Seagate Momentus XT 750GB Hybrid Drive
PCMark 7 Storage Benchmarks
|
PCMark 7's storage benchmark, due to its psuedo-real-world workloads, does show the benefits of Seagate's adaptive memory technology. We ran this test three times to illustrate how the Momentus XT's performance scales from run to run as its solid state cache comes into play. The test was run multiple times on the other hybrid solutions as well, and the results from their third runs are reported here. The other hybrid solutions, however, offered somewhat better performance in most of the tests.
As you can see, the Momentus XT's performance scales significantly as its solid state cache is utilized and the drive offers performance much better than a standard 7200RPM hard drive.
