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.
Controller & Memory
Inside the Black Opal X570 Pro sits Silicon Motion's SM2508 — an 8-channel, 6nm PCIe 5.0 controller that competes directly with the 12nm Phison E26 found in most rival Gen5 drives. The 2TB model pairs the SM2508 with 2GB of LPDDR4 DRAM for logical-to-physical address mapping and Micron 232-layer TLC NAND across a full complement of NAND die. That additional NAND die count relative to the 1TB model pushes the sequential write ceiling up from 10,500 MB/s to 13,000 MB/s and raises the random read IOPS rating from 1,600,000 to 2,000,000 — a meaningful gain for workloads that exercise write throughput and deep-queue random reads simultaneously. The drive ships in M.2 2280 single-sided form at just 2.50 mm tall, which keeps it within the height clearance needed for PS5 expansion slots and slim laptop M.2 bays.
BIWIN (BIWIN Storage Technology Co., Ltd.) is a Shenzhen-based manufacturer with a background in embedded NAND and OEM memory solutions. The consumer Black Opal line is a more recent move into branded retail storage, and the X570 Pro represents the company's performance flagship. KitGuru awarded the 2TB model an 8.5 score in their dedicated review, noting efficient thermal management and strong sustained throughput. A graphene thermal film bonded directly to the NAND provides passive heat spreading without requiring a traditional aluminium heatsink, and the SM2508's 6nm process generates less heat than the 12nm Phison E26 under equivalent loads.
The 2TB capacity sits at a useful crossroads in the X570 Pro lineup: it delivers the full 13,000 MB/s write speed shared with the 4TB model but at a lower price and in the same compact single-sided footprint. Buyers who found the 1TB's 10,500 MB/s write ceiling limiting for video production or large-file workflows get a genuine performance step up here, not just more storage space. The 2TB model is the natural choice for users building a primary NVMe drive for demanding content creation alongside a secondary storage drive. It competes in the same segment as the Crucial T705 2TB and Corsair MP700 Pro 2TB, both of which use the Phison E26 platform.

Black Opal X570 Pro Performance & Benchmarks
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.

- Corsair MP700 Pro XT 4 TB: 14,900 MB/s read, 14,400 MB/s write
- Crucial T710 1 TB: 14,900 MB/s read, 13,800 MB/s write
- PNY XLR8 CS3250 1 TB: 14,900 MB/s read, 13,500 MB/s write
- PNY XLR8 CS3250 2 TB: 14,900 MB/s read, 14,000 MB/s write
- BIWIN Black Opal X570 Pro 2 TB (this drive): 14,000 MB/s read, 13,000 MB/s write
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.

Verdict: Is the Black Opal X570 Pro Worth It in 2026?
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.
