SanDisk Extreme Portable SSD 1TB Review UK 2025
Portable storage has become non-negotiable for anyone working with video files, RAW photos, or large project folders. The SanDisk Extreme Portable SSD 1TB promises speeds up to 1050MB/s with rugged protection that can survive drops and weather. After using this drive daily for three weeks—transferring 4K footage, backing up photo shoots, and moving game libraries between systems—I’ve found it delivers on speed but comes with some compromises that aren’t immediately obvious from the spec sheet.

The SanDisk Extreme Portable SSD 1TB is the portable drive I’d recommend to anyone working with large files who needs reliability over absolute maximum capacity. At £111.97, it costs more than budget SSDs but the combination of speed, durability, and the five-year warranty makes it worthwhile for professionals who can’t afford data loss or workflow delays.
What I Tested
📊 See how this compares: SanDisk Extreme vs Samsung T7: Ultimate SSD Showdown (2025)
The SanDisk Extreme Portable SSD 1TB arrived at my desk three weeks ago and immediately became my go-to drive for video editing projects. My testing focused on real-world scenarios: transferring 120GB of Sony A7 IV RAW files from an on-location shoot, moving a 180GB Premiere Pro project between my desktop and the Apple MacBook Air M4 2025, backing up Steam games, and using it as scratch disk storage during 4K timeline scrubbing.
I ran CrystalDiskMark benchmarks on both Windows 11 and macOS Sequoia, performed sustained write tests with 50GB file transfers to check for thermal throttling, and deliberately tested the durability claims by dropping it from waist height onto concrete (twice) and leaving it in my car boot during a rainy week. The drive connected via USB-C to USB-C on modern machines and USB-C to USB-A using the included adapter for older systems.
Temperature monitoring showed the aluminium chassis gets warm during sustained writes—around 45°C after 10 minutes of continuous data transfer—but never uncomfortably hot. The rubberised shell provides decent grip, though the carabiner loop feels like an afterthought rather than something you’d trust with expensive kit.
Price Analysis: Where the SanDisk Extreme Sits in 2025
Currently priced at £111.97, this drive sits above typical budget portable SSDs but below Samsung’s T7 Shield equivalent. The 90-day average of £96.86 suggests the current price represents a slight premium—if you’re not in a rush, waiting for it to drop back under £100 makes sense.
For context, generic 1TB portable SSDs hover around £70-80, whilst premium options like the Samsung T7 Shield or Crucial X9 Pro range from £100-130 depending on sales. The SanDisk occupies middle ground: faster than budget drives, tougher than most, but lacking the absolute peak speeds of £150+ NVMe enclosures.
The five-year warranty adds value that cheaper drives can’t match. When you’re storing irreplaceable footage or client work, that peace of mind justifies the extra £20-30 over no-name alternatives. Over 100,000 Amazon reviews with a 4.5-star average suggests reliability issues are uncommon.
Performance: Speed Tests and Real-World Transfer Rates
SanDisk claims up to 1050MB/s read and 1000MB/s write speeds. My testing confirmed these figures are achievable—but only under specific conditions. Connected to a USB 3.2 Gen 2 port on my desktop, CrystalDiskMark returned 1042MB/s sequential read and 991MB/s write. That’s genuinely fast for a portable drive.
Real-world transfers told a more nuanced story. A 47GB folder of mixed RAW files and JPEGs transferred from my desktop to the SanDisk in 52 seconds—averaging around 900MB/s. A single 28GB video file moved at 980MB/s sustained. Smaller files (under 1GB) transferred at 600-750MB/s due to overhead. These speeds make the drive usable as direct editing storage for 4K timelines, though 6K or 8K footage might occasionally stutter depending on codec.
Thermal performance proved solid. During a sustained 180GB transfer, speeds remained consistent above 850MB/s for the entire duration. The chassis got warm but never throttled. Compared to cheaper drives that slow to 400-500MB/s after filling the SLC cache, the SanDisk maintains performance impressively.
One limitation: the drive ships formatted exFAT, which works across Windows and Mac but doesn’t support file permissions or journaling. Reformatting to NTFS or APFS locks you to one ecosystem. For cross-platform work, you’re stuck with exFAT’s limitations.
Durability and Build Quality
The IP65 rating means dust can’t penetrate and water jets from any direction won’t damage it. I tested this by running it under a tap for 30 seconds—it continued working without issue. The three-metre drop protection proved legitimate: dropping it twice onto concrete from waist height left only cosmetic scuffs on the rubber shell. The drive still functions perfectly.
The rubberised exterior provides grip but attracts dust and pocket lint aggressively. After a week in my camera bag, it looked grubby. The aluminium core underneath feels premium, but you’ll never see it thanks to the permanent rubber jacket. The carabiner loop is moulded plastic—it works for clipping to a bag strap but I wouldn’t trust it dangling from a belt loop whilst hiking.
