External Solid State Drives Price Comparison

External SSDs have quietly become one of the most competitive corners of the storage market. Prices have dropped sharply over the past two years, and you can now pick up a genuinely fast 1 TB drive for well under 200 £ — something that would have seemed optimistic not long ago. We've tracked 517 products across this category, and the spread is striking: entry-level options start from 92 £, while specialist encrypted drives from iStorage push well beyond 301 £.

SanDisk dominates the listings by sheer volume, and for good reason — the Extreme and Extreme PRO lines offer a reliable combination of speed and durability that suits most users. Samsung's T7 and T9 series are the perennial rivals, typically priced slightly higher but with a reputation for consistency that John Lewis and Currys customers tend to reward with strong review scores. Kingston's XS2000 is the outsider worth watching: it punches above its weight on sequential read speeds and often undercuts the big two on price.

One thing our data makes clear: iStorage's average price of over £1,000 isn't a mistake — it reflects a completely different product category. Those drives are hardware-encrypted, PIN-protected devices aimed at government, healthcare, and legal sectors where data encryption is a compliance requirement, not a nice-to-have. If you're a home user or creative professional, you almost certainly don't need one.

For most buyers, the real decision sits between USB 3.2 Gen 1 (up to 400 MB/s) and Gen 2 (up to 1,000 MB/s in practice). The price gap between the two has narrowed considerably, so unless you're on a tight budget, Gen 2 is worth the modest premium. Photographers shooting RAW, video editors working with 4K footage, and anyone backing up large datasets regularly will feel the difference immediately. If you're just archiving documents and the odd photo, Gen 1 is perfectly adequate — and you'll save a few pounds in the process.

It's also worth comparing external SSDs against external hard drives before committing. HDDs still offer far more capacity per pound at the high end, but they're heavier, slower, and far more vulnerable to knocks. For anything that travels in a bag, an SSD is the sensible choice. And if portability isn't a priority at all, a NAS server might serve you better for home or office use.

How to Choose an External SSD: The Criteria That Actually Matter

With prices ranging from 92 £ to well over 301 £, picking the right external SSD isn't just about grabbing the cheapest option. The interface version, capacity, and durability rating can make the difference between a drive that transforms your workflow and one that bottlenecks it. Here's what to focus on.

USB Interface Version: Gen 1 vs Gen 2

This is the single biggest performance differentiator and the one most buyers overlook. USB 3.2 Gen 1 tops out at around 400 MB/s in real-world use; Gen 2 can reach 900–1,000 MB/s with a good drive. For transferring a 50 GB video project, that's the difference between roughly two minutes and under a minute. The price gap between Gen 1 and Gen 2 drives has narrowed — often just a few pounds at the 1 TB mark — so we'd recommend Gen 2 as the default unless you're on a strict budget. Also check the cable: a Gen 2 drive connected via a Gen 1 cable or port will be throttled regardless.

Capacity vs. Cost Per GB

The sweet spot shifts constantly, but 1 TB is currently where you get the best value per gigabyte for most buyers. 500 GB drives are cheaper upfront but rarely proportionally so — you often pay 60–70% of the 1 TB price for half the space. At the other end, 4 TB and 8 TB external SSDs carry a significant premium; unless you specifically need that capacity in a portable form factor, a desktop external HDD or NAS will serve you better at a fraction of the cost. For photographers and videographers, 2 TB is increasingly the practical minimum for a working drive.

Durability Rating for On-the-Go Use

Not all external SSDs are built to survive a bag. Entry-level models have plastic shells with no formal protection rating — fine for desk use, risky if they're travelling. Look for IP53 or higher (dust and splash resistance) and a drop resistance rating of at least 1.5 metres if the drive is going to live in a rucksack or camera bag. SanDisk's Extreme line and the Kingston XS2000 both carry meaningful drop ratings. A rubberised casing isn't just aesthetic — it genuinely absorbs impact. If you're working outdoors or on location, this criterion should rank above raw speed.

Hardware Encryption: Who Actually Needs It

AES 256-bit hardware encryption is essential for anyone handling sensitive client data, medical records, or anything subject to GDPR compliance. iStorage specialises in this space, with PIN-authenticated drives that meet government security standards — which explains their average price sitting well above 301 £. For everyone else, software encryption (available free via BitLocker on Windows or FileVault on macOS) is sufficient. Don't pay a premium for hardware encryption unless your use case genuinely demands it.

