What you need to know

  • OWC announced the Envoy Pro SX SSD today.
  • The SSD gets read/write speeds up to 2,847 MB/s.
  • It's also water-resistant and has been tested for drops up to four feet.

All of the best SSDs are fast, but not all of them are durable. The newly announced OWC Envoy Pro SX SSD delivers read/write speeds up to 2,847 MB/s and is also water-resistant. On top of that, the new SSD was dropped 25 times from different angles from a height of four feet by a third-party for testing.

The OWC Envoy Pro SX 240GB is available now, starting at $199 for the 240GB model. The 480GB ($249), 1TB ($349), and 2TB ($529) models are also on sale.

OWC claims that the Envoy Pro SX delivers the "fastest and most reliable performance available in a portable drive."

The read/write speeds of up to 2,847 were hit by a 4TB SSD, according to OWC. Before purchasing a model with less storage, it's worth confirming if they have lower read/write speeds. Neither OWC nor the drive's product listing on MacSales clarify the speeds of models with less storage.

If you like the idea of a waterproof SSD but don't need the read/write speeds of the Envoy Pro SX, you can check out the OWC Envoy Pro Elektron. It's slower than the Envoy Pro SX, but it's still fast, getting read/write speeds around 1,053/933 MB/s. It has a lower starting price and is IP67 rated against dust and water.

  • So the speed was tested on a 4GB SSD, but the 4GB SSD isn't available for purchase, that's... odd.
