Alex Schepeljanski of Alex Intelligent Software develops the free AS SSD Benchmark utility for testing storage devices. The AS SSD Benchmark tests sequential read and write speeds, input/output operational performance, and response times. Because this software receives frequent updates, Benchmark Reviews recommends that you compare results only within the same version family.
For the purpose of testing Solid State Hybrid Drive (SSHD) products, we've concentrated more on transfer speeds and less on 4K IOPS. After running several sequential read and write benchmarks to cache the test, the Seagate Momentus XT 750GB reported consistent results that appeared to rely on hard disk performance. After ten cache tests, the Seagate Momentus XT hybrid drive continued producing a 102.26 MB/s read and 97.71 MB/s write speed.

Combining two Seagate Momentus XT 750GB Solid State Hybrid Drives into a striped RAID-0 array yields much faster sequential speeds: 213.65 MB/s read and 216.77 MB/s write. These results are slight more than double the performance of a single Momentus XT SSHD, which will make our other tests much more interesting to compare.

The chart below is sorted by total combined sequential performance, which illustrates the differences in basic read/write speeds:
