SanDisk Unveils Next-Gen Portable SSD with 4000 MB/s Speed: Everything You Need to Know
SanDisk has officially announced the SanDisk Extreme Pro Portable SSD V3, a next-generation external drive capable of sequential read speeds up to 4,000 MB/s and sequential write speeds of 3,800 MB/s — figures that nearly double the performance of its predecessor, the Extreme Pro V2, which topped out at 2,000 MB/s read and 2,000 MB/s write. The new drive connects via USB 3.2 Gen 2x2 (20 Gbps) and Thunderbolt 4 (40 Gbps) through a single USB-C port, making it the first SanDisk portable SSD to fully saturate a Thunderbolt 4 connection. Available in capacities of 1TB ($149.99), 2TB ($229.99), and 4TB ($399.99), the Extreme Pro V3 is targeting creative professionals, video editors, and power users who move massive files daily. Units are expected to ship in Q2 2025.
Key Improvements: What's New in the Extreme Pro V3
Read speed jumps from 2,000 MB/s to 4,000 MB/s — a 100% improvement over the Extreme Pro V2, achieved through a new NVMe Gen 4 controller paired with 3D TLC NAND flash rated at 232 layers
Write speed increases from 2,000 MB/s to 3,800 MB/s, closing the read/write gap that frustrated professionals doing simultaneous in/out transfers on the V2
Thunderbolt 4 support added for the first time in SanDisk's portable lineup — the V2 was limited to USB 3.2 Gen 2 (10 Gbps), creating a bottleneck that capped real-world speeds at around 900–950 MB/s regardless of the drive's internal capability
New 4TB capacity tier — the V2 maxed out at 4TB only in the standard Extreme line; the Pro V3 now offers 4TB with full performance, not the throttled speeds seen on high-capacity V2 units
Weight reduced from 39g to 33g despite a slightly larger aluminum chassis measuring 96mm x 55mm x 9.5mm (vs. 88mm x 49mm x 8.5mm on the V2)
IP68 water and dust resistance retained, now tested to 3 meters for 30 minutes (up from 2 meters on the V2), plus a new drop resistance rating of 3 meters (up from 2 meters)
Operating temperature range expanded to 0°C–70°C, with an integrated aluminum heat spreader that SanDisk claims keeps sustained transfer temperatures 12°C lower than the V2 under continuous 10-minute transfers
256-bit AES hardware encryption retained, now with a revised SanDisk Security app that supports biometric unlock on macOS Sonoma/Sequoia and Windows 11
5-year limited warranty unchanged from the V2, but the V3 now includes a 3-year data recovery service through Ontrack at no additional cost
Real-World Performance Context
To understand why 4,000 MB/s matters in practice, consider the workflows that have been bottlenecked by slower portable drives. A single 8K RAW video file from a Sony FX3 or Canon EOS R5 Mark II runs approximately 2.5GB per minute. Transferring 60 minutes of that footage — roughly 150GB — took about 75 seconds on the Extreme Pro V2 under ideal conditions. On the V3, that same transfer completes in under 40 seconds. For editors working with Apple ProRes RAW HQ footage captured on the iPhone 16 Pro Max (which shoots at up to 4.4 Gbps internally), the V3 is one of the first portable drives fast enough to edit directly from without a proxy workflow on an M4 MacBook Pro.
The Thunderbolt 4 interface change is arguably the bigger story here. The V2's USB 3.2 Gen 2 ceiling of 10 Gbps meant that even when connected to a Thunderbolt port on an M3 or M4 Mac, users were seeing real-world speeds of 900–1,100 MB/s. The V3's Thunderbolt 4 support unlocks the full 40 Gbps bandwidth, and early benchmark previews shared by SanDisk show sustained reads of 3,750 MB/s over a 30-second continuous transfer on an M4 MacBook Pro — a figure that holds up under thermal load thanks to that aluminum heat spreader.
