OWC Mercury Envoy Pro EX 1TB USB3 SSD
MPG tested the 1TB Envoy Pro, part number OWCENVPROU3S960. About $545.
A similar product is available as a 1TB internal SSD upgrade for certain models of MacBook Pro.
With bus power provided by the supplied short USB3 cable), it’s an ideal on the go drive—no power cable needed. Store the drive and its cable in the soft cloth pouch (included) and it can stow just about anywhere*.
Now OWC now introduces a 1TB capacity Envoy Pro in the same form factor, but at double the capacity and at a far lower price per gigabyte.
At about $468, it represents excellent value for its combined performance and compactness.
* Travelers: never store it with your laptop, since if the laptop is stolen, the drive is also stolen. Store in a pants or jacket pocket or anywhere but the bag containing the laptop.

- Ultra light, weighed at 106 grams, 126 grams with supplied USB3 cable.
- Easily fits into a pocket.
- Power and data with one USB 3 cable.
- No noise, no vibration, no heat.
- Consistent high performance at all I/O transfer sizes.

- Backward compatible with USB2 on older Macs (but USB2 is molasses-slow).
Speeds shown are real world performance through the OS X file system.
Performance for very large transfers is consistent in a tight band around 356 MB/sec, and exactly the same when writing high compressible zeroes or incompressible random data. Writes speed is the same as read speed (< 1% difference).
The Envoy Pro EX 480GB tests faster, at around 430 MB/sec, but its speed drops with incompressible data. The 1TB model delivers a consistent 356MB/sec with any type of data.

Speed vs transfer size
Performance for 32K transfer sizes is an important metric for some uses, so the results shown in the ~150MB/sec range are excellent. Peak performance is reached with 512K or larger transfers, which is typical.
