Best External hard drives 2026: 11 Compared (12 Sources)

What are the best external hard drives in 2026?

Summary

Despite the rise of external SSDs, traditional external hard drives (HDDs) remain by far the most cost-effective way to store and back up large amounts of data in 2026 — and in mid-2026 the gap actually widened back in HDDs' favour. Bulk external HDD storage now runs roughly $30-45 per terabyte at desktop capacities, while the NAND shortage has pushed portable SSDs to roughly $110-150 per terabyte (up from $60-80/TB earlier in 2026), so spinning disk is once again three-to-four times cheaper per terabyte. The best overall portable HDD is the WD My Passport (5TB, ~$209, ~$42/TB), recommended by Wirecutter and PCWorld for its combination of encryption, backup software, and reliability. For bulk desktop storage the Seagate Expansion Desktop (16TB, ~$484) is the value pick at ~$30/TB — the lowest cost per terabyte among drives that are actually in stock. [src1, src2, src3, src12]

The headline change since the last revision is that the Seagate Expansion 28TB — the HAMR drive that held the $/TB crown at ~$290 (~$10/TB) — has vanished from the retail channel. TechRadar checked Amazon, Best Buy, Walmart and Newegg in June 2026 and found it sold out everywhere with no backorder date, and third-party sellers are asking around $1,000. Its buy link has been removed from this card rather than left pointing at an unbuyable listing. The largest Seagate Expansion still in stock is the 24TB (~$722, ~$30/TB). [src10, src11]

The external HDD market in 2026 splits into two product classes that should never be compared on one axis: portable 2.5-inch bus-powered drives (1-6TB, no external power needed, ~$42-70/TB) and desktop 3.5-inch drives (4-24TB, AC adapter required, ~$30-44/TB) that are faster and dramatically cheaper per terabyte. Western Digital and Seagate control nearly the entire market, with Toshiba and LaCie offering niche alternatives for budget and rugged use cases respectively. The dominant story remains supply: HDD prices have surged ~46% since September 2025 per TrendForce data, and WD's CEO confirmed the company is "pretty much sold out for calendar 2026" with enterprise agreements extending into 2028. AI-focused enterprise customers now represent 89% of WD's revenue, with consumer sales at just 5%. Q4 2025 contract prices jumped ~4% QoQ — the sharpest increase in eight quarters — and suppliers warn this pressure will persist through 2026. Consumer pricing and stock remain volatile week to week.

Top 11 Models Compared

Prices are for the exact capacity named in the Model column — capacity is the SKU and $/TB is steeply non-linear, so compare on the $/TB column, not the sticker.

Best for Each Use Case

Best Overall Portable: WD My Passport (5TB, ~$209, ~$42/TB) — Check price

The WD My Passport is Wirecutter's and PCWorld's consensus pick for the best portable external hard drive. It offers 256-bit AES hardware encryption, WD Backup software with ransomware protection, and reliable performance. The 5TB model provides the best capacity-to-price ratio in the portable WD line at ~$42/TB. USB 3.2 Gen 1 over a Micro-B connector delivers up to 120 MB/s sustained reads; the drive is bus-powered, so no wall adapter is needed. Three-year warranty. Note: pricing has risen ~60% since late 2025 due to the AI-driven HDD supply crunch, and the 5TB has been discounted from a $284.99 list. [src1, src2, src8]

Best Value / Lowest $/TB: Seagate Expansion Desktop (16TB, ~$484, ~$30/TB) — Check price

With the 28TB gone from the channel, the 16TB Expansion Desktop is the cheapest cost per terabyte you can actually put in a cart: ~$484 for 16TB works out to ~$30/TB, versus ~$44/TB for the 12TB WD Elements and ~$42-70/TB for every portable on this list. It is a 3.5-inch drive with a USB-A cable and a mandatory AC adapter — not a travel drive. Plug-and-play with no bundled software, and it ships with Rescue Data Recovery Services. Compatible with Windows, macOS, ChromeOS, PlayStation and Xbox. PCWorld measured close to 280 MB/s on this Expansion Desktop family, roughly twice what a 2.5-inch portable manages. [src7, src1, src10]

Most Capacity Still In Stock: Seagate Expansion (24TB, ~$722, ~$30/TB) — Check price

