48TB Thunderbolt 5 NVMe RAID enclosure

The OWC ThunderBlade X12 delivers 48TB of NVMe SSD storage in a 12-bay RAID enclosure connected by Thunderbolt 5 at 80Gb/s. It supports RAID 0, 1, 4, 5, 10 and JBOD configurations managed by SoftRAID. Creative professionals handling multi-stream 8K or large dataset workloads gain a single high-capacity volume with hardware-accelerated redundancy options.

Sustained transfer up to 6600MB/s

Under continuous load the array maintains up to 6600MB/s throughput across the Thunderbolt 5 link, avoiding the thermal throttling typical of smaller portable SSDs. The 12-drive architecture distributes write cycles evenly, preserving consistent performance during long renders or backups. Buyers needing more than 48TB raw capacity or a second simultaneous Thunderbolt 5 host connection will need a different solution.

Questions about this item

How loud does the 12-drive ThunderBlade X12 get during sustained 6600MB/s workloads?

The enclosure uses an internal cooling system designed for continuous NVMe operation, but OWC does not publish a decibel rating for the ThunderBlade X12.

Which host port must my workstation provide to reach the advertised 80Gb/s bandwidth?

A Thunderbolt 5 port is required; the included cable connects the ThunderBlade X12 to that port for full 80Gb/s throughput.
