# Orico IG740 Pro 4TB Review — Bulk Budget Storage With a Warranty (2026)

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.

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. 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.

## Performance

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.

## Pros and Cons

**Pros:**

- 7,400 MB/s reads and 6,500 MB/s writes
- 2,400 TBW endurance with 5-year warranty
- Brass heatsink included in the box
- 4 TB at a budget-tier price point
- Scales the proven NM790-family platform
**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 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.

## Frequently Asked Questions

### Is the Orico IG740 Pro 4TB compatible with the PS5?

The specifications fit: 7,400 MB/s reads clear Sony's 5,500 MB/s recommendation, 4 TB is a comfortable console library size, and the required heatsink comes bundled — just confirm the assembled height with the brass cooler stays within Sony's 11.25 mm limit. Two practical caveats apply: the documented NAND batch variation makes early testing important, and Orico's support network is newer than the incumbents', which matters for a drive embedded in a console. A retail gaming drive with a consumer warranty remains the lower-risk console choice.

### Is the Orico IG740 Pro 4TB good for gaming?

As a pure game library, it is arguably the line's best fit: 4 TB holds dozens of 100 GB-plus installs without pruning, the 7,400 MB/s read rating loads everything at the practical ceiling of PCIe 4.0, and the 6,500 MB/s write rating makes re-downloading large titles painless. The DRAM-less design has no measurable effect on game loading. The sourcing caveat applies — reported QLC-swap units fill much more slowly — so test a large install shortly after purchase and keep the return window open.

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

No — the IG740 Pro is DRAM-less across the range, including the 4 TB. The Maxio MAP1602 controller uses Host Memory Buffer to store mapping tables in system RAM, and a pseudo-SLC cache carved from the NAND absorbs burst writes; at 4 TB that cache is the largest in the line, which softens the sustained-write drop-off on big transfers. Responsiveness in gaming and desktop use is nearly indistinguishable from DRAM-equipped drives. Constant professional-grade writing remains the workload where a DRAM-equipped design is worth the premium.

### What is the TBW endurance of the Orico IG740 Pro 4TB?

The 4 TB model is rated at 2,400 TBW under a 5-year limited warranty, whichever arrives first — the line's maximum, continuing its 600 TBW-per-terabyte scaling from 600 TBW at 1 TB and 1,200 TBW at 2 TB. At a heavy 40 GB of writes per day, exhaustion would take more than sixteen decades, so the rating is effectively unreachable within the warranty term. For an archive drive, that endurance headroom is exactly what makes a budget 4 TB purchase defensible — provided the unit carries the advertised TLC NAND.

### Does the Orico IG740 Pro 4TB need a heatsink?

It should have one, and it does — the bundled brass-and-aluminum cooler ships in the box. Denser NAND at 4 TB concentrates more heat in the same 2280 footprint, and Igor's Lab's testing of the platform found it running hot under sustained load even at 2 TB, concluding the bundled cooler should stay attached. A motherboard heatsink is an equally good substitute. For PS5 use, Sony requires a heatsink regardless, so the inclusion covers that base — subject to checking the assembled thickness against the 11.25 mm height limit.

### Orico IG740 Pro 4TB or Lexar NM790 4TB — which is better?

Same platform, different terms. The NM790 4TB carries 3,000 TBW of endurance to the Orico's 2,400 TBW, rides Lexar's longer-established brand and support network, and holds the identical 7,400/6,500 MB/s ratings — both are DRAM-less MAP1602 designs with YMTC NAND. The IG740 Pro 4TB typically undercuts it on price and includes the heatsink the base NM790 lacks. The decision rests on price gap versus brand assurance, sharpened by the Orico's batch-variation reports: pay for the Lexar's certainty, or save with the Orico and test on arrival.
