Why the offline copy is the one that survives

Ransomware doesn't care how many copies of your photos you've got. It cares how many of them it can reach. If your backup drive is plugged into the laptop when the encryption starts, or your backup is a folder that syncs to the cloud every few minutes, the malware usually gets the originals and the backup in the same sitting, and you find out when every file has a strange new extension and there's a note on the desktop asking for crypto. The Australian Cyber Security Centre lists regular backups in its Essential Eight for exactly this reason, and the part people skip is that the backup has to be disconnected to count.

That's why a plain external hard drive still earns its place in 2026. It's the one piece of storage in the house that can sit in a drawer with no power, no network and no login, so nothing on the internet can touch it. Cloud sync is handy and I use it, but sync is a mirror rather than a backup: delete or encrypt a file on the laptop and the change flows up to the cloud copy within minutes. A drive you plug in on Sunday night, back up to, eject and put away is boring, and being boring is exactly why it works.

Most of the drives that come into the shop for data recovery aren't backups at all. They're the only copy, usually a portable that got used as extra space when the laptop filled up, and the family photos were moved onto it rather than copied. When that drive gets knocked off a desk there's no second copy to fall back on. All eight drives below were picked to be the second copy, not the first, and every one of them does that job well enough that the choice mostly comes down to capacity and whether you want a password on it.

The 3-2-1 rule without the jargon

You'll see 3-2-1 quoted on every backup page, and it's sound advice once you strip the IT language off it. It means keeping three copies of anything you'd be upset to lose, on at least two different kinds of storage so one failure can't take out both, with one copy kept away from the house so a fire, a flood or a break-in doesn't get everything on the same night.

For most households that looks like this: the working copy on the laptop or desktop, a portable drive that gets a backup every week or so and lives unplugged in a drawer, and a third copy somewhere else. That third copy can be a second drive at a parent's place or the office, swapped every month or two, or a cloud backup service with version history. Two portable drives rotated between home and somewhere else is the simplest version I know of, and it's why one of the picks here makes sense to buy as a pair.

If you've got a lot of machines, or you want backups to happen without anyone remembering, a home NAS with snapshots is the next step up. It doesn't replace the unplugged drive, though. A NAS is still on the network, and it can still be reached by something that's already on your network, so I'd keep a portable drive that spends most of its life switched off even if you run one. The NAS handles the daily convenience, and the drive in the drawer is the insurance policy that nothing on the network can reach.

SMR, and why a 4TB portable slows down halfway through a backup

Here's the bit most listings leave out. Hard drives write data in tracks, and to fit 4TB into a drive about the size of a phone, manufacturers overlap those tracks slightly, a bit like roof shingles. It's called shingled magnetic recording, or SMR. None of the listings below state their recording method, but in my experience pretty much every pocket-sized portable at 4TB and above uses SMR, because that's how the capacity gets in there.

SMR is fine for reading and fine for most writing. Where it bites is a long, sustained write, like the first full backup of a laptop. The drive has a small fast area it writes into first, and once that fills it has to rewrite overlapping tracks as it goes, so the transfer rate can drop sharply partway through. People see a copy that started at over 100 MB/s crawl to a fraction of that and assume the drive's faulty. Usually it isn't, it's just catching up, and it'll get there if you leave it alone.

The practical upshot is to do the first backup overnight, plugged straight into the computer rather than through a bus-powered USB-C hub, and let it finish. After that, incremental backups only write what's changed, which is usually small enough that SMR rarely shows up at all. A 4TB drive at a realistic 100 to 130 MB/s takes somewhere around eight and a half to eleven hours to fill from empty, so don't start it at 10pm and expect to unplug it for school at 7am.

If you need speed rather than capacity, for video editing or a drive that gets written to all day, a portable SSD is the better tool, and I've compared the Samsung T7 Shield and T9 separately. For a backup that gets written once a week and read hopefully never, spinning drives still give you the most terabytes for the money by a long way.

Why every pick here is a portable drive

Desktop external drives use a full-size 3.5-inch mechanism, run off a mains power brick, and generally give you more capacity for the money. I looked for them in this price band and couldn't find enough stocked by Amazon AU or an Australian storefront to recommend, so all eight picks are pocket-sized portables that run off the USB port. For a backup drive that lives in a drawer, I don't think that's a bad outcome.

