Seagate Momentus XT 750GB Solid State Hybrid Drive Review – SSD Performance With HDD Capacity
Luckily, the Momentus XT’s arrival coincided with the building of a new test bench. All of the precautions and settings were followed according to Seagate’s testing directions:
Todays benchmarks are going to be a bit…extensive…as we put the Momentus XT through the ropes with a wide variety of software to include HDTach, HDTune, AS SSD,ATTO, Crystal DiskMark, PCMark 7, PCMark Vantage, along with true to life tests with Adobe CS5 and 7-Zip.
HD TACH/HD TUNE READ/WRITE BENCHMARKS
HD Tach is a physical performance hard drive test which utilizes a special kernel mode VXD in order to get maximum accuracy by bypassing the file system. The HD Tach sequential read test reads from areas all over the hard drive and reports an average speed. HD Tach also tests the drive’s random access time, as well as its burst speed:
With the average speed being the most important factor, there is virtually no gain in sequential read performance over the first generation Momentus, which was expected. As before, the NAND does not contribute to the results of the new Momentus XT.
HD Tune is a hard disk utility which by means of a set of simple steps checks the status of hard drives (internal, external or extractable). Apart from checking the status, the application is measures the drive’s performance, errors during scanning, and health status. HD Tune writes over the full area of a hard drive, exposing any potential drawbacks the drive may have:
The AS-SSD benchmark determines the performance of Solid State Drives (SSD). The tool contains five synthetic and three practice tests, testing sequential read and write speeds, as well as input/output functionality and response times:
