comes in two sizes: 2.5 "and 1.8". But you also are not prohibited from choosing a size of 3.5 ", although this one is usually aimed at desktop PCs. Of comfort carry it will be different. In addition, the price of portable hard drive 1.8 "would be more expensive than 2.5", though both are exactly the same capacity.

2. Play Speed ​​Drive
Disk rotation speed is partly determined by the speed of data rate, and is expressed in rpm (rotation per minute). Generally, portable hard drive spinning at a speed of 5400rpm.

3. Large buffer or cache
The amount represents the amount of buffer memory is cached, or stored which can be handled by a drive while waiting for a request (request) from the system next. The amount of buffer ranging from 2MB - 16MB. The larger the buffer size, the more data can be stored and faster delivery of data. However, the larger the buffer size that packed a portable hard drive, the more expensive the price of portable hard drive is.

4. Recovery Features
Pick a portable hard drive comes with backup and recovery features. This feature is useful when your files are damaged or data corruption due to loss of power intake of a sudden, or due to virus attack. Through the recovery feature, you'll be able to recover data lost / damaged.

5. The ability of a PnP (plug and play)
Plug the cord and a portable hard drive can be used directly without the need to install any drivers or software, so intent PnP. PnP capabilities especially necessary if you intend to use a portable hard drive on multiple computers - PC in the office, outside the office netbook or notebook at home.
