Best External Hard Drives 2026: Portable and Desktop Picks for Every Budget

Q: Can I use an external hard drive for my NAS?

Yes. Many data hoarders 'shuck' external drives (remove the internal drive from the enclosure) to use in NAS arrays. WD Elements and Easystore externals often contain WD Red or Ultrastar drives inside. Check warranty implications before shucking.

External drives are the category where the sticker price lies to you most. A portable drive and a desktop unit can look similarly priced on the shelf and be twice as far apart per terabyte, and the cheapest desktop units are often the same drives you would buy bare, wrapped in plastic and sold for less. So here’s what the price per TB actually says to buy in 2026.

The Quick Answer

In a rush? Here’s the cheat sheet:

Best overall (desktop): WD Elements Desktop (12-18TB), best price per TB in an external, reliable WD drive inside
Best portable: WD My Passport (5TB), compact, bus-powered, solid build
Best for shucking: WD Easystore (14-18TB), often contains WD Red or Ultrastar drives, frequent sales
Best premium portable: Samsung T9 Portable SSD (4TB), if you need speed and can afford the premium
Best budget: Seagate Expansion Desktop (8-12TB), cheap, functional, gets the job done

Desktop vs Portable: Which Do You Need?

This is the first decision and it shapes everything else.

Desktop External Drives (3.5” with power adapter)

These are the big boys. They sit on your desk, plug into the wall, and hold a standard 3.5” hard drive inside. The advantages:

Much better price per TB: about $35/TB at the 25th percentile against $57/TB for portables, measured 11 August 2026
Higher capacities: 8TB to 22TB in a single unit
Better thermals: more airflow, the drive runs cooler and lasts longer
Shuckable: you can pull the drive out and put it in a NAS

The downside is obvious: they’re not portable. They need wall power and they weigh 1-2 pounds. If this lives on your desk as a backup or media drive, desktop is the way to go.

Portable External Drives (2.5” bus-powered)

These are the ones you throw in a bag. Powered by USB, no wall adapter needed. The trade-offs:

Max capacity around 5TB: 2.5” platters can only hold so much
Higher price per TB: you’re paying for the portability
More fragile: smaller platters and bus power mean these are more sensitive to drops and bumps
Not great for shucking: the drives inside are 2.5” laptop drives, not useful for NAS builds

If you need storage you can carry, portable is the move. Just don’t expect the same value per TB.

My Specific Recommendations

Best Desktop External: WD Elements Desktop (12-18TB)

This is what I recommend to anyone who asks “what external drive should I buy?” The WD Elements Desktop is as simple as it gets: a WD drive in a plain black enclosure with USB 3.0. No flashy software, no unnecessary features.

Why I recommend it:

The cheapest Elements Desktop listings sit around $34/TB today. This page used to say $11-13/TB on sale, which was true of an earlier market and is not true now
Contains WD White Label drives (CMR, same platters as WD Red)
USB 3.0 with up to ~180 MB/s transfer speeds
3-year warranty

The 14TB and 16TB models hit the sweet spot for price per TB. I track these daily on HDDHunt and the best deals surface automatically.

Best for Shucking: WD Easystore (14-18TB)

If you’re planning to pull the drive out and put it in a NAS or server, the Easystore is your target. These are Best Buy exclusives in the US and frequently go on sale during holidays.

What’s inside: Depending on the batch, you’ll find WD Red Plus, WD White Label, or occasionally WD Ultrastar drives. All CMR, all solid for NAS use. This is why these units are the most commonly shucked drive on r/DataHoarder.

The shucking consideration: Removing the drive from the enclosure technically voids the external warranty, though the internal drive still has its own WD warranty in many cases. If you’re comfortable with that trade-off, shucking is the cheapest way to fill NAS bays. For more on NAS drives, check my best drives for NAS guide.

Best Portable: WD My Passport (5TB)

The My Passport has been my go-to portable recommendation for years. The 5TB model is the sweet spot. It’s the highest capacity available in a 2.5” bus-powered form factor from WD.

