The Samsung 9100 PRO SSD is a pretty big jump in storage performance, surpassing previous consumer SSDs like the 990 EVO and EVO Plus in nearly every metric. While the 990 EVO and EVO Plus were developed to meet the needs of mainstream users looking for a balance of performance and affordability, the 9100 PRO is engineered specifically for professionals, power users, and high-performance computing environments. One of the most significant differences is the interface upgrade, with the 9100 PRO utilizing PCIe 5.0 x4—a major step up from the 990 EVO’s PCIe 4.0 and the EVO Plus’s PCIe 3.0. This translates to dramatically higher sequential read and write speeds, where the 9100 PRO reaches up to 14,800 MB/s read and 13,400 MB/s write speeds, whereas the 990 EVO maxes out at 5,000 MB/s read and 4,800 MB/s write, and the EVO Plus is limited to 3,500 MB/s read and 3,200 MB/s write. These figures alone make the 9100 PRO nearly three times faster than the EVO Plus and close to three times faster than the 990 EVO, delivering unprecedented speed for workloads like 8K video editing, AI processing, and high-resolution content creation.
Beyond raw speed, the 9100 PRO also dominates in efficiency, endurance, and storage capacity, areas where Samsung has significantly improved upon its previous SSD lineup. The 9100 PRO features an endurance rating of up to 4,800 TBW (Total Bytes Written) for the 8TB model, whereas the 990 EVO and EVO Plus are capped at 600 TBW, meaning the 9100 PRO can handle up to eight times the write cycles before reaching its lifespan limit. This enhanced durability makes it ideal for workstations and AI applications where large datasets are continuously processed and rewritten. Furthermore, Samsung has introduced an 8TB model in the 9100 PRO lineup, a first for its consumer NVMe SSDs, whereas the 990 EVO is limited to 4TB and the EVO Plus maxes out at 2TB. Power efficiency has also been improved by up to 49%, thanks to the 5nm controller used in the 9100 PRO, allowing it to maintain higher performance while consuming less power per operation. These advancements make the 9100 PRO not just an incremental upgrade but a transformative SSD in Samsung’s lineup, aimed squarely at professionals who demand uncompromising speed, reliability, and storage capacity.

The 9100 PRO Series introduces Samsung’s Intelligent TurboWrite 2.0, a highly optimized SLC caching system that significantly improves write speeds and overall performance consistency. amsung TurboWrite is a technology used in Samsung SSDs to make them faster. Think of it like a temporary speed boost for writing data.
Faster file transfers (especially for small/medium-sized files). Better everyday performance (like booting Windows, opening apps, or saving documents). Slows down for big files – If you copy very large files that fill up the TurboWrite cache, the speed drops to the SSD’s normal (slower) write speed.
Unlike conventional SSDs, which experience a performance drop once the primary cache is exhausted, TurboWrite dynamically allocates NAND capacity as an extended cache, maintaining peak speeds for longer durations. The cache size is based on drive capacity, with 114GB allocated for 1TB models, 226GB for 2TB, and up to 442GB for 4TB variants. This feature ensures high-speed data transfers and minimizes write slowdowns, especially beneficial for video editors, software developers, and content creators working with large datasets.
The Samsung 9100 PRO is designed with long-term endurance in mind, featuring Total Bytes Written (TBW) ratings of up to 4,800TB for the 8TB variant. This translates to 0.328 Drive Writes Per Day (DWPD), meaning users can rewrite roughly one-third of the drive’s full capacity daily for five years without exceeding its rated lifespan. This makes it ideal for sustained workloads, AI processing, and enterprise environments that require consistent, high-speed storage. Compared to previous-generation SSDs, the 9100 PRO offers significantly improved durability, reducing the risk of performance degradation over time.
The Samsung 9100 PRO SSD will launch in March 2025 with the following pricing:
The heatsink versions will be available for $20 more per model. Given its groundbreaking performance, improved efficiency, and increased storage capacity, the 9100 PRO is set to become one of the leading PCIe 5.0 SSDs in the market, competing with Seagate’s FireCuda 540 and Crucial’s T700.
