Customer Reviews
Customer Review:
Western Digital is continuing to do what they always do. Excellent products at reasonable prices. I bought this to put into a new PC I bought when I was forced to move to Windows 11. It was a super easy install and setup. It was completely compatible. I had no issues with heat resistance or storage limitations.
Customer Review:
Coming from SN850x, those m.2 were already so fast but this one is almost double the speed, loading window only takes 3s (after initial mobo check). Heat management is not an issue at all unlike Samsung 9100 Pro that runs much hotter and very easy to install and I had no problem with the benchmark files.
2. WD Black SN8100 2TB NVMe SSD with PCIe 5.0, up to 14,900MB/s read, perfect for AI, gaming & video editing
The 2TB version maintains the same incredible PCIe 5.0 performance as its larger cousin, offering excellent value for gamers and creators who need substantial storage without breaking the bank. Perfect balance of capacity and cost.
Key Features That Stand Out
- ✓ Identical PCIe Gen 5.0 performance to 4TB model
- ✓ Sequential read up to 14,900MB/s
- ✓ Great price-to-performance ratio
- ✓ Same power efficiency benefits
Why We Recommend It
If you want the blazing-fast PCIe 5.0 speeds but don’t need the maximum capacity, this 2TB model gives you the best of both worlds. It’s our editor’s choice for most users who want future-proof performance without overspending.
Best For
Gaming builds, creative workstations, and users who need fast storage but can work within a 2TB capacity limit.
Pros and Cons
Pros:
- Same elite performance as 4TB model
- More affordable than larger capacity
- Excellent value proposition
- Proven reliability
Cons:
- Lower capacity may limit use cases
- Still requires PCIe 5.0 support
- Pricier than Gen4 alternatives

This PCIe 4.0 SSD offers incredible performance at a much more accessible price point, delivering up to 7,300MB/s read speeds that still crush most workloads. Great alternative if you don’t have PCIe 5.0 motherboard support.
Key Features That Stand Out
- ✓ PCIe Gen 4.0 interface compatibility