The largest external HDD you can currently buy at a normal retail price. At ~$722 for 24TB (~$30/TB) it matches the 16TB on cost per terabyte while nearly halving the number of enclosures, cables and outlets you need for the same archive. Same USB 3.0 / USB-A interface, same AC adapter requirement, same Rescue Data Recovery Services. Buy this instead of the 16TB only if you genuinely need 24TB in one box — over-spec'ing capacity you will never fill is dead money at these prices. [src7, src1, src10]

Largest Portable HDD Made: WD My Passport Works with USB-C (6TB, ~$335, ~$56/TB) — Check price

The highest-capacity portable HDD on the market at 6TB. While branded "Works with USB-C," it uses a Micro-B connector with an included USB-A to USB-C adapter — the port on the drive is not USB-C. Includes Acronis True Image software and 256-bit AES encryption. The enclosure is made from over 50% post-consumer recycled plastic. At ~$56/TB it is the most expensive per terabyte of the HDDs here, but still roughly a third the price of a 4TB+ portable SSD in 2026's flash market. [src6, src1, src12]

Best Desktop with Security: WD My Book (18TB, ~$570, ~$32/TB) — Check price

Approximately 200 MB/s sequential performance with built-in 256-bit AES hardware encryption and WD Security password protection. Includes WD Backup and Apple Time Machine compatibility. Available up to 22TB. Three-year warranty. Ideal for those who need both large capacity and hardware data security in one box. The 18TB has fallen from ~$755 to ~$570 since June 2026 (a 24% drop against a $754.99 list), which now puts it at ~$32/TB — within rounding distance of the Seagate Expansion drives, so the encryption is close to free. [src2, src4, src8]

No-Frills Desktop: WD Elements Desktop (12TB, ~$530, ~$44/TB) — Check price

Bare-bones desktop storage with no encryption and no bundled backup suite. At ~$44/TB it is now the worst value of the four desktop drives here — the 16TB Seagate holds 4TB more for ~$46 less, and the 18TB My Book adds hardware encryption for ~$40 more. Buy it only if you specifically want a 12TB box. Preformatted NTFS for Windows, reformattable for Mac. USB 3.2 Gen 1 with backward USB 2.0 compatibility. Two-year warranty. The interior typically houses a 5400 RPM drive with 256MB cache. Stock is thin — Amazon showed only 2 units at the time of verification. [src4, src1]

Fastest Portable: Toshiba Canvio Advance (4TB, ~$196, ~$49/TB) — Check price

Outperforms the WD My Passport in raw speed tests at 138 MB/s read and 154 MB/s write. Weighs just 210g with a slim 19mm profile. Includes Toshiba Storage Backup Software and password protection. Available in four colors. At ~$49/TB it is mid-pack on value; buy it for the speed and the 4TB sweet spot rather than the price. [src5, src3]

Best Rugged Portable: LaCie Rugged Mini (5TB, ~$217, ~$44/TB) — Check price

Drop-resistant up to 1.2 meters, rain-resistant, and pressure-resistant up to one ton. The iconic Neil Poulton design with orange rubber bumpers has been an industry standard since 2005. USB 3.0 with up to 130 MB/s transfer speed. Two-year warranty with Rescue Data Recovery Services. Ideal for photographers, videographers, and field workers. Back in stock as of August 2026 at ~$217 — actually cheaper per terabyte than the Seagate One Touch, so the ruggedisation costs nothing over a plain portable. Note this is the Rugged Mini (STJJ5000400, USB 3.0 HDD); the LaCie Rugged USB-C and Rugged SSD Pro are different products at different prices. [src5, src3]

Best Budget: Seagate Portable (2TB, ~$130, ~$65/TB) — Check price

The cheapest live name-brand portable, and now cheaper than the WD Elements Portable 2TB (~$140) — the two swapped places since June 2026. No-frills design with USB 3.0, plug-and-play for both Windows and Mac. Compatible with PlayStation and Xbox for game storage. One-year Rescue Data Recovery Services included. Discounted from a $149.99 list. Note the $/TB penalty: at ~$65/TB you pay more than double the desktop rate for the privilege of bus power and a pocketable size. [src3, src4, src8]

Key Market Trends (Q2-Q3 2026)