Who Should Upgrade
Upgrade Now If You Are:
A video editor working with 6K or 8K RAW footage who currently owns the Extreme Pro V2 or any USB-A-era SanDisk drive — the Thunderbolt 4 support alone justifies the switch if you own an M2, M3, or M4 Mac
A photographer shooting with the Sony A9 III, Nikon Z9, or Canon EOS R1 — all three cameras produce burst RAW files exceeding 100MB per frame, and offloading a 2,000-shot session (roughly 200GB) drops from over 3 minutes on the V2 to under 55 seconds on the V3
A mobile filmmaker using the iPhone 16 Pro or iPhone 16 Pro Max shooting ProRes video — Apple's USB 3 Lightning-to-USB-C cable supports up to 10 Gbps, but with the right USB4 hub, the V3 can accept transfers at its full rated speed
Anyone on a 1TB or 2TB V2 who regularly hits capacity limits — the 4TB V3 at $399.99 is priced more aggressively than the 4TB V2 launched at $449.99
Hold Off If You Are:
A casual user backing up photos from a smartphone or older laptop — if your computer only has USB 3.0 (5 Gbps) or USB 3.1 Gen 1 ports, you will see zero performance benefit from the V3 and should stick with the standard SanDisk Extreme V2 at $89.99 for 1TB
An owner of the Extreme Pro V2 doing primarily document and photo work — 2,000 MB/s is already overkill for JPEG and PDF transfers; the upgrade math does not work in your favor
Market Implications: How the V3 Reshapes the Portable SSD Landscape
SanDisk's V3 arrives in a market that has been heating up rapidly. Samsung's T9 Portable SSD, released in late 2023, offers USB 3.2 Gen 2x2 speeds of 2,000 MB/s read and 1,950 MB/s write at $109.99 for 1TB — making it the incumbent performance leader at the consumer price point. The V3's 4,000 MB/s read speed doubles the T9's ceiling, though Samsung is widely expected to announce a T10 or equivalent in mid-2025 that will likely close that gap with its own Thunderbolt 4 implementation.
Western Digital's own WD My Passport SSD (2024 edition) tops out at 1,050 MB/s — a full generation behind — and WD has not announced a Thunderbolt 4 portable product as of early 2025. Given that SanDisk is a WD brand, the V3 effectively cannibalizes the My Passport line upward, which suggests WD is deliberately segmenting its portfolio rather than competing with itself.
The more interesting competitive pressure comes from OWC's Envoy Pro Elektron, which already supports Thunderbolt 4 and delivers speeds up to 2,800 MB/s read, but retails at $199.99 for 1TB — $50 more than the V3's 1TB price. SanDisk's aggressive pricing at $149.99 for 1TB with faster specs puts OWC in a difficult position, particularly among Mac-centric creative professionals who have historically been OWC's core audience.
There is also a broader signal here for the NAS and desktop SSD market. The 232-layer 3D TLC NAND that SanDisk is using in the V3 is the same generation appearing in enterprise SSDs from Kioxia and Western Digital's internal product lines. Its appearance in a $149.99 consumer portable drive suggests NAND pricing has dropped enough to make Gen 4 performance economically viable at the mainstream level — a trend that will likely push Samsung, Crucial, and Seagate to accelerate their own next-gen portable announcements before the 2025 holiday season.
Availability and Final Verdict
The SanDisk Extreme Pro Portable SSD V3 goes on sale through SanDisk's website, Amazon, Best Buy, and B&H Photo starting in April 2025. The 1TB model is priced at $149.99, the 2TB at $229.99, and the 4TB at $399.99. All three capacities ship with both a USB-C to USB-C cable (40 Gbps rated) and a USB-C to USB-A adapter in the box.
For creative professionals and power users with Thunderbolt 4 or USB4-equipped machines, the V3 is the most compelling portable SSD announcement since Samsung's T7 Shield redefined durability standards in 2022. The combination of 4,000 MB/s speeds, genuine Thunderbolt 4 support, IP68 durability, and competitive pricing makes it the new default recommendation at this performance tier — at least until Samsung responds with a T10.

In sequential read/write benchmarks: PCIe 5.0 doubles PCIe 4.0 (up to 14,000 MB/s vs 7,000 MB/s). In daily use — loading games, booting OS, opening apps — the difference is imperceptible. PCIe 5.0 drives run hotter and cost more; PCIe 4.0 SSDs remain the best value in 2026.
2 TB is the practical minimum if you play multiple AAA titles (modern games occupy 60–150 GB each). 4 TB provides comfortable headroom for a full game library plus media files. HDDs remain useful secondary storage for archiving, though their speed advantage has narrowed.
For PCIe 5.0 drives: yes, a heatsink prevents thermal throttling. PCIe 4.0 drives run cooler and typically don't need one unless installed in a tight airflow environment. Most modern motherboards include M.2 heatsinks; third-party options add minimal cooling benefit.
The best value pick is typically ranked #3–#5 in our guide — it delivers 85–90% of the top model's performance at 60–70% of the price. Check the comparison table above for side-by-side specs and our value score per dollar.
Upgrade when your current device shows clear performance gaps, fails to receive software/security updates, or physically degrades. In most consumer tech categories, a 3–4 year upgrade cycle provides the best value; enthusiasts may upgrade every 2 years for meaningful improvements.
For full warranty coverage and return protection, buy directly from the manufacturer or authorized retailers (Amazon, Best Buy, B&H Photo). Gray-market deals can save 10–20% but may void manufacturer warranties or carry non-regional firmware. Extended warranties are worth considering for premium devices over $500.
Prime Day (July), Black Friday, and Cyber Monday typically offer 15–30% discounts on major electronics. If you can wait 4–8 weeks and a major sale is approaching, the savings are often significant. Otherwise, buy now — most products don't meaningfully improve mid-cycle.
