What reviewers say about the SanDisk Extreme PRO Portable SSD (USB4)
Four whitelisted testers (StorageReview, Tom's Hardware, TechRadar, PCWorld) hands-on benchmarked the 2TB model. Verdict: fast, premium, and rugged with reads that leave USB 3.2 drives well behind, but sustained and single-thread writes lag cheaper rivals like Corsair's EX400U, and it runs pricey and bulky. Non-whitelist outlets were excluded.

Where reviewers disagree Testers split on value: PCWorld calls it 'decently affordable for USB4' and says 'price is not an issue,' whereas Tom's Hardware ('hard to recommend') and TechRadar ('47% more expensive than the EX400U') judge it overpriced against Corsair's cheaper, faster drive.
The sources (4)
Blackmagic read: 3,172.3 MB/s · Blackmagic write: 2,863.6 MB/s · IOMeter 1-thread seq read: 2,993 MB/s · IOMeter 1-thread seq write: 2,309 MB/s · IOMeter 1-thread random 4K write: 4,959 IOPS · IOMeter 4-thread seq write: 3,497 MB/s · PCMark 10 Storage score: 2,585 · 3DMark Storage score: 1,370
It consistently outperforms USB 3.2 Gen 2×2 drives in sequential and large-block transfers, delivering real-world speeds close to its advertised specs.
we saw relatively weak 4K random write speeds across both IOMeter workloads, and modest performance in game-related tasks like installs and saves during the 3DMark test.
it's very bulky for a modern portable drive and may be less convenient for users who prioritize ultra-compact gear.
Weight: 172.37 g · Sustained write peak: ~3,500 MB/s · Sustained top-speed duration before drop: ~3 minutes · Sustained write after cache saturates: ~1,100 MB/s · Sustained write late-test floor: ~800 MB/s
the drive looks and feels premium, arguably more so than any drive I've tested in years.
it costs substantially more than both the Corsair and LaCie USB4 drives we've tested recently, while often falling behind them in real-world writes.
it's not the best performer among recent drives we've tested, especially when it comes to the kind of sustained writes that are often key for pro users.
CrystalDiskMark 8 read: 3,810 MB/s · CrystalDiskMark 8 write: 3,662 MB/s · CrystalDiskMark 8 real-world write: 2,149 MB/s · AJA 64GB read: 3,363 MB/s · AJA 64GB write: 3,189 MB/s · ATTO read: 3,530 MB/s · ATTO write: 3,380 MB/s · PCMark Data Drive score: 2,992
overall, this drive is excellent, even if it is outperformed by the Corsair drive in some tests.
That's disturbingly 47% more expensive than the EX400U in the USA.
Physically, this is easily one of the larger external SSDs I've seen, even making the chunky SanDisk PRO-G40 seem modest by comparison.
Single-queue/thread 4K write: 40 MB/s · Write speed off secondary cache: 550 MB/s · Link speed on Intel TB4 ports (pre-BIOS fix): 10 Gbps / 5 Gbps
I love the rugged, handsome design and relative affordability.
even when connected at 40Gbps, it was slightly slower than the competition.