A portable has one cable and no brick, so there's one less thing to lose and one less plug pack to fail. It's small enough to take to a second location for the offsite copy without thinking about it, and the smaller mechanisms are built to put up with a bit more movement than a desktop drive, although 'put up with' is doing a lot of work in that sentence. There's more on drops in the bench section further down.

The trade-off is power. A portable draws everything it needs from the USB port, and on an older laptop, a front-panel port on a desktop or an unpowered hub, that can be marginal. The symptom is a drive that clicks, spins up and down, or disconnects halfway through a copy. Before you assume the drive's dying, try a rear port on the desktop or a different cable. Nine times out of ten that's the fix, and it costs nothing to try. The other common culprit is a thin, long or worn cable, which drops just enough voltage over its length to leave a portable drive short of power when it spins up.

Passwords, encryption and the recovery trap

Two of the picks, the Seagate One Touch 1TB and the WD My Passport, advertise password protection, and both list hardware encryption, the My Passport with 256-bit AES. For a drive that holds tax records, scanned ID and every photo you own, and that sometimes travels to a second house, that's worth having. If the drive gets lost or pinched, a password-locked drive is a brick to whoever ends up with it.

The catch is on the recovery side, and it's one I'd want explained to me before I bought. On a lot of current portables the USB socket is soldered straight onto the drive's own circuit board, and on hardware-encrypted models the encryption is handled by that same board. If the board dies, or the USB socket gets snapped off, you can't simply pull the drive out and read it in a dock. Recovery is still often possible, but it means board-level work plus the original password, and it costs more than recovering a plain drive.

So if you turn the password on, write it down somewhere that isn't the drive, and don't treat encryption as a substitute for a second copy. A forgotten password on an encrypted drive is about the hardest recovery there is, and sometimes it can't be done at all. If you'd rather not have any of that to manage, the Toshibas are plain drives with nothing to forget. The external drive recovery guide goes through the common failures one at a time if you want the detail.

How much space you actually need

Start with how much is on the computer now, not how big its SSD is. In my experience most household laptops carry somewhere between 100GB and 400GB of real data, and a fair chunk of that is apps you'd reinstall anyway. A 4TB drive covers that many times over, which matters because decent backup software keeps older versions of files, and those older versions are what save you when ransomware or a bad edit quietly overwrote the current copy a few weeks ago.

For one computer, 4TB is plenty for years of versioned backups. For a family with two or three laptops backing up to the same drive, or anyone with a big photo or video library, a 4TB drive gives you headroom, from $269 for the Canvio Advance to $279 for the Seagate One Touch or WD My Passport. I'd lean towards 4TB in this band, because backups only ever grow and the bigger drives cost less per terabyte. The one 2TB pick here, the Canvio Flex, is for a single laptop with a small library or a USB-C-only machine.

On Windows, File History or a scheduled image backup does the job. On a Mac, Time Machine wants the drive formatted its own way, so expect to reformat whichever drive you pick and don't store anything on it first. Either way, set it up so the drive is only connected while the backup runs, then eject it properly and put it away. Most backup tools will nag you when a week goes by without a backup, and I'd leave that reminder switched on, because the weeks slip past faster than anyone expects and the drawer drive is only as current as its last run.

How to make a backup drive last

The biggest killer of portable drives is movement while they're spinning. Unplug a drive mid-copy and knock it on the way, or leave it balanced on a laptop lid that gets closed, and the read heads can touch the platters. After that you'll usually hear clicking, and every extra minute powered on can do more damage. If a drive starts clicking, stop, unplug it and don't keep retrying. That one decision makes more difference to what's recoverable than anything else you can do.

Past that it's mostly common sense. Eject before unplugging so the drive can finish writing and park its heads. Keep it somewhere dry and out of a hot car. Use the cable it came with or a good replacement, because a loose or worn cable causes more 'the drive's dead' panic than actual dead drives do. And test a restore every few months by opening a handful of files from the backup, since a backup you've never restored from is really just a hope.

I'd plan on replacing a backup drive every four or five years, or sooner if your backup software or a SMART health check starts reporting reallocated sectors. Drives rarely die without any warning, but the warnings are easy to miss when nobody's looking. If you're not sure what a drive's health readout is telling you, bring it to our computer repair workshop on the Central Coast and I'll read it for you before anything goes wrong.

