Will Thunderbolt affect random performance of ext. SSD?

    I know the pain to tear down the new iMac makes lots of people go for external SSDs. Instead of sequential r/w speed, my concern is the random speed. Since there is a bridge chip between SATA and Thunderbolt, I highly suspect this will definitely degrade SSD's performance when reading/writing lots of tiny files. Does anybody have a benchmark of that effect? After all, almost no respond time is the biggest edge over spinning HDDs.

    Highly doubt that it will be an issue. Apple has been shipping TB + internal SSD machines for quite some time now.

    Look around at anandtech.com. There are lots of SSD benchmarks and comparisons, you may find something representative there.

    What I mean is if I using external SSD to store my OS and entire system, will the TB be the bottle neck for random r/w?
