AIGO SM170 2 TB: The Reviewed Capacity of AIGO's SM2268XT Drive (2026)
The AIGO SM170 2 TB is the capacity TweakTown called the second-fastest 2 TB DRAM-less SSD it tested, with 7,400 MB/s reads, 1,000,000 IOPS, and 3,600 TBW.
Controller & Memory
The AIGO SM170 2 TB runs the Silicon Motion SM2268XT four-channel DRAM-less controller in front of a YMTC 232-layer TLC flash array at 2,400 MT/s, borrowing system memory through Host Memory Buffer for the flash translation layer instead of carrying a discrete DRAM chip. It is rated at 7,400 MB/s sequential reads and 6,400 MB/s sequential writes over PCIe 4.0 x4, with up to 1,000,000 random read and write IOPS, and it carries a five-year warranty backed by a 3,600 TBW endurance rating on the 2 TB capacity. The SM2268XT is the same class of fast DRAM-less PCIe 4.0 controller as Maxio's MAP1602, and the SM170 was among the first drives to pair it with YMTC's 232-layer NAND, a combination no major outlet had tested before TweakTown's review.
The SM170 line spans 1 TB, 2 TB, and 4 TB, all on the same controller, NAND, and HMB architecture. Sequential throughput holds at 7,400 MB/s reads across the family, and endurance scales at a notably high 1,800 TBW per terabyte, 1,800 TBW on the 1 TB, 3,600 TBW on the 2 TB reviewed here, and 7,200 TBW on the 4 TB, well above the 600 TBW-per-terabyte norm of older TLC drives. The 2 TB is the sweet spot of the line: it reaches the full 7,400 MB/s read speed and the full 1,000,000 IOPS, doubles the 1 TB's write budget, and carries a larger SLC cache for longer sustained-write headroom, without paying the 4 TB's capacity premium.
The defining caveat is availability. The SM170 has been distributed mainly through the Asian market, and TweakTown's review listed availability as a con alongside its strong performance numbers, which is why the product is flagged in some databases as temporarily only available in Asia. For buyers who can source it, the 2 TB competes directly with Maxio MAP1602 designs such as the Addlink S93, the WD Black SN770, and the Team Group MP44, all DRAM-less HMB drives in the same performance envelope. The SM170's edge over that group is endurance: the YMTC 232-layer TLC's 1,800 TBW-per-terabyte rating comfortably beats the 600 to 1,300 TBW those rivals carry at 2 TB. The trade-off is buying convenience and warranty accessibility, since AIGO does not run a global RMA portal comparable to Samsung's or WD's.

SM170 Temporarily Only Available in Asia Performance & Benchmarks
AIGO rates the SM170 2 TB at 7,400 MB/s sequential reads and 6,400 MB/s sequential writes over PCIe 4.0 x4, with up to 1,000,000 random read and write IOPS. The SM2268XT is a four-channel DRAM-less controller that extracts flagship PCIe 4.0 throughput from high-speed YMTC 232-layer TLC at 2,400 MT/s without discrete DRAM.

This 2 TB capacity is the one TweakTown reviewed directly, so its performance characterisation is first-hand. The review measured 953,000 random read IOPS on an AMD test bench, the second-highest result the lab had ever recorded for a flash-based DRAM-less SSD, and it recorded 4,294 MB/s in a heavy mixed-transfer workload that set a new lab record for a DRAM-less drive. TweakTown also measured 4K QD1 random read at roughly 102 MB/s, a strong real-world signal for boot and application responsiveness, and a 3DMark Storage Gaming score around 4,200, respectable but the lowest of the top three DRAM-less controller platforms the lab tracks. Those results are the headline reason the SM170 ranks among the best-performing DRAM-less SSDs tested, and they apply directly to this 2 TB model. As with every DRAM-less HMB design, sustained random write latency runs higher than on drives with discrete DRAM such as the Samsung 990 Pro or a Phison E18 drive, but those occupy a higher price tier. For boot, gaming, and everyday productivity, the SM2268XT's measured performance places the SM170 2 TB at the front of the DRAM-less field.

Endurance, TBW & Warranty
AIGO covers the SM170 2 TB with a five-year limited warranty, terminated by whichever arrives first between the term and the 3,600 TBW endurance rating. That 3,600 TBW figure, verified for this capacity by TechPowerUp, is unusually high for the budget PCIe 4.0 segment and sits well above the 1,200 TBW the WD Black SN770 and Addlink S93 carry at 2 TB or the 1,300 TBW of the Team Group MP44. It scales at 1,800 TBW per terabyte across the line, reflecting the write-cycle headroom of the YMTC 232-layer TLC. At a typical consumer write load of 20 GB per day, the 2 TB's 3,600 TBW rating translates to roughly 493 years before the write budget is exhausted, so the five-year term expires long before the NAND approaches its limit. The endurance advantage is most relevant for buyers who run sustained writes, such as game capture, video scratch work, or large backup rotations, where the doubled headroom over a 600 TBW-per-terabyte drive is a real benefit. The practical caveat is warranty accessibility: because the SM170 has been distributed primarily in Asia, buyers elsewhere should confirm retailer or distributor RMA support before purchase, as AIGO does not operate a global end-user RMA portal. Within its home market, the five-year term and the high TBW rating make a credible reliability story.

Verdict: Is the SM170 Temporarily Only Available in Asia Worth It in 2026?
The AIGO SM170 2 TB is the capacity to buy from this line if the budget allows, because it is the model TweakTown reviewed directly and called the second-highest-performing 2 TB DRAM-less SSD it had tested. It reaches the full 7,400 MB/s read ceiling of the SM2268XT platform, delivers a verified 1,000,000 IOPS, and pairs those numbers with a 3,600 TBW endurance rating that comfortably beats Maxio MAP1602 rivals like the Addlink S93, WD Black SN770, and Team Group MP44 at the same capacity. The 2 TB is the sweet spot: full peak performance, double the 1 TB's write budget, a larger SLC cache for sustained writes, and none of the 4 TB's capacity premium. The binding constraint remains availability, since the SM170 has been largely confined to the Asian market and AIGO lacks a global RMA portal, so buyers elsewhere should source it only through a retailer that handles warranty returns. Where the SM170 2 TB is obtainable, it is one of the strongest DRAM-less PCIe 4.0 values available; where it is not, the Addlink S93 or Team Group MP44 cover the same role on a more widely distributed platform, at the cost of lower endurance.
