Bought one of these:

OWC Mercury Elite Pro mini
1.0TB 7200RPM
Bus-Powered, Multi-Interface Storage Solution
Mac / PC / USB 3.0 & 2.0

Got it hooked to the back of my late 2013 iMac and generally get the results shown below in the screen snap. Are these pretty much on the mark?

In my late 2012 model with USB 3 3Tb Seagate plugged in, I'm getting more than that. About 184 write and 187 read.

Looks about right for a non UASP enclosure.
