Samsung’s PCIe Gen 5 flagship SSD has dropped to its best price since launch, with the Samsung 9100 Pro 2TB SSD down to $350 (was $680) at Amazon right now. For UK readers, the 9100 Pro 2TB drops to £304 (was £529) for Prime Day, too.
This is Samsung’s fastest consumer drive ever, and in our review, we said "it definitely delivers fantastic performance with the fastest write speeds I've ever tested." If you’re building or upgrading a system and want the best storage performance available right now without compromise, this is the drive.
The 9100 Pro capably offers best-in-class sequential read and write performance and impressive random read/write speeds. For anyone upgrading from a PCIe Gen 4 drive, the difference in large-file transfers and sustained read workloads is immediately apparent. But what really catches my eye is that it's 49% off for Prime Day right now.

More interestingly for business and creative users, we clocked that while we didn't quite hit the promised highs of 14,700MB/s sequential read speeds, it still offered blazing-fast speeds, particularly shining in its sequential write performance, making it a fantastic pick for professionals.
The 9100 Pro is Samsung’s first fully PCIe Gen 5 x4 consumer drive — a meaningful distinction from the 990 EVO, which used a hybrid Gen 4 x4 / Gen 5 x2 interface as a halfway measure. Full Gen 5 x4 doubles the available interface bandwidth over Gen 4, and at 14,700MB/s sequential reads, the 9100 Pro delivers on that headroom. For context, a high-end Gen 4 drive like the Samsung 990 Pro tops out at around 7,450MB/s reads — the 9100 Pro is almost exactly twice as fast at the interface level.

The 2TB capacity is the sweet spot in the line-up. It’s single-sided — meaning all components sit on one face of the PCB — which makes it compatible with a wider range of laptops and slim-profile systems that can’t accommodate double-sided drives. The 2TB model is also rated slightly faster than the 1TB model on sequential reads (14,700 MB/s vs 13,300 MB/s), and its 1,200 TBW endurance rating is generous for a consumer drive at this capacity.
The LPDDR4X DRAM cache (2GB at 2TB) is a meaningful inclusion that differentiates it from DRAM-less budget Gen 5 drives. DRAM cache significantly improves random I/O consistency — particularly relevant for workstation use cases involving large databases, virtual machines, or AI inference workloads where latency matters as much as peak throughput.
