Our Pick
samsung-t7
Samsung T7 Portable SSD
- ✓Up to 1,050 MB/s read via USB 3.2 Gen 2
- ✓942 MB/s sustained write average over 200GB with no throttling in testing
- ✓Aluminum unibody doubles as a heatsink, 85 x 57 x 8mm, 58g
- ✓AES 256-bit hardware encryption via Samsung Magician software
- ✓Rated for 2-meter drops; no IP water/dust rating
- ✓3-year limited warranty
Pros
- 942 MB/s sustained write speed held steady with no throttling across a 200GB test transfer
- Smallest, slimmest form factor in the category — fits in a jeans coin pocket
- Aluminum body provides real thermal advantage on large continuous transfers (100GB+)
- $10-20 cheaper than the SanDisk Extreme at the same 1TB capacity
- Samsung Magician software is cleaner and more polished than SanDisk's SecureAccess
Cons
- No IP rating — water or dust exposure risks damage that the SanDisk Extreme would survive
- No carabiner loop or rugged casing for field or production-set attachment
- Encryption setup requires Samsung Magician on Windows/Mac — no native Linux support
- Peak sequential write (988 MB/s) trails the SanDisk Extreme's 1,001 MB/s in raw benchmarks
SanDisk Extreme Portable SSD V2
- ✓Up to 1,050 MB/s read via USB 3.2 Gen 2
- ✓IP55 rating: protected against water jets and dust ingress
- ✓Rubberized plastic body with integrated carabiner loop, 100 x 55 x 9mm, 49g
- ✓AES 256-bit hardware encryption via SanDisk SecureAccess software
- ✓Rated for 2-meter drops
- ✓3-year limited warranty (WD/SanDisk)
Pros
- IP55 rating is a genuine, testable protection against rain, splashes, and dust — not a marketing claim
- Carabiner loop attaches directly to a bag, camera strap, or gear panel without extra accessories
- Slightly higher peak sequential write speed (1,001 MB/s) than the Samsung T7 in benchmarks
- Lighter than the T7 (49g vs 58g) despite the rugged casing
- The only sensible choice for outdoor, film-set, or near-water use cases
Cons
- Sustained write speed drops to 850 MB/s at the 9-minute mark on large transfers, unlike the T7's steady 942 MB/s
- $10-20 more expensive than the Samsung T7 at the same 1TB capacity
- SecureAccess software is functionally adequate but less polished than Samsung Magician
- Slightly larger and thicker than the T7, less pocket-friendly for everyday carry
Samsung T7 and SanDisk Extreme are the two most bought portable SSDs in the $90-100 price range. They are nearly identical in peak speed and differ in two concrete ways: the T7 has a better sustained write performance and smaller size; the Extreme has IP55 weather protection and a carabiner loop for field attachment.
The Choice in One Sentence
Buy the T7 if you use your drive at a desk, in a bag, or in climate-controlled environments.
Buy the SanDisk Extreme if you work outdoors, on film sets, in kitchens, near water, or anywhere your drive might get wet or dusty.
Design
Samsung T7: aluminum, 85 x 57 x 8mm, 58g. The slimmest portable SSD in the category. Fits in a jeans coin pocket. Aluminum body acts as a heatsink.
SanDisk Extreme: rubberized plastic with carabiner loop, 100 x 55 x 9mm, 49g. Slightly longer and thicker than the T7. Lighter due to plastic body. Carabiner loop attaches to a production bag, camera strap, or gear panel without additional accessories.
Transfer Speed: Real-World
Both drives are rated at up to 1,050 MB/s read via USB 3.2 Gen 2.
In our sequential write test (CrystalDiskMark):
- Samsung T7: 988 MB/s
- SanDisk Extreme V2: 1,001 MB/s
In our 200GB sustained write test (mixed video files):
- Samsung T7: averaged 942 MB/s, no throttling observed
- SanDisk Extreme V2: averaged 911 MB/s, slight drop to 850 MB/s at the 9-minute mark
The difference in day-to-day use is negligible. If you are copying a 50GB project folder, both drives finish in approximately 55-60 seconds. The T7's thermal advantage matters only for very large continuous transfers (100GB+) over multiple consecutive operations.
Durability
Samsung T7: rated to 2-meter drops. No IP rating — water and dust protection is not certified.
SanDisk Extreme: IP55 rating (protected against water jets from any direction, protected against dust ingress in most conditions). Rated to 2-meter drops.
IP55 vs no IP rating: this is the most concrete differentiator. IP55 means you can use the Extreme in rain, splash water on it, or drop it near a puddle without concern. The T7 in the same situation risks damage.
Encryption
Both drives offer AES 256-bit hardware encryption. Both require manufacturer software to set up:
- Samsung T7: Samsung Magician (Windows/Mac)
- SanDisk Extreme: SanDisk SecureAccess (Windows/Mac)
Neither supports encryption setup on Linux without third-party tools. For unencrypted use, both work on all operating systems without software.
Price
- Samsung T7 1TB: typically $89-99
- SanDisk Extreme 1TB: typically $99-109
The T7 is consistently $10-20 cheaper. Over a 3-year ownership period, that difference is minor. Do not let price be the deciding factor — choose based on whether you need IP55.
Software
Samsung Magician: cleaner interface, S.M.A.R.T. monitoring, firmware updates, performance optimization. Better software.
SanDisk SecureAccess: basic encryption and password setup. Functionally adequate but less polished.
Warranty
Both: 3-year limited warranty. WD (SanDisk's parent company) has a similar RMA process to Samsung. Neither has a meaningful advantage here.
The Verdict
If your portable SSD stays on a desk, in a bag, or in dry indoor environments: Samsung T7. Better thermal management, smaller size, lower price, better software.
If your portable SSD goes on set, outdoors, near water, or in dusty environments: SanDisk Extreme. IP55 protection is not a marketing feature — it is a meaningful difference that matters when accidents happen.
