Orico IG740 Pro 4TB Review — Bulk Budget Storage With a Warranty (2026)
Quick answer
Buy the Orico IG740 Pro 4TB when the project is bulk: a media archive, a home-server pool, or a game library that has already outgrown 2 TB, and the budget cannot stretch to name-brand 4 TB pricing.
Read: 7400 MB/s Write: 6500 MB/s Endurance: 2400 TBW Warranty: 5 years Interface: M.2 4.0 x 4
The Orico IG740 Pro 4TB scales the budget line to 2,400 TBW of endurance with the same 7,400 MB/s speeds, bundled cooler and 5-year warranty intact.
Controller & Memory
The Orico IG740 Pro 4TB is the range-topping capacity of Orico's value Gen4 line, and it exists to answer one question: how cheap can four terabytes of fast TLC storage get without giving up the essentials? The essentials are intact — Maxio's DRAM-less MAP1602 controller with Host Memory Buffer, YMTC TLC behind it, and the same 7,400 MB/s read and 6,500 MB/s write ratings every capacity in the line carries over PCIe 4.0 x4. The bundled brass heatsink comes along too, which at four terabytes is less a bonus than a requirement, since denser NAND packages concentrate more heat in the same 2280 footprint.
Endurance is where the capacity pays for itself: 2,400 TBW under a 5-year warranty, continuing the line's clean 600 TBW-per-terabyte scaling from 600 TBW at 1 TB and 1,200 TBW at 2 TB. That rating puts the 4 TB model in the same endurance class as far more expensive name-brand bulk drives, and the platform is the same one powering the Lexar NM790, whose 4 TB carries 3,000 TBW — the Orico trades 600 TBW and brand pedigree for price. The Silicon Power UD90 and Kingston NV3 bracket the same budget tier from either side.
The standing caveat deserves the loudest voice here: community testing has documented units shipping with QLC instead of the advertised TLC, with post-cache writes collapsing to a fraction of spec. At 4 TB — the capacity most likely to be bought as long-term archive — a bad batch matters most, so screening on arrival and buying from a return-friendly seller are part of the purchase, not paranoia. Land a TLC unit and the audience is obvious: archive builders, home-server operators, and gamers whose libraries have outgrown the 2 TB tier entirely.

IG740 Pro Performance & Benchmarks
The 4 TB IG740 Pro carries the line's full ratings unchanged: 7,400 MB/s sequential reads and 6,500 MB/s writes over PCIe 4.0 x4. Review consensus on the platform comes from the smaller capacities — Tom's Hardware's budget-sleeper verdict on the 1 TB, TweakTown's value endorsement and Igor's Lab's solid-midfield placement on the 2 TB — and nothing about the 4 TB layout suggests a different character, only denser NAND and the thermal load that comes with it.

Bulk capacity changes the sustained-write story in the buyer's favor. The pseudo-SLC cache scales with the NAND behind it, so the transfers that would exhaust a 1 TB drive's cache and expose native TLC rates are proportionally rarer here; archives, library migrations, and home-server writes mostly stay inside the fast zone. When the cache does fill, throughput settles to native TLC rates — or lower on the QLC-swap units the community has flagged, which is why arrival testing matters. Thermals need respect: the platform runs hot under sustained load even at 2 TB per Igor's Lab, so the bundled brass cooler should stay attached or a motherboard heatsink take its place. Within those boundaries, this is honest, fast bulk storage at a price that makes the bigger brands uncomfortable.

Endurance, TBW & Warranty
Orico rates the IG740 Pro 4TB at 2,400 TBW under a 5-year limited warranty, whichever arrives first — the largest endurance budget in the line, maintaining its clean 600 TBW-per-terabyte scaling. At a heavy 40 GB written per day, that budget stretches past sixteen decades, meaning even archive workloads will never approach the ceiling within the warranty term. The rated MTBF is 1.5 million hours, a fleet-level statistic rather than a promise about any individual drive. Orico's 5-year coverage matches the established brands on paper, but the practical safety net for a 4 TB bulk purchase is the seller's return window — community reports of NAND batch variation on this line make the first few weeks of ownership the real test period.

Verdict: Is the IG740 Pro Worth It in 2026?
Buy the Orico IG740 Pro 4TB when the project is bulk: a media archive, a home-server pool, or a game library that has already outgrown 2 TB, and the budget cannot stretch to name-brand 4 TB pricing. Its 7,400/6,500 MB/s ratings, 2,400 TBW endurance, and included cooler make a complete case — with one condition: verify the unit early, because the documented QLC-swap batches turn this from a bargain into a liability. Skip it if consistency guarantees matter more than price; the Lexar NM790 4TB offers the same platform with 3,000 TBW and a longer track record, while retail alternatives like the Crucial P3 4TB serve the same QLC-and-QLC-adjacent budget tier differently. For patient, testing buyers, this is the budget end of 4 TB Gen4.
