# BIWIN Black Opal X570 Pro 2TB — The Gen5 Sweet Spot (2026)

The BIWIN Black Opal X570 Pro 2TB is a PCIe 5.0 NVMe SSD combining Silicon Motion's SM2508 controller, 2GB of LPDDR4 DRAM, and Micron 232-layer TLC NAND to hit 14,000 MB/s sequential reads and 13,000 MB/s writes in a single-sided M.2 2280 package.

Quick answer: The BIWIN Black Opal X570 Pro 2TB is the strongest value point in the X570 Pro lineup for buyers who do any sustained sequential write work. The step from 1TB to 2TB brings 13,000 MB/s writes (up from 10,500 MB/s), 2,000K read IOPS (up from 1,600K), 2GB of LPDDR4 DRAM (double the 1TB), and a 1,500 TBW endurance rating — all in the same compact single-sided M.2 2280 package that fits PS5 and thin laptops. KitGuru's 8.5 score for the 2TB review reflects a drive that delivers on its rated specifications with good thermal behaviour from the SM2508's 6nm process and the integrated graphene thermal film.

## Performance

The BIWIN Black Opal X570 Pro 2TB is rated at 14,000 MB/s sequential reads and 13,000 MB/s sequential writes on PCIe 5.0 x4. The 13,000 MB/s write figure is the same as the 4TB model and represents a significant jump over the 1TB's 10,500 MB/s, explained by the additional NAND die parallelism available at 2TB. More die running simultaneously both raises the maximum write bandwidth and expands the pSLC (pseudo-SLC) write cache, so the drive sustains its peak write speed across larger data bursts before dropping to native TLC write rates.

For random access, BIWIN rates the 2TB at 2,000,000 read IOPS and 1,600,000 write IOPS. The 2,000K read IOPS rating is 25% higher than the 1TB model's 1,600K figure, again reflecting the greater die parallelism. KitGuru's benchmarking confirmed performance close to rated specifications and recorded thermal peaks in the low-60°C range without an external heatsink — comfortably within safe operating margins for sustained workloads.

In practical terms, the 14,000 MB/s sequential read speed is roughly double the bandwidth of the fastest PCIe 4.0 x4 drives. For DirectStorage-enabled games and video editing timelines that pull large sequential reads from the drive, the Gen5 headroom is directly useful. The 13,000 MB/s write speed means large captures, disk images, and backup jobs complete noticeably faster than on a PCIe 4.0 drive or the 1TB model of the same drive. For general OS and application use, the advantage narrows relative to well-tuned Gen4 options — random 4K latency and OS overhead dominate that workload profile, not peak sequential bandwidth.

## Endurance, TBW & Warranty

BIWIN backs the Black Opal X570 Pro 2TB with a 5-year limited warranty and an endurance rating of 1,500 TBW — the total write volume covered before the endurance warranty clause applies. At a typical desktop write workload of 30 GB per day, 1,500 TBW represents approximately 137 years of use before the endurance budget is exhausted. At a heavier 100 GB per day write rate — common in content creation workflows — the drive would reach its rated limit in over 40 years. Even for video editors writing 300 GB per day, the 1,500 TBW budget provides a 13-year horizon, which is well beyond the practical replacement cycle for any consumer SSD. The 5-year warranty will almost certainly expire before the TBW figure becomes relevant for the vast majority of buyers. Warranty service is handled through BIWIN's support process; buyers in Western markets should confirm regional warranty availability before purchasing through import or grey-market channels, as BIWIN's retail presence outside Asia is still developing.

## Pros and Cons

**Pros:**

- 13,000 MB/s sequential writes — matches the 4TB model and outpaces the 1TB by 24%
- 2,000,000 random read IOPS on 2GB LPDDR4 DRAM
- Silicon Motion SM2508 (6nm) runs cooler than Phison E26 (12nm) rivals
- Single-sided M.2 2280 at 2.50 mm — PS5 and slim-laptop compatible
- 5-year warranty with 1,500 TBW endurance
- Micron 232-layer TLC NAND with graphene thermal film
- PCIe 4.0 and 3.0 backward compatible
**Cons:**

- BIWIN has limited retail presence and RMA infrastructure in Western markets
- No bundled heatsink — relies on graphene film and motherboard thermal padding
- Smaller independent benchmark library than Crucial T705 or Corsair MP700 Pro
- Regional warranty support may be uncertain for grey-market or import purchases
- Gen5 sequential bandwidth advantage is marginal for typical OS and gaming workloads


## Verdict

The BIWIN Black Opal X570 Pro 2TB is the strongest value point in the X570 Pro lineup for buyers who do any sustained sequential write work. The step from 1TB to 2TB brings 13,000 MB/s writes (up from 10,500 MB/s), 2,000K read IOPS (up from 1,600K), 2GB of LPDDR4 DRAM (double the 1TB), and a 1,500 TBW endurance rating — all in the same compact single-sided M.2 2280 package that fits PS5 and thin laptops. KitGuru's 8.5 score for the 2TB review reflects a drive that delivers on its rated specifications with good thermal behaviour from the SM2508's 6nm process and the integrated graphene thermal film.

The caveats are consistent with the rest of the lineup: BIWIN's brand recognition and retail infrastructure in Western markets trail Samsung, WD, and Crucial, and the independent review library is smaller than established Gen5 options. For buyers who are comfortable with a Chinese manufacturer expanding into branded retail and who purchase through a channel with a clear regional warranty, the X570 Pro 2TB is a technically sound and competitively priced PCIe 5.0 drive. For buyers who prioritise established brand support and an extensive RMA track record, the Crucial T705 2TB remains the safer default.

## Frequently Asked Questions

### What are the key specs of the BIWIN Black Opal X570 Pro 2TB?

The 2TB model uses the Silicon Motion SM2508 controller (8-channel, 6nm) with 2GB of LPDDR4 DRAM and Micron 232-layer 3D TLC NAND. It is rated at 14,000 MB/s sequential reads, 13,000 MB/s sequential writes, 2,000,000 random read IOPS, and 1,600,000 random write IOPS on a PCIe Gen5 x4 (NVMe 2.0) interface. Endurance is 1,500 TBW with a 5-year warranty. The drive ships as M.2 2280 single-sided at 2.50 mm height.

### Why is the 2TB write speed higher than the 1TB model?

The 2TB Black Opal X570 Pro is rated at 13,000 MB/s sequential writes versus 10,500 MB/s for the 1TB. This difference comes from NAND die parallelism: the 2TB model populates more NAND die, allowing more simultaneous write operations and a larger pSLC (pseudo-SLC) write cache. More die means higher sustained write bandwidth and a longer cache window before the controller must fall back to native TLC write rates. The sequential read speed (14,000 MB/s) is identical across both capacities.

### How much DRAM does the BIWIN Black Opal X570 Pro 2TB have?

The 2TB model is equipped with 2GB of LPDDR4 DRAM. BIWIN scales DRAM with capacity across the X570 Pro lineup: 1GB on the 1TB, 2GB on the 2TB, 4GB on the 4TB, and 8GB on the 8TB model. The DRAM stores the logical-to-physical address mapping table on-chip, which delivers more consistent random read and write latency compared to DRAMless drives that rely on the system RAM via Host Memory Buffer. The 2GB allocation is appropriate for the 2TB NAND capacity.

### Is the BIWIN Black Opal X570 Pro 2TB compatible with the PS5?

Yes. The 2TB X570 Pro ships in M.2 2280 single-sided form at 2.50 mm height, which fits within the PS5's M.2 expansion bay (22 x 80 mm, 11.25 mm height maximum). Sony's minimum sequential read requirement for PS5 M.2 expansion is 5,500 MB/s; the X570 Pro's 14,000 MB/s read rating exceeds that threshold by a wide margin. The drive will operate at PCIe 4.0 speeds in the PS5's expansion bay rather than its full PCIe 5.0 rating, but still delivers substantially faster load times than any NVMe drive that only meets Sony's minimum spec.

### What is the TBW endurance of the BIWIN Black Opal X570 Pro 2TB?

The 2TB model is rated at 1,500 TBW (terabytes written) under the 5-year warranty. At 30 GB written per day — a realistic estimate for a desktop power user — 1,500 TBW represents over 130 years of rated endurance. At 100 GB per day, the budget stretches past 40 years. Content creators writing 300 GB daily have a 13-year horizon. For perspective, the 4TB model is rated at 3,000 TBW and the 1TB at 750 TBW. The 5-year warranty period will expire before TBW becomes a practical concern for most buyers.

### How does the BIWIN Black Opal X570 Pro 2TB compare to the Crucial T705 2TB?

Both are PCIe 5.0 NVMe drives with DRAM caches and Micron 232-layer TLC NAND. The Crucial T705 2TB uses the Phison E26 controller (12nm) while the BIWIN X570 Pro uses the Silicon Motion SM2508 (6nm). The SM2508's newer process gives it a thermal advantage — it runs cooler under sustained load without an external heatsink. On rated sequential performance the two are close: the T705 2TB is specified at 14,500 MB/s read and 14,000 MB/s write, edging the X570 Pro's 14,000/13,000 MB/s. The Crucial T705 has a substantially larger independent review and benchmark library and more established Western retail and RMA support. The X570 Pro's single-sided construction and SM2508 thermal efficiency are its distinguishing advantages.

### Does the BIWIN Black Opal X570 Pro 2TB need a heatsink?

Not for most use cases. The drive ships without a traditional aluminium heatsink, instead using a graphene thermal film bonded to the NAND for passive heat spreading. The SM2508's 6nm process generates less heat than the Phison E26 at equivalent workloads. KitGuru's testing recorded peak temperatures in the low-60°C range under sustained stress without an external heatsink — acceptable for a Gen5 drive. Modern Z790, X670E, and Z890 motherboards typically include built-in M.2 thermal pads that provide additional contact cooling. For compact ITX builds without M.2 thermal contact, a low-profile third-party M.2 heatsink is a sensible precaution for sustained-write workloads.

### Is the BIWIN Black Opal X570 Pro different from the standard X570?

Yes, they are distinct products and should not be confused. The X570 Pro uses the Silicon Motion SM2508 controller with dedicated DRAM (2GB LPDDR4 on the 2TB model), full PCIe 5.0 bandwidth, and Micron 232-layer TLC NAND. The standard X570 uses a DRAMless Maxiotek MAP1806a controller that relies on Host Memory Buffer instead of on-board DRAM. The Pro model commands a higher price for better sustained random I/O consistency and higher sequential write speeds. When comparing prices across sellers, confirm the full model name includes 'Pro' and verify the controller listed in the spec sheet.
