Storage costs have reached a breaking point, with Western Digital’s WD Black SN7100 and SN8100 SSDs now commanding prices that rival high-end GPUs. The SN8100 1TB, a PCIe 5.0 drive, has jumped to $366, while the 8TB variant—once a niche luxury—now costs nearly $3,000, making it one of the most expensive single components in a modern PC.
The price escalation extends across the lineup. The SN7100 1TB, a PCIe 4.0 model, sits at $247, while the 500GB SN7100 starts at $134. Even mid-range capacities like the SN8100 4TB ($1,460) and SN7100 2TB ($492) reflect the broader trend: high-capacity NVMe SSDs are no longer budget-friendly.
Why the sudden spike?
Industry analysts point to a perfect storm of supply constraints, rising NAND flash costs, and reduced production from major manufacturers like Samsung and SK Hynix. What was once a $100–$200 investment for a 1TB PCIe 4.0 SSD now requires nearly $400—a 300% increase in just months. The gap between PCIe 4.0 and 5.0 models has widened, too, with the SN8100 1TB costing $119 more than the SN7100 equivalent.
For most users, the performance difference between PCIe 4.0 and 5.0 is minimal in real-world workloads. Yet the price premium forces buyers to weigh whether the extra speed justifies the cost—especially when an 8TB SN8100 now exceeds the price of a GeForce RTX 5090 GPU.
Who’s hit hardest?
Professionals relying on large datasets, 4K video editors, and high-end workstations face the steepest impact. An 8TB SSD—once a practical choice for raw storage—now requires a budget equivalent to a mid-range graphics card. Even gamers storing multiple high-resolution games or creators managing large media libraries are feeling the pinch.
The surge also raises questions about long-term affordability. With NAND manufacturers planning further price hikes this quarter, the trend shows no signs of reversing. For now, buyers must decide whether to invest in capacity or allocate funds elsewhere in their builds.
Key specs and pricing
- SN8100 (PCIe 5.0):
- 1TB – $366
- 2TB – $732
- 4TB – $1,460
- 8TB – $2,920

The SN8100 series, with its PCIe 5.0 interface, delivers faster sequential speeds (up to 10,000 MB/s read, 9,000 MB/s write) compared to the SN7100’s PCIe 4.0 (7,300 MB/s read, 6,600 MB/s write). However, the real-world impact for most users remains modest, given that PCIe 4.0 SSDs still outperform SATA drives by a significant margin.
For those needing high capacity, the choice becomes stark: pay a premium for PCIe 5.0 or opt for PCIe 4.0 and save hundreds. The 8TB SN8100, in particular, now sits at a crossroads—useful for enterprise or extreme storage needs, but prohibitively expensive for casual users.
Availability remains limited to Western Digital’s official Japanese store, though third-party retailers may follow suit. Buyers should expect further adjustments as market conditions evolve.
