The OWC Mercury Elite Pro Dual 32TB pairs two pre-installed 16TB 7200 RPM drives inside a single aluminum enclosure, configurable via a physical RAID switch. In RAID 0 mode, it delivers up to 407 MB/s sustained throughput — fast enough for 4K HD video editing directly from the external array. The enclosure supports USB 3.2 Gen 1 (5 Gb/s) and eSATA 6 Gb/s with port multiplier functionality for legacy workstation compatibility.

Hardware RAID management means the array is OS-independent, functioning identically on Windows, macOS, and Linux without RAID driver conflicts. The anodized aluminum body acts as a passive heatsink, and the replaceable internal fan keeps temperatures under control during long transfers. OWC provides a 1-year limited warranty with US-based support, and the drives are user-serviceable with standard 3.5-inch SATA units.

Customer feedback highlights easy RAID 1 setup for mirroring critical data, quiet operation in office environments, and successful integration with Raspberry Pi and ZFS-based NAS builds. A significant warning: some users experienced silent data corruption in RAID 1 across multiple enclosures, where both drives failed simultaneously. A backup strategy beyond the single RAID 1 array is strongly advised for irreplaceable data.
