Orico IG740 Pro 4TB

Manufacturer: Orico

The Orico IG740 Pro 4TB is a high-capacity M.2 NVMe solid-state drive built around the MaxioTech MAP1602A Falcon Lite controller. It operates over a PCIe Gen 4 interface and conforms to the NVMe 2.0 specification, positioning it as a current-generation storage option for systems that support the standard. The drive ships without an integrated heatsink or RGB lighting, keeping its physical profile straightforward.

On the performance side, the IG740 Pro reaches sequential read and write speeds of 7400 MB/s and 6500 MB/s respectively, while random workloads are rated at 1,032,000 read IOPS and 861,000 write IOPS. The drive uses TLC NAND storage and relies on HMB (Host Memory Buffer) caching rather than dedicated DRAM. It ships with a rated endurance of 2400 TBW across its 4TB capacity and is backed by a five-year warranty. The controller operates across four channels.

Pros
  • Sequential read speed of 7400 MB/s and write speed of 6500 MB/s indicate strong throughput for data-intensive tasks
  • A 2400 TBW endurance rating on a 4TB drive suggests a reasonable lifespan for sustained workloads
  • NVMe 2.0 over PCIe Gen 4 ensures compatibility with current-generation motherboards and platforms
  • Five-year warranty provides long-term coverage relative to many storage devices
  • 4TB capacity offers substantial room for large libraries of files, games, or workloads
  • The absence of RGB lighting and a heatsink keeps the physical footprint minimal, which suits compact or space-constrained builds
Cons
  • Relies on HMB (Host Memory Buffer) instead of dedicated DRAM, which may result in reduced performance consistency under heavy sustained workloads
  • No integrated heatsink means thermal management depends entirely on the host system
  • Four controller channels is a relatively modest configuration for a 4TB drive, which can limit parallelism at the hardware level
  • TLC NAND, while common, generally offers lower endurance per cell compared to MLC-based alternatives
Who is this for?

This drive is well-suited to users who work with large sequential data transfers, such as those handling high-resolution video editing, large game libraries, or extensive data archiving, thanks to its 7400 MB/s read and 6500 MB/s write speeds alongside a 4TB capacity. The PCIe Gen 4 and NVMe 2.0 interface makes it a practical fit for modern desktop or laptop builds where a current-generation M.2 slot is available. Its 2400 TBW rating also makes it a reasonable choice for users who need a drive that can sustain frequent, high-volume write activity over an extended period without quickly exhausting its rated lifespan.

Who is this NOT for?

Users running sustained, cache-intensive workloads may find the HMB-based caching a limiting factor, as performance can degrade more noticeably during prolonged operations compared to drives with dedicated DRAM. The lack of an integrated heatsink makes this drive a poor match for high-throughput server environments or chassis configurations where active thermal management is not provided by the system itself. Additionally, users on older platforms that only support PCIe Gen 3 or earlier would not be able to fully utilize the drive's rated speeds, making it a less practical fit for legacy system upgrades.

Read speed:

sequential read speed 7400 MB/s
random read speed 1032000 IOPS

The Orico IG740 Pro 4TB delivers a sequential read speed of 7400 MB/s, making it capable of moving large files at a sustained pace. For workloads involving smaller, non-contiguous data, the drive is rated at 1,032,000 read IOPS, reflecting solid throughput under random access conditions.

Write speed:

sequential write speed 6500 MB/s
random write speed 861000 IOPS

The Orico IG740 Pro 4TB is rated for a sequential write speed of 6500 MB/s, allowing large volumes of data to be written at a consistent pace. Under random write conditions, the drive reaches 861,000 IOPS, indicating its ability to handle workloads that involve frequent, scattered write operations across the storage space.

The Orico IG740 Pro 4TB is an M.2 form factor NVMe SSD operating on the PCIe Gen 4 interface and conforming to NVMe version 2, with a total internal storage capacity of 4000GB. It is built around the MaxioTech MAP1602A Falcon Lite controller, which operates across four channels, and uses TLC NAND as its underlying storage type. Rather than dedicated DRAM, the drive relies on HMB (Host Memory Buffer) for caching purposes. Endurance is rated at 2400 TBW, and the drive is covered by a five-year warranty. It does not include an integrated heatsink or RGB lighting.

Final Verdict

The Orico IG740 Pro 4TB is a capable M.2 NVMe SSD that covers the essentials expected of a current-generation PCIe Gen 4 drive, combining a 4TB capacity with strong sequential throughput and a 2400 TBW endurance rating that gives it credibility for sustained workloads over its five-year warranty period. Its reliance on HMB caching rather than dedicated DRAM and the absence of an integrated heatsink mean it is best deployed in systems that can compensate for those trade-offs at the platform level. For users with a compatible modern system who need generous storage capacity and consistent large-file performance, the IG740 Pro represents a straightforward, no-frills option that delivers on its core specifications without unnecessary additions.
