At a glance
Expert’s Rating
Pros

- Sturdy design
Cons
- Thunderbolt only
Our Verdict
The Envoy Pro SX is Thunderbolt storage for your Mac that performs very well. However, it’s Thunderbolt only, and its USB-equipped sibling, the Envoy Pro FX, is only $20 more than the SX.

OWC’s new Envoy Pro SX Thunderbolt external drive delivers the speed of its Envoy Pro FX sibling, but for less cash. It features the same internal SSD, as well as the same rugged, IP67-rated dust and water-resistant enclosure, but lacks its brethren’s USB 3 compatibility.
The Envoy Pro SX is a good-looking, all-metal, charcoal gray enclosure. At approximately 4.5-inches long, 2.75-inches wide, and 0.6-inches thick, and 8.6 ounces, the SX is no dainty little thing. However, the heft bespeaks quality, and with non-skid runners on the bottom, keeps Envoy Pro SX keep it from sliding about.
The metal case also sheds heat very well. It was barely warm to the touch after our test suite was finished. On one end of the drive is the Type-C port (with the Thunderbolt Logo), and on the other the slim (and rather dim) power/activity LED.
The Envoy Pro SX is a Thunderbolt-only drive while its older sibling offers legacy USB compatibility as well.

Four different capacity drives grace the SX series: 240GB for $199, 480GB for $249, 1TB for $349, and 2TB for $529. Those prices reflect a $20 saving over the FX. Yup, only $20. That’s kind of surprising.
Performance
The SX features the same Aura Pro 12 NVMe SSD as the FX, so it’s the bridge chip (NVMe to Thunderbolt) that’s likely a bit different from the FX. A bit. It doesn’t support USB, so make that quite a bit different.
The Envoy Pro SX came formatted to exFAT, but performed much better when formatted to AFPS as in this run of BlackMagicDesign’s Disk Speed. This was measured on an M1 24-inch iMac. The FX was tested on an M1 Mac mini.
IDG
As you can see above, the Envoy Pro SX seems a faster reader than writer, though 1.5GBps writing is still quite fast for an external drive. Oddly, despite the same NVMe SSD inside, Disk Speed measured the FX at 2243MBps writing and 1832MBps reading. The FX was tested on a 16GB M1 Mac mini, and the SX on an 8GB M1 24-inch iMac, so we took those results with several grains of salt and ran more tests on sister publication PCWorld’s testbed using Windows-based benchmarks.
On the testbed, the Envoy Pro SX proved a hair faster in synthetic benchmarks such as CrystalDiskMark 6, though the difference is so small as to be irrelevant.
The Envoy Pro SX was ever so slightly faster than its FX sibling in CrystalDiskMark 6 but by so slim a margin as to be a largely meaningless comparison.
IDG
The SX proved slower than the FX in two of our 48GB transfer tests, and slower when all the times were totaled, however, again, the difference is minor. Connect the Envoy Pro SX, Envoy Pro SX, or Samsung X5 to your Thunderbolt port and you’d never notice a difference without a stopwatch.
The Envoy Pro SX did quite well on our 48GB transfer tests, beating the FX on two, and losing on two. The difference is marginal at best, and subjectively unnoticeable.
IDG
I’m throwing out the Disk Speed results and saying the FX and SX are virtually identical in performance. The fact that I’ve seen aberrant Disk Speed results on M1 Macs before makes me confident in that analysis.
Bottom line
The Envoy Pro SX is Thunderbolt storage for your Mac or suitably equipped PC whose performance compares very well with the competition. If your primary criterion is cost, it’s a good purchase. However, the Envoy Pro FX is only $20 more than the SX. I don’t know about you, but if I’m spending beaucoup money already, a couple of sawbucks more for far greater compatibility wouldn’t faze me in the least.
