Now compared to a similarly spec'd external hard drive, you tin can get the same storage capabilities for under $150. This particular difficult drive is the Lacie Rugged Mini 2TB external drive. It'due south one of my absolute favourites!
External Hard Drives Can Be Used Beyond Multiple Devices
Admittedly, internal storage is nice since information technology reduces the risk of losing files from an accidentally damaged external drive. Internal storage also takes away that 1 actress thing you'd demand to carry effectually with an external drive.
However, External hard drives tin have storage saved from one estimator, so exist easily accessed from another computer. All yous accept to do is plug it in! This makes life quick and like shooting fish in a barrel when trying to transfer large files to some other computer or person.
I'll permit you exist the approximate if that extra $thousand for internal storage is necessary or not.
Why You Should Get An External Hard Drive
Having an external hard bulldoze makes life a whole lot easier when information technology comes to media direction. Whether you want to take a defended "Travel Drive" for bankroll up vacation photos, or one that never leaves your computers side. There are several reasons why an external hard drive might be worth purchasing. Here'south why I use external hard drives:
- I have several drives that never get out my desk-bound. Their sole purpose is to back up the files and expand the overall retentiveness I have access to on my computer.
- I take 1 2TB(2000GB) SSD Drive(Explained Below) that I use every bit a "Travel Drive". This bulldoze is to dump media on when I am on the road or have to pass off/receive project files and media.
Without my external drives, I would quickly run out of room on my calculator, accept no rubber place to back upward my media, and would struggle with information direction. I'grand sure y'all already know how much space a few photos and videos can take up!
Types Of External Hard Drives
When shopping for external hard drives you will be faced with two options, HDD or SSD.
Difficult-Deejay Drives(HDD): Hard-Deejay Drives aka HDD drives are the cheapest type of difficult drive y'all can buy. They incorporate a physical disk inside that holds all of your information. Compared to solid-country drives they are noticeably slower but are very affordable. An HDD drive is best left in a permanent spot in your habitation where it won't get moved effectually very often. With such delicate components inside, traveling with HDD drives tin be risky equally they can be easily damaged by bumps in transit.
Solid-State Drives(SSD): Solid-Country Drives aka SSD drives are drives that have no moving office inside them. There are no spinning disks to scan, or exceptionally fragile components inside them. A key point to know nigh SSD drives is that they are extremely fast, but extremely expensive compared to their Hard-Disk Drive counterpart. If yous accept the ways, SSD drives are the best selection for external memory and handle extremely well while traveling.
Information technology is important to note that both SSD and HDD drives are delicate to different degrees and should be handled with intendance while traveling regardless . Certain brands of difficult drives offer "Rugged" drives with a beefier outside to keep the interior components and storage safety.
How Much External Hard Drive Storage You Need
Difficult drives come in everything from equally low equally 64GB all the way to several hundred terabytes. The struggle is only trying to detect what corporeality best suits your needs. The outset question y'all should ask yourself is, "what types of files volition I be storing on this external hard bulldoze?".
If y'all are needing one more for leisure, to backup a few documents, personal photos, and video, you don't need much more than 250GB of storage. All the same, if you lot have the money, going with more storage never hurt anyone.
If y'all are similar me, using your bulldoze strictly for photography work, a 1TB or 2TB drive volition suffice for quite some time. Simply make certain you lot routinely clean out actress unwanted images every once in a while.
If you are dealing with mostly video, specially in 4K, you lot should be looking at a 2TB to 4TB drive at the very minimum. Trust me when I say yous volition fill up that space faster than yous can imagine.
If y'all are needing more than storage space than what singular external hard drives offer, you should consider a RAID setup. Long story short, a RAID is a series of hard drives merged together to create 1 giant hard bulldoze that has incredibly fast transfer speeds, automatically backs upwards your files, and can exist sending information to multiple computers at one time through a server. How amazing does that audio?

Unfortunately RAIDs are several thousand dollars at the least. For today, we are just sticking with more affordable storage devices, just now yous know a flake about RAIDS!
Because External Difficult Drive Speeds
This may be the nigh important piece to consider, how fast is the drive you lot are getting? You could have a 3TB hard drive but if it has a low max RPM or an older model of USB or Thunderbolt, information technology will simply be slowing you down. Here are the things to consider for bulldoze speeds:
Connectors: What cable connects your drive to your estimator? There is actually a massive departure betwixt different types of cables. The main cables you will come across in new external drives are USB 2.0 and 3.0, and Thunderbolt ane or ii.
USB 2.0 has a maximum transfer speed of 480Mb Per Second while USB 3.0 has a maximum transfer speed of 5GB Per Second. Thunderbolt 1 and two both take a max transfer speed of 40GB Per Second! However, Thunderbolt ii has a bidirectional transfer speed of 20GB Per 2nd while the Thunderbolt 1'southward bidirectional speed is just 10GB Per Second. Ironic to say only 10GB per second isn't information technology?
Drive RPM:Depending on the drive, some can process incoming and outgoing data faster than others. If you are dealing with photos in bulk or high resolution video, I would recommend a drive within the 5400rpm – 7200rpm range. If yous are strictly using the external drive for documents and other small files, the bulldoze RPM shouldn't be much of a concern to you.
Also notation the operation you become out of your drive will also come up downwards to the capabilities of your calculator.
Considering The Value Of An External Hard Drive
Purchasing an external hard bulldoze is an investment. It tin can exist a lot of money upwardly front, only for the corporeality of storage solutions they offer, it'southward definitely worth while. When you start hunting for hard drives you'll detect it becomes challenging to tell which one offers the most 'blindside for your buck'.
Here'due south a great calculation you can do to decide the value of a difficult drive:
Separate the toll by the total storage to equal the price per GB.
For the 2TB Lacie external hard drive shown previously, it costs $128 and has 2000GB of storage. That means that $128 / 2000GB= $0.06 per Gigabyte. You lot tin do this same formula to compare multiple hard drives and find out which offers the best value for the money.
With that being said, always remember to do your research on different brands and external hard drives. Some may be more prone to declining than others, and so it's wise to do your inquiry before purchasing.
Last Thoughts
At that place's cipher worse than trying to relieve a file only to realize your computer is out of space. With an external hard bulldoze, you'll never take to worry; especially if y'all get 1TB or more!
Buying a expert hard drive may seem like a big investment. Just only think… it's a heck of a lot cheaper than trying to recover lost files from a crashed computer. Whether you are simply looking for more than infinite, or backup the files yous already have, external hard drives have you covered.
Hopefully this helps y'all to make a more informed decision on finding the perfect dwelling house for your media files! Practise yous have a favourite hard bulldoze or brands you lot stay away from? Let me know in the comments!
