Portable external drives are growing in capacity which makes them an ideal solution for those users who move around a lot and need large amounts of storage space. Typically they are 2.5” drives of the laptop variety and what makes them convenient is that they are powered via the computer’s USB port, so unlike desktop external hard drives no external power supply is required.
There can sometimes be a power issue if a lot of devices are connected to the computer but in most instances this is not a problem. They are easy to transport around and most are small enough to fit into your pocket. And because you are most likely to use these drives on different computers at various locations they have a straight forward plug and play setup.
Depending on the model there are USB2.0, USB3.0 and Firewire interfaces available for more connectivity options. If security is an issue due to portability and the possibility of losing the drive, something like the Seagate Freeagent Go offers 256bit AES encryption as protection. Alternatively if you are looking for a drive that’s durable and may take some knocks then the Freecom Toughdrive may well fit the bill.
Portable external hard drives make carrying around your important files, photos and documents so easy and convenient. They are extremely light and durable, and with data encryption, safe if you happen to lose them. With capacities now of 1TB, you have an incredbly large amount of storage space for even the most demanding of users.
External USB hard drive
External hard drives,, connected to PCs or Macs,, have become increasingly popular. There are five major types of external hard drives: enterprise-class desktop drives, regular desktop drives, laptop-class portable drives, slim laptop-class portable drives, and flash drives. Also called mirroring, RAID 1 requires at least two internal drives. Storage capacity in external HDDs can range from about 2GB to 4TB. More and more people are archiving huge amounts of data, sometimes gigabytes (GBs) at a time, to optimize their daily work routine.
- The first two use 3.5″ hard drive mechanisms and are effectively non-portable: they sit on your desk, depend on wall power, and aren’t easy to carry in typical bags.
- In this setup, data writes identically to both drives simultaneously, resulting in a mirrored set.
- In fact, some drive companies put two 4TB drives in one chassis, creating an 8TB HDD, which is total overkill for most people.
- Hundreds of thousands of MP3s or graphics, or hundreds of DVD-size movies, may be stored on a single and very affordable 1-terabyte (TB) external hard drive.
- Flash drives are keychain-sized but relatively limited in capacity and crazy expensive when they begin to approach laptop drive capacities.
What’s more, a RAID 1 setup continues to operate safely even if only one drive is functioning (thus allowing you to replace a failed drive on the fly). The drawback of RAID 1 is that no matter how many drives you use, you get the capacity of only one. For reference, computers these days usually come with anywhere between about 250GB and 750GB of space in the hard drive. Get some kind of automatic backup. Much larger than a USB flash drive, yet still small enough to fit inside your coat pocket, portable hard drives offer an excellent middle ground for those who want to combine large amounts of storage with the flexibility of a flash drive. RAID 1 also suffers from slower writing speeds.
Whether you want a mini external HDD (also known as a flash drive) that you can pin to your keychain and store a few important documents on, or a considerably larger one where you can keep all of your photos, songs, and videos, the possibilities are almost endless. Buying an external or portable hard drive to back up your data is a great first step, but it will be worthless if you don’t remember to actually use it. In most cases they do not require an external power source. Everyone has a horror story about a drive from Company X or Company Y going south on them, along with a warning to steer clear of everything with a particular brand name on it. Many new computer hardware components and computer accessories are plug-n-play, meaning you plug them in and start using them immediately.
Having automatic backup software will take the burden off you and make sure it gets done. Most portable hard drives are compatible with either Mac or PC, so it is important to check requirements before choosing. But the truth is all drives fail at some point, no matter who makes them. Other hardware may require you to install a driver. I do suggest regularly checking to ensure that the auto backup is working, especially at first. Certain devices can be re-formatted but this process can be complicated, so it’s best to get it right from the offset. Your primary concerns should be the size of the actual drive and the warranty period. 500GB and 1TB drives have been around for a long time and are well proven. If you want a faster motherboard, better sound card, an extra computer fan or a new Blu-ray drive, you can easily do the installation yourself.
External hard drive – Trouble shooting
Do you constantly lose important data on your hard drive? Are you seeking help to restore hard drive data back into your computer? Then worry no more as this article will help you on how to restore hard drive data in your PC. This information will give you tips on how to diagnose the problem of losing important documents, files, and stored data in your desktop computer.
Confirm the Source of the Problem
First of all, you need to diagnose whether the hard drive is the ultimate source of the problem. Most of the time, people might only have controller problems that is why they cannot locate their hard drive data. When you experience a mere controller problem, then you must be able to physically remove the hard drive from your computer. The next thing you need to do is to test this hard drive within another computer. If it works, then you have a problem with your computer. If it does not, then clearly, you will have to restore hard drive data.
Avoid Overwriting Data
As much as possible, you do not want to overwrite your data to avoid permanent data loss. The trick is to refrain from adding more data into the hard drive. To illustrate, imagine yourself erasing all your files on the recycle. Once you’ve realized the faulty action, never attempt again to save other files into your hard drive. This is because the new data will overwrite the lost file and this action may be permanent and irretrievable.
