I have old CORSAIR F40 SSD that has theoretical speed of 280 MB/s for both read and write.
I bought this USB to SATA connector - http://www.amazon.co.uk/gp/product/B005OMXBN2 as USB 3.0 interface has 5 Gb/s theoretical transfer rate, I thought it should fully utilize this old SSD R/W speeds but it does not.
When I hook it up to my Mac mini (latest model that have USB 3.0) - max read speed is ~ 100 MB/s and write speed is ~ 50 MB/s.
I am not sure if the connector is the bottleneck or the SSD itself, so my question is - Will connecting a SSD drive using USB 3.0 to SATA connector achieve the same speed if it is connected to internal SATA port?
