BIWIN Black Opal (PCIe 4.0 NVMe/5,000 MB/s Read/4,500 MB/s Write/OEM-Turned-Retail Value Drive) Review
The BIWIN Black Opal comes from a manufacturer better known as an OEM supplier, including work for Samsung's own SSD lines, that has more recently started selling drives under its own name to end consumers.
The manufacturing pedigree is real, but as a consumer-facing brand it's still building its own reputation, so treat this as a value pick backed by legitimate NAND and controller experience rather than a brand you already know from the DIY PC space.
Performance and Speed
5,000 MB/s read and 4,500 MB/s write is a mainstream mid-tier Gen 4 result, not chasing flagship numbers but comfortably ahead of anything PCIe 3.0 can offer. It's a sensible speed target for general desktop use, game installs, and everyday file transfers.
OEM Manufacturing Background
BIWIN's manufacturing background as an OEM and ODM supplier, including NAND packaging and module work for larger brands, gives it real technical depth even though the retail brand itself is newer to end consumers. That's a genuinely different risk profile than a brand-new company with no manufacturing history at all.
Comparison to Alternatives
Against the Silicon Power XPOWER XS70, also covered on this site, that drive posts notably higher rated speeds for a moderate price step up, worth it for anyone wanting more headroom. Against the Netac NV7000, also covered on this site, another budget-aggressive Gen 4 option, the two compete closely on both price and positioning.
Who This SSD Is Actually For
Value-focused buyers comfortable with a manufacturing-first brand that's newer to direct retail.
Mainstream desktop use where 5,000 MB/s comfortably covers game loading and everyday transfers.
Not for anyone chasing top-tier Gen 4 speed. Silicon Power's XPOWER XS70, covered elsewhere on this site, delivers meaningfully more bandwidth for a moderate price increase.

- Mainstream desktop use where 5,000 MB/s comfortably covers game loading and everyday transfers.
- Secondary storage drives where top-tier speed isn't the priority.
Not for
