# Smartbuy Impact E16 2TB SSD — In-Depth Review & Specs (2026)

The Smartbuy Impact E16 2TB is the largest-capacity member of Smartbuy's first-generation PCIe 4.0 family. Like its 500GB and 1TB siblings, it is built on the Phison PS5016-E16 reference platform — an 8-channel, 28nm controller paired with Kioxia 96-layer TLC NAND and a DDR4 DRAM buffer. With 2 TB of capacity, 5,000 MB/s sequential reads, and 4,400 MB/s writes, it serves as a spacious Gen4 workhorse for gaming, content creation, and bulk storage on the Russian and CIS markets.

Quick answer: The Smartbuy Impact E16 2TB is a straightforward, no-surprises storage workhorse. It does not chase benchmark records — the aging 28nm E16 controller was never going to — but it delivers exactly what the Phison reference design promises: 5,000 MB/s reads, consistent real-world responsiveness thanks to the 2 GB DRAM buffer, and enough capacity to serve as your one and only NVMe drive. The 2,500 TBW endurance rating, while lower than some Western-branded E16 2TB drives, is still far beyond any realistic consumer write load. The question, as always with Smartbuy, is availability and pricing outside Russia. If you can buy one at a meaningful discount versus a modern DRAM-less Gen4 2TB drive, it is a perfectly serviceable choice. At equal pricing, look to newer alternatives with better efficiency and longer warranties.

## Performance

Sequential throughput is the standard E16 fare: 5,000 MB/s read and 4,400 MB/s write in synthetic benchmarks like CrystalDiskMark. In real-world large-file copies on a PCIe 4.0 platform, expect roughly 4,700–4,800 MB/s read and 4,000–4,200 MB/s write. The extra NAND dies in the 2TB model give it an edge in sustained write scenarios — the SLC cache can be several hundred gigabytes deep, meaning most real-world write bursts never leave the fast cached zone.

Random performance at 750,000 IOPS read and write is identical to the 1TB model on paper, but in practice the 2TB version handles mixed random workloads with slightly lower tail latency thanks to the larger over-provisioning pool and extra die-level parallelism. Gaming performance is indistinguishable from any other Gen4 SSD — games simply cannot saturate 5,000 MB/s of sequential reads, so load times are bottlenecked by the CPU and game engine, not the drive. Temperature under sustained load settles around 65–72°C with the stock graphene spreader in a desktop with moderate airflow. Peak power consumption is about 6.5 W, with idle power under 1 W.

## Endurance, TBW & Warranty

Smartbuy provides a 3-year limited warranty on SSD products sold through authorized Russian and CIS distributors. The warranty is capped at 2,500 TBW — exceeding this write volume voids coverage regardless of the time elapsed. International buyers should confirm warranty support with the seller, as Smartbuy's warranty infrastructure is primarily designed for the Russian and CIS retail channel.

## Pros and Cons

**Pros:**

- 2 TB capacity — enough for a full game library and media collection
- 5,000 MB/s reads with DDR4 DRAM for consistent latency
- Single-sided M.2 2280 fits any PCIe 4.0 laptop or desktop
- Kioxia 96L TLC NAND from an industry-leading flash manufacturer
- Deep SLC write cache handles large sequential writes gracefully
**Cons:**

- 28nm E16 controller is dated — half the speed of modern Gen4 flagships
- 2,500 TBW endurance is lower than many Western E16 2TB competitors
- No hardware encryption
- Limited availability and warranty support outside CIS countries
- Graphene heat spreader is adequate but not great for sustained workloads


## Verdict

The Smartbuy Impact E16 2TB is a straightforward, no-surprises storage workhorse. It does not chase benchmark records — the aging 28nm E16 controller was never going to — but it delivers exactly what the Phison reference design promises: 5,000 MB/s reads, consistent real-world responsiveness thanks to the 2 GB DRAM buffer, and enough capacity to serve as your one and only NVMe drive. The 2,500 TBW endurance rating, while lower than some Western-branded E16 2TB drives, is still far beyond any realistic consumer write load. The question, as always with Smartbuy, is availability and pricing outside Russia. If you can buy one at a meaningful discount versus a modern DRAM-less Gen4 2TB drive, it is a perfectly serviceable choice. At equal pricing, look to newer alternatives with better efficiency and longer warranties.

## Frequently Asked Questions

### Is the 2TB Impact E16 double-sided?

No. The Smartbuy Impact E16 2TB is a single-sided M.2 2280 drive, thanks to the high-density Kioxia 96L TLC NAND packages that allow 2 TB of flash on one side of the PCB. This ensures compatibility with thin laptops that cannot accommodate double-sided drives.

### Can I use this as my only drive?

Yes — 2 TB is enough for Windows or Linux, a full suite of applications, a substantial Steam library, and a media collection. The read and write speeds are more than sufficient for a primary OS drive. The only scenario where you might want a faster secondary drive is if you regularly move multi-hundred-gigabyte video projects.

### How does it compare to a Samsung 980 PRO 2TB?

The Samsung 980 PRO 2TB uses Samsung's in-house Elpis controller and V-NAND, delivering up to 7,000/5,100 MB/s — a clear step above the 5,000/4,400 MB/s of the Impact E16. The 980 PRO also carries a 5-year warranty with 1,200 TBW endurance (lower TBW but longer warranty period). The Samsung is objectively the better drive, but the Impact E16 may be significantly cheaper in the Russian market.

### Does the 2TB model have more DRAM than the 1TB?

Yes. The 2TB Impact E16 includes 2 GB of DDR4 DRAM, compared to 1 GB on the 1TB model and 512 MB on the 500GB model. The DRAM primarily caches the flash translation layer mapping table, which scales with capacity.

### What PCIe generation does this drive use?

The Phison PS5016-E16 controller supports PCIe 4.0 x4 with the NVMe 1.3 protocol. The drive is backward-compatible with PCIe 3.0 slots, though performance will be limited to roughly 3,500 MB/s in that configuration.
