# Samsung 9100 Pro 1TB PCIe 5.0 SSD tested (2026)

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.

Quick answer: 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.

## Performance

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.

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, TBW & 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.

## Pros and Cons

**Pros:**

- 14,700 MB/s sequential read speed
- LPDDR4X DRAM for FTL mapping
- Samsung Presto in-house controller
- 236-layer V-NAND with good density
- Five-year warranty with 600 TBW
- Low active power draw for PCIe 5.0
**Cons:**

- Requires PCIe 5.0 for full speed
- 1TB has lower IOPS than 2TB+ models
- No included heatsink
- High power vs PCIe 4.0 alternatives
- 600 TBW lower than 2TB model


## Verdict

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.

## Frequently Asked Questions

### Is the Samsung 9100 Pro 1TB compatible with PS5?

Yes, the 9100 Pro meets Sony's PS5 expansion requirements: it is a PCIe 4.0-capable NVMe drive that exceeds the 5,500 MB/s minimum read speed, and the bare drive measures well within the 110 x 25 x 11.25 mm slot limit. You will need to add a compatible heatsink since Samsung does not include one with the base model. Once installed, the drive will operate at PCIe 4.0 speeds which still far exceed the PS5 minimum threshold.

### Does the Samsung 9100 Pro 1TB have DRAM cache?

Yes. The 9100 Pro uses a dedicated LPDDR4X DRAM chip sized at 1 GB per terabyte of storage. The 1 TB model therefore includes a 1 GB LPDDR4X IC for the flash translation layer. This is a significant advantage over DRAM-less drives that rely on Host Memory Buffer and borrow system RAM.

### What controller does the Samsung 9100 Pro use?

The 9100 Pro uses Samsung's in-house Presto controller, an eight-channel NVMe 2.0 design built on a 5 nm process. It is Samsung's first controller purpose-built for PCIe 5.0 x4 consumer SSDs. The Presto controller manages the 236-layer V-NAND TLC flash and LPDDR4X DRAM cache to deliver up to 14,700 MB/s sequential read throughput on the 1 TB model.

### How fast is the Samsung 9100 Pro 1TB on PCIe 4.0?

On a PCIe 4.0 x4 platform the 9100 Pro is capped by the bus bandwidth, topping out at roughly 7,000 to 7,300 MB/s sequential read. This is still fast by PCIe 4.0 standards, comparable to drives like the Samsung 990 Pro. For full 14,700 MB/s reads you need a motherboard or CPU with PCIe 5.0 x4 M.2 slot support.

### What is the TBW endurance of the Samsung 9100 Pro 1TB?

The 1 TB model is rated at 600 TBW (terabytes written). This means Samsung guarantees the drive for up to 600 terabytes of total host writes over the warranty period. At an average of 50 GB of writes per day, the drive would last over 32 years before exhausting its rated endurance, well beyond the five-year warranty term. Samsung Magician software lets you check your current TBW consumption at any time.

### Does the Samsung 9100 Pro 1TB run hot?

The 9100 Pro is one of the more power-efficient PCIe 5.0 drives available, with active power draw around 8 W. It still generates more heat than PCIe 4.0 drives, so a motherboard with an M.2 heatsink is recommended for sustained workloads. Samsung also sells a heatsink version for systems that lack integrated M.2 cooling solutions.
