#3 in our rankings · Best rugged
SanDisk Extreme Portable SSD
Best for: Travelers and outdoor shooters who need water and dust resistance.
Our recommendation
This is the classic tradeoff in portable storage. Choose the Samsung T7 if the drive carries anything sensitive: AES 256-bit hardware encryption is the deciding feature. Choose the SanDisk Extreme Portable if the drive leaves the house: IP55 sealing, drop protection, and the carabiner loop matter more in the field. Speed is a tie at 1,050 MB/s, so decide on encryption versus ruggedness.
Speed
Effectively identical: both are rated up to 1,050 MB/s read and 1,000 MB/s write over USB 3.2 Gen 2, and benchmarks confirm it. Neither has a meaningful speed advantage, so this comparison is decided on other features.
Protection: encryption vs ruggedness
The T7's AES 256-bit hardware encryption protects data if the drive is lost or stolen, with no performance penalty. The SanDisk counters with IP55 water and dust resistance, 2-meter drop protection, and a carabiner loop. Ask which loss scenario worries you more: a stranger reading your files, or rain killing your drive.
Design and capacities
The T7 is slimmer at about 58 g with a clean aluminum unibody; the SanDisk is rubberized at about 53 g with the loop. SanDisk offers capacities up to 4 TB versus the T7's 2 TB ceiling, which matters for videographers wanting one large field drive.
Choose Samsung T7 Portable SSD if…
- The drive carries client work or personal documents
- You want the slimmest metal design
- Hardware encryption is non-negotiable
Choose SanDisk Extreme Portable SSD if…
- You shoot or work outdoors
- Rain, dust, and drops are real risks
- You need up to 4 TB in one drive

Questions, answered
Which is more reliable long-term?
Both brands have strong track records. Samsung's firmware maturity is slightly ahead; SanDisk's hardware durability is certified. Failure rates in retailer aggregates are low for both.
Can I add encryption to the SanDisk with software?
Yes, tools like VeraCrypt or BitLocker To Go work, but software encryption is less convenient than the T7's built-in hardware solution and can complicate cross-platform use.
