Samsung 9100 Pro 1TB PCIe 5.0 SSD tested
The Samsung 9100 Pro 1TB is Samsung's first PCIe 5.0 x4 consumer SSD, pairing the in-house Presto controller with eighth-generation 236-layer V-NAND to hit 14,700 MB/s sequential reads.
The 9100 Pro marks Samsung's entry into the PCIe 5.0 x4 consumer market. The drive uses Samsung's Presto controller, an eight-channel design built for the NVMe 2.0 protocol, paired with eighth-generation 236-layer V-NAND TLC flash. A dedicated LPDDR4X DRAM chip provides 1 GB of mapping cache per terabyte of capacity, so the 1 TB model carries a single 1 GB IC on board.
This is the smallest capacity in the 9100 Pro family, which spans 1 TB, 2 TB, 4 TB, and 8 TB variants. The 1 TB model sits at the bottom of the sequential-speed ladder: its 14,700 MB/s read and 13,300 MB/s write ratings trail the 2 TB and larger drives by a small margin. Random performance is also slightly lower, with 1,850,000 read IOPS versus 2,200,000 on the higher capacities. The 1 TB model still carries a 600 TBW endurance rating and a five-year warranty.
Compatibility is straightforward: any motherboard with an M.2 2280 slot and PCIe 5.0 x4 lanes will run the drive at full speed, while PCIe 4.0 systems cap sequential throughput at roughly 7,000 MB/s. The 9100 Pro competes directly with the Crucial T705, WD Black SN850X (PCIe 4.0), and the Kingston Fury Renegade G5. For PS5 expansion the drive fits Sony's requirements (PCIe 4.0 NVMe, 5,500 MB/s+ read, under 110 x 25 x 11.25 mm with heatsink), though you will need to add a heatsink since Samsung sells it bare.
✅ Storage Comparisons:
🚀 Performance and benchmarks
Samsung rates the 9100 Pro 1TB at 14,700 MB/s sequential read and 13,300 MB/s sequential write over PCIe 5.0 x4. These figures apply to sustained, queued transfers at high queue depths. Random performance comes in at up to 1,850,000 read IOPS and 2,600,000 write IOPS measured at QD256 with 32 threads.

- PNY XLR8 CS3250 4 TB: 14,900 MB/s read, 13,500 MB/s write
- Samsung 9100 Pro 1 TB (this drive): 14,700 MB/s read, 13,300 MB/s write
- Samsung PM9E1 OEM AI Optimized M.2 2242 1 TB: 14,500 MB/s read, 12,600 MB/s write
- Samsung PM9E1 OEM AI Optimized M.2 2242 2 TB: 14,500 MB/s read, 12,600 MB/s write
- Samsung PM9E1 OEM AI Optimized M.2 2242 4 TB: 14,500 MB/s read, 12,600 MB/s write
The 1 TB model uses fewer NAND die packages than the 2 TB and 4 TB variants, which limits interleaving and accounts for the modest gap in sequential write speed (13,300 vs 13,400 MB/s) and random read IOPS (1,850K vs 2,200K). In real-world workloads the difference is small, but heavy parallel write scenarios may show a measurable gap.
Burst transfers benefit from Samsung's TurboWrite SLC caching layer, which allocates a portion of the TLC array as pseudo-SLC for fast incoming writes. Once the cache fills, writes drop to native TLC speeds. The LPDDR4X DRAM cache holds the full flash translation layer, avoiding the HMB overhead that DRAM-less drives incur. Power draw sits around 8 W active, making the drive one of the cooler-running PCIe 5.0 options available.
🖥️ Endurance and warranty
Samsung covers the 9100 Pro 1TB with a five-year limited warranty. The 1 TB model carries a 600 TBW endurance rating, meaning Samsung guarantees the drive for 600 terabytes of total data written before the warranty expires. To exhaust 600 TBW in five years you would need to write roughly 330 GB per day every day, a workload far beyond typical consumer or gaming use. Most users writing 20 to 50 GB per day would use less than ten percent of the rated endurance over the warranty period. Samsung's Magician software tracks TBW consumption in real time so you can monitor remaining write budget and plan for replacement well before any threshold is reached.

Conclusion
The Samsung 9100 Pro 1TB is a capable PCIe 5.0 drive for users building on a current-gen platform who want top-tier sequential speeds. Its 14,700 MB/s reads and LPDDR4X DRAM cache deliver consistent performance under heavy workloads. The 1 TB capacity limits write endurance to 600 TBW and random IOPS trail the larger capacities, so content creators working with massive files may prefer the 2 TB or 4 TB models. Competitors like the Crucial T705 1TB offer similar PCIe 5.0 throughput at a lower price. For PCIe 4.0-only systems, the Samsung 990 Pro remains a strong alternative at lower power draw.
