MPG tested the about $950 8.0TB OWC Envoy Express under hot conditions of 85°F (no air conditioning in the office). That along with the demanding continuous writing is a pretty tough test of any SSD.
To its credit, the Envoy Express performed without a hitch under maximally demanding conditions that no normal usage would ever require. While its write speed (red line) did drop off just shy of the 3.2TB mark, it still sustained write speed for 8TB that exceeds the fastest USB-C SSDs. It’s unclear if this dropoff might have been due to environmental conditions (hot office), and with no relief in sight, I did not retest.
But what really counts for all but rare cases of real-world usage is read speed. Read speed (green line) pegs-out 1599 MiB/sec = 1677 MB/sec which exceeds the claimed rating of 1553 MB/sec by 8% faster. Moreover, the Envoy Express sustained that speed with nil variation for the full 8TB capacity.
Since the Aura Ultra IV SSD blade is stated to deliver around 7GB/sec, it appears that the Envoy Express enclosure limits the blade speed to about half of the Thunderbolt 3 bus speed. Why this is so is not clear.
Write, average = 1111 MiB/sec = 1165 MB/sec
Read average = 1599 MiB/sec = 1677 MB/sec
A clone backup was made, with excellent speed. Following that, IntegrityChecker Java verified that backup of 356689 files totaling 1132.1 GiB on the Envoy Express, with throughput very close to the read speed of 1566 MiB/sec = 1642MB/sec.
