Orico IG740 Pro 1TB Review — a Budget Sleeper With a Heatsink (2026)
Quick answer
Buy the Orico IG740 Pro 1TB when the budget is fixed and the spec sheet refuses to compromise: rated 7,400/6,500 MB/s, 600 TBW, a 5-year warranty, and a heatsink actually included — the complete budget-Gen4 bundle.
Read: 7400 MB/s Write: 6500 MB/s Endurance: 600 TBW Warranty: 5 years Interface: M.2 4.0 x 4
The Orico IG740 Pro 1TB runs the familiar MAP1602-and-YMTC recipe at 7,400 MB/s, throws a brass heatsink in the box, and keeps the name-brand spec sheet.
Controller & Memory
The Orico IG740 Pro 1TB is built on the platform that quietly became the value-Gen4 standard: Maxio's DRAM-less MAP1602 controller with Host Memory Buffer, YMTC TLC behind it, and rated speeds of 7,400 MB/s reads and 6,500 MB/s writes over PCIe 4.0 x4. Those are the same fundamentals powering several bigger-name drives, and Orico leans into it, marketing the line as genuinely Chinese-designed storage — domestic controller, domestic NAND. What separates this drive from most budget sticks is what is in the box: a brass-and-aluminum heatsink comes bundled, a rarity at this tier, and Tom's Hardware's 1 TB review concluded the package is a competent, no-frills small sleeper.
The 1 TB model is the entry point of a range that scales to 4 TB, and its endurance rating of 600 TBW under a 5-year warranty matches what the established brands offer per terabyte. Line-mates double the budget at each step — 1,200 TBW at 2 TB, 2,400 TBW at 4 TB — while keeping the same speed ratings. Against the platform-twin Lexar NM790 1TB, Orico's drive gives up 400 TBW of rated endurance and the bigger brand's support network, but counters with the bundled cooler the NM790 base model lacks; the Kingston NV3 and Silicon Power UD90 fight the same price bracket with fewer cards in hand.
One honest caveat belongs in every conversation about this drive: community testing has flagged batch variation, with some units reportedly carrying QLC instead of the advertised TLC and posting much slower post-cache writes. The locked-down controller makes verification awkward, so buying from a seller with easy returns is the sensible hedge. Within that caveat, the audience is plain — budget Gen4 builders who want rated performance, a real warranty, and a heatsink without paying name-brand prices.

IG740 Pro Performance & Benchmarks
The 1 TB IG740 Pro is rated at 7,400 MB/s sequential reads and 6,500 MB/s writes over PCIe 4.0 x4 — peak-tier Gen4 figures shared across the whole range. Tom's Hardware's review of this capacity found it hitting the right performance points for the money, matching drives well above its price in several benchmarks, if with some variance across suites. In day-to-day terms the ratings translate to what they always do at this tier: instant boots, level loads indistinguishable from flagship drives, and DirectStorage titles with the full PCIe 4.0 link available.

The DRAM-less design shapes the edges. Writes ride a pseudo-SLC cache, and once a very large transfer exhausts it, throughput settles to native TLC rates — or dramatically lower, in the batch-variation cases the community has flagged, which is why the QLC caveat matters and a return-friendly seller is part of the performance story. Thermals are the other headline: Igor's Lab found the platform running hot under sustained load on the 2 TB model, so the bundled brass heatsink is not a gimmick but a functional necessity — keep it attached. With the cooler fitted and a TLC unit in hand, reviewers describe exactly the drive the price suggests it should not be: a genuine 7,400 MB/s Gen4 experience at budget money.

Endurance, TBW & Warranty
Orico backs the IG740 Pro 1TB with a 5-year limited warranty rated to 600 TBW, whichever arrives first — matching the per-terabyte endurance and warranty terms of the established brands at typically lower prices. Six hundred terabytes of writes works out to more than eight decades at a demanding 20 GB per day, so the warranty clock, not the endurance ceiling, is the practical limit. The rated MTBF is 1.5 million hours, a fleet-level statistic rather than a promise about any individual stick. Orico's support network is younger than the incumbents', so the retailer's return window carries extra weight — particularly given the community reports of NAND batch variation on this line.

Verdict: Is the IG740 Pro Worth It in 2026?
Buy the Orico IG740 Pro 1TB when the budget is fixed and the spec sheet refuses to compromise: rated 7,400/6,500 MB/s, 600 TBW, a 5-year warranty, and a heatsink actually included — the complete budget-Gen4 bundle. Skip it if brand support and verified consistency matter more than price; the Lexar NM790 1TB offers the same platform with higher rated endurance and a longer track record, and the Kingston NV3 carries a household name into the same bracket. The batch-variation reports are the real risk factor, so buy from a seller that takes returns. If the unit you receive is one of the good ones — and most are — this is one of the sharpest value plays in PCIe 4.0.
