High-speed NVMe storage

The Orico e7400-4TB is a 4 TB M.2 2280 internal SSD that connects through a PCIe 4.0 x4 interface. It uses QLC flash memory and delivers sequential reads up to 7400 MB/s and writes up to 6600 MB/s. A graphene heat spreader helps manage temperatures during heavy workloads. The drive is aimed at gamers and creators who need large, fast storage.

Best for high-capacity speed needs

This drive suits users who want maximum capacity with PCIe 4.0 performance for large game libraries, video projects or heavy multitasking. It works in desktops, laptops and consoles that have an NVMe M.2 slot. Buyers who need the higher endurance of TLC flash or who have only PCIe 3.0 slots should consider other options.

PCIe 4.0 x4 interface

The single specification that decides compatibility is the PCIe 4.0 x4 NVMe interface. Your motherboard or device must provide an M.2 2280 key‑M slot wired for NVMe over PCIe 4.0 to achieve the quoted speeds. If the slot is limited to PCIe 3.0 the drive will still function but at reduced throughput.

Questions about this item

Which capacity should I choose for the Orico e7400 — 512GB, 1TB, 2TB or 4TB?

The 4TB model gives the most space for large game libraries and creative projects, while 1TB or 2TB suit everyday workloads and tighter budgets.

What do the 7400 MB/s read and 6600 MB/s write figures mean once the drive is installed?

They are peak sequential speeds over PCIe 4.0 x4; real-world loads such as game loading or file transfers will run lower but still benefit from the headroom.

How does the PCIe 4.0 x4 interface cap performance in practice?

The four-lane Gen 4 link limits sequential throughput to the quoted 7400 MB/s read and 6600 MB/s write ceilings.
