# BIWIN Black Opal X570 Pro 1TB — PCIe 5.0 NVMe SSD Review (2026)

The BIWIN Black Opal X570 Pro 1TB is a PCIe 5.0 NVMe SSD built on Silicon Motion's SM2508 controller with Micron 232-layer TLC NAND, rated at 14,000 MB/s sequential reads and 10,500 MB/s writes in the compact single-sided M.2 2280 form factor.

Quick answer: The BIWIN Black Opal X570 Pro 1TB is a technically sound PCIe 5.0 NVMe drive that delivers what it promises: 14,000 MB/s sequential reads, 10,500 MB/s writes, and a 6nm SM2508 controller that runs cooler than the first-generation Phison E26 drives that dominate this segment. The 5-year warranty and 750 TBW endurance rating are competitive for the price. The single-sided M.2 2280 design is a practical advantage for PS5 installations and laptops with strict M.2 height clearances.

## Performance

The BIWIN Black Opal X570 Pro 1TB is rated at 14,000 MB/s sequential reads and 10,500 MB/s sequential writes on PCIe 5.0 x4 — figures that are in line with the first generation of Gen5 consumer SSDs. The 10,500 MB/s write rating is lower than the 2TB and 4TB variants (rated at 13,000 MB/s) because the 1TB model has fewer NAND die available for simultaneous operations and a smaller pSLC write cache. This is a normal capacity-scaling characteristic rather than a quality issue.

For random access, BIWIN rates the 1TB at 1,600,000 read IOPS and 1,600,000 write IOPS. In workloads that exercise sustained sequential throughput — video editing, large game asset transfers, bulk media ingestion — the 14,000 MB/s read figure represents roughly double the bandwidth available on the fastest PCIe 4.0 x4 drives. For DirectStorage-enabled titles that decompress game assets from the SSD to the GPU, the Gen5 bandwidth headroom is directly exploitable. For everyday OS and application use, the difference over a well-optimised PCIe 4.0 drive narrows substantially, as those workloads are gated by random 4K latency and OS overhead rather than sequential bandwidth.

The SM2508's 6nm process gives it a thermal advantage over the 12nm Phison E26. KitGuru's 4TB X570 Pro thermal testing recorded a peak of 60°C under stress without an external heatsink, which is notably cooler than equivalent E26 testing. The graphene thermal film on the NAND contributes to this. That said, the drive is not recommended for installations without any airflow or thermal contact, and motherboards with built-in M.2 thermal pads are the preferred environment for sustained-write workloads. The 1GB LPDDR4 DRAM cache is sized for the 1TB capacity and ensures the SLC buffer is backed by real on-board address-translation memory rather than the Host Memory Buffer workaround used by DRAMless designs.

## Endurance, TBW & Warranty

BIWIN backs the Black Opal X570 Pro with a 5-year limited warranty across all capacity variants. The 1TB model carries a TBW (terabytes written) endurance rating of 750 TBW — the total write volume covered before the endurance warranty clause applies. At a typical desktop write workload of 30 GB per day, 750 TBW represents approximately 68 years of use before the endurance budget is exhausted. Even at a heavier 100 GB per day write rate — common in content creation workflows — the drive would take over 20 years to reach its rated limit. The 5-year clock will expire long before TBW becomes relevant for the vast majority of buyers. Video editors and data engineers writing 300 GB or more per day will see a shorter effective horizon, but that use case is better served by the 2TB or 4TB models with their 1,500 TBW and 3,000 TBW ratings respectively. Warranty service is handled through BIWIN's support process; as a brand with limited retail presence in Western markets, buyers should confirm regional warranty availability before purchasing from grey-market or import channels.

## Pros and Cons

**Pros:**

- 14,000 MB/s sequential reads on PCIe 5.0 x4
- Silicon Motion SM2508 controller on 6nm — runs cooler than Phison E26
- Micron 232-layer TLC NAND with 1GB LPDDR4 DRAM cache
- Single-sided M.2 2280 — compatible with PS5 and slim laptops
- 5-year warranty with 750 TBW endurance
- Graphene thermal film for passive heat spreading without a bulky heatsink
- NVMe 2.0 with PCIe 4.0 and 3.0 backward compatibility
**Cons:**

- Sequential write speed (10,500 MB/s) is notably lower than the 2TB/4TB models (13,000 MB/s)
- Limited brand recognition and retail presence in Western markets
- No bundled heatsink — relies on graphene film alone for thermal management
- Regional warranty support may be limited outside Asia for grey-market imports
- Smaller independent benchmark library than established brands like Samsung or WD


## Verdict

The BIWIN Black Opal X570 Pro 1TB is a technically sound PCIe 5.0 NVMe drive that delivers what it promises: 14,000 MB/s sequential reads, 10,500 MB/s writes, and a 6nm SM2508 controller that runs cooler than the first-generation Phison E26 drives that dominate this segment. The 5-year warranty and 750 TBW endurance rating are competitive for the price. The single-sided M.2 2280 design is a practical advantage for PS5 installations and laptops with strict M.2 height clearances.

The honest caveats are brand recognition and retail availability. BIWIN does not yet have the review depth, tooling ecosystem, or established return/RMA network in Western markets that Samsung, WD, or Crucial offer. Buyers comfortable purchasing from a Shenzhen-based manufacturer with growing but limited Western retail presence will find the X570 Pro 1TB a competitive choice at its price point. Buyers who prioritise established brand support and the broadest compatibility software ecosystem should look at the Crucial T705 1TB or Corsair MP700 Pro 1TB first. The 1TB write speed of 10,500 MB/s is also noticeably lower than the 2TB model's 13,000 MB/s; users who anticipate sustained-write workloads should budget for the 2TB.