Why it works:

5TB in a pocket-sized form factor
USB 3.0, bus-powered (no wall adapter)
Hardware encryption option
Reasonably durable for a bare portable drive, though none of these are rated for drops

Portables run about $57/TB at the 25th percentile and $68/TB at the median today, against roughly $35/TB for a desktop unit. You are paying a premium of about 60% for the drive to fit in a bag, which is a bigger trade than it used to be.

Best Budget: Seagate Expansion Desktop (8-12TB)

If you want the most storage for the least money in an enclosure, the Seagate Expansion Desktop is still the sensible default. The best price per terabyte of any external I track today is the 16 TB Expansion at $482.13, which is $30.13/TB. This page used to say these regularly hit $11-12/TB. They do not, and have not for some time.

The caveat: Seagate has used SMR drives in some Expansion models, particularly at lower capacities (2-8TB). For a backup drive this isn’t a problem. You’re doing sequential writes. But I wouldn’t shuck these for a NAS. Read my CMR vs SMR guide if you’re unsure why that matters.

What About External SSDs?

External SSDs are fantastic, but they’re still 2-3x more expensive per TB than external HDDs. The Samsung T7 and T9 series are excellent if you need the speed (1,000-2,000 MB/s vs ~180 MB/s for USB HDDs) or the durability (no moving parts = survives drops better).

For working files you actively edit (video projects, game libraries, development environments), an external SSD makes sense. For backups, media storage, and archival? Stick with HDDs. Check our SSD vs HDD price comparison for the current numbers.

How I’d Spend Different Budgets

These are measured against live listings on 11 August 2026, taking the largest real external desktop drive available inside each budget.

Budget	Best capacity available	$/TB
$100	2 TB	$49.99
$200	4 TB	$47.00
$300	8 TB	$32.50
$500	16 TB	$30.13

An earlier version of this table said $100 bought 8 TB and $500 bought 36 TB. Both were true once and neither is true now, so the table has been rebuilt from measured prices rather than left to age. The shape of it is the real advice: price per terabyte improves sharply as you go up, so the biggest single drive your budget reaches is almost always the right buy.

One thing that has changed enough to reverse an old recommendation: shucking mostly does not pay any more. At seven of the nine capacities I track, buying the bare internal drive is cheaper than buying the external and opening it. The numbers are in the piece on what a cheap drive costs you later.

Tips Before You Buy

Check HDDHunt first. I track prices across Amazon daily. The best deals page will show you if there’s a sale running.
Don’t buy below 8TB for desktop externals. The price per TB is terrible at 4-6TB. Jump to 8TB minimum.
Consider shucking. If you have a NAS, buying externals on sale and shucking them is often cheaper than buying bare internal drives.
Always keep two copies. An external drive is a great backup target, but it shouldn’t be your only copy of anything important.
Format for your use case. ExFAT works across Windows and Mac. NTFS for Windows-only. APFS/HFS+ for Mac-only.

Frequently Asked Questions

What is the best external hard drive in 2026?

For most people, the WD Elements Desktop (12-18TB) offers the best price per TB. For portability, the WD My Passport (5TB) is the best balance of capacity and size. Check HDDHunt for live pricing updated daily.

Are external hard drives still worth buying in 2026?

Absolutely. External HDDs still offer 2-3x better price per TB than external SSDs for bulk storage. If you need 4TB+ of portable or backup storage, an external HDD is the most cost-effective option.

Can I use an external hard drive for my NAS?

Yes. Many data hoarders “shuck” external drives (remove the internal drive from the enclosure) to use in NAS arrays. WD Elements and Easystore externals often contain WD Red or Ultrastar drives inside. Check warranty implications before shucking.

How long do external hard drives last?

Most external HDDs last 3-5 years with regular use. Desktop models with external power tend to outlast bus-powered portable drives. Always keep backups. No drive lasts forever.

Should I buy an external SSD or external HDD?

It depends on your use case. External SSDs are faster, lighter, and more shock-resistant, great for active working files. External HDDs are much cheaper per TB, better for backups, media libraries, and archival. For a detailed comparison, read our SSD vs HDD price per TB guide.
