Four-Bay NVMe RAID Enclosure

The OWC Express 4M2 is a four-bay NVMe M.2 SSD enclosure with a USB 4.0 40Gbps external interface. It accepts 2230, 2242 and 2280 form factors and ships with SoftRAID Premium software. Aircraft-grade aluminum construction provides heat dissipation for sustained performance up to 3200MB/s real-world speed.

Creative Professionals and DIY Builders

This enclosure suits users building a high-performance desktop RAID array with their own choice of NVMe SSDs. Smart adaptive fans stay off until thermal load requires them, enabling near-silent operation for audio or video work. It is not suited for buyers needing 2.5-inch or 3.5-inch drive support, or those requiring more than four M.2 slots.

USB 4.0 40Gbps Host Connection

The single specification that determines compatibility is the USB 4.0 40Gbps (USB-C) host interface. Your computer must provide a USB4, Thunderbolt or USB-C port capable of this bandwidth to reach the advertised 3200MB/s throughput. Older USB 3.x ports will limit performance proportionally.

商品問答

What comes in the box and do I need to buy SSDs separately?

The enclosure ships with a USB4 cable and an AC adapter. You must supply up to four NVMe M.2 2230, 2242 or 2280 SSDs yourself.

Which M.2 lengths does the enclosure accept?

Each of the four bays supports NVMe M.2 2230, 2242 and 2280 drives, so you can mix capacities and form factors as you wish.

What does the 3200MB/s figure mean in daily use?

That is the real-world throughput ceiling over the USB4 40Gbps link when the installed SSDs are configured in a RAID set.
