USB 3.2 Gen 2×2 portable SSDs have become affordable, and these two are the ones most buyers land on. Both deliver real-world transfer speeds over 2000 MB/s — meaningfully faster than older USB-A drives. The Samsung T9 and SanDisk Extreme Pro V2 are priced close together and aimed at the same buyer: someone who moves large files between devices and wants them to survive being in a bag.
SanDisk Extreme Pro V2
The SanDisk Extreme Pro V2 has a slight edge thanks to IP65 dust and water resistance and marginally faster sustained write speeds. The Samsung T9 is the better pick if you want Samsung's excellent software ecosystem and slightly better build quality feel.

Transfer Speed
Tom's Hardware clocked the T9 at around 2000 MB/s read and 1960 MB/s write over USB 3.2 Gen 2×2. The Extreme Pro V2 hits similar reads but sustained write performance holds up better in their testing — around 2000 MB/s write with less speed drop-off on large files.
Both require a USB 3.2 Gen 2×2 port to hit these speeds. On a standard USB 3.2 Gen 2 (single-lane) port, both cap around 1000 MB/s. Check your laptop's spec sheet before expecting the top-end numbers.
Durability
The SanDisk Extreme Pro V2 carries IP65 certification — dust-tight and water-resistant to low-pressure jets. It's survived drop tests and bag abuse in reviewer testing. The Samsung T9 has a rubberized bumper and passes a 3-meter drop test but lacks IP dust resistance.
For outdoor photographers or anyone who uses their drive at job sites, the IP65 rating on the SanDisk is worth something real.
Software
Samsung Magician works beautifully with the T9, giving you health monitoring, firmware updates, and secure erase. SanDisk's SecureAccess is functional but feels dated. If you want strong drive management software, Samsung wins this dimension cleanly.
Both drives use 256-bit AES hardware encryption. The T9 has a fingerprint reader on the 2TB model — a genuinely useful feature if you're carrying sensitive data.
Compatibility and Accessories
Both drives include a USB-C to USB-C cable and a USB-C to USB-A adapter. That covers most modern laptops and older desktops. Neither requires external power — they draw from the USB port.
The Samsung T9 formats as exFAT out of the box for cross-platform use. The SanDisk Extreme Pro V2 also uses exFAT. Both work on Windows, macOS, and Android without reformatting.

FAQ
Do these work at full speed on a Mac?
Yes, if your Mac has a Thunderbolt 4 or USB 3.2 Gen 2×2 port. Most M-series MacBook Pros support 20 Gbps. Check your model's USB spec.
Can I use these as a PS5 external drive?
For extended storage of PS4 games, yes. You can't run PS5 titles from external USB drives — those require the M.2 internal slot.
