# WD Black SN750 2TB NVMe SSD Review (2026)

The WD Black SN750 2 TB pairs a massive 1,200 TBW endurance rating with PCIe 3.0 x4 bandwidth, making it a strong candidate for content creators who need high-capacity sustained write storage.

Quick answer: The WD Black SN750 2 TB is the endurance champion of WD's PCIe 3.0 lineup, with 1,200 TBW and best-in-class sustained write performance. Content creators and professionals who write large files regularly will benefit most from this combination. For pure gaming and everyday desktop responsiveness, the Samsung 970 EVO Plus or the newer PCIe 4.0 WD Black SN850 offer better read-heavy performance. The SN750 2 TB remains a reliable workhorse for write-intensive workflows on PCIe 3.0 platforms.

## Performance

WD rates the 2 TB SN750 for up to 3,400 MB/s sequential reads and 2,900 MB/s sequential writes over PCIe 3.0 x4, with 480,000 random read IOPS and 550,000 random write IOPS. These numbers are slightly below the 1 TB model's peak but remain competitive in the PCIe 3.0 class.

The SN750's tiered SLC write cache scales with capacity, giving the 2 TB model a larger cache than smaller variants. Sustained write performance after cache exhaustion is the SN750's strongest suit -- Tom's Hardware found it among the most consistent sustained writers in the PCIe 3.0 market. This matters for workloads like video editing, data migration, and large file transfers where other drives see sharp performance cliffs.

Gaming Mode in WD Dashboard disables low-power states for marginal latency improvements. Read performance in application benchmarks trails some competitors, which is the SN750's consistent weak spot across all capacities.

## Endurance, TBW & Warranty

WD rates the 2 TB SN750 for 1,200 TBW of write endurance under a five-year limited warranty. At 50 GB of writes per day -- a heavy consumer workload that includes game library management and media creation -- 1,200 TBW translates to roughly 65 years of use. The drive is overprovisioned by approximately 9% and includes tiered SLC caching, thermal throttling, NAND management, and LDPC error correction. WD does not support hardware encryption or secure erase via Parted Magic on the SN750.

## Pros and Cons

**Pros:**

- 1,200 TBW endurance rating
- 3,400 MB/s reads, 2,900 MB/s writes
- Class-leading sustained write performance
- DDR4 DRAM cache
- Single-sided M.2 2280 at 2 TB
- 480K/550K random read/write IOPS
- Five-year warranty
**Cons:**

- Slightly slower than the 1TB model
- Read performance trails Samsung 970 EVO Plus
- No hardware encryption
- No secure erase via Parted Magic
- Superseded by SN850 on PCIe 4.0 platforms


## Verdict

The WD Black SN750 2 TB is the endurance champion of WD's PCIe 3.0 lineup, with 1,200 TBW and best-in-class sustained write performance. Content creators and professionals who write large files regularly will benefit most from this combination. For pure gaming and everyday desktop responsiveness, the Samsung 970 EVO Plus or the newer PCIe 4.0 WD Black SN850 offer better read-heavy performance. The SN750 2 TB remains a reliable workhorse for write-intensive workflows on PCIe 3.0 platforms.

## Frequently Asked Questions

### Is the WD Black SN750 2TB good for gaming?

Yes, with caveats. The SN750 2 TB delivers fast game load times on PCIe 3.0 platforms and its 2 TB capacity can hold dozens of modern AAA titles. However, its read responsiveness in application benchmarks trails competitors like the Samsung 970 EVO Plus. The practical difference in game load times is small -- typically under a second between comparable PCIe 3.0 drives. The 2 TB capacity is more relevant for gaming than raw speed differences.

### What is the TBW endurance of the WD Black SN750 2TB?

The 2 TB SN750 is rated for 1,200 TBW (terabytes written), double the 1 TB model's 600 TBW and six times the 250 GB model's 200 TBW. This is the highest endurance in the SN750 lineup. At 50 GB of writes per day, 1,200 TBW would take approximately 65 years to exhaust, making it more than adequate even for heavy content creation workloads.

### Does the WD Black SN750 2TB have a DRAM cache?

Yes. The SN750 uses an SK Hynix DDR4 DRAM chip for the flash translation layer, across all capacities including 2 TB. This is a full DRAM-based design that contributes to the drive's consistent performance and sustained write throughput.

### How does the WD Black SN750 2TB compare to the Samsung 970 EVO Plus?

The SN750 leads in sustained write performance, maintaining high throughput after the SLC cache fills. The Samsung 970 EVO Plus leads in read-heavy application benchmarks and general responsiveness. Both offer 2 TB capacities with DRAM caches on PCIe 3.0 x4. The Samsung has a more mature feature set including secure erase support. For write-heavy workloads like video editing, the SN750 has the edge; for read-dominated gaming use, the Samsung is slightly faster.

### Is the WD Black SN750 2TB good for video editing?

Yes, and this is the capacity that makes the most sense for that workload. The combination of 1,200 TBW endurance, strong sustained write performance, and 2 TB of capacity makes the SN750 well-suited as a video editing scratch disk or media library. The drive maintains high write throughput even during extended transfers, which is critical when working with 4K footage.

### Is the WD Black SN750 2TB slower than the 1TB model?

Slightly. The 2 TB reads at 3,400 MB/s versus 3,470 MB/s on the 1 TB, and writes at 2,900 MB/s versus 3,000 MB/s. Random IOPS are also marginally lower. The 1 TB model is the peak performer in the SN750 family. However, the 2 TB's larger SLC cache and double the endurance make it the better choice for write-heavy workloads despite the small speed deficit.
