January 24, 2018 / no comments, on blog

To buy an ideal external Hard Disk, the consumer should be aware of some important aspects such as storage capacity demanded, operating system compatible with the computer of use and portability of the device. TechTudo has put together 10 tips that can solve your doubts when choosing an external hard disk. Learn how to care for and maintain the appliance.

External HD may be an alternative to saving files off the computer

  1. Think of internal space when buying a HD

Knowing how many gigabytes or how many terabytes the external hard disk displays is essential to set your purchase. Not always the models with larger space are the best option, because their need can be more modest. The important thing is to choose the HD that matches more with the use you make of the computer.

If you are a more casual user of computers, a 500GB hard disk can meet your primary needs. You probably need a device to store only text, photos and some videos. In addition, these files can be saved to cloud services. Sony HD-EG5 has 500GB and goes for about $ 350. With this space, you can store 100,000 photos of a 6-megapixel camera or 125,000 MP3 songs of 128 Kbps, for example.

But if you’re a gamer, your need will be greater. The average space for a medium-sized PC game is between 2GB and 3GB, but the size doubles or goes beyond high-end graphics programs. In addition, you need RAM and a good GPU so that the game is processed without problem. In the case of HDs, at least one model with 1TB of space is recommended. Seagate’s Expansion offers 3 TB for about $ 700, ideal for this user profile.

Graphic artists or video editors can opt for both external HD and cloud services, especially if it is not confidential material. WD’s My Cloud mixes hard disk functions with virtual storage, with 2TB of space, enough for audio-visual program files.

  1. Search for which operating system is compatible with HD

Typically, all external hard disks are compatible with Windows and Mac OS systems that dominate the majority of the desktop and notebook market. The handsets are compatible with only one of the two, since Mac uses the standard HFS +, while Windows runs with NTFS.

At the time of purchase, check with the manufacturer for actual compatibility. On the Mac, there is a program called MTFS-3G that reads HDs compatible with the Windows system. And the best: the software is free.

When purchasing an HD, if the component does not work on your computer, check the Internet for any disks or programs that enable operation if possible. Very old versions of operating systems tend not to work with new equipment.

  1. Look for portable devices

HDs change greatly in size, according to the hardware characteristics. The model Sony HD-EG5 weighs 380 grams and fits in the pocket, while the Seagate Expasion weighs more than 1 kg.

If you are buying a larger model, choose one that will compensate for the large memory space or for the high speed in data transmission. But do not choose an excessively heavy HD so as not to compromise your data on an eventual physical transport. Always remember your needs when choosing a product.

  1. Care about data transfer

Give preference to HDs with USB 3.0 input, three times faster than its version 2.0. Today most of the accessories have this type of entry more modern. But to avoid risk, consult the technical characteristics of the device before finalizing the purchase.

  1. An SSD can be better than an HD

SSDs do not record information on a magnetic disk, using part of the RAM or other components of the computer. Its boot performance is better, but its space is reduced and its price is more expensive.

To get an idea, Kingston’s SSDNow V310 has 960 GB and costs at least $ 2799, which is equivalent to the computer price. For less than half the value, you buy a 1 TB hard disk. This type of device is only recommended for those who want good performance besides storing memory.

  1. Look for devices with physical encryption

Having a password in the HD software is important, but a lock button on the device is safer for your documents. The device firmware may be corrupted by viruses from other computers. In case of storing sensitive data, all care is little. So pay attention to the safety details when buying a component of these.

  1. Worry about digital and virus encryption

Do not forget to take care of the security of your hardware. Use the HD on the PC always with the antivirus activated, to avoid invasions that contaminate the two equipments.

  1. Do not heat the external hard disk and take care of it.

The same care you take with your PC or notebook will apply to the external hard disk. Be aware that the environment is not too hot to compromise its operation. If possible, leave it in a cool place.

Clean the appliance whenever possible without using water or substances that cause problems in the circuit. Avoiding dust buildup also helps maintain good performance.

  1. If your space requirement is large, look for dual HDDs

Some companies offer HDDs with 8TB of storage capacity by attaching two HDDs. Such a model comes out for around R $ 1,800. It’s a good investment, better than buying two 4 TB per thousand reais each.

  1. If you do not want to spend money on an equipment, you can use the cloud

Before buying anything, assess whether there is a need to have a physical HD. Dropbox offers 500GB storage for $ 499 per year. Other competing services offer similar packages, such as Amazon’s Cloud disk.

The main drawbacks of having an HD is that this is a hardware susceptible to physical damage, which can corrupt your memory forever. It needs to be stored in a place where it does not accumulate heat or dirt, for its correct functioning.

The cloud does not depend on physical boundaries, but is prone to invasions. So if you’ve chosen to store files on the Internet, know that it’s not a safe environment, especially after the revelations of American espionage in 2013. In the case of HDs, security is greater, but it brings greater care to physical equipment. Evaluate your user profile, your needs, the pros and cons and make your investment without fear.