Side-by-side comparison

What we see fail at the bench: external hard drives

External drives come in for recovery far more often than for repair, because by the time anyone brings one in, the drive itself matters less than what was on it. The failures fall into three groups, and they're consistent enough that you can buy and use a drive to avoid most of them. None of them are rare, and all three are far less painful when the drive in question was a backup rather than the only copy.

Decision tree: which one should you actually buy?

• One drive for a single laptop's weekly backup? → The Toshiba Canvio Advance V10 4TB at $269, a top-15 seller here and sold by Amazon AU. Plain, simple and easy to recover.
• Setting up a proper rotation with an offsite copy? → Two Toshiba Canvio Flex 2TB drives at $229 each, if your backup fits in 2TB. Keep one at home and one elsewhere, and swap them every month or so.
• Carrying client or tax records between home and work? → The Seagate One Touch 1TB at $219 for its hardware encryption. Write the password down somewhere safe.
• Replacing an old My Passport and happy with your routine? → The WD My Passport 4TB at $279 keeps your existing tools and habits, with password protection.
• Several laptops or a big photo library on one drive? → The Seagate One Touch 4TB at $279, which lists Rescue Data Recovery Services. The Canvio Advance 4TB at $269 is the lowest-priced way to get the same space.
• Drive clicking, not showing up, or socket broken? → Stop powering it on and bring it to our Erina workshop. I'll tell you what's failed and what recovery would involve before anything is opened.

Frequently asked questions

Is an external hard drive enough protection against ransomware?

On its own, only if it's unplugged when the attack happens. Ransomware encrypts whatever it can reach, which includes any drive that's connected at the time and any cloud folder that syncs automatically. A drive you connect for the backup, eject afterwards and store away is out of reach for the rest of the week. Pair it with backup software that keeps older versions of files, so if something nasty slips into a backup before you notice, you can still restore from an earlier point. For most households that combination of an unplugged drive and versioned backups is the most useful protection you can buy.

Should I buy an SSD or a hard drive for backups?

For a weekly backup, a hard drive still gives you far more space for the money. A 4TB portable hard drive costs roughly what a much smaller portable SSD does, and backups only need to be written once a week, so the SSD's speed doesn't buy you much. SSDs make more sense for a drive you work from every day, for video, or for something that gets thrown in a bag constantly, since there are no moving parts to damage in a drop. Plenty of people end up with both: an SSD for daily work and a hard drive for the backup.

What is SMR and should I avoid it?

SMR stands for shingled magnetic recording, a way of overlapping data tracks to fit more capacity into the same space. It slows down during long continuous writes because the drive has to rewrite neighbouring tracks as it goes. For a backup drive that's mostly an annoyance on the first full backup, which can take much longer than expected. After that, incremental backups are small and the slowdown rarely shows. You'd avoid SMR for a NAS array or a drive under constant heavy writing, but for a portable backup at 4TB or more it's close to unavoidable and perfectly usable.

How long do external hard drives last?

In my experience a portable hard drive that's handled gently usually lasts four to six years before it starts showing signs of wear, and plenty go longer. The ones that die young almost always died from a drop, heat or a damaged socket rather than old age. Because you can't predict which drive will fail, the safer approach is to plan on replacing it around the five-year mark, check the drive's SMART health now and then, and always keep a second copy so one failure never costs you anything.

Can you recover data from a dead external hard drive?

Often, yes, but it depends on what failed. A broken cable or a failed USB adapter is usually a simple fix. A drive that clicks after a drop needs clean-room work, which costs a lot more. Encrypted drives and drives with the USB socket built into the main board are harder again, and a forgotten password on a hardware-encrypted drive may be unrecoverable. The best thing you can do the moment a drive misbehaves is stop powering it on, because repeated attempts on a damaged drive usually make things worse.

Do I need to format a new external drive for Mac?

Usually, yes, if you want to use it with Time Machine. Most drives ship formatted for Windows, and some can be read and written by a Mac as they come, but Time Machine wants the drive in Apple's own format. That applies to every drive here in practice. Reformatting takes a minute in Disk Utility, but it erases everything on the drive, so do it before you copy anything on. If you need to move files between a Mac and a Windows PC, that's a different job and better handled by a second drive.