Physical size is compact: 100.5 x 49.5 x 8.9mm and 52 grams. It fits comfortably in a jeans pocket, though the squared-off edges dig in slightly. The included 30cm USB-C to USB-C cable is adequate but short—you’ll want a longer cable for desktop use. The USB-C to USB-A adapter is a nice inclusion for older machines.
Comparison: SanDisk Extreme vs Alternatives
| Drive | Price | Speed | Durability | Key Difference |
|---|---|---|---|---|
| SanDisk Extreme 1TB | £111.97 | 1050MB/s read | IP65, 3m drop | Best balance of speed and protection |
| Samsung T7 Shield 1TB | £119.99 | 1050MB/s read | IP65, 3m drop | Similar specs, slightly higher price |
| Crucial X9 1TB | £79.99 | 1050MB/s read | Basic (no IP rating) | Budget option without rugged features |
The Samsung T7 Shield matches the SanDisk on paper but costs £8 more currently. In my experience, they perform identically—your choice comes down to brand preference and which is cheaper when you’re buying. The Crucial X9 saves £32 but lacks water resistance and drop protection. For studio use where the drive never leaves your desk, the X9 makes sense. For field work, the extra durability justifies the SanDisk’s premium.
Software and Security Features
The drive includes SanDisk’s SecureAccess software for password protection with 256-bit AES hardware encryption. Setup is straightforward on Windows and macOS (10.9 or later required). You create a password, and the software creates an encrypted vault on the drive. Files dragged into the vault are encrypted automatically.
The catch: you need to install the software on every machine you want to access encrypted files from. For a single-user scenario, this works fine. For collaborative work where multiple people need access, it becomes cumbersome. The encryption is hardware-based, so performance doesn’t suffer noticeably—encrypted file transfers ran at 920-950MB/s, barely slower than unencrypted.
There’s no iOS or Android app, limiting mobile device compatibility. You can connect the drive to a phone via USB-C and access unencrypted files through the file manager, but encrypted vaults remain locked without desktop software.
What Buyers Say: Analysis of 100,000+ Reviews
With over 100,331 verified purchases and a 4.5-star rating, the SanDisk Extreme enjoys strong customer satisfaction. Common praise focuses on reliability, speed, and build quality. Photographers and videographers frequently mention using it for years without issues, backing up terabytes of data without failures.
The most common complaint involves the short included cable—many buyers immediately purchase a longer USB-C cable. Some users report the rubber coating degrading after 18-24 months of heavy use, becoming sticky or peeling at the edges. This doesn’t affect functionality but looks tatty.
A small percentage (around 2-3% based on review analysis) report drive failures within the first year. SanDisk’s warranty process gets mixed feedback—some users describe quick replacements, others mention weeks of back-and-forth. This failure rate is typical for SSDs and lower than many budget alternatives.
Mac users occasionally mention compatibility issues with Time Machine backups—the drive works but some report sporadic disconnections during overnight backups. Formatting to APFS rather than leaving it as exFAT seems to resolve this for most affected users.

Who Should Buy the SanDisk Extreme Portable SSD 1TB
Buy if you: Work with large video files or RAW photos that need fast transfers. Shoot on location and need storage that can handle rough treatment. Want a reliable backup drive with a decent warranty. Need something compact enough for daily carry but fast enough for direct editing.
Skip if you: Only need basic file storage and don’t require rugged features—the Crucial X9 saves £32 for similar speeds. Want maximum capacity per pound—2TB mechanical drives cost less. Need the absolute fastest speeds possible—NVMe enclosures with Thunderbolt hit 2500MB/s+ but cost significantly more.
For photographers backing up shoots, videographers moving footage between edit stations, or anyone who needs dependable portable storage, the SanDisk Extreme 1TB hits the sweet spot. It’s not the cheapest option, but the combination of speed, durability, and warranty makes it worthwhile for professional use.
Budget-conscious buyers might prefer the Crucial X9 at around £80 if they don’t need water resistance. Those building more permanent storage solutions should consider the UGREEN NASync DH2300 NAS for centralised backup with RAID protection.
Final Verdict
The SanDisk Extreme Portable SSD 1TB is the portable drive I’d recommend to anyone working with large files who needs reliability over absolute maximum capacity. The speeds are genuinely fast, the durability features actually work, and the five-year warranty provides confidence that cheaper alternatives can’t match.
At £111.97, it costs more than budget portable SSDs, but you’re paying for proven reliability backed by over 100,000 user reviews. The rubber coating attracts dust and the included cable is annoyingly short, but these are minor frustrations in an otherwise excellent package.
For content creators, photographers, or anyone who can’t afford data loss or workflow delays, this drive justifies its premium. It’s been my daily-carry storage for three weeks and has handled everything from 4K timeline editing to outdoor shoots in questionable weather without complaint. That’s exactly what you want from portable storage—performance you can rely on, even when conditions aren’t ideal.
Rating: 4.5/5 – Excellent portable SSD that balances speed, durability, and value for professional users.
