MPG previously discussed the OWC Envoy Pro SX features in OWC Introduces Envoy Pro SX Thunderbolt Bus-Powered Portable SSD.
Solidly built undersells just how well-built the OWC Envoy Pro SX is: it’s substantial as a solid chunk of metal and it feels like it. Connect it with the supplied Thunderbolt 3 cable.
The unit gets only slightly warm under full unrelenting use, but the solid metal build and the heat fins apparently make short work of heat.
Superb build aside, performance is top-tier, crazy fast for a single-blade external SSD.
Speed for even small trasnfer sizes ranks up there with the very best SSDs, starting out at 806 MB/sec for 32K reads, a feat that very few SSDs can manage. Small transfer size speed is important for responsiveness for all sorts of everyday tasks.
WOW! Bought too-small an SSD in your Mac or PC? Just plug one of these in and you’re 'good'.
*Mac users should reformat to APFS prior to usage, using the supplied utility on the drive, or Disk Utility.
