ATTO DISK BENCHMARKS
The ATTO Disk Benchmark performance measurement tool measures total storage system performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously:
ATTO was set to a length of 256Mb transfer from 0.5Kb to 8192Kb. The results are the same as we have been seeing. NAND is just not utilized, not even in the ATTO benchmark. Take note that while the Momentus XT shows a sizeable improvement over the first generation Momentus (as it has shown in other benchmarks as well), it is essentially on par with the Western Digital Scorpio Black, again due to the fact that the SSD segment of the Momentus XT is not exercised
CrystalDiskMark is a small benchmark utility for hard drives (as well as flash drives) that enables rapid measurements of sequential and random read/write speeds:
Testing Adaptive Memory Technology requires running the same test about 10+ times in order to randomize the data. Even after all of those trials, the Momentus XT could not produce the same results as an SSD would.
