Samsung 9100 Pro 4TB high-capacity Gen5 SSD
The Samsung 9100 Pro 4TB pushes PCIe 5.0 x4 throughput to 14,800 MB/s sequential reads with 2,200,000 random read IOPS, making it the highest-performing capacity in Samsung's Gen5 consumer lineup.
The 4 TB model sits near the top of the 9100 Pro family, offering the highest sequential and random performance in the range along with massive storage capacity. It shares the same Samsung Presto eight-channel PCIe 5.0 controller and 236-layer V-NAND TLC flash as the rest of the lineup, but its larger die count enables better interleaving, raising sequential reads to 14,800 MB/s and random reads to 2,200,000 IOPS.
The 4 TB capacity includes a 4 GB LPDDR4X DRAM chip for the flash translation layer, double the 2 TB model's allocation. Endurance scales to 2,400 TBW, enough for 1.3 TB of daily writes over the five-year warranty period. This makes the 4 TB model suitable for content creators working with 4K and 8K video, large dataset processing, or game development environments with many concurrent projects.
The 9100 Pro competes with the Crucial T705 4TB and the Sabrent Rocket 5 4TB in the high-capacity PCIe 5.0 space. It also serves as an alternative to the Samsung 870 QVO 4TB or 8TB SATA SSDs for users who need both speed and bulk storage. The drive requires a PCIe 5.0 x4 M.2 slot for full performance, though it is backward compatible with PCIe 4.0 systems at reduced speeds around 7,000 MB/s. The single-sided M.2 2280 design ensures broad compatibility with both desktop and laptop M.2 slots.

🚀 Performance and benchmarks
Samsung rates the 9100 Pro 4TB at 14,800 MB/s sequential read and 13,400 MB/s sequential write, the fastest read speed in the 9100 Pro lineup. Random performance reaches 2,200,000 read IOPS and 2,600,000 write IOPS at QD256, matching the write IOPS of all capacities while exceeding the read IOPS of the 1 TB and 2 TB models by roughly 19 percent.

- PNY XLR8 CS3250 4 TB: 14,900 MB/s read, 13,500 MB/s write
- Samsung 9100 Pro 4 TB (this drive): 14,800 MB/s read, 13,400 MB/s write
- Samsung 9100 Pro 1 TB: 14,700 MB/s read, 13,300 MB/s write
- Samsung 9100 Pro 2 TB: 14,700 MB/s read, 13,400 MB/s write
- Samsung PM9E1 1 TB: 14,500 MB/s read, 12,600 MB/s write
The 4 TB model uses twice as many NAND die as the 2 TB version, which improves parallelism across the eight Presto controller channels. This extra interleaving is the reason the 4 TB drive gains 100 MB/s on sequential reads and 350,000 on random read IOPS compared to the smaller capacities. Sustained writes remain consistent thanks to Samsung's TurboWrite SLC caching, though heavy continuous writes beyond the cache size will fall to native TLC speeds.
Active power consumption is around 8.1 W for reads, making thermal management straightforward with a motherboard M.2 heatsink. The 4 TB model is a single-sided M.2 2280 design, so it fits standard laptop and desktop slots without clearance issues.
🖥️ Endurance and warranty
Samsung backs the 9100 Pro 4TB with a five-year limited warranty and a 2,400 TBW endurance rating. Writing 2,400 TB over five years works out to approximately 1.3 TB per day. Even demanding video editing workflows writing 100 GB daily would use only about eight percent of the rated endurance over the warranty period. For typical consumer use at 20 to 50 GB per day, the drive would theoretically last well over 100 years at its rated endurance. Samsung Magician software provides real-time TBW tracking, drive health monitoring, and firmware update notifications to keep the drive running optimally.

Conclusion
The Samsung 9100 Pro 4TB is the pick for users who need both speed and capacity without compromise. Its 14,800 MB/s reads, 2,200K random read IOPS, and 2,400 TBW endurance make it the strongest performer in the 9100 Pro family. Content creators, game developers, and workstation builders who regularly move hundreds of gigabytes will benefit from the capacity and endurance headroom. Users who do not need 4 TB should look at the 2 TB model, which offers nearly identical performance at a lower cost per drive. For bulk archival storage where speed is secondary, a SATA SSD or HDD remains more cost-effective.
