Buying Recommendations
| User Profile | Best Choice | Rationale |
| Extreme Content Creator/AI Developer | 9100 Pro | You move/save massive multi-GB files daily. The sequential write speed and high random IOPS are essential for 8K video and AI model processing. |
| High-End Gamer (Current Gen4) | 990 Pro | The 9100 Pro’s massive sequential speed offers minimal tangible benefit for current gaming loads. Save money and put it toward a GPU or higher-capacity 990 Pro. |
| New System Builder (PCIe 5.0 Ready) | 9100 Pro | If your motherboard supports PCIe 5.0 and you can justify the premium, choosing the 9100 Pro future-proofs your build and maximizes your motherboard’s potential. |
| PS5 User | 990 Pro (with Heatsink) | The 9100 Pro is not currently certified or recommended for the PS5. The 990 Pro with a heatsink is the proven, top-tier choice for the console. |
| Budget-Conscious Power User | 990 Pro | The performance gain for general use and even 4K editing doesn’t warrant the significant price difference. Opt for a 4TB 990 Pro for better overall value and capacity. |
