The SanDisk Extreme Portable SSD V2 is a fast, rugged 1TB drive: rated 1050/1000 MB/s, class-leading sustained writes in published tests, IP65 sealing and a 52 g body photographers trust. But the 2023 firmware fiasco — confirmed by WD after data-loss reports — stains the record. Buy an updated-firmware listing, run the updater on older units, and keep a backup.
— THE VERDICT · JUDGEANY EDITORSWhat the Extreme V2 is
The Extreme V2 arrived in 2020 as a real generational jump: NVMe inside instead of SATA, USB 3.2 Gen 2 outside — rated 1050 MB/s read, 1000 MB/s write, about double the old drive. The 1TB black is model SDSSDE61-1T00-G25; sizes run 500GB to 4TB. SanDisk kept the silicone-wrapped shell and carabiner loop, and ships a USB-C cable plus a USB-C to USB-A adapter.
The specs that matter
Those headline speeds need a 10Gbps USB 3.2 Gen 2 port on both ends — plug into an older 5Gbps port and the drive caps around 550 MB/s. The toughness story is real: IP65 dust and water resistance (early pages listed IP55; current listings carry the higher rating), 3-meter drop protection, a 52 g body, 256-bit AES hardware encryption, and a 5-year warranty.
What published tests found
Tom's Hardware put the V2 through its paces: sequential speeds on par with the class, 4K random reads weaker than the original. But sustained writes were the surprise — the V2 outlasted the WD My Passport SSD, Samsung T7 Touch and Crucial X8 across 15 minutes of hammering, its small ~12GB SLC cache recovered fast, and the surface stayed under 45°C with no throttling. Tech Advisor measured 1,027/958 MB/s on the 1TB — near enough the rated spec — and warned buyers to confirm listings quote 1050/1000MB/s, not the V1's 550/500. Digital Camera World called it excellent in almost all regards. We don't run a lab; these are published findings, and the scores below are editorial judgments based on them.
The 2023 firmware problem you should know about
In 2023 Western Digital confirmed a firmware issue that could make Extreme V2 and Extreme Pro V2 drives drop off the computer without warning — and in some cases become unreadable. The Verge lost 3TB on a vendor replacement, class actions followed, and PetaPixel said it could no longer recommend the line. WD released a firmware updater, and current listings ship with the fix. If your drive predates mid-2023 — or you're buying used — run the updater before trusting it with anything you can't lose.
What owners praise — and complain about
Owner sentiment runs strongly positive on speed for photo and video work and the pocketable ruggedness — the carabiner loop gets used. The recurring complaints are small but real: no power or activity LED, a short bundled cable for desktop setups, and rivals like the Samsung T7 Shield and Crucial X8 often undercut it on price. The V1-versus-V2 naming confusion also trips buyers — check the listed speeds before ordering.
Who should buy it
Photographers and videographers who want a fast drive that shrugs off dust and drops should consider it — check it live on Amazon and buy an updated-firmware listing. Skip it if you need 2GB/s-plus speeds (that means Gen 2x2 and the pricier Extreme Pro), if your machines only have 5Gbps ports, or if the unit you own runs pre-fix 2023 firmware you haven't updated.
