E901 1TB NVMe PCIe Gen3x4 M.2 SSD - High-Speed Internal Drive

In this review the E901 1TB NVMe PCIe Gen3x4 M.2 SSD is examined as a practical upgrade for users who need fast storage without fuss. The bottom line: it delivers consistently high sequential speeds and a modern feature set that make it a compelling choice for notebooks and desktops; the drive's use of 3D NAND and LDPC error correction are the single biggest reasons to consider it. Installation is straightforward thanks to the common 2280 M.2 form factor, and the manufacturer backs the product with a five-year warranty.

Key Features

• High sequential speed: Read speeds up to 3,400MB/s and write speeds up to 3,000MB/s provide noticeably faster file transfers and application load times compared with SATA SSDs.
• PCIe Gen3x4 interface: The NVMe PCIe Gen3x4 interface uses up to four lanes to deliver low latency and high throughput for everyday tasks and heavier workloads.
• 3D NAND flash: The use of 3D NAND increases endurance and storage efficiency over planar flash, which helps the drive maintain performance over time.
• LDPC error correction: Built-in LDPC ECC improves data integrity and extends the usable life of the SSD by correcting more complex bit errors.
• DRAM cache buffer supported: Onboard DRAM cache support helps maintain sustained performance under heavier read/write activity and multitasking.
• Wide OS compatibility: Works with Windows, Linux and Mac OS X systems that accept an M.2 NVMe module for broad device support.

Who It's For

The E901 is aimed at enthusiasts and mainstream users who want a clear upgrade over SATA SSDs or older NVMe drives without paying premium prices for the latest controllers. It fits well in ultrabooks, gaming laptops and desktop motherboards that accept a 2280 M.2 module and benefit from faster sequential throughput.

Users who require enterprise-grade features like power-loss protection or specialized firmware tuning should look elsewhere, as this model focuses on consumer performance and value rather than data-center features. Also, buyers with systems limited to SATA M.2 slots must confirm NVMe support before purchasing.

Pros & Cons

Pros

• Very fast sequential read and write performance suitable for large file transfers and game installs.
• Enhanced data integrity thanks to LDPC error correction and 3D NAND construction.
• DRAM cache buffer support helps with sustained workloads and multitasking.
• Five-year warranty provides added reassurance for long-term use.

Cons

• Does not advertise advanced enterprise protections like power-loss capacitors, so workloads requiring guaranteed write completion may need a different class of drive.
• Peak performance depends on the host platform; older motherboards may not reach the listed speeds.
