Iometer Results (Part 2)
In terms of average response time, there wasn't any marked improvement with the use of Thunderbolt technology. In fact, average I/O response time during 64K Streaming Reads/Writes tests were almost identical to the point their plotted graphs lined up.
There were slight albeit negligible improvements for the File and Web Servers tests as the higher bandwidth of the Thunderbolt ensured the drive's performance, in terms of average I/O response time, scaled consistently as the queue requests increased from one to five. Like we lamented on the earlier page, these tests don't mimic the typical buyer of this product and the tests were conducted to figure out if Thunderbolt made any difference at all.
