IOMeter - Transaction rate
IOMeter presents a good test case for command queuing. To keep things easy to read, we've busted out two sets of graphs here. The first includes the Spinpoint and its closest competitors, while the second has results for all the drives we've tested. With over two dozen drives, those latter graphs are a little difficult to read, so we'll focus our attention on the first set and the F1's direct rivals.

Samsung doesn't intend for the Spinpoint F1 to be used in disk-intensive multi-user environments, and looking at the drive's IOMeter results, it's easy to see why. Only the Deskstar 7K1000 is slower than the Spinpoint here, and the Hitachi at least makes an effort to ramp transaction rates as we hit the highest loads. The F1's performance profile is much shallower by comparison, and well off the pace set by the bulk of the pack.

Good luck with these, folks.
