That is interesting - although it does show it's limitations in Random Read performance and reads with sequential writes (which is what is the best indicator of actual performance in Windows), you score extremely high in latency (due to the low score), which is likely where you're getting the biggest bump. For example, on an admittedly older system running a 10K WD Raptor drive, I get a 5.9 - even though most of my scores are equal to, or better than, yours:
The difference appears to be the Latency scores, which your disk does much better in than mine, and in the overall time to run the tests (meaning your disk is a slight bit faster at doing I/O work, which is expected as well with more cache and a faster system).Code:Windows System Assessment Tool > Command Line 'winsat disk -v' > DWM running... leaving it on > System processor power policy saved and set to 'max performance' > Running: Feature Enumeration '' > Gathering System Information > Operating System : 6.1 Build-7600 > Processor : Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz > TSC Frequency : 0 > Number of Processors : 1 > Number of Cores : 4 > Number of CPUs : 4 > Number of Cores per Processor : 4 > Number of CPUs Per Core : 1 > Cores have logical CPUs : NO > L1 Cache and line Size : 32768 64 > L2 Cache and line Size : 6291456 64 > Total physical mem available to the OS : 7.99 GB (8,588,906,496 bytes) > Adapter Description : NVIDIA GeForce 9800 GT > Adapter Manufacturer : NVIDIA > Adapter Driver Version : 8.17.12.5896 > Adapter Driver Date (yy/mm/dd) : 2010\7\9 > Has DX9 or better : Yes > Has Pixel shader 2.0 or better : Yes > Has LDDM Driver : Yes > Dedicated (local) video memory : 487.563MB > System memory dedicated as video memory : 0MB > System memory shared as video memory : 3583.91MB > Primary Monitor Size : 1920 X 1200 (2304000 total pixels) > WinSAT is Official : Yes > Run Time 00:00:00.00 > Running: Storage Assessment '-seq -read -n 1' Mode Flags = 0x%08x Disk Number = 1 Iterations = 1 IO Count = 256 Sequential IO Size = 65536 Random IO Size = 16384 Run[1] Type[0x01080001] Zone[0] - 76.683222 MB/s Run[1] Type[0x01080001] Zone[1] - 66.957107 MB/s Run[1] Type[0x01080001] Zone[2] - 77.994069 MB/s Run[1] Type[0x01080001] Zone[3] - 67.773430 MB/s Run[1] Type[0x01080001] Zone[4] - 66.896293 MB/s Run[1] Type[0x01080001] Zone[5] - 65.292959 MB/s Run[1] Type[0x01080001] Zone[6] - 63.444812 MB/s Run[1] Type[0x01080001] Zone[7] - 54.540199 MB/s > Run Time 00:00:06.94 > Running: Storage Assessment '-ran -read -n 1' Mode Flags = 0x%08x Disk Number = 1 Iterations = 1 IO Count = 1000 Sequential IO Size = 65536 Random IO Size = 16384 Run[1] Type[0x01000002] Zone[0] - 2.101971 MB/s > Run Time 00:00:07.88 > Running: Storage Assessment '-scen 2009 -drive C:' Mode Flags = 0x%08x Disk Number = 1 Iterations = 1 IO Count = 9000 Sequential IO Size = 65536 Random IO Size = 16384 Requesting a file of size 1073741824 located at physical offset 0x8a7f80200.
