Read/Write Speeds in Practice
On paper, both drives reach up to 1,050 MB/s sequential read — fast enough to edit 4K video directly from the drive or transfer a 100GB project in under two minutes. In sustained real-world transfers, the T7 tends to edge slightly ahead due to Samsung's more refined thermal management in the compact metal chassis. The SanDisk Extreme's speeds are also excellent in real-world tests, typically landing between 900–1,000 MB/s on USB 3.2 Gen 2 connections. For most users the speed difference is imperceptible in daily use.
Durability & Water Resistance
Both drives carry IP65 ratings — sealed against dust and protected against low-pressure water jets from any direction. Neither is submersion-rated for swimming or diving. Both offer 2m drop protection. In practice, the SanDisk Extreme's rubber exterior provides better grip and a slightly more ruggedized feel for outdoor use; the T7's metal housing looks premium but can become slippery when wet. If you work outdoors regularly, the rubber-coated SanDisk may be the more practical choice.
Design & Portability
The Samsung T7's slim metal bar design is one of the most pocketable portable SSDs available — it fits in a jeans coin pocket and weighs just 58g. The SanDisk Extreme is slightly larger with its protective rubber bumper but still highly portable at around 38g. Both clip easily to a keychain lanyard. The T7's design is more office-friendly and aesthetically premium; the SanDisk's design is more outdoors and adventure-oriented.
Security & Encryption
The Samsung T7 offers AES 256-bit hardware encryption via the Samsung Magician software. The premium T7 Shield variant adds a biometric fingerprint scanner for password-free unlocking — a unique feature in this price class. The SanDisk Extreme offers 128-bit AES encryption via the SanDisk SecureAccess software. For professionals handling sensitive client data, the T7's 256-bit encryption and optional fingerprint security provide a stronger security posture.

Frequently Asked Questions
Is there a noticeable speed difference between Samsung T7 and SanDisk Extreme in daily use?
For most daily tasks — copying photos, editing video, transferring files — you will not notice a meaningful difference. Both reach ~1,050 MB/s sequential read. In sustained large file transfers over 10+ minutes, the T7 may maintain peak speeds slightly longer due to its thermal design, but the difference is typically under 5% in real-world conditions.
Can I use these SSDs with a PS5 or Xbox Series X?
Yes. Both drives work as extended storage for PS4/PS5 and Xbox Series X/S via USB. Note that PS5 games cannot run from USB storage (they must be installed on the internal NVMe), but you can store and transfer PS5 games between the external drive and internal SSD. Xbox Series X/S can run Series X/S optimized games from certain external SSDs — check Microsoft's compatibility list.
What does the IP65 rating actually mean for these drives?
IP65 means the drive is completely sealed against dust ingress (the "6") and protected against water jets from any direction (the "5"). It does not mean waterproof for submersion — dropping either drive in a lake, pool, or puddle deeper than a splash is not covered. For submersion resistance you would need IP67 or IP68.
Is the Samsung T7 Shield worth the extra cost over the standard T7?
If you regularly carry sensitive data — client files, financial records, unreleased creative projects — the fingerprint scanner on the T7 Shield is genuinely useful. It removes the friction of entering a password every time while maintaining strong security. If your drive holds non-sensitive files, the standard T7 is sufficient.
Do these drives work with Android phones?
Yes, with a USB-C OTG adapter. Both drives work with Android phones and tablets for file transfer and as external storage. Transfer speeds are limited by the phone's USB controller but typically reach 300–500 MB/s on modern flagship phones with USB 3.2 Gen 2 ports.
Should I worry about the SanDisk reliability issues I've seen mentioned online?
Earlier SanDisk Extreme V1 (2020) models had firmware bugs that caused data loss for some users, which damaged the brand's reputation. Western Digital (which owns SanDisk) issued firmware patches. The current Extreme V2 and later models have resolved these issues and show normal failure rates. Regardless of drive brand, maintaining regular backups is essential practice.
Which is better for video editors who edit directly from the drive?
Both drives are fast enough for editing 4K H.264/H.265 footage directly. For 8K RAW or high-bitrate ProRes editing, both may experience occasional slowdowns during sustained transfers — in this scenario, a Thunderbolt 3/4 SSD enclosure with an NVMe drive would be more appropriate. For 4K editing workflows either drive is excellent.
How do I maximize transfer speeds with these drives?
Always connect to a USB 3.2 Gen 2 (10Gbps) port on your computer — often labeled with a lightning bolt symbol or "USB 3.1/3.2 Gen 2". Use the included USB-C to USB-C cable for best performance. Avoid using a USB hub — direct connection to the computer port gives the fastest speeds. On Mac, ensure the drive is formatted as exFAT or APFS for macOS compatibility.
