How can I choose the best hard drive on your desktop?
Hard disk selection is actually a very simple process. Since hard drives have very few specifications and many of them are common to large groups of drives, one is much easier than it can appear. The first step is to decide whether you want an internal or external unit and then decide on the type of connection. Then the decision may have the most impact of capacity, transmission speed and time search.
The first main choice when selecting a hard disk is whether you want an internal or external unit. The internal drive is generally cheaper and does not require additional cords or separate performance, but you must install it yourself. The external unit needs a computer connection and almost all needs to be connected separately, but are easy to install, portable and often ready to use in minutes.
Another steppe determines the type of connection available for your hard drive on your desktop. InTerric connections are generally integrated power electronics (IDE) or serial advanced technological connection (SATA). Some motherboards have both types of connections, but most of them have one or the other. If you have a choice, SATA is generally considered to be a better choice. External units usually use universal serial bus (USB), firewire or external serial advanced technological connection (eSATA). While USB is the most common unit and port style, ESATA is the fastest and most stable, followed by firewire and then USB.
Many users select the hard drive on the desktop based on its storage capacity. The size of the unit is usually measured in gigabytes (GB) or terabytes (TB), with terabytes larger. The size of the unit is always administered before formatting; After formatting, the drive loses about 10% of its total capacity.
The second common method of selection of the unit is based on its transmission or spindle. Transfer speed is how long it takes to move the stored infOrormation between the unit and the computer. Some units do not have a specified transmission speed, so the buyers use the spindle speed instead. This is how fast the storage space inside the drive spins. In both cases, the higher the number, the faster the transmission is.
The last common measurement is the time of searching. This amount is listed in milliseconds. The lower the search time, the faster the unit is capable of accessing the stored access. This is one of the few areas where you want the lowest possible number. The average hard drive on the desktop has a search time around 10 milliseconds.