## Frequently Asked Questions

### What controller does the BIWIN Black Opal X570 Pro 1TB use?

The Black Opal X570 Pro uses Silicon Motion's SM2508 controller — an 8-channel, PCIe 5.0 part built on a 6nm TSMC process. The SM2508 is a direct competitor to the Phison E26 that powers most other Gen5 consumer SSDs (Crucial T705, Corsair MP700 Pro, Seagate FireCuda 540). The 6nm process gives the SM2508 a thermal advantage over the 12nm E26: under sustained load the X570 Pro runs noticeably cooler. The 1TB model pairs the SM2508 with 1GB of LPDDR4 DRAM for the logical-to-physical address mapping table.

### Is the BIWIN Black Opal X570 Pro 1TB different from the X570 (non-Pro)?

Yes, they are distinct products. The X570 Pro uses the Silicon Motion SM2508 controller with DRAM (1GB LPDDR4 on the 1TB model). The standard X570 uses a DRAMless Maxiotek MAP1806a controller, which is a lower-cost 6nm part with no dedicated DRAM cache — it relies instead on the system RAM via Host Memory Buffer (HMB). The Pro model's DRAM cache delivers more consistent performance under heavy random workloads and sustained sequential writes. If you are comparing the two, verify the controller listed in the spec sheet; the product names are similar enough to cause confusion.

### Does the BIWIN Black Opal X570 Pro 1TB need a heatsink?

Not for most consumer workloads, but it benefits from some thermal contact. The drive ships without a traditional aluminium heatsink, instead relying on a graphene thermal film bonded directly to the NAND package for passive heat spreading. KitGuru's thermal testing on the 4TB model (the higher-heat variant) reached only 60°C under sustained stress without an external heatsink, which is a good result for a PCIe 5.0 drive. The 1TB model generates less heat than the 4TB due to fewer active NAND dies. Most modern Z790, X670E, and Z890 motherboards include built-in M.2 thermal padding, which provides sufficient supplemental cooling. For compact ITX builds without M.2 thermal contact, an inexpensive third-party M.2 heatsink is worth adding.

### What is the TBW endurance of the BIWIN Black Opal X570 Pro 1TB?

The 1TB model is rated at 750 TBW (terabytes written) — this is the endurance budget covered by the 5-year warranty. At a typical desktop write rate of 30 GB per day, 750 TBW translates to roughly 68 years of use before the endurance threshold is reached. Even at 100 GB per day, it would take over 20 years. For the vast majority of desktop and gaming users, TBW will never be the limiting factor before the 5-year warranty expires. If you regularly write 300 GB or more per day, the 2TB model (1,500 TBW) or 4TB model (3,000 TBW) would be more appropriate for your workload.

### How does the BIWIN Black Opal X570 Pro 1TB compare to the Crucial T705 1TB?

Both are PCIe 5.0 NVMe drives with DRAM caches and Micron 232-layer TLC NAND, but they use different controllers. The Crucial T705 uses the Phison E26 (12nm), while the BIWIN X570 Pro uses the Silicon Motion SM2508 (6nm). The SM2508's newer process gives it a thermal advantage — the X570 Pro tends to run cooler under load. On rated speeds, the T705 1TB is specified at 14,500 MB/s read and 11,700 MB/s write, edging the X570 Pro's 14,000/10,500 MB/s, particularly on sequential writes. The Crucial T705 has a larger independent review and benchmark library. The X570 Pro's single-sided construction is an advantage for PS5 and slim laptop compatibility. Price and availability at time of purchase will often be the deciding factor.

### Does the BIWIN Black Opal X570 Pro 1TB work in a PS5?

Yes. The X570 Pro 1TB uses the M.2 2280 form factor in a single-sided design, which fits within the PS5's M.2 expansion bay dimensions (22 x 80 mm, 11.25 mm height maximum). Sony requires a minimum sequential read speed of 5,500 MB/s for PS5 M.2 expansion, and the X570 Pro's 14,000 MB/s read rating exceeds that by a wide margin. The drive operates at PCIe 5.0 speeds when installed in a Gen5 M.2 slot, and falls back to PCIe 4.0 in the PS5's expansion bay — still delivering full performance well above Sony's minimum threshold. No heatsink is required from Sony, and the X570 Pro's graphene thermal film helps manage heat in the PS5's relatively confined storage bay.

### Why is the write speed on the 1TB model lower than the 2TB and 4TB?

The 1TB Black Opal X570 Pro is rated at 10,500 MB/s sequential writes, compared to 13,000 MB/s for the 2TB and 4TB models. This is standard NAND parallelism scaling: the 1TB model has fewer NAND die available for simultaneous write operations, which reduces the maximum sustained write bandwidth and limits the pSLC (pseudo-SLC) write cache size. Once the SLC cache is saturated on a 1TB drive, the controller must write to TLC mode at a lower rate than a 2TB drive with twice as many die. For gaming, OS use, and general productivity this difference is not perceptible. For sustained large-file writes — video capture, backup jobs, disk imaging — the 2TB model's higher write ceiling is meaningfully faster.

### Is BIWIN a reliable brand for SSDs?

BIWIN (BIWIN Storage Technology Co., Ltd.) is a Shenzhen-based manufacturer with a background in OEM NAND and embedded storage solutions. The consumer Black Opal SSD line is a newer venture, and the brand is less established in Western retail than Samsung, WD, Crucial, or Corsair. Independent reviews from KitGuru and igorslab have rated the X570 Pro positively for performance and build quality. The primary concerns for buyers in Western markets are the more limited retail presence, narrower independent review history, and uncertainty about regional RMA/warranty support for units purchased through import or grey-market channels. For buyers purchasing through established local retailers with a clear warranty process, the X570 Pro's hardware quality has been well-received by reviewers who have tested it.
