The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the 8TB SanDisk Extreme is the go-to when sheer capacity matters, with cubed3 awarding it 9/10 and calling it a blend of massive capacity, NVMe speed and rugged resilience, and a high-trust Best Buy listing confirming up to 1,050MB/s. r/DataHoarder discussion of the underlying ASM2464-based enclosure notes it can use nearly the full bus speed but the controller chip gets fairly hot under sustained use. The important counterweight is brand-level sentiment: r/videography and r/editors threads repeatedly warn about SanDisk Extreme-family drives failing, so reviewers stress treating this as one copy of your data, never the only copy.
What reviewers liked
- cubed3 9/10 review and Best Buy listing back its capacity and speed
- Up to 8TB in a pocketable IP65 rugged enclosure
- NVMe-class ~1,050MB/s sustained performance for the capacity tier
Where it falls short
- Brand-wide SanDisk Extreme failure reports flagged across r/videography and r/editors
- r/DataHoarder notes the controller can run hot under sustained load
- Amazon rating is pooled across a shared 90,000+ review listing, muddying the signal
