Crucial E100 480GB VS Orico IG740 Pro 4TB

Sequential read speed determines how fast a drive can pull large, contiguous blocks of data — the metric most relevant for loading large files, booting applications, or transferring media. The Crucial E100 delivers 4700 MB/s, which is a competitive PCIe Gen 4 figure and comfortably fast for most everyday workloads. The Orico IG740 Pro, however, reaches 7400 MB/s, a figure characteristic of high-end PCIe Gen 5 drives — nearly 57% faster in this category.

In practice, that gap matters most in throughput-intensive scenarios: transferring multi-gigabyte video files, loading large game worlds, or working with dense datasets. For standard desktop use — web browsing, office apps, or even most gaming — the E100's speed is already beyond what bottlenecks the experience. The IG740 Pro's advantage becomes tangible primarily for content creators, data engineers, or professionals regularly moving large volumes of data.

On sequential read speed, the Orico IG740 Pro holds a clear and significant edge. Unless the use case specifically demands that ceiling, though, the E100 remains fast enough that most users would not feel the difference in day-to-day tasks.

Write speed is often the more telling half of a drive's performance story — it governs how quickly data is committed to storage, directly affecting save times, file ingestion, video capture, and backup throughput. Here the gap between these two drives is even more pronounced than on reads: the Crucial E100 posts 2500 MB/s, while the Orico IG740 Pro reaches 6500 MB/s — a difference of 160%.

For the E100, 2500 MB/s is a respectable figure for a mid-range drive and will handle most consumer workloads without friction — saving large documents, installing games, or backing up a phone. Where it starts to show its limits is under sustained heavy writes: think recording uncompressed 4K footage directly to the drive, ingesting large RAW photo libraries, or running virtual machines with frequent disk commits. The IG740 Pro's write ceiling absorbs those workloads with headroom to spare, making it a fundamentally different class of drive for write-intensive tasks.

The Orico IG740 Pro wins this category decisively. The margin is wide enough that it is not merely a benchmark curiosity — it translates into measurably faster real-world workflows for anyone pushing large amounts of data through their storage regularly.

At their foundation, both drives share the same form factor, interface generation (PCIe 4.0), NAND type (TLC), and cache architecture (HMB), making them structurally similar products on paper. The meaningful divergences emerge in the details. The Orico IG740 Pro runs NVMe 2.0 versus the E100's NVMe 1.4 — a newer protocol that enables more efficient queue management and better handling of mixed workloads, which partly explains the IG740 Pro's substantially higher real-world throughput figures seen in other categories.

Capacity is an obvious but important differentiator: 480GB versus 4TB places these drives in entirely different use-case tiers. More telling, however, is the endurance gap. The E100 carries a 60 TBW rating — typical for a low-capacity consumer drive — while the IG740 Pro is rated at 2400 TBW, a figure that reflects both its larger NAND pool and its positioning as a higher-endurance product. The warranty period reinforces this: 3 years on the E100 versus 5 years on the IG740 Pro, signaling a meaningful difference in the manufacturer's confidence in long-term reliability.

Across general specifications, the Orico IG740 Pro holds a clear structural advantage — newer NVMe protocol, vastly superior endurance, and a longer warranty. The E100 is a capable entry-level drive, but the IG740 Pro is built to a higher specification tier in nearly every foundational dimension.
