# Orico IG740 Pro 1TB Review — a Budget Sleeper With a Heatsink (2026)

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.

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. 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.

## Performance

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.

## Pros and Cons

**Pros:**

- 7,400 MB/s reads and 6,500 MB/s writes
- 600 TBW endurance with 5-year warranty
- Brass heatsink included in the box
- Same platform as pricier name-brand drives
- MTBF rated at 1.5 million hours
**Cons:**

- No DRAM cache on the PCB
- Reported NAND batch variation in some units
- Runs hot — the bundled cooler is a necessity
- Younger brand with a smaller support network


## Verdict

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.

## Frequently Asked Questions

### Is the Orico IG740 Pro 1TB compatible with the PS5?

The specs fit: 7,400 MB/s reads clear Sony's 5,500 MB/s recommendation with a wide margin, and the PCIe 4.0 NVMe interface is exactly what the PS5 expects. The heatsink Sony requires is actually included in the box — rare at this price — though buyers should confirm the assembled thickness with the brass cooler stays within Sony's 11.25 mm height limit before installation. The bigger consideration is warranty: Orico's support network is newer than the incumbents', which matters for a drive living inside a console.

### Is the Orico IG740 Pro 1TB good for gaming?

Yes — the rated 7,400 MB/s reads put it at the practical ceiling of PCIe 4.0, where game loading is as fast as the engine can stream, and the 6,500 MB/s write rating makes installing 100 GB-plus titles painless. DirectStorage titles get the full link speed. The DRAM-less design has no measurable effect on game loading. The one gaming-specific caveat is the reported batch variation: a QLC-swap unit would show much slower fills when reinstalling large libraries, so source the drive from a seller with easy returns.

### Does the Orico IG740 Pro have a DRAM cache?

No — the IG740 Pro is DRAM-less. The Maxio MAP1602 controller uses Host Memory Buffer to store the flash translation tables in system RAM, and a pseudo-SLC cache carved from the NAND absorbs write bursts. For boot duty, gaming, and everyday desktop work, responsiveness is nearly indistinguishable from DRAM-equipped drives. Sustained heavy writing is where the design shows: once the cache fills, throughput settles to native TLC rates — or lower, in the minority of units the community has flagged as QLC swaps.

### What is the TBW endurance of the Orico IG740 Pro 1TB?

The 1 TB model is rated at 600 TBW under a 5-year limited warranty, whichever arrives first. That maintains the line's 600 TBW-per-terabyte scaling — 1,200 TBW at 2 TB and 2,400 TBW at 4 TB — and matches what established brands offer in this class. Written out, 600 TBW is more than eight decades of use at a demanding 20 GB written per day, so within the warranty period the endurance ceiling is effectively unreachable for a typical gaming or boot workload.

### Does the Orico IG740 Pro need a heatsink?

No purchase necessary — one is in the box. The bundled brass-and-aluminum cooler is not decorative either: Igor's Lab's testing of the line found it running hot under sustained load, concluding the bundled cooler should stay attached. For PS5 buyers, Sony requires a heatsink anyway, so the inclusion solves that requirement too — just verify the assembled thickness stays within the 11.25 mm height limit. On a desktop, the motherboard's own heatsink remains a fine alternative if you prefer the cleaner look.

### Orico IG740 Pro 1TB or Lexar NM790 1TB — which is better?

They share the same platform — Maxio MAP1602 and YMTC TLC — and the same 7,400/6,500 MB/s ratings. The NM790 1TB holds the endurance edge at 1,000 TBW versus 600 TBW, and Lexar's brand has a longer support track record. The IG740 Pro counters with the bundled brass heatsink the base NM790 lacks and typically keener pricing. Choose the Lexar for maximum rated endurance and an established support network; choose the Orico when the price gap is wide enough and the included cooler suits the build.
