How to Choose an External Hard Drive

Choosing an external hard drive depends on several factors, such as how often you plan to use it, how much memory you need, whether you need a portable drive or you plan to keep it in one place, etc. Each of these factors affects both the cost of the disk, and its type.

The capacity of the disc

Most external hard drives can hold a 2 GB to 4 TB of data. There are also models a volume of 8TB. To determine how much memory you need, decide what you plan to store on disk. If you are looking for a carrier to record large amounts of video, consider buying a disk capacity of 1 TB. If you need a medium for storing emails and text documents, you will approach the compact size of drives that can accommodate several gigabytes.

The data rate

The speed with which information is recorded on the hard disk, are also very important. If you plan to use the drive for backup data recorded 1-2 times a week, you can use any external drives. If the vehicle you need for everyday use, including for writing large files, it is best to select a drive with high speed recording. The USB 2.0 interface is still common, the speed is quite high, but for writing large files is preferable to use USB 3.0, which speed is much higher. The eSATA interface is even more perfect, but drives with this interface are expensive. Choosing a connection interface, note the presence of your computer corresponding connectors.

Portability

An important factor in selecting an external hard drive is a way to use and store. If you are looking for additional, external storage device, which does not plan to move from place to place, the perfect option for you will be the big wheels in size, but can accommodate large amounts of information. They usually need their own power supply from the mains. These drives are slightly cheaper portable devices of comparable capacity. Portable Hard are compact, have high strength, protecting them from falling, and do not need a separate power adapters. They are most often used for frequent transfer of information from one device to another, as well as for work purposes, when all necessary information is always available at your fingertips.

Security

Storage on an external hard drive is confidential information relating to personal data is quite dangerous, especially if the disk is often connected to various devices. If you use it for such purposes, be sure to check availability hardware data encryption. This encryption is much more secure software.

How to Choose a Flash Drive, You Need to Pay Attention

In the real world, everyone has a flash drive. Many have already bought many will buy. Like it or not, it is an attribute of our lives. They are used by almost all digital devices, since MP3 players and finishing with a TV. But many do not know how to choose the flash drive. You should pay attention to, and what to choose for a particular device. That’s about it and will be discussed in this article, the correct choice of flash cards.

The Speed of Reading and Writing

All memory cards vary its speed. Write speed read / write depends on the model of the most flash card, note not from the manufacturer. Normally memory card speed is written as on the packaging, on the very same flash card. Below is a table that written mass storage class ratio and speed, everything is simple.

As you can see, identify memory card speed is not so difficult. We now consider where what speed is best to use. Many will say, “The higher the speed, the better. “, But it is not so. After all, the idea of an overpayment for the flash card, it makes it clear. After all, the higher the speed the memory card, the higher its price.

An Interface for Memory Cards

Today, there are three types of memory cards: is the USB 1.0 (1.1); the USB 2.0 (an eSATA +); the USB 3.0. The first guess is not offered for sale, since they were created in 1996 and more are hardly used. But USB 2.0 still common type of memory card (e.g. the memory stick key), they support high-speed operation with devices of this type. And have the function as a “Hot use” or as they say “hot-swappable “, meaning it is what it used to before removing the flash drive from the laptop, it should disable the software. The new interface USB 3.0 already supports speed of up to 5 gigabytes per second. It also supports the USB 2.0 we do. Such an interface has increasingly become encountered in the new computer technology and gradually replaced the older.