• The 28TB Expansion has left the retail channel: TechRadar checked Amazon, Best Buy, Walmart and Newegg in June 2026 and found the Seagate Expansion 28TB (STKP28000400) sold out at all of them with no backorder option, while third-party sellers ask around $1,000 for a drive that retailed near $290-330. The largest Expansion still buyable at retail price is the 24TB (~$722). This card's 28TB buy link has been retired rather than left pointing at an unbuyable listing. [src10]
• HDD prices surging ~46% due to AI supply crunch: Per TrendForce, HDD contract prices jumped roughly 4% QoQ in Q4 2025 — the sharpest increase in eight quarters — and have risen ~46% since September 2025. WD's CEO confirmed the company is "pretty much sold out for calendar 2026," with enterprise agreements extending to 2028. AI-focused enterprise customers now drive 89% of WD revenue vs. just 5% for consumer sales. HDD manufacturers are running at full utilization yet still can't keep pace with demand, and suppliers warn this pressure will persist through 2026. [src9, src1, src7, src8]
• HAMR is real but not reaching consumers: ServeTheHome's teardown confirmed the Expansion 28TB enclosure contains a Seagate BarraCuda 28TB HAMR drive that Seagate does not sell separately at retail — the external box cost ~$330 while the bare internal HAMR drive listed at ~$569. That shucking arbitrage is exactly why these enclosures disappeared: buyers were stripping them for the drive inside. [src11]
• SSDs are no longer closing the gap — they are losing it: portable SSD pricing has roughly doubled during 2026's NAND shortage, from ~$60-80/TB to ~$110-150/TB, while external HDDs sit at ~$30-45/TB at desktop capacities. For raw performance even budget SSDs deliver 1,000+ MB/s versus HDDs' 120-280 MB/s, but on cost per terabyte the spinning-disk advantage has widened to roughly 3-4x. [src1, src4, src12]
• USB-C transition still stalled: Most portable HDDs still use Micro-B USB connectors, and the WD My Passport "Works with USB-C" name refers to a bundled adapter, not a USB-C port on the drive. True USB-C ports remain rare in HDDs, unlike SSDs where USB-C is standard. A spinning drive cannot saturate more than USB 3.2 Gen 1 (5 Gbps) anyway, so the connector is a convenience issue, not a performance one. [src1, src6]
• 6TB is the portable ceiling: WD's 6TB My Passport is the largest 2.5-inch portable HDD available. Physical limitations of 2.5-inch platters make further increases unlikely. Users needing more portable storage are pushed toward desktop HDDs or external SSDs. [src6]

Important Caveats

• Prices are approximate US street prices verified against live Amazon listings on 2026-08-05, and each is for the exact capacity named in the table row — $/TB is steeply non-linear, so a price for one capacity says nothing about its siblings. The HDD market is in a historically volatile state: prices have surged ~46% since September 2025 due to AI data center demand, and WD/Seagate's full 2026 production is committed to enterprise customers. Listed prices and stock may be outdated within weeks. [src8, src10]
• Stock is a first-class buying constraint on this category right now. At verification time the Seagate Expansion 28TB and the black Seagate One Touch 5TB SKU (STKZ5000400) were both unavailable on Amazon, and the WD Elements Desktop 12TB showed only 2 units left. Check availability before committing to a pick.
• Transfer speeds are manufacturer-rated or single-review maximums. Real-world performance depends on file sizes, fragmentation, and host USB controller, and sequential throughput scales with areal density — a lower-capacity drive in the same family is typically slower than the flagship that was reviewed. Small file transfers are substantially slower than sequential benchmarks.
• All HDDs contain moving parts and are vulnerable to physical shock during operation. SSDs are inherently more durable for travel use.
• Larger portable drives (4TB+) often use SMR (Shingled Magnetic Recording) technology, which can significantly slow down sustained write operations. This primarily affects large multi-terabyte transfers, not typical backup workloads. Manufacturers do not reliably disclose which drive is inside an external enclosure, and the drive can change between production runs.
• Shucking (opening a desktop external to extract the bare drive) is common precisely because externals are often cheaper than the equivalent internal drive — ServeTheHome found a ~$330 external containing a drive that listed at ~$569 bare. It voids the warranty, and there is no guarantee which drive model you will find inside. [src11]
• Desktop HDDs require an AC power adapter and are not suitable for travel or laptop-only use.
• The Seagate Expansion Desktop uses USB-A, not USB-C. For modern laptops with only USB-C ports, an adapter or hub is required.
• Be wary of "refurbished" high-capacity Seagate drives appearing at implausible prices — TechRadar has documented batches of second-hand 28TB units surfacing online during the shortage. [src10]
