Product information

Description

The OWC Express 4M2 SSD enclosure White M.2 PCI Express 3.0 40 Gbit/s is a high-performance storage solution designed to house up to four NVMe M.2 drives, delivering a maximum capacity of 16 TB. Featuring a PCI Express 3.0 interface, a rapid 40 Gbit/s data transfer rate, and a versatile USB Type-C connector, this white enclosure brings desktop-class RAID capabilities to your workspace. It bridges the gap between massive storage capacity and incredible speed, allowing users to build a custom external drive using their preferred M.2 solid-state drives.

Advantages

This enclosure offers exceptional real-world performance reaching up to 3200MB/s, making data transfers and file access remarkably fast. It is engineered with broad compatibility, working seamlessly with USB4, Thunderbolt, and USB-C equipped Mac and PC computers. Constructed from aircraft-grade aluminum, the chassis provides rugged physical protection while functioning as an effective heat sink to dissipate warmth and maintain consistent speeds during intense workloads. Near-silent operation is achieved through smart, adaptive fans that activate only under heavy loads to keep internal components cool without creating distracting ambient noise.

Suitable for

  • Building high-performance NVMe SSD RAID setups with up to 16 TB of total capacity
  • Backing up large media cards from multiple cameras on set for DITs and filmmakers
  • Editing demanding 8K video, 4K RAW multi-cam sequences, and high-resolution photos
  • Handling fast data backups and intensive creative post-production workflows

When it may not be suitable

This enclosure may not be ideal for users seeking a pocket-sized portable drive, as it features a desktop form factor designed to accommodate four internal M.2 drives and an internal power supply. Additionally, it does not include extra auxiliary peripheral ports or daisy-chaining connectivity options found in some higher-end professional docking stations.

Key specifications

  • Product type: SSD enclosure
  • Number of storage drives supported: 4
  • Storage drive size: M.2 (2230, 2242, 2280)
  • Supported storage drive interfaces: PCI Express 3.0
  • Maximum storage capacity: 16 TB
  • Data transfer rate: 40 Gbit/s
  • Product colour: White
  • USB connector type: USB Type-C
  • Power source type: AC, DC

How to use

To assemble the unit, open the enclosure and insert your choice of compatible NVMe M.2 solid-state drives into the four available slots. Secure the drives according to the hardware instructions and close the casing securely. Connect the included 40 Gbit/s USB-C cable from the enclosure to a compatible USB4, Thunderbolt, or USB-C port on your computer, and connect the power supply to an electrical outlet. Once powered on, format the drives using your operating system disk utility or configure your preferred RAID array using compatible management software.

What to consider before purchase

  • Ensure your computer features a compatible USB4, Thunderbolt, or USB-C port to achieve optimal transfer speeds
  • Note that NVMe M.2 SSD drives are sold separately and must be acquired to use the enclosure
  • Review the physical dimensions if desk space is limited
  • Determine whether you need software-based RAID configuration for your workflow

Usage recommendations

For the best thermal performance and data integrity, place the enclosure on a flat, well-ventilated surface that allows unobstructed airflow around the aluminum chassis. Always use the included high-speed USB-C cable or certified 40 Gbit/s alternatives to ensure stable data transmission, and safely eject the storage volume from your operating system before disconnecting the power or cable.
