TR DriveBench 2.0 — Disk-intensive multitasking
DriveBench 2.0 is a trace-based test comprised of nearly two weeks of typical desktop activity peppered with intense multitasking loads. More details on are available on this page of our last major SSD round-up.
We measure DriveBench performance by analyzing service times—the amount of time it takes drives to complete I/O requests. Those results are split into reads and writes.
Our mean service time metrics suggests the Neutron Series XT is very responsive with real-world I/O. Indeed, the XT has one of the quickest read service times we've ever measured in DriveBench. That's a stark contrast to the Force Series LS, which has by far the slowest service times with both reads and writes. The LS has an even higher mean write service time than the mechanical drives.
All the SSDs execute the vast majority of DriveBench requests in one millisecond or less—too little time for end users to perceive. We can also sort out the number of service times longer than 100 milliseconds, which is far more interesting data. These extremely long service times make up only a fraction of the overall total, but they're much more likely to be noticeable.
Although the Neutron Series XT doesn't suffer too many extremely long reads, it does exhibit more sluggish writes than most of the competition, including its GTX kin. The Neutron Series GTX logs just a single write service time over 100 milliseconds, compared to over ten thousand for the XT. At least the XT is in much better shape than the Force Series LS, which trades blows with the Crucial M500 at the very back of the field.