Thermal Performance During Sustained Transfers

This is rarely mentioned in spec sheets but matters in practice. Some compact SSDs throttle their write speeds significantly after the first few minutes of sustained transfer — the NAND gets hot, and the controller backs off to protect it. Drives with aluminium housings or any form of passive heat dissipation handle this far better than pure plastic shells. If you regularly transfer large batches of files (think: backing up a full shoot, or moving a game library), check independent reviews for thermal throttling behaviour rather than relying on peak speed figures alone.

Warranty Length as a Reliability Signal

A 5-year warranty isn't just reassurance — it's a statement from the manufacturer about expected lifespan. SanDisk and Samsung both offer 5-year warranties on their Extreme lines; budget brands often cap at 1–2 years. In the UK, your statutory rights under the Consumer Rights Act provide some protection regardless, but a longer manufacturer warranty means faster, hassle-free replacements. When comparing two similarly priced drives, warranty length is a legitimate tiebreaker.

• Entry-level portable (From 92 £ to 145 £) : Drives in this bracket are typically USB 3.2 Gen 1, with sequential reads around 400–550 MB/s. Brands like Intenso, Verbatim, and Transcend dominate here. Fine for document backup and light media use, but don't expect sustained high-speed transfers. Plastic shells, minimal drop protection, and shorter warranties are the norm. A reasonable starting point if portability and speed aren't priorities.
• The sweet spot (From 145 £ to 200 £) : This is where the market gets interesting. You'll find Gen 2 drives from SanDisk (Extreme), Kingston (XS2000), and Samsung (T7) at 1 TB capacity. Real-world speeds of 800–1,000 MB/s, decent drop resistance, and 3–5 year warranties. For most home users, photographers, and students, this range offers everything needed without overpaying. The SanDisk Extreme V2 and Kingston XS2000 500G both sit here and represent strong value.
• For the performance-conscious (From 200 £ to 301 £) : Higher capacities (2 TB) and faster drives (Extreme PRO, Samsung T9) live here. Speeds can exceed 1,000 MB/s sustained, with better thermal management. LaCie's Rugged range also appears at this level — built for field use with IP67 ratings. Suited to video editors, creative professionals, and anyone who needs a reliable 2 TB working drive. Worth the step up if you're regularly moving large files.
• Specialist and high-capacity (Over 301 £) : Above this threshold, you're looking at 4 TB+ portable SSDs, iStorage encrypted drives, or LaCie's professional Rugged series. The iStorage products are a category apart — hardware-encrypted, PIN-authenticated, and priced accordingly. The SanDisk 8 TB and WD Extreme PRO 4 TB sit here for capacity reasons. Only buy in this range if you have a specific professional need; for most users, the sweet spot range delivers better value.

Top products

• SanDisk SDSSDE30-1T00-G26 external solid state drive 1 TB USB Type-C 3.2 Gen 2 (3.1 Gen 2) Black (SanDisk — 4.2/5) : The most-listed drive in this category and a solid all-rounder at 1 TB — but it's the entry-level SanDisk, not the Extreme. Speeds are modest compared to the PRO line; fine for everyday backup, less suited to video editing workflows.
• SanDisk Extreme V2 1 TB USB Type-C 3.2 Gen 2 (3.1 Gen 2) Blue (SanDisk — 4.5/5) : The sweet spot in SanDisk's lineup — Gen 2 speeds, IP55 rating, and a 5-year warranty at a price that sits right at the Q1 threshold. Excellent value for photographers and travellers. The blue colourway is a bonus if aesthetics matter to you.
• Kingston Technology 500G PORTABLE SSD XS2000 (Kingston Technology — 4.3/5) : The outsider worth considering. Kingston's XS2000 punches above its price with genuine Gen 2 performance and a compact rubberised shell. The 500 GB capacity limits its appeal, but for a secondary travel drive it's hard to fault.
• SanDisk Extreme PRO Portable 1 TB USB Type-C 3.2 Gen 2 (3.1 Gen 2) Black (SanDisk — 4.6/5) : The top of SanDisk's portable range and genuinely excellent for professional use — sustained reads above 1,000 MB/s, IP55 protection, and a metal casing that dissipates heat far better than plastic rivals. The premium over the Extreme V2 is justified if you're doing sustained large transfers regularly.
• Kingston Technology 2000G PORTABLE SSD XS2000 (Kingston Technology — 4.4/5) : The 2 TB XS2000 sits right at the median price point and offers strong competition to Samsung's T7 at this capacity. Kingston's pricing is typically more aggressive than SanDisk at the 2 TB mark — worth comparing directly before defaulting to the better-known brand.
