Read on and learn the six steps to choosing the right external hard drive for you.
6 Steps To Choosing An External Drive. That Special Companion For Your Mac
I am guessing you love your Mac, whatever flavor it is, iMac to MacBook to MacBook Air and why not?
They are lovely machines, designed to be easy to use, and get along with but they are not particularly expandable.
Your Macs attractive design,
Thinner, smaller, lighter enclosures. Is exactly what you wanted. And what about the software programs you have on it.
Well they are not growing smaller neither will there be less of them over time.
The best selfies, HD video’s, the wish to have documents with embedded pictures and video’s not to mention most documentation is being provided on-line and you need to store your own copy … course you do.
Macs are designed to be … well a Mac
so you won’t want to open up the back (you can’t on some Macs) and dig around in the internals to upgrade the hard drive …
And god forbid the next software upgrade makes your Mac unusable, or the internal disks you have everything so carefully stored on fails … so what do you do?
You need options and alternatives.
Storing your data in the cloud is a good option, assuming you have the network bandwidth to get to it all should you have a failure.
But what if what you have stored is sensitive, pictures, company documents. Would you be concerned about anything up in the cloud should someone break in and get to it?
And there you have it, the argument to get yourself an external hard drive and depending on how crucial your data is then maybe two.
It’s unfortunate, that consumer grade hard drives both internal and external have been known to fail, so if you really have got to have it, have it in several places and you won’t be left crying or cursing that it’s gone.
An external drive that is easy to use, that you can store away when you’re not using it, or transport files between locations.
And now there are so many options in the way your little Mac companion drive looks, how handy it is to take with you and how much you can get on it. Now we get to the meat, the how, the process,
The 6 Steps To Choosing Your External Drive
1. What Mac Do You Have?
This is important because an older Mac may have a USB 2.0 interface. What’s that?
The place you plug your external drive into.
The newest Macs will have thunderbolt connections. Wha?
It means that you have a much faster connection interface to your Mac.
A USB 2.0 port compared to a Thunderbolt port is a physically different connection. You may only need an cable adaptor or a compatible cable but it’s worth checking.
If you have several Macs types and generations then you may be looking for something able to connect to them all.
What interfaces to they have? make a note.
2. Next, Have A think About Your Main Reason For Having An External Drive
Is it storage for those mega important files or
for saving games, apps and movies that can be downloaded again easily.
Are they work files? Customer files? Sensitive? Do you need a drive that supports password protection and encryption?
Are you planning to share your drive between a Mac and a PC? Then you need to make sure it is of a large enough capacity to store the files you want to share and you’ll need to spend the short time needed to format the drive to ExFAT or have a ExFAT partition where you can interchange files.
Are you out and about on location? Are the sites you visit hard drive unfriendly? Dust, dirt and water can kill of your external drive super quick. Could it get knocked about? Then a ruggedized or a solid state hard drive may be just what you need.
Are your files large and numerous? HD video’s, photographs so you need a drive with capacity and one that is quick.
3. Storage Capacity In Relation To Price
It’s a universal truth that the larger the storage capacity, the higher the price.
If your external drive will be backing up several Macs then you’ll need to tot up the storage capacity of them all and how many days/weeks of backup you want to store.
There is nothing wrong with taking a leaf out of the book of large corporates. They will have hard drives that does Monday’s backup and use a different set for Tuesday’s backup, alternating days in the week. So that if the worst happens they have options.
Is a 1 TB disk drive or a larger 4 TB+ needed?
If your total backup requirement is 2TB then it is best to get a hard drive that is at least that size for backup. You probably should really have a 3TB or larger hard drive so that you can store your backups and grow into the drive.
Could you consider 2 x 2 TB’s spreading the backup file load and have alternating backup drives?
Ok so your armed with that knowledge what now?
Compare your favored hard drives against the storage capacity you have in mind.
4. Connectivity And Speed
External hard drives for Macs usually have USB 3.1 or 3.0 interface with backwards compatibility with USB 2.0 interface for using with older Mac models.
That’s how you physically connect. What else?
A number of external hard drives now take their power from the USB port on the Mac itself. This has implications for older Macs.
Macs are very picky about how much power external devices take and not all manufacturers have stuck as strictly to the USB 2.0 specification as Apple Inc. You may find those drives won’t power up at all or consistently on your Macs USB 2.0 port so check.
Check that other users haven’t experienced that problem.
you many not want a physical connection to the hard drive at all. You may want to perform backups wirelessly and automatically over Wi-Fi. In that case you’ll be looking at a network connected device.
You may also want a drive that can be connected to and perhaps shared with your other household devices, such as to your game consoles, iPhones, printer, Windows based machines or even to your router.
In that case you’ll need to check your drive of choice is compatible with all those devices, get a hard drive that is big enough, partition it up and your good to go.
But if you’re looking at a drive for a professional application, or to connect to multiple devices across Wi-Fi then it pays to look for a drive speed that is up to that.
5. Reliability And Manufacturer Reputation And Warranty
The reliability of hard drives is generally determined by the manufacturer’s reputation for quality products, and on the length of the warranty offered. Why?
Let’s face it a manufacturer is not going to offer a long warranty on hard drives that fail often.
Stick with the best manufacturing brands if you can, even if it costs a bit more. You’ve not been shy to spend on your Mac so it pays to make sure its external hard drive companion is of suitable quality.
For drives aimed at a consumer, the best warranty you’ll see in the market place is a three year warranty offered by top manufacturers of the premium solid state drives and mechanical drives. A 2 year warranty is considered pretty good.
6. Handsome Looks And Portability
You have a Mac, you’ll want something that looks good beside it right?
It’s no accident that the best external hard drives for Macs have attractive designs as manufacturers that cater to the Mac market know well that a buyer of a Mac likes his kit to look good.
As for transporting your hard drive around,
size and weight in relation to disk capacity is important. Check that the dimensions and lightness of the drive suits your purpose.
Desktop external hard drives designed for use in the home are heavier and the technology assumes a stable surface.
Laptop class drives – as many of the portable external hard drives are. Are largely aimed at the portable market place due to their smaller internals.
Some resist shocks to the drive and drops to a certain extent.
If you are looking at taking your hard drive around with you it will pay to get a quality case for it. And look for a drive with features that make it more tolerant of what might happen to your drive in your pocket or bag.
About Paul Gregory
I’ve been a system administrator for various corporates for 15 years. And as admin I’ve helped many with their Mac’s and there many Apple devices.
I’m excited by watching users, armed with a little knowledge take control of their Mac’s and their files. And why not?
When I’m not at work or working on the site I like to chill with few beers. And watch a bit of car racing. From Formula 1 to stock car racing. The competition is my thing.
